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
You can kill only one process using the index of the process shown in the forever list command. For example, if you type forever stop 1, only the process with the index 1 will be killed
