CodeDeploy PM2 Command Not Found

Question

I'm trying to use AWS CodeDeploy to deploy my application. Everything seems to be working fine but I'm getting the following error.

[stderr]/opt/codedeploy-agent/deployment-root/f1ea67bd-97bo-08q1-b3g4-7b14becf91bf/d-WJL0QLF9H/deployment-archive/scripts/start_server.sh: line 3: pm2: command not found

Below is my start_server.sh file.

#!/bin/bash
pm2 start ~/server.js -i 0 --name "admin" &

I have tried using SSH to connect to my server as user ubuntu and running that bash file and it works perfectly with no errors. So I know that PM2 is installed and working correctly on that user.

Below is also my appspec.yml file.

version: 0.0
os: linux
files:
  - source: /
    destination: /home/ubuntu
hooks:
  ApplicationStart:
    - location: scripts/start_server.sh
      timeout: 300
      runas: ubuntu
  ApplicationStop:
    - location: scripts/stop_server.sh
      timeout: 300
      runas: ubuntu

Also not sure if this will help but here is my stop_server.sh file.

#!/bin/bash
npm install pm2 -g
pm2 stop admin || true
pm2 delete admin || true

Any ideas?

Answer 1

Perform the below steps:

1. which node
2. sudo ln -s /home/ubuntu/.nvm/versions/node/v12.13.1/bin/node (output of above step) /usr/bin/node
3. which pm2
4. sudo ln -s /home/ubuntu/.nvm/versions/node/v12.13.1/bin/pm2 (output of above step) /usr/bin/pm2

in start_server.sh and stop_server.sh use it as below (run start.sh as ubuntu):

sudo /usr/bin/pm2 status

Hope this will help you!!

Answer 2

Usually in cases like that is to use full path to pm2.

#!/bin/bash
/usr/local/bin/pm2 start ~/server.js -i 0 --name "admin" &
