I. network environment

Remarks:

Currently, it is a three node server, which allows one node to be damaged, the cluster state is normal, and normal services can be provided. For example, two nodes are damaged, only one node is left, and the entire zookeeper service is interrupted and cannot be connected.

2. View the status of the current server

[root@ops-site zookeeper]# ./bin/zkServer.sh status
JMX enabled by default
Using config: /app/zookeeper/bin/../conf/zoo.cfg
Mode: follower         #The current status is folwer

[root@nbutest zookeeper]# ifconfig

3. Connect to the zookeeper server (any one can be connected in the cluster state)

[root@nbutest zookeeper]# ./bin/zkCli.sh -server 10.3.151.34:2181      #Connection method
Connecting to 10.3.151.34:2181

IV. create a znode node

[zk: 10.3.151.34:2181(CONNECTED) 0] create /mingkang test   
Created /mingkang        #A / mingkang znode node was created

V. view the current status of all nodes

[zk: 10.3.151.34:2181(CONNECTED) 1] ls /          #See all
