Set up Rails envirenment on AWS

This README file explains how to set up the AWS EC2 instance with Ubuntu, Apache, postgreSQL and Ruby on Rails

GET STARTED

1. Click the follwing link, will take you to the AWS marketplace to begin setting up your EC2 instance https://aws.amazon.com/marketplace/pp/B00JV8XNKQ/ref=gtw_msl_image?ie=UTF8&pf_rd_r=05ZA3J50A153TVH69TTW&pf_rd_m=A33KC2ESLMUT5Y&pf_rd_t=101&pf_rd_i=awsmp-gateway-1&pf_rd_p=1825567482&pf_rd_s=right-3

2. Assuming you have setup your aws account, select your region and click continue

3. Choose your Instance type and following directions to set up your key pair. When creating a key pair, .pem file will be downloaded. Put this file in a safe place because you’ll need it to access SSH and FTP

4. Launch

SSH

1. SSH username is Ubuntu

2. Get the public DNS. In the AWS EC2 console click on the instance, see below. it looks like this: ec2-54-187-205-42.us-west-2.compute.amazonaws.com

3. Open Terminal and follow the steps below. You'll need your private key you downloaded early.

 $ cd/dir/privatekeydir
 $ chmod 400 mykey.pem
 $ ssh -i private_key.pem ubuntu@ec2-public-dns-.us-west-2.compute.amazonaws.com

INSTALL Ruby

STEP 1: Get some dependencies

$ sudo apt-get update
$ sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev 
$ sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties

STEP 2: Install Ruby with RVM

sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc
rvm install 2.1.2
rvm use 2.1.2 --default
ruby -v

STEP 3: Tell Rubygems not to install the documentation for each package locally

echo "gem: --no-ri --no-rdoc" > ~/.gemrc

INSTALL Rails

STEP 1: Install Node.js

To install NodeJS, we're going to add it using a PPA repository:

sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

STEP 2: Now install Rails

gem install rails

run raisl -v to check everything is installed correctly

rails -v

INSTALL PostgreSQL

STEP 1: add a new repository and easily install

sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-common
sudo apt-get install postgresql-9.3 libpq-dev

STEP 2: Set up Postgres User

sudo -u postgres psql postgres

# \password postgres

Enter new password: 

Create new rails app

rails new myapp -d postgresql
cd myapp
rake db:create
rails server

You'll probably get this error in terminal

FATAL: Peer authentication failed for user "postgres"

ou need to make a small shange to your pg_hba.conf locate /etc/posgresql/9.3/main/

$ cd /etc/postgresql/9.3/main
$ sudo pico ph_hba.conf

INSTALL APACHE

sudo apt-get update
sudo apt-get install apache2

More details: https://www.digitalocean.com/community/tutorials/how-to-configure-the-apache-web-server-on-an-ubuntu-or-debian-vps

INSTALL PASSENGER

Passenger is going to help you launch your ruby app

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

Following the instructions diring installing of passenger

- sudo pico apache2.conf
- cd sites-available
- sudo pico 000-default.conf
- Must restart server when changes are made to yml files


- add this line to apache conf
   LoadModule passenger_module /home/ubuntu/.rvm/gems/ruby-2.1.2/gems/passenger-4.0.45/buildout/apache2/mod_passenger.so
   <IfModule mod_passenger.c>
     PassengerRoot /home/ubuntu/.rvm/gems/ruby-2.1.2/gems/passenger-4.0.45
     PassengerDefaultRuby /home/ubuntu/.rvm/gems/ruby-2.1.2/wrappers/ruby
   </IfModule>
