How to change the Apache HTTP port number

The default apache HTTP Listen port number is 80. If you want to change this port, you need to edit the httpd.conf file.

If you have installed apache http server from source code, then the default installation path is/usr /local/apache2 or if you have installed it  using repository then the apache configuration file httpd.conf is located under /etc . ie /etc/httpd.conf

Open the httpd.conf file

vim /usr/local/apache2/conf/httpd.conf

Listen 80

Change the port number to your desired port number from 80

Listen <Your_port_number>  

For example  i here changed the port number from 80 to 8081

Listen 8081

Check your firewall settings and ensure that your desired port number is opened.

After changing the port number restart the apache server

You can restart it by using one of the following way

/usr/local/apache2/bin/apachectl -k restart

service httpd restart

/etc/init.d/httpd restart

service apache2 restart

/etc/init.d/apache2 restart

Now fireup your browser with http://localhost:8081 or http://127.0.0.1:8081
