Apache 2 Sites-Available Configuration

You need a ServerName directive inside the <VirtualHost>. It will tell the server which virtual host is currently in use depending on the browser request (if your client access http://site1.example.com or http://site2.example.com, they will connect to the same IP, hence server, but the request contains the original request url).You'll have to duplicate your <VirtualHost> block to have one per hosted site. Each block will differ by their ServerName and DocumentRoot mainly.You can use "apache2ctl -S" to see how apache understood your virtual host settings.

You can use a single file with this kind of content :

<VirtualHost *:80>  ServerName site1.myserver.com  DocumentRoot /var/www/site1  ...</VirtualHost><VirtualHost *:80>  ServerName site2.myserver.com  DocumentRoot /var/www/site2  ...</VirtualHost><VirtualHost *:80>  ServerName site3.myserver.com  DocumentRoot /var/www/site3  ...</VirtualHost><VirtualHost *:80>  ServerName site4.myserver.com  DocumentRoot /var/www/site4  ...</VirtualHost><VirtualHost *:80>  ServerName site5.myserver.com  DocumentRoot /var/www/site5  ...</VirtualHost>

Of course, maybe sure that the dns for all of those name ends up on your IP. It needs not to be subdomains as long as they land on your server ip and you have a correspond ServerName for it. If you need extra names for a single site, you can add them with "ServerAlias secondname.myserver.com thirdname.myserver.com" below ServerName

@Zeograd's answer is probably the correct answer for most solutions, however I had a similar issue and all I needed to do was enable the rewrite module with the a2enmod command.

This is what I ran via command line in Ubuntu:

sudo a2enmod rewritesudo service apache2 restart

If sudo service apache2 restart doesn't work, you can try:

sudo /etc/init.d/apache2 restart
