Setup the Flarum scheduler using cron

IanM

Gatsu I already replied to the same question in the FoF/sitemap discussion

datitisev

Gatsu The cron command that runs php flarum schedule:run should always run. That command does not determine how often the scheduled tasks run - it simply checks if a scheduled task should be run.

For fof/sitemap, the cron job is the same. You just change the interval in the settings modal of the extension.

Gatsu

datitisev Sorry but I did not understand how to proceed.
I have the possibility to use the cron via the cPanel, but the problem is that I have not understood what I have to write in command.
I understand that the command is generic, so just indicate "flarum" and not the extensions individually.
What I didn't understand is: what is the command to send via cPanel? (I have attached the screenshot above)
I would like to start the cron 1 time per day.
Thanks for your patience and availability.

IanM

Gatsu I would like to start the cron 1 time per day.

As in the OP, the cron should run * * * * * - every minute, every day. The command is listed.

* * * * * cd /path-to-your-project && php flarum schedule:run >> /dev/null 2>&1

then set the frequency from the settings modal

Gatsu

IanM Thank you. I tried this but I got this error

-bash: CHANGELOG.md: command not found

datitisev

Gatsu The * isn't part of the command. That's the frequency of the command. The command itself should only contain cd /path-to-your-project && php flarum schedule:run >> /dev/null 2>&1.

Gatsu

datitisev Thank you very much!

I have vesta control panel similar to cpanel running on my vps
Do I still need to install cron? I think cron is already installed and running on my server as I can see it in my panel

So in this case should I just add this line?
php flarum schedule:run >> /dev/null 2>&1

datitisev

HD3D That looks like cron, yeah. You'll need the cd part as well so the command is executed in the proper directory.

HD3D

datitisev What I can't understand is.. Do I need to run cd command from my vesta control panel or from SSH?

And do I need to run $ crontab -e command first or simply run cd /path-to-your-project && php flarum schedule:run >> /dev/null 2>&1 ?

datitisev

HD3D crontab -e opens the list of scheduled cron jobs in an editor. What you are using is an alternative to that.

The cd command needs to be included in that command - not run through SSH. That tells it to use the flarum file in your website's root, otherwise I don't know what directory it'd run it in.

HD3D

datitisev Ok, I think I have setup the cron job
I'm getting this message when I run php flarum schedule:run
Running scheduled command: '/usr/bin/php7.2' 'flarum' drafts:publish > '/dev/null' 2>&1

Does it mean my cron for flarum is running correctly?

datitisev

HD3D I think so, yeah. When you say "when I run ...", are you running it manually or did you mean the output from the cron job? There's no point in running it manually as it constantly runs with the cron job.

The cron job and the command are separate. The cron job simply executes the command at the specified intervals. The command that is being run, in this case php flarum schedule:run does not know of said interval.

Hi, when I run php flarum schedule:run
I got this
No scheduled commands are ready to run.

Is it normal?

clarkwinkelmann

Gatsu yes it's normal. schedule:run runs every minute. Everytime it runs, it checks if a command has been scheduled for that particular minute. Most of the time there will be no commands ready to run.

If there's a command scheduled say, every five minutes, by Flarum, 4 times out of 5 you'll see " No scheduled commands are ready to run." and 1 time out of 5 you'll see "running command [...]"

ctml

How does the scheduler behave if it's missed? Lets say I want to run it every 30 minutes as opposed to every minute, is it doable, and will the jobs queue up and run together on the next cron execution or does the scheduler treat them as being past and assume they were executed?

clarkwinkelmann

ctml as far as I know, the scheduler itself cannot catch back on missed tasks.

You run the scheduler script every minute.

Then that script takes care of checking which of the tasks need to run at that particular minute.

If you want to change the schedule of a task, you need to do that at the task registration level. Most extensions allow you to choose the task schedule from the UI.

If you don't run the scheduler every minute, I'm pretty sure any job that was supposed to run at that exact minute will never run.

FoF Drafts publishes the topic even if cron starts every 30 minutes.

IanM path-to-your-project

This path can be the Flarum folder or must be a specific file with some code?

luceos

enricodx Thats the full directory where flarum is installed.

enricodx

luceos I'm trying to create a cron-job with this site https://cron-job.org
But I can't set a command, I must set a file to recall. The question is: what kind of file should it be? And what should I put inside of this file to set the Flarum scheduler properly?
