` ``1.下载解压zookeeper-3.4.6.tar.gz`

`    ``[root@hadoop001 software]# tar -xvf zookeeper-3.4.6.tar.gz`

`    ``[root@hadoop001 software]# mv zookeeper-3.4.6 zookeeper`

`    ``[root@hadoop001 software]#`

`    ``[root@hadoop001 software]# chown -R root:root zookeeper`

`    ``2.修改配置`

`    ``[root@hadoop001 software]# cd zookeeper/conf`
