[cluster] Child Process (1163) has exited (code: 0, signal: null)

Anyone can help me?

You probably already have a nodebb process already running.

To piggyback on @PitaJ's reply, take a look at what is running with ps aux | grep node

You can probably use kill to terminate it, if ./nodebb stop won't work.

@julian @PitaJ this is my result after that I have do fir "./nodebb stop" and after "ps aux | grep node" in Centos:

I do "vagrant up" to start a centos machine.
