What is OpenLiteSpeed?

OpenLiteSpeed ​​is the open-source version of LiteSpeed ​​WebServer Enterprise. It has all the necessary features found in LiteSpeed ​​WebServer including LScache.

This is the version for high-traffic websites. However, it does not integrate into any server administrator like DirectAdmin or cPanel.

The advantage of OpenLiteSpeed ​​is that it helps to reduce bandwidth usage, extremely fast technology, good support for external applications, SSL/Security Control support, etc.

What is Apache?

Apache (or Apache HTTP Server) is also open source web server software, developed and operated by the Apache Software Foundation. It can be said that Apache is one of the oldest web servers and is trusted by many users.

The advantage of Apache is that it is a stable free and open-source software. Apache also regularly updates security patches, the configuration is user-friendly, cross-platform, and has a large user community so it can support you at any time.

What is NGINX?

Similar to Apache, Nginx is also a famous and extremely popular open-source web server software. Although Nginx was originally used to serve HTTP web pages, it is now used as a reverse proxy, HTTP load balancer, and email proxy.

The advantage of Nginx is that it can handle more than 10,000 connections with low memory at the same time. In addition, you can use Cache to speed up Reverse Proxy, Apache also has flexible configuration and the ability to save query logs.

OpenLiteSpeed ​​– Apache – NGINX – which is the best web server?

This is a question many people ask when choosing to use these web servers. So between OpenLiteSpeed, Apache, NGINX, which webserver should you choose?

The answer to this question is not an easy one. There is no one-size-fits-all solution to choose Nginx over Apache or LiteSpeed ​​over Nginx. If you find yourself in a position where you might choose one over the other, you’ll really want to do your research and dig into how your users will use the sites running on the server and technology. that those sites are using, as that will help you come to a decision.

Apache is a great choice for Admins and Hosts who might want something very customizable as it has a rich collection of precompiled modules that can be added. These modules range from anything from authentication schemes to package-specific support for PHP, TCL, Python, Ruby, and more.

Apache is also reliable, stable, and considered beginner-friendly when setting it up for the first time. Because Apache is so widely used, it receives regular security and feature updates and has a large base to support.

Also, one important thing to remember – Apache runs applications that use CGI very well. For example, while Nginx technically supports CGI scripts, setting it up isn’t easy.

One feature of Apache that many criticize is its use of the .htaccess file to control things like rewrites and search engine indexing. Once these files are enabled, Apache must navigate the entire directory leading back to the parent directory and execute the commands listed in each of these .htaccess files. As you can imagine, this increases load times and consumes server resources.

On the other hand, Nginx can act as a reverse proxy in front of Apache or as its own web server, and there is no equivalent feature for .htaccess files. Applications written in Python and Ruby are known to be highly performant when running on the Nginx web server. With a load balancer, some optimizations, and Nginx, you can have a super performant setup. Nginx is also notoriously difficult to set up compared to contemporary Apache.

Please try to set up a test environment for the 3 web servers above.

As you all know about WordPress, caching is very important. So we have to make sure to use a suitable caching solution for each server in this test.

All of our tests were done with Keep-Alive enabled as well as pairing each server with a suitable cache option. And the result we got was that OpenLiteSpeed ​​outperformed NGINX and Apache in all tests.

SSL (Security Socket Layer) is a web protocol used to protect traffic to the server through encryption.

Typically, e-commerce or online financial services need this protocol because they often store sensitive information, like credit cards.

However, SSL certificates have now become a common standard for all websites, to protect user’s confidential data, like login information, social security numbers, ID cards, and more.

Fortunately, you can get a completely free and easy SSL certificate from the provider Let’s Encrypt, and we will guide you through installing SSL for Apache Webserver on a CentOS 7 server in this article.

How to install Let’s Encrypt SSL certificate for Apache on CentOS 7

You will need to reread how to access the Server’s SSH using Putty if you forgot.

Let’s Encrypt provides everyone with a completely free SSL certificate. Let’s see how to install it on Apache Webserver running CentOS 7 below.

Step 1: To get started you will need to update your system first with the following command

yum -y update

Step 2: Install mod_ssl to configure Let’s Encrypt

yum install -y mod_ssl

Step 3: Install EPEL repository and yum-utils

yum –y install epel-release yum-utils

Step 4: install Certbot for apache

yum –y install certbot-apache

Step 5: Install SSL

certbot

We need to go to the /etc/letsencrypt/live/{domain} directory to check the files containing the SSL key and certificate.

How to set up for automatic certificate renewal

By default, Let’s Encrypt is only valid for 90 days from the date of registration. So automatic certificate renewal is very important because if you forget it, the SSL certificate will expire. Therefore we need to set it to automatically renew when it is almost expired.

Step 1: Run the command below to check the renewal process manually

certbot renew –dry-run

This command will check for renewal of the current certificate if the certificate is less than 30 days from the expiration date.

Step 2: Adjust the cronjob to be able to run the auto-renew check command

acrontab -e

Add below line in cronjob

0 0 15 * * /usr/bin/certbot renew >/dev/null 2>&1

Thus, the above cronjob will automatically renew at 00:00 on the 15th of every month, you will not need to worry about forgetting to renew the certificate when it is almost expired.

Good luck!
