run pm2 from remote shell script
I am trying to write a script which ssh into a bunch of my servers and runs some commands to start my app. One of the commands (pm2) always says pm2: command not found. This is how I'm attempting this:
ssh -o StrictHostKeyChecking=no -i /Path/to/key-pair.pem ubuntu@${ec2ips[i]} 'bash ' << 'STARTAPP'
cd ~/my-app-folder
pm2 start ./bin/www --name 'my-app'
exit
STARTAPP
when I ssh in normally, all pm2 commands run fine. If I ssh in and run a script with pm2 in it, it also works as expected. It's only when I try and run it on a remote machine from my machine.

When you run an interactive shell it sets the PATH variable according to your "rc" files (e.g .bash_profile). When you run that "non-interactive" ssh command then many of these scripts aren't run and so PATH isn't set.
You should include the pathname to pm2 even if it is the current directory (eg ./pm2 or /path/to/pm2) to ensure it is found, or else export PATH=.... before the call to pm2.

i did 'which pm2' which should get me the path to the executable, correct me if i'm wrong. then i tried doing /home/ubuntu/.nvm/versions/node/v6.0.0/bin/pm2 start ./bin/www --name 'my-app' but that is still giving me command not found. did i misunderstand your solution?

The point is your execution environments are different; doespm2use other variables to find things? Login and run theenvcommand and compare that tossh server env; there will be a LOT of differences. Do any of those variables impact the execution of the command?

pm2 use other variables to find things? Login and run the env command and compare that to ssh server env; there will be a LOT of differences. Do any of those variables impact the execution of the command?– Stephen Harris
