CentOS使用systemctl daemon-reload报错Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: Timeout was reached (g-io-error-quark, 24)解决办法

　　CentOS修改了系统启动文件后需要重载报错

systemctl daemon-reload

　　

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

　　解决办法安装polkit

yum -y install polkit

　　再重载即可
