Setup a Ubuntu VPS for Ruby on Rails Application

In this section, my VPS using Ubuntu Server OS

1. Connecting to your server

Login using SSH, as the root user

ssh root@100.100.100.100  #VPS IP Address
password: {your_password}

2. Create a new User

Add a new user to instead the root user

adduser your_username
password {enter_the_password_user}

3. Update the ubuntu

Make sure the Ubuntu is up date

sudo apat-get update

4. Install nano text editor

sudo apat-get install nano

5. Install RVM (Ruby Version Manager)

Firstly, we'll install the Curl

sudo apat-get install curl

Then, install the RVM

\curl -L https://get.rvm.io | bash -s stable

After installing is done, load the RVM. You may first need to exit out out your shell session (terminal) and start up a new one

source ~/.rvm/scripts/rvm

6. Install Ruby with RVM

First, RVM will check the dependencies to install ruby

rvm requirements

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

Now we can list all the availabel versions of Ruby that are available:

rvm list known

Will show list all Ruby version like this:

# MRI Rubies
