Change Apache Web Server Port: A Comprehensive Guide

Introduction

Welcome to our guide on changing the Apache web server port. Apache is one of the most widely used web servers in the world, thanks to its ease of use, reliability, and open-source nature. However, out of the box, the Apache web server runs on port 80, which can cause conflicts with other applications or services on the same server. In this article, we will provide a detailed explanation of how to change the Apache web server port, including its advantages, disadvantages, and FAQs, to help you better understand this process.

What is Apache?

Apache is a free and open-source web server software that powers more than 40% of active websites worldwide. It is highly customizable and platform-independent, making it easy to use on Windows, macOS, Linux, and other operating systems. Apache is known for its security, stability, and performance, and it supports a wide range of modules and extensions for building dynamic websites and web applications.

Why Change Apache Web Server Port?

The default port for Apache web server is 80, which is the standard port used for HTTP traffic. While this is fine for most scenarios, there are several reasons why you might want to change the Apache web server port:

  1. Port conflicts: If you are running multiple web servers or applications on the same server, there could be conflicts when different services try to use the same port. Changing the Apache web server port can help avoid these conflicts and ensure that each service gets its own dedicated port.

  2. Security: Changing the Apache web server port can make it harder for attackers to find and exploit vulnerabilities in your web server. Since most attackers scan for web servers on the default port, moving to a non-standard port can reduce your exposure to attacks.

  3. Compliance: Some organizations or regulations require that web servers run on non-standard ports as an additional security measure. By changing the Apache web server port, you can meet these requirements and maintain compliance.

How to Change Apache Web Server Port

To change the Apache web server port, you will need to edit the main Apache configuration file, which is usually located at /etc/apache2/apache2.conf or /etc/httpd/conf/httpd.conf, depending on your operating system. Follow these steps:

Step
Description
1
Open the Apache configuration file in a text editor.
2
Search for the line that says “Listen 80” or “Port 80”. This tells Apache to listen on port 80.
3
Change the port number to your desired port, such as “Listen 8080” or “Port 8080”. Make sure the port is not already in use by another application or service.
4
Save the file and exit the text editor.
5
Restart the Apache web server to apply the changes, using the command “sudo service apache2 restart” or “sudo systemctl restart httpd” on Linux, or by using the Apache Web Server Manager on Windows.

How to Test Apache Web Server Port

After changing the Apache web server port, you should test to ensure that the server is running on the new port and that you can access it from a web browser. Follow these steps:

  1. Linux: Open a web browser and enter “http://127.0.0.1:newport” (replace newport with the new port number) in the address bar. If the Apache web server is running on the new port, you should see the default Apache page.

  2. Windows: Open the Apache Web Server Manager and check the “Server Name” and “Port” fields on the main page. If the port number has been changed, it should be reflected here. You can also test by opening a web browser and entering “http://localhost:newport” in the address bar.

Advantages and Disadvantages of Changing Apache Web Server Port

Advantages

There are several advantages to changing the Apache web server port:

  1. Reduced port conflicts: By changing the Apache web server port, you can avoid conflicts with other services or applications that might be using the default port.

  2. Enhanced security: Changing the Apache web server port can make it harder for attackers to find and exploit your web server. Most attackers scan for web servers on the default port, so moving to a non-standard port can reduce your exposure to attacks.

  3. Compliance: Some regulations or best practices require that web servers run on non-standard ports as an additional security measure. By changing the Apache web server port, you can meet these requirements and maintain compliance.

Disadvantages

However, there are some disadvantages to changing the Apache web server port:

  1. Inconvenience: Changing the Apache web server port can cause inconvenience for users who are used to accessing your website on the default port. You may need to provide instructions on how to access your website on the new port.

  2. Incompatibility: Some web applications or services may be hard-coded to use the default port, and changing the port could cause these applications to break or become incompatible. Make sure to test your applications thoroughly after changing the Apache web server port.

  3. False sense of security: While changing the Apache web server port can make it harder for attackers to find your web server, it does not provide 100% protection against attacks. Attackers can still scan for open ports and use other methods to identify your web server.
