This guide helps website administrators set up a 301 redirect, ensuring visitors who type in the non-www version of the domain are automatically redirected to the www version, providing a uniform experience across all URLs.

 

Prerequisite

  • SSH access to server
  • Access to your website’s root directory
  • Ability to edit the .htaccess file
  • Basic understanding of Apache web server configurations.

 

Step-by-step guide

Step 1: Access to your server

  • Access your server via SSH. If you are non-having control panel like DirectAdmin or cPanel, you may continue Step 2 once connected.
    Else, if you are having control panel, you will need to switch to your control panel user before continuing on Step 2.

    sudo su <user>

Step 2: Locate and navigate to website root directory

  • Locate your website root directory and navigate to the directory by using cd command.
    For the server which not having control panel, the path typically will be as below:

    cd /var/www/html

    For the server which having control panel, the path typically will be as below:

    cd /home/<username>/<domain>/public_html/

Step 3: Verify if .htaccess existed

  • Once you have reached the website root directory, you will need to verify if the .htaccess file existed.
    The.htaccess file is a hidden file, you may use command below to show it.

    ls -la | grep "htaccess"
  • If the .htaccess does not exist, you may run the command below to create
    touch .htaccess
    chmod 644 .htaccess

Step 4: Edit the .htaccess file to redirect the site

  • To edit the .htaccess file, we will be using vi command as below.
    vi .htaccess
  • Once you have entered editor screen, press i to enable the edit mode and adding lines as below.
    RewriteEngine On 
    RewriteCond %{HTTP_HOST} !^www\.domain\.com [NC] 
    RewriteRule (.*) http://www.domain.com/$1 [L,R=301]

    or

    RewriteEngine On 
    RewriteCond %{HTTP_HOST} !^www\. [NC] 
    RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
  • Then press ESC and enter :wq to save.
    :wp
  • The domain.com should be redirected to www.domain.com
