Can not run nodebb

[mohammadhassan]

Hi guys, I installed NodeBB on debian 9 with redis database. I installed NodeBB and left all the options as default. I started Nodebb by ./nodebb start command but when I visit my forum at http://127.0.0.1:4567/ , It just connects and disconnects. I used ./nodebb log and got this:

7/11 13:01:30 [15339] - error:  Error: listen EADDRINUSE 0.0.0.0:4567

3 restarts in 10 seconds, most likely an error on startup. Halting.

The port 4567 is away in use, possibly do to nodebb already running. Google "how to kill process on port" and you should be able to kill whatever process is already running.
