Apache2 Not Running

I'm running an Apache2 LAMP server with Ubuntu 18.04 and suddenly without a warning, the Apache stops running. I tried figuring out the problem with sudo service apache2 status and it shows the following:

sudo service apache2 status
● apache2.service - The Apache HTTP Server
   Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)

Sep 03 13:07:40 localhost systemd[1]: Failed to start The Apache HTTP Server.

The first thing I do is try to start it manually with sudo apachectl restart which results in the following:

sudo apachectl restart
httpd not running, trying to start
Action 'restart' failed.
The Apache error log may have more information.

So I check the log with sudo view /var/log/apache2/error.log and it shows a very long list as below:

I have tried to phpdismod the three error modules and it didn't work. I am running PHP 7.2 and php7.0-fpm, for SSL I have Let's Encrypt Certbot installed.

Can someone out there please tell me what's going on?

Solution

  • Found the problem, a corrupted code in my apache config file.

    For those who have the same problem here's how to fix it:

    1. Go to Apache2 sites-available directory using cd /etc/apache2/sites-available
    2. Disable ALL config files using sudo a2dissite example.com.conf example-2.com.conf ... (Ignore the systemctl reload apache2 now, we will get to it later)
    3. Enable the default config files using sudo a2ensite 000-default.conf
    4. Reload Apache2 with sudo systemctl reload apache2
    5. Enable the config files one by one to find out which one is corrupted using sudo a2ensite test-1.conf and reload apache using sudo systemctl reload apache2 and finally test if it is working with sudo service apache2 status
    6. Once you found the file edit it, fix the problem and off to enable all the config files! Be sure to disable the default using sudo a2dissite 000-default.conf, check the Apache is running with sudo service apache2 status.

    There you have it! That's how I fix it anyway. Oh, the disabling and enabling config files might result in pointing to the wrong directory, when you enabled all of them back it should return to normal.

    Have a great day :D
