Hello all, I recently updated the packages on my server, among the updates was apache2 which was updated to version 2.4.29 (I use the PPA for Apache 2.x : Ondřej Surý ).
After the update, all services (nginx, apache2, php8.0-fpm, php7.4-fpm ...) were active. For good measure, I restarted all these services, and again they started correctly and were active without any errors.
However,
all of my websites were giving 500 internal server errors.
Inspecting the system logs (/var/log/syslog, /var/log/nginx/error.log, /var/log/apache2/error.log)
I didn't see any errors, however when inspecting the logs for
my single websites, I was seeing this error on all of them:
AH10292: Invalid proxy UDS filename
(proxy:unix:///var/www/vhosts/system/mydomain.com/php-fpm.sock|fcgi://127.0.0.1:9000/var/www/vhosts/mydomain.com/httpdocs/wp-login.php)
The
relative php-fpm.sock files do exist in
the related paths, and have correct permissions, and were
working fine until before the package upgrade.
I stopped services, uninstalled the apache2 package, removed the ppa:ondrej/apache2 repository, and then reinstalled apache2, which is now at version 2.4.41, and all my websites are back up again.
I use Plesk to help manage my webserver and websites. The system is Ubuntu 20.04.3 LTS, architecture x86_64, Plesk is Plesk Obsidian 18.0.38 Update #2, last updated on Sept 15, 2021 02:19 AM.
Other pleskians had the same problem, as can be seen on this thread: https://talk.plesk.com/threads/all-domains-apache2-error-500.362208/ .
I created an issue on Ondrej Sury's github repo: https://github.com/oerdnj/deb.sury.org/issues/1643
Ondrej answered suggesting to open a ticket on the Apache upstream, stating that there haven't been any updates to the packaging.
Is there perhaps an already known bug that might be causing this? Or should a bug report be opened?
Kind regards,
John D'Orazio
