报错--Job for rabbitmq-server.service failed

报错

[root@ct ~]# systemctl start rabbitmq-server
Job for rabbitmq-server.service failed because the control process exited with error code. See “systemctl status rabbitmq-server.service” and “journalctl -xe” for details.

解决

先杀死进程

ps -ef | grep rabbitmq       #查询进程号
ps -ef | grep rabbitmq | grep -v grep | awk '{print $2}' | xargs kill -9   #杀死进程
rabbitmq-server -detached    #启动
rabbitmqctl status           #查看状态

再创建就可以了
创建消息队列用户，用于controler和node节点连接rabbitmq的认证

[root@ct ~]#  rabbitmqctl add_user openstack RABBIT_PASS
Creating user "openstack"
