Set a local domain to ease local development
If you’re a web developer you probably do a fair amount of development on your local machine using either the built-in Mac OS X Apache server or, in my case, something like MAMP. You can make your local development life a bit easier by setting a local domain, here’s how.
from the Mac Terminal type the following:
sudo nano /etc/hosts
this will bring up the /etc/hosts file in the nano editor, it will look something like this:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
next, you’ll want to add the hostname (in this case, local.dev) you’d like to use locally to the end of that file on a new line, in the following format:
Save the changes to /etc/hosts file by hitting Control-O and then Control-X to exit. Now you can access your local domain via the web browser, ftp, or whatever other means.
