How to redirect a domain to WWW using Apache virtual host Ubuntu


Apache webserver server the website over the internet. For the individual website the it create it’s virtual host using apache and redirect user to the specific directory. We can handle n number of website on a single server as long as server and handle the load. 


Apache web server should be installed, domain names configured through virtual hosts that specify the ServerName with the SSL certificates for the domain.

Virtual Host Redirect to WWW

Step1: Open the file to edit.

sudo nano /etc/apache2/sites-available/

Step 2: To redirect all the traffic to add the following code. This redirects not only the HTTP traffic to HTTPS but also the traffic to with HTTPS.

RewriteEngine on
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www. [NC]
RewriteRule ^ http%{ENV:protossl}://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

The complete configuration file looks like:

DocumentRoot /var/www/html/example_zehncloudcom
Redirect permanent /

        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        ServerAdmin webmaster@localhost
	DocumentRoot /var/www/html/example_zehncloudcom
        RewriteEngine on
        RewriteCond %{HTTP_HOST} .
        RewriteCond %{HTTP_HOST} !^www. [NC]
        RewriteRule ^ http%{ENV:protossl}://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
