Window server中安装Redis的超详细教程

1.下载window版的安装包,选择下载msi版本安装即可。

官网不支持下载window版本,只能去github上下载:

window版redis

按步骤安装完毕即可。

2.打开服务，会看到redis服务已开启:

设置启动类型为自动.

这样每次机器重启,redis也将自动启动。 

3.安装可视化界面:another.redis.desktop.manager

这是一款免费的redis操作界面,可简单的查看redis数据库。

 3.设置云服务上的redis可进行远程连接:

为了后续的开发,应配置远程服务器上的redis可进行远程连接(可通过ip地址+端口号进行访问).

在安装目录下，找到redis.windows-service.conf配置文件

配置文件:

# redis configuration file example
 
# note on units: when memory size is needed, it is possible to specify
# it in the usual form of 1k 5gb 4m and so forth:
#
# 1k => 1000 bytes
# 1kb => 1024 bytes
# 1m => 1000000 bytes
# 1mb => 1024*1024 bytes
# 1g => 1000000000 bytes
# 1gb => 1024*1024*1024 bytes
#
# units are case insensitive so 1gb 1gb 1gb are all the same.

# include one or more other config files here.  this is useful if you
# have a standard template that goes to all redis servers but also need
# to customize a few per-server settings.  include files can include
# other files, so use this wisely.
#
# notice option "include" won't be rewritten by command "config rewrite"
# from admin or redis sentinel. since redis always uses the last processed
# line as value of a configuration directive, you'd better put includes
# at the beginning of this file to avoid overwriting config change at runtime.
#
# if instead you are interested in using includes to override configuration
# options, it is better to use include as the last line.

# on windows, daemonize and pidfile are not supported.
# however, you can run redis as a windows service, and specify a logfile.
# the logfile will contain the pid.
 
# accept connections on the specified port, default is 6379.
# if port 0 is specified redis will not listen on a tcp socket.
port 6379
 
# tcp listen() backlog.
#
# in high requests-per-second environments you need an high backlog in order
# to avoid slow clients connections issues. note that the linux kernel
# will silently truncate it to the value of /proc/sys/net/core/somaxconn so
# make sure to raise both the value of somaxconn and tcp_max_syn_backlog
# in order to get the desired effect.
tcp-backlog 511
 
# by default redis listens for connections from all the network interfaces
# available on the server. it is possible to listen to just one or multiple
# interfaces using the "bind" configuration directive, followed by one or
# more ip addresses.
#
# examples:
#
# bind 192.168.1.100 10.0.0.1
bind 0.0.0.0
 
# specify the path for the unix socket that will be used to listen for
# incoming connections. there is no default, so redis will not listen
# on a unix socket when not specified.
#
# unixsocket /tmp/redis.sock
# unixsocketperm 700
 
# close the connection after a client is idle for n seconds (0 to disable)
timeout 0
 
# tcp keepalive.
#
# if non-zero, use so_keepalive to send tcp acks to clients in absence
# of communication. this is useful for two reasons:
#
# 1) detect dead peers.
# 2) take the connection alive from the point of view of network
#    equipment in the middle.
#
# on linux, the specified value (in seconds) is the period used to send acks.
# note that to close the connection the double of the time is needed.
# on other kernels the period depends on the kernel configuration.
#
# a reasonable value for this option is 60 seconds.
tcp-keepalive 0
 
# specify the server verbosity level.
# this can be one of:
# debug (a lot of information, useful for development/testing)
# verbose (many rarely useful info, but not a mess like the debug level)
# notice (moderately verbose, what you want in production probably)
# warning (only very important / critical messages are logged)

# specify the log file name. also 'stdout' can be used to force
# redis to log on the standard output.

#
#   will save the db if both the given number of seconds and the given
#   number of write operations against the db occurred.
#
#   in the example below the behaviour will be to save:
#   after 900 sec (15 min) if at least 1 key changed
#   after 300 sec (5 min) if at least 10 keys changed
#   after 60 sec if at least 10000 keys changed
#
#   note: you can disable saving completely by commenting out all "save" lines.
#
#   it is also possible to remove all the previously configured save
#   points by adding a save directive with a single empty string argument
#   like in the following example:
#
#   save ""
 
save 900 1
save 300 10
save 60 10000
 
# by default redis will stop accepting writes if rdb snapshots are enabled
# (at least one save point) and the latest background save failed.
# this will make the user aware (in a hard way) that data is not persisting
# on disk properly, otherwise chances are that no one will notice and some
# disaster will happen.
#
# if the background saving process will start working again redis will
# automatically allow writes again.
#
# however if you have setup your proper monitoring of the redis server
# and persistence, you may want to disable this feature so that redis will

################################# replication #################################
 
# master-slave replication. use slaveof to make a redis instance a copy of
# another redis server. a few things to understand asap about redis replication.
#
# 1) redis replication is asynchronous, but you can configure a master to
#    stop accepting writes if it appears to be not connected with at least
#    a given number of slaves.
# 2) redis slaves are able to perform a partial resynchronization with the
#    master if the replication link is lost for a relatively small amount of
#    time. you may want to configure the replication backlog size (see the next
#    sections of this file) with a sensible value depending on your needs.
# 3) replication is automatic and does not need user intervention. after a
#    network partition slaves automatically try to reconnect to masters
#    and resynchronize with them.
#
# slaveof <masterip> <masterport>
 
# if the master is password protected (using the "requirepass" configuration
# directive below) it is possible to tell the slave to authenticate before
# starting the replication synchronization process, otherwise the master will
# refuse the slave request.
#
# masterauth <master-password>
 
# when a slave loses its connection with the master, or when the replication
# is still in progress, the slave can act in two different ways:
#
# 1) if slave-serve-stale-data is set to 'yes' (the default) the slave will
#    still reply to client requests, possibly with out of date data, or the
#    data set may just be empty if this is the first synchronization.
#
# 2) if slave-serve-stale-data is set to 'no' the slave will reply with
#    an error "sync with master in progress" to all the kind of commands
#    but to info and slaveof.
#
slave-serve-stale-data yes
 
# you can configure a slave instance to accept writes or not. writing against
# a slave instance may be useful to store some ephemeral data (because data
# written on a slave will be easily deleted after resync with the master) but
# may also cause problems if clients are writing to it because of a
# misconfiguration.
#
# since redis 2.6 by default slaves are read-only.
#
# note: read only slaves are not designed to be exposed to untrusted clients
# on the internet. it's just a protection layer against misuse of the instance.
# still a read only slave exports by default all the administrative commands
# such as config, debug, and so forth. to a limited extent you can improve
# security of read only slaves using 'rename-command' to shadow all the
# administrative / dangerous commands.
slave-read-only yes
 
# replication sync strategy: disk or socket.
#
# -------------------------------------------------------
# warning: diskless replication is experimental currently
# -------------------------------------------------------
#
# new slaves and reconnecting slaves that are not able to continue the replication
# process just receiving differences, need to do what is called a "full
# synchronization". an rdb file is transmitted from the master to the slaves.
# the transmission can happen in two different ways:
#
# 1) disk-backed: the redis master creates a new process that writes the rdb
#                 file on disk. later the file is transferred by the parent
#                 process to the slaves incrementally.
# 2) diskless: the redis master creates a new process that directly writes the
#              rdb file to slave sockets, without touching the disk at all.
#
# with disk-backed replication, while the rdb file is generated, more slaves
# can be queued and served with the rdb file as soon as the current child producing
# the rdb file finishes its work. with diskless replication instead once
# the transfer starts, new slaves arriving will be queued and a new transfer
# will start when the current one terminates.
#
# when diskless replication is used, the master waits a configurable amount of
# time (in seconds) before starting the transfer in the hope that multiple slaves
# will arrive and the transfer can be parallelized.
#
# with slow disks and fast (large bandwidth) networks, diskless replication
# works better.
repl-diskless-sync no
 
# when diskless replication is enabled, it is possible to configure the delay
# the server waits in order to spawn the child that transfers the rdb via socket
# to the slaves.
#
# this is important since once the transfer starts, it is not possible to serve
# new slaves arriving, that will be queued for the next rdb transfer, so the server
# waits a delay in order to let more slaves arrive.
#
# the delay is specified in seconds, and by default is 5 seconds. to disable
# it entirely just set it to 0 seconds and the transfer will start asap.
repl-diskless-sync-delay 5
 
# slaves send pings to server in a predefined interval. it's possible to change
# this interval with the repl_ping_slave_period option. the default value is 10
# seconds.
#
# repl-ping-slave-period 10
 
# the following option sets the replication timeout for:
#
# 1) bulk transfer i/o during sync, from the point of view of slave.
# 2) master timeout from the point of view of slaves (data, pings).
# 3) slave timeout from the point of view of masters (replconf ack pings).
#
# it is important to make sure that this value is greater than the value
# specified for repl-ping-slave-period otherwise a timeout will be detected
# every time there is low traffic between the master and the slave.
#
# repl-timeout 60
 
# disable tcp_nodelay on the slave socket after sync?
#
# if you select "yes" redis will use a smaller number of tcp packets and
# less bandwidth to send data to slaves. but this can add a delay for
# the data to appear on the slave side, up to 40 milliseconds with
# linux kernels using a default configuration.
#
# if you select "no" the delay for data to appear on the slave side will
# be reduced but more bandwidth will be used for replication.
#
# by default we optimize for low latency, but in very high traffic conditions
# or when the master and slaves are many hops away, turning this to "yes" may
# be a good idea.
repl-disable-tcp-nodelay no
 
# set the replication backlog size. the backlog is a buffer that accumulates
# slave data when slaves are disconnected for some time, so that when a slave
# wants to reconnect again, often a full resync is not needed, but a partial
# resync is enough, just passing the portion of data the slave missed while
# disconnected.
#
# the bigger the replication backlog, the longer the time the slave can be
# disconnected and later be able to perform a partial resynchronization.
#
# the backlog is only allocated once there is at least a slave connected.
#
# repl-backlog-size 1mb
 
# after a master has no longer connected slaves for some time, the backlog
# will be freed. the following option configures the amount of seconds that
# need to elapse, starting from the time the last slave disconnected, for
# the backlog buffer to be freed.
#
# a value of 0 means to never release the backlog.
#
# repl-backlog-ttl 3600
 
# the slave priority is an integer number published by redis in the info output.
# it is used by redis sentinel in order to select a slave to promote into a
# master if the master is no longer working correctly.
#
# a slave with a low priority number is considered better for promotion, so
# for instance if there are three slaves with priority 10, 100, 25 sentinel will
# pick the one with priority 10, that is the lowest.
#
# however a special priority of 0 marks the slave as not able to perform the
# role of master, so a slave with priority of 0 will never be selected by
# redis sentinel for promotion.
#
# by default the priority is 100.
slave-priority 100
 
# it is possible for a master to stop accepting writes if there are less than
# n slaves connected, having a lag less or equal than m seconds.
#
# the n slaves need to be in "online" state.
#
# the lag in seconds, that must be <= the specified value, is calculated from
# the last ping received from the slave, that is usually sent every second.
#
# this option does not guarantee that n replicas will accept the write, but
# will limit the window of exposure for lost writes in case not enough slaves
# are available, to the specified number of seconds.
#
# for example to require at least 3 slaves with a lag <= 10 seconds use:
#
# min-slaves-to-write 3
# min-slaves-max-lag 10
#
# setting one or the other to 0 disables the feature.
#
# by default min-slaves-to-write is set to 0 (feature disabled) and
# min-slaves-max-lag is set to 10.

#
# example:
#
# rename-command config b840fc02d524045429941cc15f59e41cb7be6c52
#
# it is also possible to completely kill a command by renaming it into

#
# rename-command config ""
#
# please note that changing the name of commands that are logged into the

################################### limits ####################################
 
# set the max number of connected clients at the same time. by default
# this limit is set to 10000 clients, however if the redis server is not
# able to configure the process file limit to allow for the specified limit
# the max number of allowed clients is set to the current file limit
# minus 32 (as redis reserves a few file descriptors for internal uses).
#
# once the limit is reached redis will close all the new connections sending
# an error 'max number of clients reached'.
#
# maxclients 10000
 
# if redis is to be used as an in-memory-only cache without any kind of
# persistence, then the fork() mechanism used by the background aof/rdb
# persistence is unnecessary. as an optimization, all persistence can be
# turned off in the windows version of redis. this will redirect heap
# allocations to the system heap allocator, and disable commands that would
# otherwise cause fork() operations: bgsave and bgrewriteaof.
# this flag may not be combined with any of the other flags that configure
# aof and rdb operations.
# persistence-available [(yes)|no]
 
# don't use more memory than the specified amount of bytes.
# when the memory limit is reached redis will try to remove keys
# according to the eviction policy selected (see maxmemory-policy).
#
# if redis can't remove keys according to the policy, or if the policy is
# set to 'noeviction', redis will start to reply with errors to commands
# that would use more memory, like set, lpush, and so on, and will continue
# to reply to read-only commands like get.
#
# this option is usually useful when using redis as an lru cache, or to set
# a hard memory limit for an instance (using the 'noeviction' policy).
#
# warning: if you have slaves attached to an instance with maxmemory on,
# the size of the output buffers needed to feed the slaves are subtracted
# from the used memory count, so that network problems / resyncs will
# not trigger a loop where keys are evicted, and in turn the output
# buffer of slaves is full with dels of keys evicted triggering the deletion
# of more keys, and so forth until the database is completely emptied.
#
# in short... if you have slaves attached it is suggested that you set a lower
# limit for maxmemory so that there is some free ram on the system for slave
# output buffers (but this is not needed if the policy is 'noeviction').
#
# warning: not setting maxmemory will cause redis to terminate with an
# out-of-memory exception if the heap limit is reached.
#
# note: since redis uses the system paging file to allocate the heap memory,
# the working set memory usage showed by the windows task manager or by other
# tools such as processexplorer will not always be accurate. for example, right
# after a background save of the rdb or the aof files, the working set value
# may drop significantly. in order to check the correct amount of memory used
# by the redis-server to store the data, use the info client command. the info
# command shows only the memory used to store the redis data, not the extra
# memory used by the windows process for its own requirements. th3 extra amount
# of memory not reported by the info command can be calculated subtracting the
# peak working set reported by the windows task manager and the used_memory_peak
# reported by the info command.
#
maxmemory 100mb
 
# maxmemory policy: how redis will select what to remove when maxmemory
# is reached. you can select among five behaviors:
#
# volatile-lru -> remove the key with an expire set using an lru algorithm
# allkeys-lru -> remove any key according to the lru algorithm
# volatile-random -> remove a random key with an expire set
# allkeys-random -> remove a random key, any key
# volatile-ttl -> remove the key with the nearest expire time (minor ttl)
# noeviction -> don't expire at all, just return an error on write operations
#
# note: with any of the above policies, redis will return an error on write
#       operations, when there are no suitable keys for eviction.
#
#       at the date of writing these commands are: set setnx setex append
#       incr decr rpush lpush rpushx lpushx linsert lset rpoplpush sadd
#       sinter sinterstore sunion sunionstore sdiff sdiffstore zadd zincrby
#       zunionstore zinterstore hset hsetnx hmset hincrby incrby decrby
#       getset mset msetnx exec sort
#
# the default is:
#
# maxmemory-policy noeviction
 
# lru and minimal ttl algorithms are not precise algorithms but approximated
# algorithms (in order to save memory), so you can select as well the sample
# size to check. for instance for default redis will check three keys and
# pick the one that was used less recently, you can change the sample size
# using the following configuration directive.
#
# maxmemory-samples 3
 
############################## append only mode ###############################
 
# by default redis asynchronously dumps the dataset on disk. this mode is
# good enough in many applications, but an issue with the redis process or
# a power outage may result into a few minutes of writes lost (depending on
# the configured save points).
#
# the append only file is an alternative persistence mode that provides
# much better durability. for instance using the default data fsync policy
# (see later in the config file) redis can lose just one second of writes in a
# dramatic event like a server power outage, or a single write if something
# wrong with the redis process itself happens, but the operating system is
# still running correctly.
#
# aof and rdb persistence can be enabled at the same time without problems.
# if the aof is enabled on startup redis will load the aof, that is the file
# with the better durability guarantees.
#
# please check http://redis.io/topics/persistence for more information.
 
appendonly no
 
# the name of the append only file (default: "appendonly.aof")
appendfilename "appendonly.aof"
 
# the fsync() call tells the operating system to actually write data on disk
# instead of waiting for more data in the output buffer. some os will really flush
# data on disk, some other os will just try to do it asap.
#
# redis supports three different modes:
#
# no: don't fsync, just let the os flush the data when it wants. faster.
# always: fsync after every write to the append only log . slow, safest.
# everysec: fsync only one time every second. compromise.
#
# the default is "everysec", as that's usually the right compromise between
# speed and data safety. it's up to you to understand if you can relax this to
# "no" that will let the operating system flush the output buffer when
# it wants, for better performances (but if you can live with the idea of
# some data loss consider the default persistence mode that's snapshotting),
# or on the contrary, use "always" that's very slow but a bit safer than
# everysec.
#
# more details please check the following article:
# http://antirez.com/post/redis-persistence-demystified.html
#
# if unsure, use "everysec".
 
# appendfsync always
appendfsync everysec
# appendfsync no
 
# when the aof fsync policy is set to always or everysec, and a background
# saving process (a background save or aof log background rewriting) is
# performing a lot of i/o against the disk, in some linux configurations
# redis may block too long on the fsync() call. note that there is no fix for
# this currently, as even performing fsync in a different thread will block
# our synchronous write(2) call.
#
# in order to mitigate this problem it's possible to use the following option
# that will prevent fsync() from being called in the main process while a
# bgsave or bgrewriteaof is in progress.
#
# this means that while another child is saving, the durability of redis is
# the same as "appendfsync none". in practical terms, this means that it is
# possible to lose up to 30 seconds of log in the worst scenario (with the
# default linux settings).
#
# if you have latency problems turn this to "yes". otherwise leave it as
# "no" that is the safest pick from the point of view of durability.
no-appendfsync-on-rewrite no
 
# automatic rewrite of the append only file.
# redis is able to automatically rewrite the log file implicitly calling
# bgrewriteaof when the aof log size grows by the specified percentage.
#
# this is how it works: redis remembers the size of the aof file after the
# latest rewrite (if no rewrite has happened since the restart, the size of
# the aof at startup is used).
#
# this base size is compared to the current size. if the current size is
# bigger than the specified percentage, the rewrite is triggered. also
# you need to specify a minimal size for the aof file to be rewritten, this
# is useful to avoid rewriting the aof file even if the percentage increase
# is reached but it is still pretty small.
#
# specify a percentage of zero in order to disable the automatic aof
# rewrite feature.

# an aof file may be found to be truncated at the end during the redis
# startup process, when the aof data gets loaded back into memory.
# this may happen when the system where redis is running
# crashes, especially when an ext4 filesystem is mounted without the
# data=ordered option (however this can't happen when redis itself
# crashes or aborts but the operating system still works correctly).
#
# redis can either exit with an error when this happens, or load as much
# data as possible (the default now) and start if the aof file is found
# to be truncated at the end. the following option controls this behavior.
#
# if aof-load-truncated is set to yes, a truncated aof file is loaded and
# the redis server starts emitting a log to inform the user of the event.
# otherwise if the option is set to no, the server aborts with an error
# and refuses to start. when the option is set to no, the user requires
# to fix the aof file using the "redis-check-aof" utility before to restart
# the server.
#
# note that if the aof file will be found to be corrupted in the middle
# the server will still exit with an error. this option only applies when
# redis will try to read more data from the aof file but not enough bytes
# will be found.

# cluster node timeout is the amount of milliseconds a node must be unreachable
# for it to be considered in failure state.
# most other internal time limits are multiple of the node timeout.
#
# cluster-node-timeout 15000
 
# a slave of a failing master will avoid to start a failover if its data
# looks too old.
#
# there is no simple way for a slave to actually have a exact measure of
# its "data age", so the following two checks are performed:
#
# 1) if there are multiple slaves able to failover, they exchange messages
#    in order to try to give an advantage to the slave with the best
#    replication offset (more data from the master processed).
#    slaves will try to get their rank by offset, and apply to the start
#    of the failover a delay proportional to their rank.
#
# 2) every single slave computes the time of the last interaction with
#    its master. this can be the last ping or command received (if the master
#    is still in the "connected" state), or the time that elapsed since the
#    disconnection with the master (if the replication link is currently down).
#    if the last interaction is too old, the slave will not try to failover
#    at all.
#
# the point "2" can be tuned by user. specifically a slave will not perform
# the failover if, since the last interaction with the master, the time
# elapsed is greater than:
#
#   (node-timeout * slave-validity-factor) + repl-ping-slave-period
#
# so for example if node-timeout is 30 seconds, and the slave-validity-factor
# is 10, and assuming a default repl-ping-slave-period of 10 seconds, the
# slave will not try to failover if it was not able to talk with the master
# for longer than 310 seconds.
#
# a large slave-validity-factor may allow slaves with too old data to failover
# a master, while a too small value may prevent the cluster from being able to
# elect a slave at all.
#
# for maximum availability, it is possible to set the slave-validity-factor
# to a value of 0, which means, that slaves will always try to failover the
# master regardless of the last time they interacted with the master.
# (however they'll always try to apply a delay proportional to their
# offset rank).
#
# zero is the only value able to guarantee that when all the partitions heal
# the cluster will always be able to continue.
#
# cluster-slave-validity-factor 10
 
# cluster slaves are able to migrate to orphaned masters, that are masters
# that are left without working slaves. this improves the cluster ability
# to resist to failures as otherwise an orphaned master can't be failed over
# in case of failure if it has no working slaves.
#
# slaves migrate to orphaned masters only if there are still at least a
# given number of other working slaves for their old master. this number
# is the "migration barrier". a migration barrier of 1 means that a slave
# will migrate only if there is at least 1 other working slave for its master
# and so forth. it usually reflects the number of slaves you want for every
# master in your cluster.
#
# default is 1 (slaves migrate only if their masters remain with at least
# one slave). to disable migration just set it to a very large value.
# a value of 0 can be set but is useful only for debugging and dangerous
# in production.
#
# cluster-migration-barrier 1
 
# by default redis cluster nodes stop accepting queries if they detect there
# is at least an hash slot uncovered (no available node is serving it).
# this way if the cluster is partially down (for example a range of hash slots
# are no longer covered) all the cluster becomes, eventually, unavailable.
# it automatically returns available as soon as all the slots are covered again.
#
# however sometimes you want the subset of the cluster which is working,
# to continue to accept queries for the part of the key space that is still
# covered. in order to do so, just set the cluster-require-full-coverage
# option to no.
#
# cluster-require-full-coverage yes
 
# in order to setup your cluster make sure to read the documentation
# available at http://redis.io web site.
 
################################## slow log ###################################
 
# the redis slow log is a system to log queries that exceeded a specified
# execution time. the execution time does not include the i/o operations
# like talking with the client, sending the reply and so forth,
# but just the time needed to actually execute the command (this is the only
# stage of command execution where the thread is blocked and can not serve
# other requests in the meantime).
#
# you can configure the slow log with two parameters: one tells redis
# what is the execution time, in microseconds, to exceed in order for the
# command to get logged, and the other parameter is the length of the
# slow log. when a new command is logged the oldest one is removed from the
# queue of logged commands.
 
# the following time is expressed in microseconds, so 1000000 is equivalent
# to one second. note that a negative number disables the slow log, while
# a value of zero forces the logging of every command.
slowlog-log-slower-than 10000
 
# there is no limit to this length. just be aware that it will consume memory.
# you can reclaim memory used by the slow log with slowlog reset.

################################ latency monitor ##############################
 
# the redis latency monitoring subsystem samples different operations
# at runtime in order to collect data related to possible sources of
# latency of a redis instance.
#
# via the latency command this information is available to the user that can
# print graphs and obtain reports.
#
# the system only logs operations that were performed in a time equal or
# greater than the amount of milliseconds specified via the
# latency-monitor-threshold configuration directive. when its value is set
# to zero, the latency monitor is turned off.
#
# by default latency monitoring is disabled since it is mostly not needed
# if you don't have latency issues, and collecting data has a performance
# impact, that while very small, can be measured under big load. latency
# monitoring can easily be enabled at runtime using the command
# "config set latency-monitor-threshold <milliseconds>" if needed.
latency-monitor-threshold 0
 
############################# event notification ##############################
 
# redis can notify pub/sub clients about events happening in the key space.
# this feature is documented at http://redis.io/topics/notifications
#
# for instance if keyspace events notification is enabled, and a client
# performs a del operation on key "foo" stored in the database 0, two
# messages will be published via pub/sub:
#
# publish __keyspace@0__:foo del
# publish __keyevent@0__:del foo
#
# it is possible to select the events that redis will notify among a set
# of classes. every class is identified by a single character:
#
#  k     keyspace events, published with __keyspace@<db>__ prefix.
#  e     keyevent events, published with __keyevent@<db>__ prefix.
#  g     generic commands (non-type specific) like del, expire, rename, ...
#  $     string commands
#  l     list commands
#  s     set commands
#  h     hash commands
#  z     sorted set commands
#  x     expired events (events generated every time a key expires)
#  e     evicted events (events generated when a key is evicted for maxmemory)
#  a     alias for g$lshzxe, so that the "ake" string means all the events.
#
#  the "notify-keyspace-events" takes as argument a string that is composed
#  of zero or multiple characters. the empty string means that notifications
#  are disabled.
#
#  example: to enable list and generic events, from the point of view of the
#           event name, use:
#
#  notify-keyspace-events elg
#
#  example 2: to get the stream of the expired keys subscribing to channel
#             name __keyevent@0__:expired use:
#
#  notify-keyspace-events ex
#
#  by default all notifications are disabled because most users don't need
#  this feature and the feature has some overhead. note that if you don't
#  specify at least one of k or e, no events will be delivered.

############################### advanced config ###############################
 
# hashes are encoded using a memory efficient data structure when they have a
# small number of entries, and the biggest entry does not exceed a given
# threshold. these thresholds can be configured using the following directives.
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
 
# similarly to hashes, small lists are also encoded in a special way in order
# to save a lot of space. the special representation is only used when
# you are under the following limits:
list-max-ziplist-entries 512
list-max-ziplist-value 64
 
# sets have a special encoding in just one case: when a set is composed
# of just strings that happen to be integers in radix 10 in the range
# of 64 bit signed integers.
# the following configuration setting sets the limit in the size of the
# set in order to use this special memory saving encoding.
set-max-intset-entries 512
 
# similarly to hashes and lists, sorted sets are also specially encoded in
# order to save a lot of space. this encoding is only used when the length and
# elements of a sorted set are below the following limits:
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
 
# hyperloglog sparse representation bytes limit. the limit includes the
# 16 bytes header. when an hyperloglog using the sparse representation crosses
# this limit, it is converted into the dense representation.
#
# a value greater than 16000 is totally useless, since at that point the
# dense representation is more memory efficient.
#
# the suggested value is ~ 3000 in order to have the benefits of
# the space efficient encoding without slowing down too much pfadd,
# which is o(n) with the sparse encoding. the value can be raised to
# ~ 10000 when cpu is not a concern, but space is, and the data set is
# composed of many hyperloglogs with cardinality in the 0 - 15000 range.
hll-sparse-max-bytes 3000
 
# active rehashing uses 1 millisecond every 100 milliseconds of cpu time in
# order to help rehashing the main redis hash table (the one mapping top-level
# keys to values). the hash table implementation redis uses (see dict.c)
# performs a lazy rehashing: the more operation you run into a hash table
# that is rehashing, the more rehashing "steps" are performed, so if the
# server is idle the rehashing is never complete and some more memory is used
# by the hash table.
#
# the default is to use this millisecond 10 times every second in order to
# actively rehash the main dictionaries, freeing memory when possible.
#
# if unsure:
# use "activerehashing no" if you have hard latency requirements and it is
# not a good thing in your environment that redis can reply from time to time
# to queries with 2 milliseconds delay.
#
# use "activerehashing yes" if you don't have such hard requirements but
# want to free memory asap when possible.
activerehashing yes
 
# the client output buffer limits can be used to force disconnection of clients
# that are not reading data from the server fast enough for some reason (a
# common reason is that a pub/sub client can't consume messages as fast as the
# publisher can produce them).
#
# the limit can be set differently for the three different classes of clients:
#
# normal -> normal clients including monitor clients
# slave  -> slave clients
# pubsub -> clients subscribed to at least one pubsub channel or pattern
#
# the syntax of every client-output-buffer-limit directive is the following:
#
# client-output-buffer-limit <class> <hard limit> <soft limit> <soft seconds>
#
# a client is immediately disconnected once the hard limit is reached, or if
# the soft limit is reached and remains reached for the specified number of
# seconds (continuously).
# so for instance if the hard limit is 32 megabytes and the soft limit is
# 16 megabytes / 10 seconds, the client will get disconnected immediately
# if the size of the output buffers reach 32 megabytes, but will also get
# disconnected if the client reaches 16 megabytes and continuously overcomes
# the limit for 10 seconds.
#
# by default normal clients are not limited because they don't receive data
# without asking (in a push way), but just after a request, so only
# asynchronous clients may create a scenario where data is requested faster
# than it can read.
#
# instead there is a default limit for pubsub and slave clients, since
# subscribers and slaves receive data in a push fashion.
#
# both the hard or the soft limit can be disabled by setting them to zero.
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
 
# redis calls an internal function to perform many background tasks, like
# closing connections of clients in timeot, purging expired keys that are
# never requested, and so forth.
#
# not all tasks are perforemd with the same frequency, but redis checks for
# tasks to perform according to the specified "hz" value.
#
# by default "hz" is set to 10. raising the value will use more cpu when
# redis is idle, but at the same time will make redis more responsive when
# there are many keys expiring at the same time, and timeouts may be
# handled with more precision.
#
# the range is between 1 and 500, however a value over 100 is usually not
# a good idea. most users should use the default of 10 and raise this up to
# 100 only in environments where very low latency is required.
hz 10
 
# when a child rewrites the aof file, if the following option is enabled
# the file will be fsync-ed every 32 mb of data generated. this is useful
# in order to commit the file to the disk more incrementally and avoid
# big latency spikes.
