What is Apache?

Apache is one of the most commonly used web servers on the internet. It is a free and open-source software that is used to serve web pages and other web content to users. Apache is a highly customizable web server that can be configured to work with many web technologies such as PHP, Python, Perl, and more. Apache supports multiple platforms such as Windows, Linux, and macOS.

What is the default port number for Apache?

The default port number for Apache is 80 for HTTP and 443 for HTTPS. These port numbers are used to communicate between the server and clients. However, in certain situations, you might need to change the server port Apache to meet your specific needs.

Why do you need to change the server port Apache?

There could be several reasons why you might need to change the server port Apache, including:

• Port 80 and 443 might be blocked by your ISP or firewall
• You might have multiple web servers running on the same machine and need to differentiate them
• You might need to improve security by using a non-standard port number
• You might want to avoid common port numbers to protect against port scanning attacks

How to change server port Apache?

Changing the server port Apache requires you to make changes to the Apache configuration file, which is usually located in the /etc/apache2/ directory for Linux systems. Follow the steps below to change the server port Apache:

Step 1: Open the Apache configuration file

Listen 80

Step 3: Change the Listen directive

Change the Listen directive to the new port number that you want to use. For example, to change the port number to 8080, use:

Listen 8080

Step 4: Save and close the configuration file

Save the changes you made to the configuration file and close it.

Step 5: Restart Apache

Restart Apache to apply the changes. For example:

sudo systemctl restart apache2
