start forever command on ubuntu to run js file

Question

I have installed forever and forever-monitor on ubuntu in below path /var/www/html/node_modules

Now I try to start file which is at this path /var/www/html/ with name test.js: forever start test.js

But nothing happens. I have globally installed forever. Where am I wrong?

in test.js i have this js code:

var http = require('http');

http.createServer(function (request, response) {
  response.writeHead(200, {'Content-Type': 'text/plain'});
  response.end('testing. . .\n');
}).listen(8124);

console.log('Server running...');

tried this command ps -eaf | grep node and output:
