Basics of setting up a VirtualHost with Apache (locally)

hosts

# /etc/hosts 
127.0.0.1       localhost
127.8.8.8       fuckyouverymu.ch 
127.0.0.8       atariba.se
127.0.0.3       typo3.local

127.0.0.5       my-awesome-site.local

# In my browser I can now use http://fuckyouverymu.ch to see my localhost (because I have no site.conf for fuckyouverymu.ch at the moment :D) 

your-site.conf

# A IP + Port, I used 127.0.0.5 to seperate if from the "normal" localhost
<VirtualHost 127.0.0.5:80>
        ServerName my-awesome-site.local          # the site's URL
        ServerAdmin webmaster@localhost           # can be anything
        DocumentRoot /var/www/my-awesome-site     # the site's root folder
</VirtualHost>

# That's it, the minimal config. I think it'd be possible to leave the ServerAdmin part away. 
# There is a lot of more stuff that can be configured.
# A sample file can be copied from "000-default.conf" in /etc/apache2/sites-available (Linux)
# Mac OS dir should be /private/etc/apache2/other/ 

# Next you just need to set up the host in your hosts etc so that the URL points to the virtual host.
