好，下面上货。前面已经介绍了zookeeper的基本使用和单节点环境的搭建，现在介绍一下伪分布式环境的zookeeper是如何搭建的。

1、首先下载zookeeper最新版本的3.4.10

![Center][]

2、解压到指定文件夹，这里解压到/data文件夹下。同时复制2份。

![Center 1][]

3、修改配置文件conf文件下的zoo.cfg文件。

配置文件1：

\# 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=/data/zoodata1  
dataLogDir=/data/zoodata1/logs  
\# 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  
server.1=127.0.0.1:4000:5000    
server.2=127.0.0.1:4001:5001    
server.3=127.0.0.1:4002:5002

配置文件2

\# 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=/data/zoodata2  
dataLogDir=/data/zoodata2/logs  
\# the port at which the clients will connect  
clientPort=2182  
\# 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  
server.1=127.0.0.1:4000:5000    
server.2=127.0.0.1:4001:5001    
server.3=127.0.0.1:4002:5002

配置文件3：

\# 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=/data/zoodata3  
dataLogDir=/data/zoodata3/logs  
\# the port at which the clients will connect  
clientPort=2183  
\# 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  
server.1=127.0.0.1:4000:5000    
server.2=127.0.0.1:4001:5001    
server.3=127.0.0.1:4002:5002

4、然后根据配置的datadir和datalogdir进行创建文件夹。

![Center 2][]

5、启动zookeeper，启动的时候分别启动每一个./zkServer.sh start

6、查看节点状态，查看哪个是leader，哪个是follower。

echo stat | nc 192.168.0.99 2181

![Center 3][]

echo stat | nc 192.168.0.99 2182

![Center 4][]

echo stat | nc 192.168.0.99 2183

![Center 5][]

ok！这样就完成了zookeeper的伪分布式搭建。
