Centos 使用Systemctl报Error getting authority

Centos 使用Systemctl报Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Timeout was reached (g-io-error-quark, 24)
在使用centos7.4 安装服务的时候报错：

Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Timeout was reached (g-io-error-quark, 24)

解决：

ps -ef |grep polkit

再安装：

pyum reinstall polkit

再重启,就可以解决

reboot
