In this article, AZDIGI will show you how to quickly upgrade Apache on Centos Web Panel with just a few simple steps without using complex command lines. So please continue to read the article.

I. Overview

Apache is a free and open source Web Server software that accounts for about 46% of the worldwide website market share. The official name of Apache is Apache HTTP Server, operated and developed by the Apache Software Foundation. Apache is one of the oldest and most trusted web servers, the first version was released more than 20 years ago, in 1995.

Although Apache is called a web server, it is not a physical server. It is a piece of software that runs on that server. Its job is to establish a connection between the server and the user’s browser (Firefox, Google Chrome, Safari…). Then transfer files back and forth between them (two-way client-server architecture). Apache is a cross-platform software that works well with Unix and Windows servers.

How Apache works

When a visitor loads a web page on your website, for example, you go to the browser and type in the name of a certain website, the user browser will send a request to upload that website to the server and Apache will return the result with all the files that make up the website (images, text, etc). The server and client communicate via the HTTP protocol, and Apache is responsible for ensuring this process goes smoothly and securely between the client and server.

II. Implementation guide

To upgrade/downgrade the Apache version, follow these 3 steps:

Step 1: Check the current Apache version

With CWP, you can check quickly by going to the homepage interface => find the Application Version section as shown, the screen will show the services running on the VPS and the version of that service.
