Unable to get redis cache running on debian 10 based Nextcloud instance

With the socket on 770 I get this spamming again.

Changing it to 777 stops that, but instead I get this.

That should go away when you add redis to www-data group.

root@nextcloud:/var/www/nextcloud# adduser redis www-data
Adding user `redis' to group `www-data' ...
Adding user redis to group www-data
Done.
root@nextcloud:/var/www/nextcloud# systemctl restart redis
root@nextcloud:/var/www/nextcloud# systemctl restart apache2
# edit conf to change permission to 770 again
root@nextcloud:/var/www/nextcloud# nano /etc/redis/redis.conf 
root@nextcloud:/var/www/nextcloud# systemctl restart redis

and back to the spamming permission denied.

Go the other way and add www-data to the redis group instead?

Nothing.

I'm at a real loss as to WTF is going on here.

Since he's back... @jospoortvliet any hints on where to look?

Honestly it can be quite a PITA. A solution might be to kind'a start from scratch and follow the how-to from techrepublic - I helped Jack write that, we had also permission errors. The group thing was a big part of the solution. Note you need to restart stuff after changing groups etc, maybe a horrible reboot can help.

And yeah, I was looking here. I don't see any obvious issues...

I'll poke at this shortly.

I've never had a problem enabling this on a CentOS or Fedora system. I do not use Ubuntu anywhere. This one was Debian because supposedly the OCR plugin needs a package that is not available on Fedora.

Possibly unrelated, but I was having problems getting a new instance setup on Ubuntu. Redis wasn't working there either. I bailed almost immediately as I didn't have time to mess with it. Installed it on Fedora, and it everything seems to be working as expected.

ok got it.

I had to keep the socket permission at 770 instead of 700. I can fine tune that later when the system is not in use.

This is my config.php

  'filelocking.enabled' => true,
  'memcache.local' => '\\OC\\Memcache\\Redis',
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'redis' =>
    array (
      'host' => '/var/run/redis/redis-server.sock',
      'port' => 0,
      'timeout' => 0,
      'password' => '',
      'dbindex' => 0,
    ),
