一、准备工作
zookeeper的安装需要依赖于jdk，所以这里事先需要安装好jdk，并且配置好jdk的环境变量
二、安装
1. 从zookeeper官网下载zookeeper安装包 apache-zookeeper-3.5.5-bin.tar.gz
2. 使用ftp根据将安装包上传到CentOS并且解压
3. 将解压后的安装包目录中的conf下的zoo_sample.cfg文件复制一份，改名为zoo.cfg.

[root@localhost conf]#
4. 启动zookeeper
[root@localhost apache-zookeeper-3.5.5-bin]# pwd
/opt/apache-zookeeper-3.5.5-bin
[root@localhost apache-zookeeper-3.5.5-bin]# sh bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/apache-zookeeper-3.5.5-bin/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[root@localhost apache-zookeeper-3.5.5-bin]#
5. 查看zookeeper的状态
[root@localhost apache-zookeeper-3.5.5-bin]# sh bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/apache-zookeeper-3.5.5-bin/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost.
Mode: standalone
[root@localhost apache-zookeeper-3.5.5-bin]#
6. 使用客户端连接zookeeper
[root@localhost apache-zookeeper-3.5.5-bin]# sh bin/zkCli.sh
