Support intro

Installed Redis on server, configured nextcloud to use it, its appears not to be able to detect it.

Nextcloud version _ 24.0.4
Operating system and version Ubuntu 22.04.1 LTS
Apache or nginx version Apache/2.4.54 (Ubuntu) nginx/1.23.1
PHP version 8.1

The issue you are facing:

Redis is installed and working, however NextCloud doesn’t seem to see it:
No memory cache has been configured. To enhance performance, please configure a memcache, if available. Further information can be found in the documentation :arrow_upper_right:.
Is this the first time you’ve seen this error? (Y/N):Y

Steps to replicate it:

  1. Install Redis Server + PHP Modules

  2. Configure nextcloud using:
    ‘filelocking.enabled’ => true,
    ‘memcache.distributed’ => ‘\OC\Memcache\Redis’,
    ‘redis’ =>
    array (
    ‘host’ => ‘127.0.0.1’,
    ‘port’ => 6379,
    ‘timeout’ => 0.0,
    ),

The output of your Nextcloud log in Admin > Logging:

N/A

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

Is your redis server running on a tcp port or a unix socket? Check the config in /etc/redis/redis.conf. In my redis.conf, I have a unix socket:

port 0
unixsocket /var/run/redis/redis-server.sock
unixsocketperm 760

And in my nextcloud config:

‘redis’ =>
array (
‘host’ => ‘/var/run/redis/redis-server.sock’,
‘port’ => 0,
‘timeout’ => 1.5,
‘password’ => ‘secret’,
),

TCP port will also work, but you need the same settings in both files.

Btw, is your trusted_domains array really empty? This is unrelated, but I guess that can cause problems too.
