How I installed Rails
First install Ruby:
I tried to avoid using sudo. I don't remember exactly when I used sudo in the steps below. When you see "sudo", that's a post-install guess that I probably used it there.
sudo apt-get -y update
sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz
tar -xvzf ruby-2.0.0-p247.tar.gz
cd ruby-2.0.0-p247/
./configure --prefix=/usr/local
make
sudo make install
----------------------
I installed Rails by following this web page:
https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm
Noting the relevant bits here in case that page goes down/changes:
sudo apt-get update
sudo apt-get upgrades
sudo apt-get install curl
This installs RVM. RVM is a Ruby version manager. I want this in case I need to use different versions of Ruby (maybe later).
\curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm requirements
I don't know if this next part might be redundant. I wonder if I should have installed RVM first, before installing Ruby.
rvm install ruby
rvm use ruby --default
This installs rubygems. Not sure what gems are. Wikipdedia says:
RubyGems is a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self-contained format called a "gem"), a tool designed to easily manage the installation of gems, and a server for distributing them.
rvm rubygems current
This installs rails:
gem install rails
----------------------
Currently trying to follow this introductory Rails guide:
http://guides.rubyonrails.org/getting_started.html
The guide assumes I have SQLite3 installed. I think this installed sqlite3:
sudo apt-get install sqlite3 libsqlite3-dev
sudo gem install sqlite3-ruby
I don't recall if I had to configure stuff for sqlite3. There may have been on-screen instructions I had to follow.
