CentOs 6.5 using root acount, I have a working Node.js Express app:

root@vps [/home/test/node]# npm start app.js
> test@0.0.1 start /home/test/node
> node ./bin/www app.js

The app can be seen working on the internet browser. I stop the app and try to run it with forever:

root@vps [/home/test/node]# forever start app.js
warn:    --minUptime not set. Defaulting to: 1000ms
warn:    --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
info:    Forever processing file: app.js
root@vps [/home/test/node]#

Throws a couple of warnings that should not be a problem and looks like it should be working but its not showing on the browser, forever list:

root@vps [/home/test/node]# forever list
info:    Forever processes running
data:        uid  command             script forever pid   id logfile                 uptime
data:    [0] OkGm /usr/local/bin/node app.js 32222   32227    /root/.forever/OkGm.log STOPPED
root@vps [/home/test/node]#

If I check OkGm.log:

error: Forever detected script exited with code: 0

Why is the app not working when I run it with forever?

Ok I found out what was happening. I was trying to run:

forever start app.js

When this Express app must be started with:

 forever start ./bin/www

There was no useful info on internet when searching for this by the error log output ("exited with code: 0"), so I hope this answer helps begginers like me in what I think can be an easy mistake to make.
