配置openstack环境的rabbitmq时遇到报错：Error: unable to connect to node rabbit@localhost: nodedown

解决方式：
1.检查之前安装的软件环境是否安装成功
2.重新安装完成软件环境，要先杀死rabbitmq的所有进程

ps -ef | grep rabbitmq 查询mq的进程

ps -ef | grep rabbitmq | grep -v grep | awk '{print $2}' | xargs kill -9 将mq的进程杀掉

rabbitmq-server -detached 启动mq

rabbitmqctl add_user openstack RABBIT_PASS
