解决方案：

/var/lib/rabbitmq/mnesia 目录下存在rabbit@localhost.pid、rabbit@localhost、rabbit@localhost-plugins-expand，删除这3项后，再使用systemctl start rabbitmq-server启动。

 

# 启动停止重启

service rabbitmq-server start

service rabbitmq-server stop

service rabbitmq-server restart

 

# 查看状态

rabbitmqctl cluster_status

rabbitmqctl status

 

新增一个用户

[root@sf106212 etc]# rabbitmqctl add_user admin admin@2015

查看当前用户列表

[root@sf106212 etc]# rabbitmqctl list_users

设置用户角色超级管理员(administrator)

[root@sf106212 etc]# rabbitmqctl set_user_tags admin administrator

设置用户权限

[root@sf106212 etc]# rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

查看指定用户的权限信息

[root@sf106212 etc]# rabbitmqctl  list_user_permissions admin

Listing permissions for user "admin" ...

/       .*      .*      .*

 

# 启动配置自动启动

rabbitmq-plugins enable rabbitmq_management

service rabbitmq-server start

chkconfig rabbitmq-server on
