bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)  

Then add this line as the last line in your .bashrc:

If [[-s "$ HOME /. rvm/scripts/rvm "]; then source" $ HOME /. rvm/scripts/rvm "; fi is generally automatically added, you only need to re-load the configuration file (.. bashrc)

rvm notes

4. Install ruby

rvm install 1.9.2

5. Set the default ruby version

rvm --default ruby-1.9.2

6. Confirm the ruby version.

 ruby -v

7. Install rails 3.1.0 because mysql 5.1 is used at the time, and rails Versions later than 3.1 are compatible with it.

You need to switch to the Super User for installation, but root does not have the rvm environment, so first use the current user environment for root:

Env>/tmp/. env switch to root and load the Environment File:./tmp/. env. then install

gem install rails --pre --version 3.1.0.rc1

8. Install mysql

Sudo apt-get install mysql-server libmysqlclient15-dev
