How to run multiple app using PM2?

Question

I want to run my angular4 app using PM2 it will run but when I am close the terminal it will stop.

1. On this server already run one application, it is working properly, but in my app it will work when I am open the terminal, otherwise it will stop

   pm2 start server.js

I am using this command to run my app but when I am Close the Terminal immediately it will stop, so how can I run this app Forever using PM2.

The question is misleading and conceals real problem. The purpose of PM2 is to run the app 'forever', regardless of whether terminal window is open or not. – Siddra

@estus the other one is working properly but the second one is running stop when i close the Terminal, Do you have any proper solution? should i run this command as a ROOT? – Circumfluous

@Chaudhary You still having problem?? – Les

@Vishantdhandha still having same problem. – Circumfluous

Answer 1

If you are using PM2 properly, your applications should not be turning off after terminal exit. It is very likely that your application is failing. Run pm2 logs to diagnose.

You can specify multiple applications in a process.json file like this:

{
    "apps" : [{
        "name"        : "worker",
        "script"      : "./worker.js",
        "watch"       : true,
        "env": {
            "NODE_ENV": "development"
        },
        "env_production" : {
            "NODE_ENV": "production"
        }
    },{
        "name"       : "api-app",
        "script"     : "./api.js",
        "instances"  : 4,
        "exec_mode"  : "cluster"
    }]
}

Started like this:

pm2 start process.json

And can monitor/view your applications by running pm2 monit or pm2 ls

Answer 2

You can start any NodeJs server using pm2 start ****.js --name "Project Name".

You can check that server is online or not.

Answer 3

If you are running the same script multiple times, with different parameters for instance, just give them different names.

i.e.

PM2 Start Engage.js --name Warp1

PM2 Start Engage.js --name Warp2

PM2 Start Engage.js --name Impulse
