ZooKeeper安装
集群配置
| hadoop1 | hadoop2 | hadoop3 | |
| Zookeeper ID | 1 | 2 | 3 |
上传ZK
解压缩
[hadoop@hadoop1 ~]$ tar -zxvf /opt/soft/zookeeper-3.4.10.tar.gz -C /opt/module
设置Data路径
[hadoop@hadoop1 ~]$ cd /opt/module/zookeeper-3.4.10/
[hadoop@hadoop1 zookeeper-3.4.10]$ mkdir zkData
设置节点的ID
[hadoop@hadoop1 zookeeper-3.4.10]$ cd zkData
[hadoop@hadoop1 zkData]$ vi myid
[hadoop@hadoop1 zookeeper-3.4.10]$ pwd
/opt/module/zookeeper-3.4.10
[hadoop@hadoop1 zookeeper-3.4.10]$ cd conf
[hadoop@hadoop1 conf]$ cp zoo_sample.cfg zoo.cfg

设置环境变量
[hadoop@hadoop1 bin]$ sudo vi /etc/profile
[hadoop@hadoop1 bin]$ source /etc/profile
分发
[hadoop@hadoop1 conf]$ xrsync.sh /opt/module/zookeeper-3.4.10/
配置节点ID
将hadoop2、hadoop3的myid分别设置为2和3
