操作Zookeeper（启动与停止、查看进程与状态、启动退出客户端）

1、启动Zookeeper：./zkServer.sh start

[app@laizhenghua bin]$ pwd
/home/app/zookeeper-3.4.12/bin
[app@laizhenghua bin]$ ./zkServer.sh start

2、查看Zookeeper进程是否启动：jps

[app@laizhenghua zookeeper-3.4.12]$ jps
48256 Bootstrap
14369 Bootstrap
61731 Bootstrap
13606 Jps
1111 Bootstrap
12344 Bootstrap
13564 -- main class information unavailable

# 出现以上输出表示启动正常

3、查看Zookeeper状态：./zkServer.sh status

[app@laizhenghua bin]$ pwd
/home/app/zookeeper-3.4.12/bin
[app@laizhenghua bin]$ ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/app/zookeeper-3.4.12/bin/../conf/zoo.cfg
Mode: standalone

4、启动客户端：./zkCli.sh

[app@laizhenghua bin]$ pwd
/home/app/zookeeper-3.4.12/bin
[app@laizhenghua bin]$ ./zkCli.sh
Connecting to localhost:2181
...

# 如果 zoo.cfg 文件下的 clientPort 配置项修改过 如 clientPort=2583 则启动方式为
[app@laizhenghua bin]$ ./zkCli.sh -server localhost:2583
Connecting to localhost:2583
 ...

5、退出客户端：直接Ctrl + c或quit

quit

6、停止Zookeeper：./zkServer.sh stop

[app@laizhenghua bin]$ pwd
/home/app/zookeeper-3.4.12/bin
[app@laizhenghua bin]$ ./zkServer.sh stop
