Install Ruby on Rails 3 on Debian 6 (Squeeze) using RVM

First at all I decided to install Ruby & RoR using RVM because (yup, imma RoR n00b) seems to be a really common thing to switch between ruby versions,gems and anything while developing any kind of ror apps.
Also, because Debian version is (of course) outdated and besides that i ran into a lot of problems while i was trying to install it using the packages... Yeah, gotta love Debian <stable>. Errors like:

• File not found: lib.
• Execjs: Could not find a JavaScript runtime
• And so on...

First some packages that you probably already have if you are a developer:

apt-get install curl git-core

Now because RVM downloads and compiles a LOT of the stuff we are installing you'll need:

apt-get install build-essential openssl libreadline6 libreadline6-dev zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison

(Again, if you are a developer you might already have some of em installed)

And this one if you plan to use Mysql on your project:

apt-get install libmysqlclient-dev

Here, make sure you don't have any Ruby packages installed and begin installing RVM (and from now on don't run anything as root):

bash < <(curl -sk https://rvm.beginrescueend.com/install/rvm)
echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile

Now if you are a Gnome user make sure to check this option on your Terminal profile perferences (don't ask me why, just do it™ ):

To continue restart your Terminal, then:

// Checks if rvm is installed correctly (it MUST return 'rvm is a function')
$> type rvm | head -1

// Install Ruby and make sure it works
$> rvm install 1.9.2
$> rvm use 1.9.2
$> ruby -v

// Create a new gemset and install Rails
$> rvm gemset create rails305
$> gem install rails -v 3.0.5

// SQlite database extension
$> gem install sqlite3

// MySQl database extension
$> gem install mysql2

At this point if everything went OK you are good to go, still I recommend ya to run a simple app to make sure:

rails new HelloWorld
cd HelloWorld
rails server

Install MongoDB PHP driver on Debian 6 Squeeze

Install the server

apt-get install mongodb-server

Before install the PHP driver a couple of packages you'll need:

apt-get install php5-dev build-essential php-pear

Now time to compile/install the driver:

pecl install mongo

Once it finishes it will display the location of the new extension. Something like:

/usr/lib/php5/20090626/mongo.so

Finally add this to your php.ini (/etc/php5/cgi/php.ini):

extension=/usr/lib/php5/20090626/mongo.so

Now restart your web server and that's should be it!

Symfony2's "Upgrade your APC extension (3.0.17+)" problem

Somehow Symfony2 Standard (2.0.0) have a bug on the installer that produces an error while it checks APC version. (even if you don't have it installed it, APC is NOT a requirement for SF2)

Here is the patch to fix it:

http://pastebin.com/raw.php?i=dwaM0uCC

Btw, This patch has already been commited to SF git, (not yet released).

Run Zend Framework (1.11) on lighttpd

Make sure this two mods are enabled on yer lighttpd.conf:

mod_rewrite

mod_setenv

And add this to your host config:

$HTTP["host"] == "localhost" {
  url.rewrite-if-not-file = (
    ".*\?(.*)$" => "/index.php?$1",
    "" => "/index.php"
  )

  # Not necessary, but most of Zend applications use it
  setenv.add-environment = (
    "APPLICATION_ENV" => "development"
  )
}
