RVM is not working over SSH

RVM is not working over SSH.

At the command-line:

leifg@host:~$ which ruby
/usr/local/rvm/rubies/ruby-1.9.2-p290/bin/ruby

Connected

Actually there's totally another, more safe and lightweight option.

You add "PermitUserEnvironment yes" somewhere to your sshd_config in /etc/(open)ssh

Now you are allowed to specify user environment in /home/user/.ssh/environment. So what do you put there ?

Just something like :

user# env | grep rvm > ~/.ssh/environment

so it looks like below :

user@app3:~$ cat ~/.ssh/environment 
rvm_bin_path=/usr/local/rvm/bin
GEM_HOME=/usr/local/rvm/gems/ree-1.8.7-2012.02
IRBRC=/usr/local/rvm/rubies/ree-1.8.7-2012.02/.irbrc
MY_RUBY_HOME=/usr/local/rvm/rubies/ree-1.8.7-2012.02
rvm_path=/usr/local/rvm
rvm_prefix=/usr/local
PATH=/usr/local/rvm/gems/ree-1.8.7-2012.02/bin:/usr/local/rvm/gems/ree-1.8.7-2012.02@global/bin:/usr/local/rvm/rubies/ree-1.8.7-2012.02/bin:/usr/local/rvm/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
rvm_version=1.14.5 (stable)
GEM_PATH=/usr/local/rvm/gems/ree-1.8.7-2012.02:/usr/local/rvm/gems/ree-1.8.7-2012.02@global

Note: this also works work user-install RVM (not only for the system wide)

Now your are able to use ruby in ssh non interactive sessions :

ssh user@app3 'ruby --version'
ruby 1.8.7 (2012-02-08 MBARI 8/0x6770 on patchlevel 358) [x86_64-linux], MBARI 0x6770, Ruby Enterprise Edition 2012.02

Voila!
