Having trouble with clustering

natsbee

Hello,

This is my first foray into using NodeBB as a platform. I have managed to scrimp via trial and error, however I am stumped on this issue.

As pointed out in https://docs.nodebb.org/configuring/scaling/, it mentioned that all I have to do is to specify multiple ports in order to fork several processes to be used by Nginx thereafter.

I don't have any special setup on my config.json (everything is at default), other than the following:

"port": ["4567", "4568", "4569"]

Putting Nginx aside, I would like to get NodeBB up and running with multiple processes first.

However, when starting nodebb, these are the errors that came up:

nodebb@localhost:~/nodebb$ ./nodebb log

Hit Ctrl-C to exit

[cluster] Child Process (14041) has exited (code: 0, signal: null)
[cluster] Child Process (14044) has exited (code: 0, signal: null)

How can I resolve this? Thank you.
Peace~

@natsbee that command only starts showing logs with only a couple lines from before.

You'll want to see what the error is by opening the file logs/output.log directly.

Alternatively, just run ./nodebb dev and then it'll just output the logs in real time.

Hello Julian,

Thank you for the response. I have checked and these are the errors that I have received.

nodebb@localhost:~/nodebb$ ./nodebb dev

Oh, I think I know why. I totally missed the "Configuring Redis if multiple processes was used". I subconsciously thought that Redis section was related to the Database type to be used like TigerEngine.

My bad
