@baris thanks. I removed NodeJS and reinstalled it using 14.x version. NodeBB now looks like it starts using the daemon (according to the logs, although if I try nodebb stop it tells me NodeBB is already stopped), and I get 502 bad gateway - but nothing has changed in terms of overall directory structure and nginx config.

So it looks like whilst the original odd message has cleared, it's not starting

My other NodeBB site works fine

PitaJ

@phenomlab could you try deleting your log file and starting with ./nodebb slog again?

phenomlab

@pitaj doesn't seem to do anything other than this

Starting NodeBB with logging output
Hit Ctrl-C to exit
The NodeBB process will continue to run in the background
Use "./nodebb stop" to stop the NodeBB server
tail: cannot open './logs/output.log' for reading: No such file or directory
tail: './logs/output.log' has appeared;  following new file

phenomlab

At this point, I'm totally stumped. The only other option I have available is to create a new instance and attach the current database to that to see if this resolves the issue or not.

Failing that, I'm at a total loss here.

@PitaJ @baris I've been looking into this more, and but when I start NodeBB I get this message

The problem is, the port isn't actively being used anywhere. I have another NodeBB instance running on 4568, but that's it.

Any thoughts ?

Thanks

PitaJ

@phenomlab I don't know what to tell you. It's not lying about the address being in use.

Does it work if you run node app? If not, it's definitely a rogue process left running on that port.

phenomlab

@pitaj thanks. Found the rogue process, and now I'm stuck with this.

sudonix@vps:~/nodebb$ ./nodebb start && ./nodebb log

  "./nodebb stop" to stop the NodeBB server

So it looks like the process spawns and then immediately crashes. Trouble is I don't know where. It even does this with all plugins disabled.

Yes

Does it still work with daemon:false or does that no longer help?

phenomlab

@pitaj that works fine

The only issue of course is that when performing a restart from the ACP I have to kill the process and restart it manually

PitaJ

@phenomlab it must be something to do with the daemon stuff.

Can you try adding console.logs through there to try and find where the script stops executing for you?

phenomlab

@pitaj I found this discussion from a while ago and it seems to be my exact issue. Sadly, there never was a fix provided

phenomlab

Interestingly, ./nodebb slog works (but doesn't survive a rebuild and restart) fine, but I still need to leave this running as it isn't a daemon

PitaJ

@phenomlab ./nodebb slog just runs ./nodebb start then shows the log with tail. Nothing fancy. When you quit the command, you're just exiting tail, NodeBB isn't stopped.

The "production" equivalent of ./nodebb dev is node app. There are many ways you can set it up to run as a daemon. For instance, setting up a systemd service.

@phenomlab Yo mon! Ye' be having just way too much fun!

Which is probably the way to go if you're using a systemd based distro

Running NodeBB - NodeBB Documentation

Documentation portal for NodeBB Forum Software

(docs.nodebb.org)

Rock on!

phenomlab

@pitaj @gotwf thanks guys. Much appreciated. I'll go down this route - probably using systemd to create a service.

phenomlab

@PitaJ interestingly, after starting NodeBB using ./NodeBB slog, if I then execute ./NodeBB stop I get

NodeBB is already stopped.

So think it's correct to say that as far as the daemon is concerned, it's not running even though it actually is.

PitaJ

@phenomlab glad that'll work for you.

Would you mind participating in some more debug for this down the line? There's an alternative package for starting the daemon that I'm wondering might work for you.
