I recently needed to create a subDomain for one of my websites. This subdomain points to a separate WordPress installation that is linked to from the parent domain. Here’s a quick overview of how to do this.
The directory structure on my server is similar to the following:
Start by navigating to the
/etc/apache2/sites-available directory, then create a configuration file for the new subDomain using a command structured as follows – just switch ‘example’ and ‘blog’ with your target domain and subDomain names:
$ sudo cp 000-default blog.example.com.conf
open blog.example.com.conf in an editor and make the following changes:
ServerName blog.example.com ServerAdmin <your admin's email address goes here> DocumentRoot /var/www/html/blog
If it’s been set, remove or comment out ServerAlias.
Next, enable the new subDomain as follows:
sudo a2ensite blog.example.com.conf
Now reload and restart the server:
$ sudo service reload apache2 $ sudo service restart apache2
And finally, set up a CNAME record for the subdomain in the parent domain’s DNS zone file.
That’s all! Go to
blog.example.html to view the contents of the subdirectory.
