Set-up Guide for Rails Server on Ubuntu

Create a ubuntu 13.04 machine at desired hosting. I prefer using Digital Ocean for me.

After creating machine, login with root user.

ssh root@

Create a user named deploy with sudo permission. We will use this to carry out all operation instead of using root user. Also choose a strong password for your user.

sudo useradd -s /bin/bash -m -d /home/deploy  -g root deploy
sudo passwd deploy
sudo usermod -a -G sudo deploy

Logout from your server and run the following command to copy your ssh keys.This will allow you to do a passwordless login via ssh.

ssh-copy-id deploy@
ssh deploy@

Run following commands to update packages already installed :

sudo apt-get -y update
sudo apt-get -y upgrade

Installing RVM

sudo apt-get -y install curl
#==========RVM ============
curl -L | bash -s stable
echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile
echo "source $HOME/.rvm/scripts/rvm" >> ~/.bashrc

Logout and login again. Check that rvm is suceesfully installed by :

type rvm | head -n 1

# It should return
rvm is a function

Installing Ruby

rvm requirements
rvm install 2.0
gem install bundler --no-ri --no-rdoc

Installing Rails

gem install rails
#== or a specific version of rails ==#

gem install rails -v 4.1.1

Setup unicorn and nginx to run rails app. Optionally you can use apache server but I am following nginx and unicorn here

#============ nginx and unicorn ===========
sudo apt-get -y install nginx
sudo apt-get -y install unicorn

Check following commands for other resuirements such as database, imagemagick, redis, memcache etc.

#============ rake===========
sudo apt-get -y install rake

#============ nodejs ===========
sudo apt-get -y install nodejs

#==============Nokogiri Dependency ===============
sudo apt-get -y install libxslt-dev libxml2-dev

#============== Memcached ===============
sudo apt-get install -y memcached

#============== Redis ===============
sudo apt-get install -y redis-server

#============== Rmagick ===============
sudo apt-get -y install imagemagick libmagickwand-dev

sudo apt-get -y install mysql-server libmysqlclient-dev

#================ Other Dependencies ================
sudo apt-get -y install build-essential libxslt1.1 libxslt1-dev libxml2 ruby-full libcurl4-openssl-dev git-core libpq-dev libreadline5 openssl libreadline6 zlib1g

#================ All in one Go ========================
sudo apt-get -y install  rake nodejs libxslt-dev libxml2-dev memcached redis-server imagemagick libmagickwand-dev build-essential libxslt1.1 libxslt1-dev libxml2 ruby-full libopenssl-ruby libcurl4-openssl-dev git-core libffi-ruby rubygems libpq-dev libreadline5 openssl libreadline6 zlib1g  mysql-server libmysqlclient-dev libmysql-ruby

Now server is ready for application to be deployed on server. In next post I will write down how can we use Capistrano for deploying application on our server.
