How to change the port number of Apache Web Server?

Default port to access the Apache is 80. Secure port for communicating with world for Apache is 443. Very frequently, we need to update the Apache port. Here is procedure to update the Apache port number on Linux server.

Steps -

/etc/httpd/conf/httpd.conf

You can use any file editor with which you are comfortable to update the file  -

vi /etc/httpd/conf/httpd.conf

3. Search for the listen value in Apache configuration file. You can use blow command to find it -
grep Listen /etc/httpd/conf/httpd.conf

Output will be as follow -
Listen 0.0.0.0:80  ---------------> This for non SSL port
Listen [::]:80

Listen 0.0.0.0:443----------------> This is for SSL port
Listen [::]:443
