Virtualmin

Looks like some kind of PHP problem.

https://courses.goperl.com → 503 Service Unavailable

Restart httpd did not resolve.

Disable / Re-enable FPM did not resolve either.

Update 3:

check config shows this error:

Virtualmin could not work out the default IPv6 address for virtual servers on your system. You will need to update either the Network interface for virtual addresses or Default virtual server IP address fields on the module configuration page.

That is because I completely disabled IP6 on the modem. But, not sure if that is causing the PHP problem!

Update 4:

Reboot fixed it!

But how could I have resolved it without rebooting?

Cannot afford to reboot a production server; Though this one is particular is in transition-to-production mode!

6

Update 5:

Well, that was short lived.

Error slightly changed …

Unable to upgrade Moodle (PHP) on courses.goperl.com. Additionally, I am getting that SSL error…

Upgrading Moodle to version 3.11.5 ..
.. failed dependencies : PHP version 7.2 or later is required, but this virtual server is using version 7.3

Machine / virtual server has PHP FPM 7.5 installed/enabled.

7

This Update 5: is it an error generated by Moodle or by the Virtualmin update script process?

8

Virtualmin update scripts

9

Change to version 7.4 and run the update script again. If successful and you still need 7.5 then change again from 7.4 to 7.5

10

OS is Rocky Linux and there is no other PHP (FPM) version than 7.4.19.

Yes, I have already tried disabling/re-enabling multiple times.

11

That seems like a bug. I don’t understand where the 7.3 PHP version is coming from.

I’ll ask @Jamie or @Ilia to have a look, as I don’t understand what the version comparison in the moodle script installer is supposed to be doing (I’m looking at the code and what you’re seeing doesn’t make sense to me!).

12

If you SSH in and run virtualmin check-config , what PHP versions does it report?

13

The following PHP versions are available : 7.4.19 (/bin/php-cgi)

The following PHP-FPM versions are available on this system : 7.4.19 (php-fpm)

14

Surprising that it would report an issue with PHP 7.3 then.

Did you perhaps recently upgrade the PHP version?
