This article covers a version of Ubuntu that is no longer supported. If you are currently operate a server running Ubuntu 12.04, we highly recommend upgrading or migrating to a supported version of Ubuntu:
Reason: Ubuntu 12.04 reached end of life (EOL) on April 28, 2017 and no longer receives security patches or updates. This guide is no longer maintained.
This guide might still be useful as a reference, but may not work on other Ubuntu releases. If available, we strongly recommend using a guide written for the version of Ubuntu you are using. You can use the search functionality at the top of the page to find a more recent version.
Ruby on Rails is an application stack that provides developers with a framework to quickly create a variety of web applications. Ruby on Rails does take a little while to install on a virtual server, but luckily there are a lot of helpful tools to make this process as easy as possible. You can run this tutorial on your droplet as a user with sudo privileges. You can check out how to set that up here: Ubuntu Server Setup
Before we do anything else, we should run a quick update to make sure that all of the packages we download to our VPS are up to date:
sudo apt-get update
Once that's done, we can start installing RVM, Ruby Version Manager. This is a great program that lets you use several versions of Ruby on one server; however, in this case, we will just use it to install the latest version of Ruby on the droplet.
If you do not have curl on your system, you can start by installing it:
sudo apt-get install curl
To install RVM, open terminal and type in this command:
\curl -L https://get.rvm.io | bash -s stable
After it is done installing, load RVM. You may first need to exit out of your shell session and start up a new one.
In order to work, RVM has some of its own dependancies that need to be installed. To automatically install them:
You may need to enter your root password to allow the installation of these dependencies.
On occasion the zlib package may be reported as missing. The RVM page describes the issue and the solution in greater detail here.
Once you are using RVM, installing Ruby is easy.
rvm install ruby
The latest ruby is now installed. However, since we accessed it through a program that has a variety of Ruby versions, we need to tell the system to use the version we just installed by default.
rvm use ruby --default
The next step makes sure that we have all the required components of Ruby on Rails. We can continue to use RVM to install gems; type this line into terminal.
rvm rubygems current
Once everything is set up, it is time to install Rails. To start, open terminal and type in:
gem install rails
This process may take a while, be patient with it. Once it finishes you will have Ruby on Rails installed on your droplet.
Once you have installed Ruby on Rails on your server, you can proceed to Create a SSL Certificate for your site or Install an FTP server

I want to install RVM in ubuntu and i am folling these steps
root@jaskaran-Vostro-1550:/home/user_name# sudo apt-get install curl
done this successfully
root@jaskaran-Vostro-1550:/home/user_name# curl -L https://get.rvm.io | bash -s stable
done this successfully
but when i run this command
root@jaskaran-Vostro-1550:/home/user_name# source ~/.rvm/scripts/rvm
result like that
bash: /root/.rvm/scripts/rvm: No such file or directory
what wrong in this
A friend got an error about a public key not being found with the command
This one from rmv.io solved it
Great tuto and thanks!
For those of you having trouble with this step: source ~/.rvm/scripts/rvm
no such file or directory found
and you were not signed in as root, then most likely you got something like this during your curl command: gpg: Can’t check signature: public key not found
run the following command: gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
as per: http://stackoverflow.com/a/28584326/4260179
source ~/.rvm/scripts/rvm should work now!
This tutorial has stood the test of time! I was able to get things up-and-running in a vagrant box using it with one addition:
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
Is required before you get cURLing. Thanks for writing this up!
hello all while installing RVM , I stuck here Error running 'requirements_debian_libs_install gawk
You must read this tutorial on Buffercode and add solution for these errors .
Etel, you really know how to write tutorials! Thank you very much!
Be aware , the step
can take forever, because of ri documentation install So if you are not developer and docs are not needed within a server - use
command, that is much faster
please add --no-ru --no-rdoc on gem install rails it takes at least 10 time longer otherwise
gem install rails --no-ri --no-rdoc
Regarding this error: mkdir: cannot create directory `/usr/local/rvm/log/ruby-2.0.0-p195’: Permission denied
I fixed it by adding the ‘rvm’ group to my user.
