在Ubuntu 14.04上安装ruby的合适方法是什么

Question

I have a computer serves as a server. I have bitnami-gitlab stack on it. And now I want to install my rails app to this server. The thing confuses me, bitnami-gitlab has ruby interpreter and other apps (rails , gem, bundler etc.). Gitlab application uses git user on ubuntu. When I type;

sudo su git
which ruby

It gives me the directory of ruby which is inside of bitnami installation directory. Now, I want to install ruby, rails, apache and passenger to deploy my rails app. What is the appropriate way to do? I want to start my rails app as boot time. Should I install ruby to root user or my own user? When I install ruby, will my gitlab application crahs?

Here is how I do it >

First, update apt-get:

sudo apt-get update

Then if you do not have it install Curl, for installing RVM

 sudo apt-get install curl

Then run the appropriate RVM install there are multiple options like added rails, puma JRuby etc. check RVM website for more info. For just ruby run >

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

Now exit the shell session and start a new one

source ~/.rvm/scripts/rvm

RVM has its own requirements that can be auto installed by running >

rvm requirements

Now managing you ruby environments is easy and you can have multiple versions without making a mess.

To install any ruby version you need just run (xxx) version of the ruby>

rvm install x.x.x

To list versions you have installed run >

rvm list 

Note also that now you can specify in your GEMFILE what version to use. Simply add ruby 'xxx' and rvm uses the version you specified as long as its already installed. Not having it raises error.
