Improve WordPress Performance with Rocket-Nginx and Engintron for cPanel

The good performance of your website is one of the major concerns that you need to deal with, so your visitors can enjoy the content you present. Using WordPress, this can be achieved easily, due to the nature and flexibility of the application. There are multiple techniques for speeding up WordPress websites, using different server-side optimizations.

In most cases, our SSD WordPress Hosting will allow you to host your website and generate a lot of traffic withing even noticing. However, there are cases, when you will need your own hosting environment and resources dedicated to the needs of your website only. For example, if your website is generating millions of hits each month, this indicates that it is attracting a lot of attention and you can consider your own private VPS or Dedicated server. The resources on it will be allocated for the needs of your website only and you will not have to share them with other users.

However, the real beauty of private servers is the flexibility, you will be able to optimize the hosting environment for the needs of your WordPress website. There are multiple techniques that can allow you to host a WordPress website and have millions of hits, without affecting the actual performance of your website. Today, we will review the use of Engintron with WP-Rocket for best performance on cPanel servers.

What is Nginx and what is Engintron?

What is Nginx and what is Engintron

Nginx is an open source web server, designed to handle millions of hits on a website. It has a better performance than Apache, although both have their advantages and disadvantages. This is the reason why in a lot of cases, Nginx is used as a reverse caching proxy in front of the Apache service, which results in a significantly improved performance.

Engintron is integrating Nginx on cPanel servers easily and provides a graphical interface that will allow you to easily configure it on your cPanel server via WHM. The installation is easy and quite straightforward so you can take care of that within minutes.

What is WP Rocket?

What is WP Rocket

WP Rocket is a popular cache and performance plugin for WordPress websites. It offers a lot of features that will significantly improve the performance of your website, without affecting it in any other way.

The setup of WP Rocket is as easy as any other plugin for WordPress. However, unlike other caching plugins, the installation of WP Rocket goes through without any issues, it does not require much extensive configuration and you will notice results as soon as you enable it on your website. This is an excellent way to get the performance you need for your project!

As an official WP Rocket partner, FastComet offers 20% discount on the plugin for all existing clients. You can get that via your Client Area.

Integrate Engintron with WP Rocket

If both of the products are so good, why not integrate them together, right? This is something that we have been thinking for quite some time now and there is a solution to it as well!

1. Install WP Rocket

The first thing you need to consider is the installation of WP Rocket on your website. We have an excellent set of tutorials on how to achieve that easily, as well as detailed information on how to configure the plugin. Still, if you experience any difficulties with the installation, you can always request that from our 24/7 Technical Support team.

2. Install Engintron

The second step is to install Engintron. To handle the process, you need root access to your server and pre-installed Git. The steps below are tested on CentOS 6 with cPanel 11.48, but it should work without any issues on other cPanel versions.

Log into your server as root and execute the following commands:

wget sh install

The installation will take a couple of minutes for full completion. In the end, you will receive a successful message to inform you that the process is completed. When done, simply access your WHM panel > Plugins > Engintron for WHM.

NOTE: Each time when you add, modify or delete a domain from your server via WHM, you will have to rebuild te virtual hosts on your server. This can be completed easily via WHM > Plugins > Engintron for WHM > Sync NginX with Apache vhosts.

3. Integrate Rocket-Nginx

The third step is to implement the Nginx configuration for WP Rocket. You will have to do this step for each website that you wish to configure with it. Simply execute the following commands:

cd /etc/nginx git clone cd conf.d

Now, you simply need to open the vHost for the domain that you wish to enable the WP Rocket Nginx configuration and add the following line:

server { ... # Rocket-Nginx configuration / add line below only include rocket-nginx/rocket-nginx.conf; ... }

Save the file and reload the NginX service:

nginx -s reload


We are always looking for better performance and there are multiple ways of achieving that. With the use of Engintron and the WP Rocket Nginx configuration, you can easily achieve that on cPanel servers. We still suggest reviewing the official documentation for Engintron and Rocket-Nginx for a better understanding of how this works.
