How to "npm start" with cluster mode on pm2 ?

Answer 1

1. the command line you have above does not seem to be correct. You wrote:

$ pm2 start npm -- start -i 0

it should be

$ pm2 start app.js -i 0

from the docs

2. I would strongly suggest using a pm2.json configuration file so you can place all your needed parameters inside and start PM2 with the Json file.

3. To check if PM2 is actually in cluster mode: PM2 list all or PM2 describe [name of app] This will show you detailed information on the running apps.

Hope this helps
