Configuration file for Apache2 and two websites

Question

I have two domains and this is my configuration file:

<VirtualHost *:80>
 ServerAdmin hello@example.com
 DocumentRoot /var/www/html/
 ServerName main-site.example
</VirtualHost>
<VirtualHost *:80>
 ServerAdmin hello@example.com
 DocumentRoot /var/www/example.com/public_html/
 ServerName second-site.example
</VirtualHost>

What I do not understand is this:

• main-site.example and www.main-site.example are accesible and point at main-site.example , so this is ok
• but www.second-site.example points to main-site.example only if I do second-site.example it works and I do not understand why

Answer 1

Add the ServerAlias directive to define your virtualHosts. Otherwise Apache will match www.second-site.example with the first *:80 VirtualHost .

<VirtualHost *:80>
  ServerName main-site.example
  ServerAlias www.main-site.example
  ServerAdmin hello@example.com
  DocumentRoot /var/www/html/
</VirtualHost>

<VirtualHost *:80>
 ServerName second-site.example
 ServerAlias www.second-site.example 
 ServerAdmin hello@example.com
 DocumentRoot /var/www/example.com/public_html/
</VirtualHost>
