Cannot start services on CentOS 7

  • 772

Suddenly, I cannot start services on my VPS(CentOS 7). For example,

service httpd start
Redirecting to /bin/systemctl start  httpd.service
Authorization not available. Check if polkit service is running or see debug message for more information.
Failed to start httpd.service: Connection timed out
See system logs and 'systemctl status httpd.service' for details.

This is probably because the domain name I used as the host name has expired. I do not know the logic behind the service command. I start httpd, why does it invoke polkit service? The polkit service is also dead and cannot be started. The "service polkit status -l" command shows a message:

Lost the name org.freedesktop.PolcyKit1 - exiting

How to solve the problem?

service centos7 systemctl

    You need to use sudo

    [user@localhost ~]$ sudo systemctl start httpd

    or login as root

    [root@localhost ~]# systemctl start httpd

    in order to start and stop services.
