AWS EC2和rvm ssh

Question

I have created user for my AWS ec2 VPS (deployer)

When i am logging with:

ssh -i ~/.ssh/aws/*...*.pem ubuntu@ec2*...*.amazonaws.com

command rvm use 2.0.0 is working correctly

=>

    ubuntu@ip-***:~$ rvm list

    rvm rubies

    =* ruby-2.0.0-p247 [ x86_64 ]

    # => - current
    # =* - current && default
    #  * - default

    ubuntu@ip-***:~$ rvm which
    ubuntu@ip-***:~$ 

But when i use su - deployer i have got:

deployer@ip***:/home/ubuntu$ rvm
    The program 'rvm' is currently not installed. You can install it by typing:
    sudo apt-get install ruby-rvm

I would like to understand how correctly write command for ssh login. I have tried:

ssh -i ~/.ssh/aws/*.pem *ubuntu@ec2***.amazonaws.com -t 'bash --login -c "rvm"'

but received "Connection to ec2- * .amazonaws.com closed".

Within my local machine rvm functioning correctly. I have added

  [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function* 

into my ~/.bash_profile

I have spent 3-5 hours studying stackoverflow topics related to this issue, but still not understand what am i doing wrong.

Any help will be highly appreciated! Thanks in advance!

Answer 1

I've run into this problem before and there are 2 ways to solve it.

The first way is to log in directly as the deployer user to the instance. This might mean having to create a ssh keypair (see ssh-keygen -t rsa). Then you can log in with ssh deployer@ec2.instance.address This way the rvm will be loaded directly to the deployed user's shell.

A second way is not to use the dash when su to the deployed user account.

When you use the dash then you load your own bashrc vs that particular user's bashrc.

So sudo su deployer

Answer 2

you nee to use:

su - deployer

it will ensure you use login shell
