事发缘由：因三级等保、需要将centos7系统中的”高危”用户进行封禁或者注释，用户有：
dademon、adm、lp、shutdown、halt、mail、operator、games
ftp、nobody、system-network、polkitd、dbus、postfix，其中polktd、dbus注释后重启机子直接导致机子启动不来，进入单用户取消注释方可正常启动。
后遗症来了：正常启动后 ，登录非常慢，连服务器正常启动都不行，直接报错：
Authorization not available. Check if polkit service is running or see debug message for more information.
Failed to restart systemd-logind.service: Connection timed out
意思就是请检查polkit这个服务是否运行，当我去检查的时候polkit这个服务已经处于不运行的状态了。可是当我去使用
systemctl start polkit 去启动服务时候直接报错：Failed to get properties: Failed to activate service ‘org.freedesktop.systemd1‘: timed out
查询message日志 dbus一直在报错：

百度查资料：/usr/lib/polkit-1/polkitd --no-debug
打开一个小窗口服务能正常进行启动已经关闭。但是启动polkit 服务时候处于无效状态。目前只能解决到这里……尽力了……
记录一次polkitd的报错（只解决了其他服务能正常使用systemctl）
