rvm --version  

//OP:rvm 1.8.4 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]
 

6. Install ruby 1.8.7 or 1.9.2 (according to your need)
rvm install 1.8.7

7. Set default ruby 1.8.7 
rvm --default use 1.8.7

8. Create gemset for rails3 application (you can name it as you wish) 
rvm gemset create rails3

9. Use the rails3 gemset on ruby 1.8.7
rvm use 1.8.7@rails3

10. Final Step

git clone your_project ; gem install bundle ; bundle check 

Manage git repos on S3

Use jgit to manage git repos on Amazon S3

Download jgit.sh from here and put jgit in your $HOME path

Make a .jgit file in your home directory and put

accesskey: *******************
secretkey: ********************



Make a bucket for git repos say git-repos

Now got to your project directory and add a remote for Amazon S3

>cd git_project

>git remote add s3 amazon-s3://.jgit@git-repos/git_project.git



>git push s3 branch

and it's done.
