rabbitmq服务重启操作实例
实际运维中需要对Rabbitmq集群业务进行业务重启操作，操作遵循的要求如下
关闭顺序：内存节点 => 磁盘节点
启动顺序：磁盘节点 => 内存节点
【检查rabbitmq集群运行状态】
[root@test1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@test1 ...
[{nodes,[{disc,[rabbit@test1]}, ------磁盘节点
{ram,[rabbit@test2,rabbit@test3]}]}, ----内存节点
{running_nodes,[rabbit@test2,rabbit@test3,
rabbit@test1]},
{cluster_name,<<"rabbit@test2">>},
{partitions,[]},
{alarms,[{rabbit@test2,[]},
{rabbit@test3,[]},
{rabbit@test1,[]}]}]【停止rabbitmq服务】
关闭顺序：内存节点 => 磁盘节点
[root@test3 ~]# systemctl status rabbitmq-server

[root@test1 ~]# 再次查询集群状态
[root@test1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@test1 ...
Error: unable to connect to node rabbit@test1: nodedown
DIAGNOSTICS
===========
attempted to contact: [rabbit@test1]
rabbit@test1:
* connected to epmd (port 18891) on test1
* epmd reports: node 'rabbit' not running at all
no other nodes on test1
* suggestion: start the node
current node details:
- node name: 'rabbitmq-cli-36@test1'
- home dir: /var/lib/rabbitmq【启动rabbitmq服务】
启动顺序：磁盘节点 => 内存节点先启动磁盘节点disk
