This article details how to setup a rails application on a Linux VPS. Although Apache is typically used to proxy requests to Mongrel, Apache is very bloated, and is a memory hog. Many Rails applications nowadays use a previously unheard of web server called "nginx".

First, we need to install Yum:

This will make the installation of several other things we need to install faster. Now let's create a user to run our app off of. Root is not safe.
. To allow this user to sudo, we need to do the following:
type in "visudo". uncomment the line "%wheel ALL=(ALL) ALL". Type in ":write, and then :quit". This user can now sudo. now type in: passwd rails. You will be prompted to enter a new password for this user. Next, you need to log out. Log back in as that user. Use the password you just provided. Next we need to install ruby:

Next Rubygems: (if no dir /usr/local/src, create it)

Now Rails: IF THIS FAILS THE FIRST TIME, TRY AGAIN. IT *WILL* WORK

Finally, before we install mongrel, we need to install gcc

Now we can install mongrel

We should now install mysql for ruby:

Next we will create our rails app, setup the servers, configuration, and init.d scripts.
