Redis error with newly installed nextcloud 24.0.2

🚧 Installation
1

Also had the same with previous 24 versions. I do the initial setup in a Linux server installing from command-line (without containers). When I do php occ app:list, I get:

An unhandled exception has been thrown:
RedisException: No such file or directory in /var/www/nextcloud/lib/private/RedisFactory.php:137

Despite the error being: No such file or directory in /var/www/nextcloud/lib/private/RedisFactory.php, this file exists. I did some research and I see that my Redis conf says there should be a redis.sock file on /var/run/redis/ but it does not exist. I have installed redis-server on Debian bullseye with apt-get.

Any idea how can I fix it?

Did you also install the php-redis package?

Afaik a default installation of Redis on Debian is listening on port 6379 at localhost (127.0.0.1:6379)

You can check by entering the following command: ps ax | grep redis

You would then add a section like this to your config.php:

'redis' => [
     'host' => 'localhost',
     'port' => 6379,
],

If you have configured Nextcloud to connect to Redis via Unix Socket, which is the recommended way, you also have to configure Redis accordingly and set the correct permissions:

cp /etc/redis/redis.conf /etc/redis/redis.conf.bak

sed -i "s/port 6379/port 0/" /etc/redis/redis.conf

sed -i s/\#\ unixsocket/\unixsocket/g /etc/redis/redis.conf

sed -i "s/unixsocketperm 700/unixsocketperm 770/" /etc/redis/redis.conf

sed -i "s/# maxclients 10000/maxclients 10240/" /etc/redis/redis.conf

usermod -aG redis www-data

cp /etc/sysctl.conf /etc/sysctl.conf.bak

sed -i '$avm.overcommit_memory = 1' /etc/sysctl.conf

reboot now

Wow, that is great. It worked as charm. Something was wrong in my config most probably. Thanks!

I had the same problem. I updated my Ubuntu from 20.04.4 LTS (focal) up to version 22.04.1 LTS (jammy), afterwards my nextcloud didn’t work and I could not connect to the nextcloud.

journalctl -xe
zeigte Fehler an:
notify_push[827]: Failed to setup redis subscription: Error while running redis query

I solved this problem using the command
apt-get install php-redis

THANK YOU BB77 !!!
