Hello, @rajviswas

Have you checked the Apache configuration for any syntax errors? You can do this using the following command:

apache2ctl configtest

You can also check the journal log as that will give you a better idea about what happened:

sudo journalctl -xe

You can check the Apache error log as well. The location of the log file should be:

/var/log/apache2/error.log and you can simply tail the log using:

tail -f /var/log/apache2/error.log

or tail the last 100 entries of it:

tail -n 100 /var/log/apache2/error.log

Let me know how it goes.

Hi @rajviswas,

Before we can provide you with the way to solve it, we’ll need to know what the exact error is. There are a couple of ways to go about getting the exact error.

One is to try and start Apache and when it fails to check your Apache Error_log. The default installation for Apache2 on Ubuntu creates a log subdirectory: /var/log/apache2. Within this subdirectory are two log files with two distinct purposes: /var/log/apache2/access. log - records of every page served and every file loaded by the web server. The second file is the error_log providing every error generated by Apache. You can get yours there.

The second way would be again to try and restart Apache and when it fails, to run the command

journalctl -xe

It will again provide you with the experienced error.

As soon as you do, you can post it here for more information
