[Hadoop] CentOS7安装Zookeeper-3.4.5-cdh5.7.0（单节点）

 

1. Zookeeper下载安装

我的环境使用的套件版本是cdh5.7，所以zookeeper也选择对应的版本下载。

下载解压

[hadoop@hadoop01 software]$ wget http://archive.cloudera.com/cdh5/cdh/5/zookeeper-3.4.5-cdh5.7.0.tar.gz
[hadoop@hadoop01 software]$ tar -zxvf zookeeper-3.4.5-cdh5.7.0.tar.gz -C ~/app/

配置环境变量

[root@hadoop01 yum.repos.d]# vi /etc/profile
export ZK_HOME=/home/hadoop/app/zookeeper-3.4.5-cdh5.7.0
export PATH=$ZK_HOME/bin:$PATH
[root@hadoop01 yum.repos.d]# source /etc/profile

修改zookeeper配置

[hadoop@hadoop01 ~]$ cd ~/app/zookeeper-3.4.5-cdh5.7.0/
[hadoop@hadoop01 zookeeper-3.4.5-cdh5.7.0]$ cp conf/zoo_sample.cfg conf/zoo.cfg 
[hadoop@hadoop01 zookeeper-3.4.5-cdh5.7.0]$ vi conf/zoo.cfg 
dataDir=/home/hadoop/tmp/zookeeper

 

2. Zookeeper Server 启动停止

启动

[hadoop@hadoop01 bin]$ ./zkServer.sh start

停止

[hadoop@hadoop01 bin]$ ./zkServer.sh stop

重启

[hadoop@hadoop01 bin]$ ./zkServer.sh restart

查看状态

[hadoop@hadoop01 bin]$ ./zkServer.sh status
JMX enabled by default

3. Zookeeper Client启动

启动一个zk client，连接本地的zk server

[hadoop@hadoop01 bin]$ ./zkCli.sh
