1. Login to WHM
2. Search for the Software section on the navigation to your left
3. Click on "EasyApache (Apache Update)" in this section

4. Just follow the wizard to build the profile with all the custom configuration that you need for the server
5. Once you’re done, click on "Save and Build"

Sit back and relax since this might take a couple of hours to rebuild your server entirely.
Once done, you’ll get a success message along with the log file for this process. Once that is done, your server should be ready to use.
