Zookeeper 02 zkCli

可以通过zkCli 启动客户端，连接Zookeeper服务器：

bin/zkCli.sh

接下来执行几个简单命令

[zk: localhost:2181(CONNECTED) 0] ls / 
[NameService, configure, zookeeper]

[zk: localhost:2181(CONNECTED) 4] ls /NameService
[Server-A]

[zk: localhost:2181(CONNECTED) 1] create /workers ""
Created /workers

[zk: localhost:2181(CONNECTED) 4]  create -e /master "master1.example.com:2223"     // -e 创建  ephemeral znode
Created /master

[zk: localhost:2181(CONNECTED) 2] stat -w /master    //添加watch

[zk: localhost:2181(CONNECTED) 5] ls -w /workers     //添加对子节点的watch

[zk: localhost:2181(CONNECTED) 5] delete /workers
[zk: localhost:2181(CONNECTED) 6] ls /
[NameService, configure, zookeeper]

[zk: localhost:2181(CONNECTED) 3] stat /zookeeper
