openstack-nova-compute服务起不来

mq日志也有报错：

嗯。是的。收起

它说了呀，rabbitmq 用户名和密码不对收起

    早重启过了。没用的收起

425-fbaf-4bea-8dcc-9c8766f3f8d7 ] AMQP server 172.18.7.248:5672 closed the connection. Check login credentials: Socket closed

日志里有 Check login credentials关键字，mq，或者nova-compute有没有命令可以测试用户名，密码？收起

rabbitmq有没有命令可以测试到底是控制节点的nova.conf配置错误了，还是computer节点的nova.conf配置错误了收起

哦。openstack-nova-computer其实是active的，日志就是这个服务造成的。
        #systemctl status openstack-nova-compute

但是启动确实是报错了，虽然起完是active的。

在控制机器上看:
        mq服务是有启的。

        端口是开着的：
        #        netstat -antlp | grep 5672
        tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      33431/beam.smp

在计算节点上看：
        端口通的：
        #telnet xxx 5672
        Trying xxx...
        Connected to xxx.
        Escape character is '^]'.
        但是日志说连不到，这个日志不是启动openstack-nova-compute报的，而是自己不断刷出来的，systemctl stop libvirtd.service这个服务后来也关了，但是日志也一直在刷，不知道是什么服务要脸蛋控制节点的mq：

把libvirt重启一下，看看状态收起
