In the panel, created a new user.

Installed RVM

curl -L https://get.rvm.io | bash -s stable --rails --autolibs=1

Installed ruby 2.0.0 (from binary) See:

http://stackoverflow.com/questions/15798461/how-do-i-use-rvm-to-install-ruby-on-a-dreamhost-shared-server

Add to .profile:

unset GEM_PATH

Install the bundler gem into the (global? -- append @global) gemset for the desired ruby version. Then install the gems.

rvm 2.0.0-p247
gem install bundler
bundle install

Created a new subdomain and point to the AppName/public folder for the new user

Copy the git repository to the server as an archived repo. See: http://stackoverflow.com/questions/1402390/git-push-clone-to-new-server/1402783#1402783

Used FTP to transfer to the home folder (~/)

Extracted the archive to AppName.git then deleted existing AppName directory (rm -r ./AppName)

Then git clone AppName.git

Ran bundle install from the AppName directory

Add remote to local repository

git remote add master user@ftp.site.com:~/AppName.git 

Monitoring remotely:
