In,
sudo -u www-data /usr/bin/php /var/www/moodle/public/admin/cli/upgrade.php
public/ entfernen, d.h.
sudo -u www-data /usr/bin/php /var/www/moodle/admin/cli/upgrade.php

Das haengt mit der neuen Verzeichnisstruktur zusammen. Es wird laufend im engl. Installing and upgrading help forum diskutiert. Genauere Detail sind unter https://docs.moodle.org/501/en/Upgrading insbes. https://docs.moodle.org/501/en/Upgrading#Code_directories_restructure zu finden.

Perhaps you know the OP's hosting better, you have a direct line, I heard. My point is, trying to run 79 Moodle sites doing roughly the same thing (test?) without true root shell access, not chroot, will be less fun than the OP imagines.

 

"Performance and scalability" is out of bounds anyway, we are here in the Installing and upgrading help forum, not in Hardware and performance.

 

Had a second look at those text files that are being shared, I see only a table of content. The OP might want to look at Installation quick guide, Installing Moodle, Upgrading, etc. for examples.

 

P.S. The mod edited my previous response on my request. I made a typo in it, which said exactly the opposite of I wanted to say!

Aren't there _managed_ servers where the hosting provider installs all the system software and a "panel" on top a native (VPS or dedicated) server and the customer manages his (web) applications?

About the performance and scalability: That is up to the OP. If these are "test" sites, likely that they are not all active at the same time. Yes, the database server will suffer, if you leave databases there, even if they are not being used. All that were not in the questions. I usually don't answer questions that were not raised - unless, yes, I see a serious danger. I don't consider scalability a danger. The OP, who is running so many Moodle sites that long, 15 1/2 years(!), knows the load.

 

That reminds me, if the OP has started talking Shell 15 years ago, he would be very fluent by now.

Don't worry about the "Schedules tab". It was there all the time! Not a place I go often and overlooked it. I think a screenshot would have helped.
