I am deploying two node.js apps on the aws, the two apps are in the paths shown as
/home/ubuntu/nodes/app1/app.js
/home/ubuntu/nodes/app2/app.js
You can use an uid (see here):
$ sudo forever --uid "app1" start app.js
$ sudo forever --uid "app2" start app.js
And to stop:
$ sudo forever stop app1
Update
The --uid option is deprecated.
Now you can use the --pidFile option. Example:
forever start --pidFile /some/path/app1.pid app.js
forever start --pidFile /some/path/app2.pid app.js
And to stop:
forever stop --pidFile /some/path/app1.pid
