Linux下安装Zookeeper

一、Zookeeper下载

[root@localhost home]# wget http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz  
--2016-01-15 23:15:57--  http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.3.6/zookeeper-3.3.6.tar.gz  
正在解析主机 mirror.bit.edu.cn (mirror.bit.edu.cn)... 114.247.56.117  
正在连接 mirror.bit.edu.cn (mirror.bit.edu.cn)|114.247.56.117|:80... 已连接。  
已发出 HTTP 请求，正在等待回应... 200 OK

正在保存至: “zookeeper-3.3.6.tar.gz”

二、解压

[root@localhost home]# tar -zxvf zookeeper-3.3.6.tar.gz  

三、进入到conf目录

[root@localhost home]# cd zookeeper-3.3.6/conf 

四、拷贝zoo_samle.cfg为zoo.cfg

[root@localhost conf]# cp zoo_sample.cfg zoo.cfg 

五、编辑zoo.cfg文件

[root@localhost conf]# vi zoo.cfg  

修改为：

# 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.  
dataDir=/usr/zookeeper  
dataLogDir=/usr/zookeeper/log  
# the port at which the clients will connect  
clientPort=2181  

六、设置环境变量

[root@localhost conf]# export ZOOKEEPER_INSTALL=/home/zookeeper-3.3.6  
[root@localhost conf]# export PATH=$PATH:$ZOOKEEPER_INSTALL/bin 

七、启动

[root@localhost bin]# ./zkServer.sh start  
JMX enabled by default  
Using config: /opt/deploy/zookeeper-3.3.6/bin/../conf/zoo.cfg  
Starting zookeeper ... STARTED  
[root@localhost bin]# jps
4721 QuorumPeerMain
10332 Jps

启动成功！

八、测试zookeeper

[root@localhost bin]# ./zkCli.sh
