Rails - to create a blog site Part 1

Tutorial that I am following is from this site : http://guides.rubyonrails.org/getting_started.html


I choose to sudo as root to avoid the permission issue.

$ sudo su 

Install Ruby

$ apt-get install rubygems

Install Rails

$ gem install rails

Create a blog application

$ rails new blog

Note : You might encounter this error.

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension

To solve this, install sqlite before create the blog application.

$ apt-get install libsqlite3-dev
$ gem install sqlite3 -v '1.3.6'

Create a database

$ rake db:create

You might encounter this error.

rake aborted!

Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.

Go to the created blog directory. Edit this file : Gemfile.
Uncomment this line :

gem 'therubyracer', :platform => :ruby

Run this (installing nodejs and also reinstall rails) :

$ apt-get install nodejs
$ bundle install

To start the web server

$ rails server

You can access the new project site at http://0.0.0.0:3000.

P/S : I am running on Ubuntu 12.04.
