Brain dump warning!

This is a follow up to Installing ruby 2 + Rails 4 on Ubuntu 12.04 LTS and is just a list of steps needed to get a clean install of Ubuntu up to speed with an existing site.

Install rbenv to manage ruby versions
https://github.com/sj26/rbenv-install
git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
Install ruby-build to manage installation of ruby versions into rbenv
https://github.com/sstephenson/ruby-build
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
For convenience install dotmatrix - this will set up the rbenv environment correctly, amongst other things
clone https://github.com/timabell/dotmatrix
run bin/install
restart any running terminal(s) to get rbenv
get a project (includes a .ruby-version file for rbenv, and a Gemfile for bundle)
git clone git@github.com:timabell/symbol-library.git
sudo apt-get install libssl-dev libreadline-dev
readline is needed for rails console, and has to be installed before ruby. If you’ve already installed ruby then just re-run rbenv install and it will overwrite the existing build with a version with readline support. ref: http://vvv.tobiassjosten.net/ruby/readline-in-ruby-with-rbenv/
rbenv install x.x.x-xxxx
autocompletes, yay!
.. or better still reads from .ruby-version I think so you can just run rbenv install if you are in the project folder
gem install bundler
from the right directory so done for right ruby version
- rbenv rehash
bundle
will install all the gems for the project
~~don’t sudo apt-get install rbenv~~ ~ doesn’t provide sufficiently up to date ruby
~~don’t gem install rails --version 4.0.2 --no-ri --no-rdoc~~ ~ don’t need this when you have a gem file with rails in it, bundle will do it for you
sudo apt-get install nodejs
for javascript runtime (rails server throwing an error without this)
bundle exec rails server
bundle exec rails console
needs readline (see above)

Other stuff I like in my install

dotmatrix bin/vimbundles
- includes vim-rails and friends
- full list https://github.com/timabell/dotmatrix/blob/master/bin/vimbundles.sh#L45
console colours from bin/solarize.sh in dotmatrix/bin
tmux

This is mostly for my own reference but maybe it’ll help someone else out.
