server 1:

[root@wx03 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /zookeeper/server1/bin/../conf/zoo.cfg

server 2:

[root@wx03 bin]# ./zkServer.sh  status

server 3:

[root@wx03 bin]# ./zkServer.sh  status

在server 3上创建节点；

ls /
[scan01, zk, mysql, zk01, zookeeper]
[zk: localhost:2181(CONNECTED) 1] create czcb001 'ddadqweq312'
Command failed: java.lang.IllegalArgumentException: Path must start with / character
[zk: localhost:2181(CONNECTED) 2] create /czcb001 'ddadqweq312'
Created /czcb001
[zk: localhost:2181(CONNECTED) 3] ls /
[scan01, zk, mysql, zk01, czcb001, zookeeper]
[zk: localhost:2181(CONNECTED) 4] 

server 1节点；

ls /
[scan01, zk, mysql, zk01, zookeeper]
[zk: localhost:2181(CONNECTED) 1] ls /
[scan01, zk, mysql, zk01, czcb001, zookeeper]
[zk: localhost:2181(CONNECTED) 2] 

server 2节点：

ls /
[scan01, zk, mysql, zk01, zookeeper]
[zk: localhost:2181(CONNECTED) 1] ls /
[scan01, zk, mysql, zk01, czcb001, zookeeper]
