Switch from fork to cluster mode in pm2

Question

I have a pm2 managed app that runs in fork mode . How can I switch it to cluster mode ?

Answer 1

You can take a look at this document .

Stop and delete your current app run on the pm2.

pm2 stop ${your app name}
pm2 delete ${your app name}

And rerun your app with arguments -i max :

pm2 start path/to/main.js -i max --name="${your app name}"
// Should use pm2 not pm

Or create a json config file and run your app with it

// processes.json
{
  "your-app-name" : [{
    "script"    : "path/to/main.js",
    "instances" : "max",
    "exec_mode" : "cluster"
  }]
}

pm2 start processes.json

Answer 2

Switch app to Cluster Mode

$ pm2 reload all                # Reload all apps in cluster mode
$ pm2 gracefulReload all        # Graceful reload all apps in cluster mode
