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  长度：11833706 (11M) [application/octet-stream]  正在保存至: “zookeeper-3.3.6.tar.gz”    100%[======================================================================================================================================================================================>] 11,833,706   171KB/s 用时 68s        2016-01-15 23:17:07 (170 KB/s) - 已保存 “zookeeper-3.3.6.tar.gz” [11833706/11833706])  

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]# jps4721 QuorumPeerMain10332 Jps

启动成功！

八、测试zookeeper

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