👉 Are you looking to change your Apache server port for better security and performance? Then this guide is for you!
Apache is the most popular web server application in the world, and it is widely used by web developers. It is an open-source software that is free to download and use. Apache server runs on port 80 by default, which is the standard HTTP port. However, changing the default Apache port can improve your server’s security and performance. This guide will provide you with all the necessary information to change the Apache port and further enhance your server’s functionality.
📢 Introduction
Apache is widely used in web applications to serve content and as a web proxy server. By default, Apache listens on port 80, which is the standard HTTP port. This is the port that most web browsers use for communicating with web servers. However, port 80 is a well-known port, and cybercriminals can exploit it to attack your server. Changing the default port can prevent such attacks from happening and provide better security for your server.
Moreover, changing the Apache port can also improve your server’s performance. It is because some Internet Service Providers (ISPs) provide limited bandwidth for port 80. By changing the port, you can bypass this limitation and ensure that your server runs smoothly without any bottlenecks.
In this guide, we will explain how to change the Apache port on Ubuntu, CentOS, and Windows operating systems. We will also discuss the advantages and disadvantages of changing the port and provide you with a table containing all the necessary information.
Step-by-Step Guide to Change Apache Port
Here’s a step-by-step guide to change the Apache port:
1. Backup Apache Configuration File
Before making any changes to the Apache configuration file, it is essential to back it up. The location of the Apache configuration file varies depending on the operating system:
Operating System |
Configuration File Location |
Ubuntu |
/etc/apache2/apache2.conf |
CentOS |
/etc/httpd/conf/httpd.conf |
Windows |
C:\Program Files (x86)\Apache Group\Apache2\conf\httpd.conf |
Backup the configuration file by executing the following command:
sudo cp /etc/apache2/apache2.conf /etc/apache2/apache2.conf.bak
Note: Replace the file path with the appropriate configuration file path for your operating system.
2. Open Apache Configuration File
Next, open the Apache configuration file using your preferred text editor. For example, to open the file on Ubuntu, execute the following command:
sudo nano /etc/apache2/apache2.conf
On CentOS, execute the following command:
sudo nano /etc/httpd/conf/httpd.conf
On Windows, navigate to the Apache installation directory and open the httpd.conf file using a text editor.
3. Find the Listen Directive
Locate the Listen directive in the Apache configuration file. The Listen directive is responsible for specifying the port on which Apache listens for incoming connections. By default, the Listen directive is set to port 80:
Listen 80
4. Change the Listen Directive
To change the port, replace the Listen 80 directive with your desired port number. For example, to change the port to 8080, enter the following:
Listen 8080
Save the configuration file and close the text editor.
5. Test the Configuration File
Before restarting the Apache server, it is crucial to test the configuration file for syntax errors. Execute the following command:
sudo apachectl configtest
If there are any syntax errors, the output will display an error message. Otherwise, the output will display a message stating “Syntax OK.”
6. Restart Apache Server
Finally, restart the Apache server to apply the changes. Execute the following command:
sudo service apache2 restart
Note: Replace apache2 with httpd on CentOS.
Advantages and Disadvantages of Changing Apache Port
Advantages
Here are some advantages of changing the Apache port:
1. Better Security
Changing the Apache port can improve your server’s security. Cybercriminals usually target well-known ports such as port 80 to launch attacks. By changing the port, you can prevent such attacks and secure your server.
2. Improved Performance
Some ISPs may limit the bandwidth for port 80. By changing the port, you can bypass this limitation and ensure that your server runs smoothly without any bottlenecks.
3. More Control
You have more control over your server by changing the default Apache port. It allows you to customize and optimize your server for your specific needs.
Disadvantages
Here are some disadvantages of changing the Apache port:
1. Potential Compatibility Issues
Changing the default Apache port may cause compatibility issues with some applications that rely on the default port. Therefore, it is essential to test the port change before implementing it on a live server.
2. Additional Configuration
Changing the Apache port requires additional configuration. You need to update the Apache configuration file, firewall rules, and application settings to reflect the port change.
3. Increased Complexity
Changing the Apache port adds complexity to your server setup. It requires additional management and maintenance, which may increase the workload for your IT team or yourself.

Frequently Asked Questions (FAQs)
Q1. Can I change the Apache port to any port number?
Yes, you can change the Apache port to any port number between 1024 and 65535.
Q2. How do I check the Apache version?
You can check the Apache version by executing the following command:
apachectl -v
Q3. How do I restart Apache on Ubuntu?
You can restart Apache on Ubuntu by executing the following command:
sudo service apache2 restart
Q4. How do I restart Apache on CentOS?
You can restart Apache on CentOS by executing the following command:
sudo systemctl restart httpd
Q5. How do I test the Apache configuration file for syntax errors?
You can test the Apache configuration file for syntax errors by executing the following command:
sudo apachectl configtest
Q6. How do I open the Apache configuration file?
You can open the Apache configuration file using a text editor. For example, on Ubuntu, execute the following command:
sudo nano /etc/apache2/apache2.conf
Q7. Can I change the Apache port without restarting the server?
No, you need to restart the Apache server to apply the changes to the port.
Q8. How do I update the firewall rules after changing the Apache port?
