Code Sapling

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@123.45.67.89

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@123.45.67.89
ssh deploy@123.45.67.89

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 https://get.rvm.io | 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

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

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

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.
