How To Subdomain Localhost — Ubuntu / OSX

Using Gnome + Ubuntu (7.04 Feisty Fawn) + Apache 2

Step 1:
In gnome goto System -> Administration -> Network and click on the ‘Hosts’ tab

Step 2:
For your normal localhost (127.0.0.1) double-click or hit ‘properties’ to edit it. Add your list of subdomains under localhost.

*Ignore the text in this pic, I overlooked that you had to include _all_ aliases in the same box. Whoops

Step 3:
The fun step
Open a terminal and type sudo gedit /etc/apache2/sites-available/default — assuming you’re using the “default” httpd.conf. Chances are that you will be, and if you aren’t you should know what file I’m talking about anyway. (If you don’t, just load one of the enabled apache configuration files)

Change these lines:

NameVirtualHost *
<VirtualHost *>

to

NameVirtualHost 127.0.0.1
<VirtualHost 127.0.0.1>

Step 4:
Add the following (for each subdomain you made) — changing the ServerName to whatever you aliased in the network host dialogue and DocumentRoot to wherever you want the subdomain to point.

<VirtualHost 127.0.0.1>
	ServerName mysql.localhost
	DocumentRoot /var/www/phpmyadmin
</VirtualHost>

Step 5:
In a terminal type: sudo apache2ctl restart
When that finishes, browse to http://mysql.localhost and you should see phpMyAdmin (going by my example)

On OSX + Apache 1.33

Step 1:
Open /Applications/Utilities/NetInfo Manager and click on “machines”
I usually just duplicate the localhost settings, or just create a new record below localhost that is something like:

ip_address: 127.0.0.1
name: mysql.localhost
serves: ./local

Step 2:
Repeat Steps 3-5 above only editing “/etc/httpd/users/{yourname}.conf” instead.

Click for bigger version

Restart Apache and hopefully all went well. I found this useful because I hate typing unnecessary paths
