Introduction
Greetings, dear readers! In today’s digital world, where technology is advancing every second, web servers play an essential role in the delivery of webpages and applications. Apache web server is one of the most widely used web servers that provide a robust and flexible environment for hosting web applications.
By default, when you install the Apache web server, it assigns port number 80 to listen for incoming HTTP requests. However, in some cases, you may want to change the port due to security reasons or conflicts with other programs running on the same port. Fortunately, changing the port number in Apache web server is a straightforward process that can be done easily by following a few simple steps. In this article, we will guide you through the process of changing the port number in Apache web server.
What is Apache Server?
Apache is an open-source web server software developed by Apache Software Foundation. It is a cross-platform web server that runs on most operating systems such as Windows, Linux, and macOS. Apache web server is highly customizable, and it can be configured to support a wide range of web applications such as the popular content management system (CMS), WordPress.
Reasons for Changing Port in Apache Server
There are several reasons why you may want to change the port number in Apache web server:
🔹 Security: Changing the default port number 80 to a custom port number provides an additional layer of security to your web server. It makes it harder for hackers and malicious users to discover your open ports and exploit them.
🔹 Conflicts: In some cases, you may have other software running on your computer that uses port 80. This can cause a conflict with Apache server, preventing it from starting or functioning correctly. Changing the port number will help you resolve such conflicts.
🔹 Hosting Multiple Websites: If you are hosting multiple websites on a single server, changing the port number allows you to differentiate between different websites and route traffic to the correct website.
How to Change Port in Apache Server
The process of changing the port number in Apache web server involves the following steps:
Step |

Advantages of Changing Port in Apache Server
Below are some of the advantages of changing the port number in Apache web server:
🔹 Improved Security: By changing the default port number, you reduce the risk of your server being attacked by hackers or malicious users. It makes it harder for them to discover your open ports and exploit them.
🔹 Resolving Port Conflicts: Changing the port number allows you to resolve conflicts with other software running on your computer that uses the same port as Apache.
🔹 Hosting Multiple Websites: Changing the port number allows you to host multiple websites on a single server and differentiate between them.
Disadvantages of Changing Port in Apache Server
Although changing the port number in Apache web server has several advantages, it also has some disadvantages:
🔹 Hard-coded Port Numbers: If you use hard-coded port numbers in your web applications, you will have to modify them when you change the port number in Apache.
🔹 Port Number Management: Changing the port number in Apache requires you to manage multiple port numbers, which can be confusing if you are hosting multiple websites.
🔹 Access Restrictions: Changing the port number may also require additional configuration changes to allow access to the web server from firewalls or other security solutions.
