[Whole Web, Node.js, PM2] Configuring PM2 for Node applications

In this lesson, you will learn how to configure node apps using pm2 and a json config file.

Let's say there are tow node apps: app1, app2.

 

What we want to do is create a json fie as config file for pm2.

pm2.config.json:

{
  "apps": [{
    "name": "App1",
    "script": "app1/server.js"
  },{
    "name": "App2",
    "script": "app2/server.js"
  }]
}

 

app1/server.js:

var http = require("http");
var server = http.createServer(function(request, response){
    response.writeHead('200', {"Content-Type": "text/plain"});
    response.end("Hello from app1");
});
server.listen(3000);
console.log("Listen on port 3000");

 

app2/server.js:

var http = require("http");
var server = http.createServer(function(request, response){
    response.writeHead('200', {"Content-Type": "text/plain"});
    response.end("Hello from app2");
});
server.listen(3001);
console.log("Listen on port 3001");

 

Usage:

pm2 start pm2.comfing.json
