Internal Server Error when enabling APCu or redis

DJ45X · April 4, 2023, 8:55pm

/details]

Nextcloud version (eg, 20.0.5): 26.0.0.11
Operating system and version (eg, Ubuntu 20.04): Debian GNU/Linux 11 (bullseye)
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.56 (Debian)
PHP version (eg, 7.4): PHP 8.2.4 and 8.1

The issue you are facing:
I am trying to enable memcaching using APCu and redis. I followed the docs and ensured to apt install php-apcu and apt install redis-server and did setup redis setup correctly. When I add the lines to config.php:

'memcache.local' => '\OC\Memcache\APCu',
'memcache.distributed' => '\OC\Memcache\Redis',

then systemctl restart apache, I get an Internal Server Error on the webpage.

Is this the first time you’ve seen this error? (Y/N):
yes

Steps to replicate it:

Add the lines above to config.php
run systemctl restart apache2

Regarding this error, see Need help with docker install Nextcloud 26.0.0 .

DJ45X · April 4, 2023, 9:04pm

I’m not running nextcloud in a docker. It’s installed on a Debian VM.

rawtaz · April 4, 2023, 9:04pm

Did you look at/read the thread I suggested? It’s irrelevant whether you run it in Docker or not. No need to assume that this is what we’re talking about just because the other poster happens to run it in Docker.

DJ45X · April 4, 2023, 9:05pm

I’m dumb. I should’ve read lol I complain how people don’t read and here I am not reading. My bad. Give me some time to read through

DJ45X · April 4, 2023, 9:11pm

So I see there was no solution in the thread you shared. I did look into the github and searching through, but so far don’t see anything that’s specific to my issue or related to the DAV error. But this would explain why some of my users are reporting missing files. But that is a separate issue of the internal server error when enabling memcaching

ernolf · April 4, 2023, 9:19pm

You only need one php version and I would always advice, to totally remove all not used and not needed php-versions and modules. as well as any meta-packages. It is a common source of plenty of errors.

did you add where nextcloud have to talk to redis, like this (example):

  'redis' => 
  array (
    'host' => '/run/redis/redis-server.sock',
    'port' => 0,
    'timeout' => 0,
  ),

did you start the redis server?

You can live see what redis does with redis-cli:

redis-cli -s /var/run/redis/redis-server.sock monitor

Here you’ll find the redis-cli manual: https://redis.io/docs/connect/cli/

DJ45X · April 4, 2023, 9:28pm

I only installed 8.1, but when I installed various php modules, 8.2 was automatically installed. If I remove 8.1, nextcloud does not run at all. I’ve only ever been able to get it work with both version installed.

I’ve not yet defined where nextcloud talks to redis, nextcloud docs are a bit obscure to me. However, even when just adding the APCu line, I get the same issue. I will add the necessary info for redis and try again.

DJ45X · April 4, 2023, 9:29pm

So how can I disable DAV? I’ve been looking and don’t see this app anywhere.

rawtaz · April 4, 2023, 9:32pm

I’m not sure you can, it’s one of the core/default apps. One could look into the database or just use occ to see if you can list and then disable that specific app. But I’m not sure if Nextcloud would be happy about it

ernolf · April 4, 2023, 9:47pm

That’s botch. You should solve that.
Normaly by totaly removing php8.2:

First switch everything by hand to the 8.1

for linkgroup in `ls /var/lib/dpkg/alternatives/ | grep -E "ph(ar|p)"`; do update-alternatives --config $linkgroup; done

and when you see, that everything is running well, you can totaly remove the not used php8.2:

sudo apt-get remove --purge php8.2*

Thats crucial, since redis is a server at its own. It needs good fine tuning and you should observe it thorowly at the beginning.

As well, you have to add some lines to the php.ini as described here

DJ45X · April 4, 2023, 10:03pm

Any reason why I would be getting Internal server error when just simply enabling APCu though? I followed the docs here.

ernolf · April 4, 2023, 10:08pm

Since APCu is a php module, it could be caused by version confusion I described above.

Are you using php-fpm?

DJ45X · April 4, 2023, 10:22pm

Yea, I believe that’s what uses PHP 8.2.

Nextcloud’s docs are pretty over-complex so I had to rely on googling install guides and what not and trial and error a lot of it, supplemented by the official docs. I ended up making my own guide to fall back on, but I’m sure it’s also not as reliable since it’s pieced together from other various unofficial sources. I’ve been trying to better understand and tune my server and get it performing at its best.

So I did run that command and this is what was returned:

myUser#  for linkgroup in `ls /var/lib/dpkg/alternatives/ | grep -E "ph(ar|p)"`; do update-alternatives --config $linkgroup; done
There are 3 choices for the alternative phar (providing /usr/bin/phar).

  Selection    Path                   Priority   Status
------------------------------------------------------------
* 0            /usr/bin/phar.default   100       auto mode
  1            /usr/bin/phar.default   100       manual mode
  2            /usr/bin/phar8.1        81        manual mode
  3            /usr/bin/phar8.2        82        manual mode

Press <enter> to keep the current choice[*], or type selection number:

I’m not sure what any part of that command is meant to do. I know enough linux to mostly do what I need to lol

ernolf · April 4, 2023, 10:40pm

Read the man page thoroughly until you understand:

man update-alternatives

In this specific case, you should enter “2”, to select the 8.1 Version to be the one you use.

DJ45X · April 4, 2023, 10:54pm

So I selected 2, then ran apt-get remove --purge php8.1 and it returned:

root@v4:/home/luck# apt-get remove --purge php8.2
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Package 'php8.2' is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Still says php version is 8.2.4

PHP 8.2.4 (cli) (built: Mar 16 2023 14:37:38) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.4, Copyright (c) Zend Technologies
    with Zend OPcache v8.2.4, Copyright (c), by Zend Technologies

Do I need to delete the 8.2 directory from /etc/php?

ernolf · April 4, 2023, 11:12pm

I see only on this 2 lines, that you do lots of things verry chaotic.

In the first line you writh 8.1 but in the echo of the console it is 8.2

I wrote something totally diferent: 8.2*

That one * is a so called wildcard for whatever you want. 8.2 is ONLY for php8.2 and php8.2* is for all packeges where the name begins with php8.2

But you should not yet uninstall, before you tried if everything is running smooth.

ernolf · April 4, 2023, 11:16pm

Excuse me, this was chaos from my side, I wrote it wrong.

So now again, this is the correct command:

sudo apt-get remove --purge php8.2*

DJ45X · April 12, 2023, 1:01am

Some updates:

I’ve managed to get APCu working correctly. It had escaped my mind to do apt install php8.1-apcu instead of apt install php-apcu as the latter installed the 8.2 version, which doesn’t work. After purging all of the php8.2 related packages, I went and reinstalled all the other required php mods using php8.1- and that has worked out well.

I’ve since been working on getting redis working for distributed caching and file locking. So far, I have doubled my performance.

Thank you everyone that has responded as all of your responses have lead me to where I am now. Cheers!
