ZooKeeper 是什么?

ZooKeeper是一个分布式的,开放源码的分布式应用程序协调服务,是Google的Chubby一个开源的实现,是Hadoop和Hbase的重要组件。它是一个为分布式应用提供一致性服务的软件,提供的功能包括:配置维护、域名服务、分布式同步、组服务等。
ZooKeeper的目标就是封装好复杂易出错的关键服务,将简单易用的接口和性能高效、功能稳定的系统提供给用户。
ZooKeeper包含一个简单的原语集,提供Java和C的接口。
ZooKeeper代码版本中,提供了分布式独享锁、选举、队列的接口,代码在zookeeper-3.4.8\src\recipes。其中分布锁和队列有Java和C两个版本,选举只有Java版本。

解压到E:\zookeeper-3.4.13\zookeeper-3.4.13
修改配置文件
复制zoo_sample.cfg 文件名(E:\zookeeper-3.4.13\zookeeper-3.4.13\conf) 为 zoo.cfg
主要修改一下日志位置,具体配置文件如下:

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=E:\\zookeeper\\data
dataLogDir=E:\\zookeeper\\log
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

配置文件简单解析
1、tickTime:这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔,也就是每个 tickTime 时间就会发送一个心跳。
2、dataDir:顾名思义就是 Zookeeper 保存数据的目录,默认情况下,Zookeeper 将写数据的日志文件也保存在这个目录里。
3、dataLogDir:顾名思义就是 Zookeeper 保存日志文件的目录
4、clientPort:这个端口就是客户端连接 Zookeeper 服务器的端口,Zookeeper 会监听这个端口,接受客户端的访问请求。

打开powershell 查看一下zookeeper的整体目录

PS E:\> cd .\zookeeper-3.4.13\
PS E:\zookeeper-3.4.13> ls

简单介绍连个目录:
bin:可执行脚本
conf:配置文件(刚才已经在conf做了一个简单的配置)
如何启动zookeeper呢?
执行脚本需要进入bin

PS E:\zookeeper-3.4.13\zookeeper-3.4.13> cd bin
PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> ls


    目录: E:\zookeeper-3.4.13\zookeeper-3.4.13\bin


Mode                LastWriteTime         Length Name
----                -------------         ------ ----

-a----        2018/6/30      1:04           1937 zkCleanup.sh

-a----        2018/6/30      1:04           1089 zkServer.cmd
-a----        2018/6/30      1:04           6773 zkServer.sh
-a----        2018/6/30      1:04            996 zkTxnLogToolkit.cmd
-a----        2018/6/30      1:04           1385 zkTxnLogToolkit.sh

可以看到在bin的下面既有sh,又有cmd,说明zookeeper支持linux和win两类系统
启动一下试试:

PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> .\zkServer.cmd

使用zkCli.cmd 客户端连接zookeeper报错

PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> .\zkCli.cmd 127.0.0.0.1:2181

解决办法:
1、换低版本
2、此版本没有找到很好的解决方案。。。待续
另一种方法:

PS E:\zookeeper-3.4.13\zookeeper-3.4.13\bin> jps -l -v
17828 sun.tools.jps.Jps -Dapplication.home=C:\Program Files\Java\jdk1.8.0_161 -Xms8m
25004 org.apache.zookeeper.server.quorum.QuorumPeerMain -Dzookeeper.log.dir=E:\zookeeper-3.4.13\zookeeper-3.4.13\bin\.. -Dzookeeper.root.logger=INFO,CONSOLE

可以看到QuorumPeerMain的进程
