    You're probably going to need to add more details. What changed? What led you to run the "systemctl restart httpd.service" command in the first place? Were you changing Apache configs? Did the server crash on it's own? or

    If you changed server configs, change them back and try to restart it

    If the server crashed on it's own. Look at /var/log/syslog (that's where it is in Ubuntu) and look for any errors that may have caused the crash.

    Ultimately, it's extremely hard to debug without WAY more info :)

    Hello,

    Check to make sure that you are not having disk issues. Can you write to the disk?

    Regards,
    Chris

    This is something wrong you config file. how you configure this service ? auto script installation or manually configured service.Check service status and error log.

    update to EasyApache4 wherein after the update was installed Apache service is not working or failing to restart properly.

    following commands didn't solve the issue

    yum clean all
    yum -y update

    /usr/local/cpanel/bin/rebuild_phpconf --current

    /usr/local/cpanel/bin/rebuild_phpconf --ea-php55=cgi --ea-php56=suphp

    If you updated Apache, you need to do a Google search and find the Apache 4 default Apache config. Switch that out with your current config. And update all your sites-available with the new versions of their configs and you'll be good to go. If none of that made sense to you, you've got a long journey ahead of you as far as server administration goes. I'm great at it but I rarely waste my time doing it because it's such a black hole of time unless you're doing it at scale.
