Unable to start node application since installing PM2

Question

I have installed PM2 to keep my node application running. (https://github.com/Unitech/pm2)

It works great, however...

Since installing and running my app with it

pm2 start app.js pm2 stop app

I am no longer able to run my app using

node app.js

Instead I get the following error:

domain.js:66
    throw er;
          ^
Error: listen EADDRINUSE
    at errnoException (net.js:770:11)
    at Server._listen2 (net.js:910:14)
    at listen (net.js:932:10)
    at Server.listen (net.js:998:5)
    at Function.app.listen (/home/ssp/node_modules/express/lib/application.js:535:24)
    at Object.<anonymous> (/home/ssp/app.dev.js:22:5)
    at Module._compile (module.js:449:26)
    at Object.Module._extensions..js (module.js:467:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)

This error usually happens when you try to run the same thing twice.

However app.js is not running. I have stopped it in PM2. And when I type

ps aux | grep node

To check if it is still there, it is not.

Uninstalling PM2 does not seem to fix this. Any ideas what is going on?

What does pm2 list say? is it still keeping the port open "for convenience"? — Mike 'Pomax' Kamermans

Since pm2 overwrites the process title, your app won't show up using the ps command you mention; either grep for app (instead of node) or use pm2 list instead, as Mike suggests. — robertklep

Overall this means that you have a process running on the same port, you can kill it using:

sudo kill $(sudo lsof -t -i:8080)

just replace 8080 with your server port

If you get this problem do a :

pm2 kill

(it kills pm2 and the port is freed)

This bug is really strange and impact only v0.10.x node versions.

I recommend you to use the node v0.11.10
