Our previous article in this series focused on defining and fitting MPM to match your environment. Building off of our last tutorial we will be discussing specific details on how to adjust the previously mentioned Apache configuration directives on the various types of Liquid Web servers.
- Core-managed CentOS 6/7 Servers
- Core-managed Ubuntu 14.04/16.04 LTS Servers
- Fully-managed CentOS 6/7 cPanel Servers
- Fully-managed CentOS 7 Plesk Onyx 17 Linux Servers
Core-managed CentOS 6/7 Servers
On CentOS servers, Apache configuration files are located in /etc/httpd/.
- Log in to the server over SSH or FTP.
- First, create an optimization file. It’s necessary for the optimization file to be loaded last so that it will override all other previous settings. We suggest naming the file z-optimize.conf.
touch /etc/httpd/conf.d/z-optimize.conf - Open file for editing with your favorite editor:
vim /etc/httpd/conf.d/z-optimize.conf - Input necessary directive change, using IfModule statements for compatibility.
- Save the file.
- Reload Apache.
service httpd restart
Core-managed Ubuntu 14.04/16.04 LTS Servers
On Ubuntu servers, Apache configuration files are located in /etc/apache2/.
- Backup existing apache2.conf file:
cp -p /etc/apache2/apache2.conf{,.bak.$(date +%F_%H%M%S)}
ls -lah /etc/apache2/apache2.conf* - Open file for editing with your favorite editor:
vim /etc/apache2/apache2.conf - Append the necessary directive changes to the very bottom of the config file.
- Save the file.
- Reload Apache.
apache2ctl reload
Fully-managed CentOS 6/7 cPanel Servers
Out of the box, our Fully-Managed cPanel servers come with general optimization suitable for most small and mid-range sites. cPanel servers use a sophisticated template system for managing Apache configurations. cPanel typically handles all configurations seamlessly by using the WHM and cPanel interfaces. However, it is still quite simple to set up an optimization configuration file. You have the choice to compose an optimized configuration file via command line over SSH/FTP or within the WHM interface.
Command Line Method (SSH/FTP)
The Apache configuration files on cPanel servers are stored in: /usr/local/apache/conf/includes/
You can use several included files for optimization. It’s necessary for the optimization file to be loaded last so that it will override all other previous settings. For this reason, the post_ include files work best, specifically the post_virtualhost_global.conf file.
- Log in to the server with SSH or FTP.
- Open the post_virtualhost_global.conf file in your favorite editor. (This file is typically empty and maybe missing entirely. This is okay and not unexpected.)
vim /usr/local/apache/conf/includes/post_virtualhost_global.conf - Input necessary directive change, using IfModule statements for compatibility.
- Save the file.
- Reload Apache.
/scripts/restartsrv_apache - Reload Apache PHP FPM servers.
/scripts/restartsrv_apache_php_fpm
WMH Method
- Log in to Webhost Manager (WHM) on the necessary server.
- Type apache in the quick find box.
- Click on Apache Configuration in the Service Configuration section.
- Click on Include Editor.
- Scroll down to Post VirtualHost Include.
- Select All Versions from the drop down.
- In the box input the necessary directives for optimization.
- Click the Update button when finished to save the change.
- On the left-hand navigation pane in the Restart Services section at the bottom click on HTTP Server(Apache).
- Click on the Yes button.
- Back to the left-hand navigation pane in the Restart Services section at the bottom click on PHP-FPM services for Apache.
- Click on the Yes button to complete the configuration.
Fully-managed CentOS 7 Plesk Onyx 17 Linux Servers
Out of the box, our Fully-Managed Linux Plesk servers come with general optimization suitable for most small and mid-range sites. Plesk uses mostly a standard CentOS based Apache2 installation so that it can be modified in the same manner as our Core-managed CentOS 6/7 servers:
On CentOS servers, Apache configuration files are located in /etc/httpd/.
- Log in to the server over SSH or FTP.
- First, create an optimization file. It’s necessary for the optimization file to be loaded last so that it will override all other previous settings. Suggested name: z-optimize.conf.
touch /etc/httpd/conf.d/z-optimize.conf - Open file for editing with your favorite editor:
vim /etc/httpd/conf.d/z-optimize.conf - Input necessary directive change, using IfModule statements for compatibility.
- Save the file.
- Reload Apache.
service httpd restart
