cron.php is not running scheduled tasks

cron.php is not running scheduled tasks

Good morning.

I'm using Moodle 3.4+ (Build: 20171208).

I set up crontab on my server to run admin/cli/cron.php every minute and save logs to file. Cron is running cron.php correctly, but problem is that script is not running any of scheduled tasks. Output from cron.php looks like this:

"Server Time: Tue, 26 Dec 2017 19:37:51 +0100"

and that's all. Running script directly from command line via SSH gives exactly the same result. 

When I naviage into "Administration > Site administration > Server > Scheduled Tasks" I see that for all tasks last execution time is "never", until I explictly run one of them using "Run now" link above.

Regards.

Just to check... what is the command line you are using?

I don't understand. I'm just logging in to my server via SSH and run for example "php admin/cli/cron.php".

That was what I was asking. It is, of course, the correct command.

Switch on Debugging and try again...

In your first posting ...

'and save logs to file.' ... which suggest one is not running

php admin/cli/cron.php all by itself (which is what you tested).

What does the command look like in cron tab with the 'and save logs to file' look like?

**Something** like this:

/usr/bin/php /srv/www/moodle/admin/cli/cron.php >/tmp/moodle_cron.log 2>&1

IF that's true, then one could watch the moodle_cron.log file in realtime ...

tail -f /tmp/moodle_cron.log

You substitute things above to suit your setup.

What do you mean, "you got this..."?

What exactly did you do and what happened (when you ran the cron command on the command line)?

I've run "php admin/cli/cron.php" command on my server and it has printed on console what I sent in previous post (https://pastebin.com/Vy8L2fVV)

Moodle did not produce that output... so something else is going on. Have you asked your host's support about this? I suspect something unusual with your local cron setup.

...but (unless I'm missing something) he didn't say that he got that message.

Thanks, but what can I do for that? I switched to database locks in my config.php and now I get this:

Fatal error: Call to a member function real_escape_string() on null in /usr/home/zseinstalacje.usermd.net/public_html/lib/dml/mysqli_native_moodle_database.php on line 1083

Ok, I solved problem.  "php" from command line was using old php 5.6 instead of 7.1


Thanks for help.
