Solved Forum down after restart


  • @pitaj Thanks. I read through the associated post you sent, and yes, it does sound like my particular issue but I am not seeing the need for a swap file on a system as large as mine.

    The other NodeBB instance I have running is absolutely fine.


  • I'm curious to understand what exactly that error is I'm encountering and why NodeBB chooses to crash out at that point. Perhaps if I understood the reasoning, working towards a fix might be easier ?

    Thanks for all the support thus far guys. Really appreciated.


  • Not sure I can even run in ./NodeBB dev short term as this will require an open connection to my server which isn't permitted (the open session will time out meaning NodeBB will stop)


  • What is the difference between ./NodeBB start and ./NodeBB dev ? Why does one work and not the other ?


  • @phenomlab I don't know what the error is, nor do I know why it's crashing there. The log looks incomplete but I don't know why that is either.

    I'm as confused as you are. Searching for that be sendmail error results in nothing useful to me. I don't even know why sendmail would be involved in startup.

    Maybe you're seeing outdated logs? Can you try renaming logs/output.log to something else and doing ./nodebb slog again?

    Have you tried chowning the files to the user you're running as?


  • @pitaj very odd. I deleted the log file and it was regenerated with ./NodeBB start but it contains no entries and NodeBB still won't start

    What permissions should be assigned to folders and files ? 755 and 664 ? The username is already correct as far as I can see.

    Thanks


  • So it works of you run with node app, right? No errors when you run that?

    Have you double checked to make sure all node processes are killed?

    If you're running with a single port, you might try using screen or tmux to run with node app as a stopgap. That essentially the same as running with ./nodebb dev except all security checks stay in place.

    You could also try setting "daemon": false in config.json and try ./nodebb start with that.

    As for permissions, yeah make sure all files are owned by nodebb:nodebb and have 755 permissions.


  • @pitaj a bit of a positive development. I've added "daemon": false into config.json and have successfully started NodeBB. However, this then runs as a session which isn't great, but I can at least close the terminal window and the process continues to run without dying.

    For now, this should be enough to keep the forum running until I figure out exactly why it won't start as a daemon. I noticed there's an upgrade to core so I'll try that also (1.18.3)


  • @phenomlab Quite the saga here. Bummer for sure, especially on a production box. What prompted the restart? Perchance did that follow any system updates? If so, I presume you're hip enough to have already considered such but just a thought.

    Royal pita but maybe time to cut your losses, export the db whilst you can, spin up a new vm and go from there? Tough call.

  • GNU/Linux Gamers

    What if you set up a new NodeBB from scratch but use the same database in your config and then move the uploads folder to the new one too?
    Meaning all plugins and stuff like that will be nonexistant and it will be stock nodeBB installation. Then, you can reinstall your plugins one by one and your custom things too to see what exactly is causing this problem

    Also i just read the latest post that you have (somewhat) fixed the issue but if your feeling up to a tedious job (lol) then try my solution


  • @baris @PitaJ just tried an upgrade, and got this

  • @baris thanks

  • Starting with "daemon": false works, but I'd rather use the daemon

  • NodeBB Admin

    What version of node & npm are you using now?


  • @baris Versions below
    Node.js v16.10.0.
    npm --version 6.14.15

  • NodeBB Admin

    Can you try latest node 14.x, we don't official support 16 yet.


  • @baris ok. How can I downgrade ?
