After making changes to the Apache configuration file, testing the configuration before implementing it is a good practice.
To test the Apache configuration file for errors, use the following command:
apachectl configtest
If the configuration file is fine, this command will return Syntax Ok. Otherwise, it will return detailed information about the error discovered.
If apachectl is not in your PATH and you do not know where it is, refer to the tech recipe Find a file by name to find the location of apachectl, then run it with the fully qualified path. Note the following example:
/usr/local/apache/bin/apachectl configtest
