Can you capture a full startup log with ./nodebb slog?

phenomlab

@pitaj All I get is this

sudonix@vps:~/nodebb$ ./nodebb slog

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
   61 |   <div widget-area="contentbetween"><!-- BEGIN widgets.contentbetween -->{widgets.contentbetween.html}<!-- END widgets.contentbetween --></div>
      |                                                ^^^^^^^^^^^^^^^^^^^^^^ `widgets.contentbetween` could refer to the top-level value `widgets.contentbetween` or the `.widgets.contentbetween` property of the current element, so compiler must emit code for both cases
      | note: Migrate to modern syntax to avoid the ambiguity. This will become an error in the future.

I suggest disabling all custom plugins and themes and see if the issue is still there, then you can reenable one by one to find what's wrong. If it's still not starting up with the base plugins then you will have to debug the startup with some console.logs.

Also modify your config.json to start only a single process and see if that makes a difference.

@baris Thanks. Interestingly, it'll start with node app js ??

I actually disabled everything with ./nodebb reset - exactly the same issue.

I'm happy for this to run in ./nodebb dev but will probably need to execute it as a cron job or something. I can't leave the remote SSH session running indefinitely for obvious reasons.

Can you provide an explanation of what is needed to do this ?

<baris>

If your config.json has "port": [4567, 4568, 4569] then you change it to "port": "4567"

You say you disabled everything but your startup log still shows widgets.contentbetween I don't think that belongs in any of the core themes/plugins.

It doesn't. Just the one port

@baris said in Forum down after restart:

I just enabled the widgets again. The content between notices are from modifications made in either widgets, or using customize. However, they've worked for months (actually since inception) without issues.

@phenomlab don't run in ./nodebb dev long term. It doesn't enforce websocket origin and therefore leaves your users susceptible to cross site websocket hijacking.

phenomlab

@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.

phenomlab

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.

phenomlab

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)

phenomlab

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

PitaJ

@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?

phenomlab

@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

PitaJ

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.

phenomlab

@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)

gotwf

@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.

dunlix

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

phenomlab

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