Resolved: apache2ctl configtest failed

The Apache server’s configuration, is named httpd.conf, contains a set of directives that defines the behavior of the server. These directives include key details like the server’s IP address and port number, the document root directory, the modules to load, and the access control rules.

Each time we make changes to the Apache configuration file, the syntax has to be accurate./ Else the server will fail or start behaving unexpectedly.

Hence, our experts suggest checking the syntax of the configuration files each time we make a modification. This can be easily done with the apache2ctl configtest command. This command will read the configuration file, checks it for errors, and then report any problems it finds.

However, sometimes the apache2ctl configtest can fail with the following message:

~# /etc/init.d/apache2 restart * Restarting web server apache2 [fail] * The apache2 configtest failed. Output of config test was: Segmentation fault (core dumped) Action ‘configtest’ failed. The Apache error log may have more information.

This is often due to a conflict between the modules installed earlier and the ones installed recently. We can easily resolve the issue by taking a closer look at the modules with the following command: cd /etc/apache2/mods-enabled If the output of the command displays more than one module as enabled, we can disable either one to resolve the issue.

After resolving the apache2ctl configtest failed error, we can run the command once more to check for syntax errors in the Apache configuration files. Let us know if you need further help with the apache2ctl configtest failed error.
