Zookeeper配置安装步骤

1. 下载Zookeeper

下载zookeeper3.4.6,上传，解压到/opt

2. Zookeeper配置安装

1.进入zookeeper/conf,cp zoo_sample.cfg zoo.cfg
，修改zoo.cfg

[root@BaseNode conf]# vim zoo.cfg 

# 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=/var/tdp/zookeeper
# 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

#设置服务器内部通讯地址和节点，给zookeeper使用的#ps:注意这里的名字要和主机名一致
server.1=BaseNode:2888:3888
server.2=zknode1:2888:3888
server.3=zknode2:2888:3888
server.4=zknode3:2888:3888
~                          

3. 在/var/bdp/zookeeper下创建myid文件

以此在每个虚拟机下存入和server.num相同的数字。

4.修改/etc/hosts文件

10.4.17.100 BaseNode
10.4.17.101 zknode1
10.4.17.102 zknode2
10.4.17.103 zkNode3                                                             

5. 修改zookeeper环境变量配置

vim /etc/profile
在文件末尾添加：

#Zookeeper
export ZOOKEEPER_HOME=/opt/zookeeper-3.4.6
export PATH=$PATH:$ZOOKEEPER_HOME/bin

保存source /etc/profile.

6. 大功告成，试一下吧

zkServer.sh restart/start
再看一下运行状态，zkServer.sh status

停止机群，zkServer.sh stop。
