Windows上redis 安装与PHP使用

Windows下redis 安装与PHP使用

一、 安装redis及启用服务

1 下载redis客户端

?

http://code.google.com/p/servicestack/wiki/RedisWindowsDownload#Download_32bit_Cygwin_builds_for_Windows

?

2 解压到你所需要的目录中

?

3 创建redis.conf文件

# Redis configuration file example# By default Redis does not run as a daemon. Use 'yes' if you need it.# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.daemonize no# When run as a daemon, Redis write a pid file in /var/run/redis.pid by default.# You can specify a custom pid file location here.pidfile /var/run/redis.pid# Accept connections on the specified port, default is 6379port 6379# If you want you can bind a single interface, if the bind option is not# specified all the interfaces will listen for connections.## bind 127.0.0.1# Close the connection after a client is idle for N seconds (0 to disable)timeout 300# Set server verbosity to 'debug'# it can be one of:# debug (a lot of information, useful for development/testing)# notice (moderately verbose, what you want in production probably)# warning (only very important / critical messages are logged)loglevel debug# Specify the log file name. Also 'stdout' can be used to force# the demon to log on the standard output. Note that if you use standard# output for logging but daemonize, logs will be sent to /dev/nulllogfile stdout# Set the number of databases. The default database is DB 0, you can select# a different one on a per-connection basis using SELECT  where# dbid is a number between 0 and 'databases'-1databases 16################################ SNAPSHOTTING  ################################### Save the DB on disk:##   save ##   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 changedsave 900 1save 300 10save 60 10000# Compress string objects using LZF when dump .rdb databases?# For default that's set to 'yes' as it's almost always a win.# If you want to save some CPU in the saving child set it to 'no' but# the dataset will likely be bigger if you have compressible values or keys.rdbcompression yes# The filename where to dump the DBdbfilename dump.rdb# For default save/load DB in/from the working directory# Note that you must specify a directory not a file name.dir ./################################# REPLICATION ################################## Master-Slave replication. Use slaveof to make a Redis instance a copy of# another Redis server. Note that the configuration is local to the slave# so for example it is possible to configure the slave to save the DB with a# different interval, or to listen to another port, and so on.## slaveof # 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 ################################## SECURITY #################################### Require clients to issue AUTH  before processing any other# commands.  This might be useful in environments in which you do not trust# others with access to the host running redis-server.## This should stay commented out for backward compatibility and because most# people do not need auth (e.g. they run their own servers).## requirepass foobared################################### LIMITS ##################################### Set the max number of connected clients at the same time. By default there# is no limit, and it's up to the number of file descriptors the Redis process# is able to open. The special value '0' means no limts.# Once the limit is reached Redis will close all the new connections sending# an error 'max number of clients reached'.## maxclients 128# Don't use more memory than the specified amount of bytes.# When the memory limit is reached Redis will try to remove keys with an# EXPIRE set. It will try to start freeing keys that are going to expire# in little time and preserve keys with a longer time to live.# Redis will also try to remove objects from free lists if possible.## If all this fails, Redis will start to reply with errors to commands# that will use more memory, like SET, LPUSH, and so on, and will continue# to reply to most read-only commands like GET.## WARNING: maxmemory can be a good idea mainly if you want to use Redis as a# 'state' server or cache, not as a real DB. When Redis is used as a real# database the memory usage will grow over the weeks, it will be obvious if# it is going to use too much memory in the long run, and you'll have the time# to upgrade. With maxmemory after the limit is reached you'll start to get# errors for write operations, and this may even lead to DB inconsistency.## maxmemory ############################## APPEND ONLY MODE ################################ By default Redis asynchronously dumps the dataset on disk. If you can live# with the idea that the latest records will be lost if something like a crash# happens this is the preferred way to run Redis. If instead you care a lot# about your data and don't want to that a single record can get lost you should# enable the append only mode: when this mode is enabled Redis will append# every write operation received in the file appendonly.log. This file will# be read on startup in order to rebuild the full dataset in memory.## Note that you can have both the async dumps and the append only file if you# like (you have to comment the "save" statements above to disable the dumps).# Still if append only mode is enabled Redis will load the data from the# log file at startup ignoring the dump.rdb file.## The name of the append only file is "appendonly.log"## IMPORTANT: Check the BGREWRITEAOF to check how to rewrite the append# log file in background when it gets too big.appendonly no# The fsync() call tells the Operating System to actually write data on disk# instead to wait 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 if one second passed since the last fsync. Compromise.## The default is "always" that's the safer of the options. It's up to you to# understand if you can relax this to "everysec" that will fsync every second# or to "no" that will let the operating system flush the output buffer when# it want, for better performances (but if you can live with the idea of# some data loss consider the default persistence mode that's snapshotting).appendfsync always# appendfsync everysec# appendfsync no############################### ADVANCED CONFIG ################################ Glue small output buffers together in order to send small replies in a# single TCP packet. Uses a bit more CPU but most of the times it is a win# in terms of number of queries per second. Use 'yes' if unsure.glueoutputbuf yes# Use object sharing. Can save a lot of memory if you have many common# string in your dataset, but performs lookups against the shared objects# pool so it uses more CPU and can be a bit slower. Usually it's a good# idea.## When object sharing is enabled (shareobjects yes) you can use# shareobjectspoolsize to control the size of the pool used in order to try# object sharing. A bigger pool size will lead to better sharing capabilities.# In general you want this value to be at least the double of the number of# very common strings you have in your dataset.## WARNING: object sharing is experimental, don't enable this feature# in production before of Redis 1.0-stable. Still please try this feature in# your development environment so that we can test it better.# shareobjects no# shareobjectspoolsize 1024

?4 在命令行下启动服务

? ??

启动成功后显示（此窗口会一直滚动，不要关闭，否则redis就停止了）

?

5 设置redis服务客户端

?

之后会显示

?

6 测试

?

window下安装成功

?

二、PHP中使用

1 添加phpredis扩展

?首先，查看所用php编译版本V6/V9 在phpinfo()中查看

?

?

2 下载扩展 地址：https://github.com/nicolasff/phpredis/downloads（注意所支持的php版本）

?

3 将下载的php_redis.dll放在php扩展目录中（ext），并修改配置文件php.ini（添加extension=php_redis.dll）

?

4 重新启动服务，查看phpinfo(),下面表示成功；

?

?

5 用PHP测试

?

$redis = new Redis();$redis->connect("192.168.138.2","6379");  //php客户端设置的ip及端口//存储一个 值$redis->set("say","Hello World");echo $redis->get("say");     //应输出Hello World//存储多个值$array = array('first_key'=>'first_val',          'second_key'=>'second_val',          'third_key'=>'third_val');$array_get = array('first_key','second_key','third_key');$redis->mset($array);var_dump($redis->mget($array_get));

?

linux下待实践无误以后奉上
