The issue you are facing:
This is a small personal server with about 5 people using it.
I was previously only using APCu for memory cache (php8.2-apcu and php-apcu).
I am now trying to enable redis (redis-server 5:7.0.12-1) for memcache.locking and memcache.distributed on unixsocket /var/run/redis/redis-server.sock on port 0 following the nextcloud documentation. However when I set all this up I am still getting a warning on the admin overview page for “The database is used for transactional file locking. To enhance performance, please configure memcache”. Im not sure if redis is actually working for nextcloud. It does seem to be running on my system just fine.
I can ping the redis socket as the www-data user:
user# sudo -u www-data redis-cli -s /var/run/redis/redis-server.sock ping
PONG
or (not really sure if /var/run or just /run matters)
user# sudo -u www-data redis-cli -s /run/redis/redis-server.sock ping
PONG
so it seems like everything is set up properly. The problem looks similar to this post here:
but I am not using SELinux or Centos
but when i try to monitor redis I do get an interesting error
root# redis-cli monitor
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Redis.conf and redis-server.log both indicate they are using port 0 not 6379 like redis-cli is.
Is this the first time you’ve seen this error? Y:
Steps to replicate it:
- Install nextcloud mariadb-server redis-server php-apcu
- configure for operation over unixsocket per nextcloud documentation
- view admin overview page
