# 模拟网络分区
# 1. 让 node2 脱离集群
在 node2执行命令，关闭网卡。
ifdown ens3
# 2. 查看各节点状态
等待一分钟左右，在 node1查看集群状态，执行rabbitmqctl cluster_status，此时node1认为node2已经脱离集群。node3情况一样。
[root@node1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@node1 ...
Basics
Cluster name: rabbit@node1
Disk Nodes

Running Nodes

Maintenance status
Node: rabbit@node1, status: not under maintenance
Node: rabbit@node3, status: not under maintenance
Network Partitions
(none)
在node2上执行rabbitmqctl cluster_status，显示信息，此时还没有出现网络分区。
# 3. 让 node2 恢复
node2恢复网卡。
ifup ens3
# 4. 查看各节点状态
查看 node1集群状态，检测到网络分区。node3情况一样。
