Many companies utilize the well-known open-source web server Apache2 to host websites and applications. You might experience a problem where the service cannot be started and you see an error message like "Unable to start service apache2: Job for apache2.service failed because the control process exited with error code".

Manually starting Apache2 service also failed
In this article, we will guide you through the troubleshooting steps to fix this issue.
1. Check any port conflicts
Conflicting ports can also prevent the Apache2 service from starting and it is one of the most common issue
To find processes utilizing the same port as Apache2, use the
netstat -tlnp | grep ":80" command.
If there is a conflict, you may either terminate the infringing service or modify the configuration files to alter the port that Apache2 uses.
Here is the screenshot where I am checking if there is any process which has already occupied the port 80 -
- Kill the process running on the port using the command
kill -9 <process-id>
- Update the apache config located
/etc/apache2/apache2.confand assign different port for the apache2 service.
2. Check the Apache2 Error Log

apachectl configtest command. The configuration files can be edited to correct any issues.
apache2.conf is correct then you should see following message -
4. Start the Server again
Starting-service problems can occasionally be resolved by simply restarting the server.
Here is the command to restart the apache2 service -

You may uninstall the program with the command -
1sudo apt-get remove apache2
After remove the apache2 you can reinstall it with the command -
1sudo apt-get install apache2
Although setting up and operating Apache2 might be simple, problems can arise if the service doesn't start.
