What is Apache Server Port?
Apache Server Port is a number that identifies a specific endpoint of a connection in computer networking. In the case of Apache HTTP Server, it is the TCP port number that Apache listens to for incoming client requests. By default, Apache Server Port is set to 80 for HTTP and 443 for HTTPS connections. However, this default port number can be changed to any available port number for security and customization purposes.

The Advantages of Changing Default Apache Server Port
Changing the default Apache Server Port has several advantages, including:
Enhanced Security
By changing the default Apache Server Port, you can prevent unauthorized access to your server. Hackers often scan for open ports, and changing the default port number makes it harder for them to launch attacks.
Customization
Changing the default Apache Server Port allows you to customize your server configuration according to your specific needs. For example, if you’re running multiple servers on the same machine, you can assign a unique port number to each server to avoid conflicts.
Performance Enhancement
Changing the default Apache Server Port can help improve server performance by reducing network congestion. By using a less popular port number, you can avoid clashes with other services and reduce the risk of server crashes.
The Disadvantages of Changing Default Apache Server Port
Despite the advantages of changing the default Apache Server Port, there are also some disadvantages that you should consider:
Inconvenience
Changing the default Apache Server Port can be inconvenient for users who are accustomed to the standard port numbers. If you change the port number, users must remember to include the new port number in their URLs or bookmarks.
Difficulty in Troubleshooting
Changing the default Apache Server Port can make troubleshooting more difficult. If there’s an issue with the server, users may not know the correct port number to use when contacting support.
Compatibility Issues
Changing the default Apache Server Port can cause compatibility issues with some applications that rely on the standard port numbers. For example, some firewalls and load balancers may not work properly if the port numbers are changed.
