It’s not very original but i will describe how i installed my rails application on my ubuntu server 12.10. It will serve as a good reminder for me too.
creating rails user
The best is to create a dedicated user for rails applications. Without specific privileges like sudo or thing like that.
sudo groupadd rails sudo useradd -m -s /bin/bash -g rails rails
rvm and packages installation
Like shown on rvm website, we will use curl to install rvm :
sudo aptitude install curl sudo su - rails curl -L https://get.rvm.io | bash -s stable
It will add this line in .bash_profile :
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
rvm script work very well and can install directly all needed packages for ruby compilation by using sudo.
If you don’t want to add sudo to your rails user, it’s possible to see what are the needed packages with rvm requirements command.
So, on ubuntu, you should install the following packages :
sudo aptitude install gawk g++ gcc make libc6-dev libreadline6-dev zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 autoconf libgdbm-dev libncurses5-dev automake libtool bison pkg-config libffi-dev
I will use postgresql as database and imagemagick for image manipulation in rails.
sudo aptitude install postgresql-9.1 postgresql-client-9.1 postgresql-server-dev-9.1 sudo aptitude install imagemagick libmagickwand-dev
All the operations are done under the rails user.
We start by installing ruby 2.0.0 :
rvm install ruby-2.0.0
rvm use ruby-2.0.0@globals rvm install rails
I will end here the first part of installation. In the next part, we will see how to configure postgresql and nginx.
