How to install LAMP + Passenger on a EC2 Amazon AMI (mod_passenger + dependencies)

Many thanks to aronwoost for his great EC2 Lamp gist that this is forked from. I've modified parts of it, specifically around phpmyadmin configuration.

This gist additionally covers installing Phusion Passenger, Ruby Gems, all dependencies and the final configuration to get you up and running ASAP.


#LAMP Setup

Launch the instance and connect with ssh.

##Update the server

sudo yum update

##Install php and MySQL packages

sudo yum install https mod_ssl mysql mysql-server php php-mysql php-xml

##Install phpMyAdmin

Get the RPMforge repo (32-bit, for 64-bit use http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm)

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
sudo rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Install

sudo yum install phpmyadmin

##Start MySQL service

cd /etc/rc.d/init.d/
sudo ./mysqld start
sudo /usr/bin/mysql_secure_installation //follow instructions

##Setup startup scripts for apache and MySQL

cd /etc/rc.d/rc3.d
sudo rm K15httpd
sudo rm K36mysqld
sudo ln -s ../init.d/mysqld S30mysql
sudo ln -s ../init.d/httpd S85httpd

##Setup phpMyAdmin

Allow access from external IP's

sudo chmod 0700 /etc/httpd/conf.d/phpmyadmin.conf
sudo nano /etc/httpd/conf.d/phpmyadmin.conf
#  Web application to manage MySQL
#  #
#  Order Deny,Allow
#  Deny from all
  Allow from 127.0.0.1
#
Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin

Note: Leaving the default path to phpmyadmin is not generally a good idea. Feel free to change this to whatever you like to help thwart script kiddies looking for vulnerabilities, and I recommend you disable this completely in a production environment just to be on the safe side.

###Examples###

Non-standard location:

Alias /happily_hidden_phpmyadmin /usr/share/phpmyadmin
#Alias /phpmyadmin /usr/share/phpmyadmin
#Alias /phpMyAdmin /usr/share/phpmyadmin
#Alias /mysqladmin /usr/share/phpmyadmin

Remove completely:

#Alias /phpmyadmin /usr/share/phpmyadmin
#Alias /phpMyAdmin /usr/share/phpmyadmin
#Alias /mysqladmin /usr/share/phpmyadmin

I've commented them out for visual effect, you could just delete them completely but useful to leave one in place for easy switching later if you need access.

Set blowfish_secret to make it work with cookie auth

sudo chmod 0700 /usr/share/phpmyadmin/config.inc.php
sudo nano /usr/share/phpmyadmin/config.inc.php 
...
$cfg['blowfish_secret'] = 'put-a-magic-string-here'; /* YOU MUST FILL IN THIS FOR COOKIE AUTH! */
...
sudo chmod 0755 /usr/share/phpmyadmin/config.inc.php

##Make mod_rewrite (.htaccess) work in subdirectories

cd /etc/httpd/conf
sudo nano httpd.conf

Find <Directory "/var/www/html"> Replace AllowOverride none with AllowOverride all

(optional if apache is running already, restart it)

sudo service httpd restart

##Start apache

sudo /etc/rc.d/init.d/httpd start

#Install Passenger

##Install many dependencies

cd ~
sudo yum install ruby-devel
sudo yum install mysql-devel
sudo yum install sqlite-devel //You might not need this but I installed as part of my process
sudo yum install make
sudo yum install gcc46
sudo yum install curl-devel
sudo yum install openssl-devel
sudo yum install httpd-devel
sudo yum install gcc-c++

If you get an error like:

* Zlib development headers... not found

Make sure gcc-c++ installed correctly.

##Install Ruby Gems

Try:

sudo yum install rubygems

If this fails, do this:

wget http://production.cf.rubygems.org/rubygems/rubygems-1.8.24.tgz
tar xvzf rubygems-1.8.24.tgz 
sudo ruby rubygems-1.8.24/setup.rb

##Install Passenger and Apache module

sudo gem install passenger
sudo passenger-install-apache2-module

Follow the on screen instructions to configure Apache, but it goes a little something like this. Open up httpd.conf for editing:

sudo nano /etc/httpd/conf/httpd.conf

And add the following lines to the end of file:

LoadModule passenger_module /usr/lib64/ruby/gems/1.8/gems/passenger-3.0.17/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib64/ruby/gems/1.8/gems/passenger-3.0.17
PassengerRuby /usr/bin/ruby

Find the following separate lines in your conf:

...
DocumentRoot "/var/www/html"
...
<Directory "/var/www/html">
...
Options Indexes FollowSymLinks
...

And amend respectively:

...
DocumentRoot "/var/www/html/public"
...
<Directory "/var/www/html/public">
...
Options -Indexes FollowSymLinks -MultiViews
...

Note: I've disabled indexes for security reasons and because it's good practice. You can enable / disable them as you wish; it won't impact Passenger.

##Create your public directory and reload httpd

sudo mkdir /var/www/html/public
sudo /etc/rc.d/init.d/httpd restart

Finished. Happy coding.

If you're new to Ruby, I can't recommend Sinatra enough as an easy to use framework.
