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 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
forever list
forever stop 1
