test install. I am using PHP 8 from Remi’s repository and other then that it is a pretty basic install which other than the Redis issues does not seem to have any problems. I have made the following changes to Redis config file so it would just be a Unix socket and added the apache user to the redis group. Please not I am using Nginx but the PHP-FPM is running as the apache user. ```auto port 0 unixsocket /var/run/redis/redis.sock unixsocketperm 770 ``` OR ```auto sudo sed -i 's/port 6379/port 0/g' /etc/redis.conf sudo sed -i 's/# unixsocket \/tmp\/redis.sock/unixsocket \/var\/run\/redis\/redis.sock/g' /etc/redis.conf sudo sed -i 's/# unixsocketperm 700/unixsocketperm 770/g' /etc/redis.conf sudo gpasswd -a apache redis ``` Redis looks to be working fine: ```auto sudo -u apache redis-cli -s /var/run/redis/redis.sock redis /var/run/redis/redis.sock> ping PONG ``` The Redis PHP module is enabled: ```auto php -m | grep redis redis ``` Below is what I have added to config.php that cause the error: ```auto 'redis' => array ( 'host' => '/var/run/redis/redis.sock', 'port' => '0', ), 'memcache.distributed' => '\\OC\\Memcache\\Redis', ``` OR ```auto sudo -u apache php /usr/share/nextcloud/occ config:system:set redis host --value="/var/run/redis/redis.sock" sudo -u apache php /usr/share/nextcloud/occ config:system:set redis port --value=0 sudo -u apache php /usr/share/nextcloud/occ config:system:set memcache.distributed --value="\OC\Memcache\Redis" ``` Any suggestion on how else to troubleshoot this? ---

```auto sudo ls -l /var/run/redis/redis.sock srwxrwx---. 1 redis redis 0 Aug 29 06:34 /var/run/redis/redis.sock ``` It is owned by the redis group, but I have added the apache user to this group. `sudo gpasswd -a apache redis` I don’t believe this is a permission issue, as I did check that the apache user can use the redis-cli. ```auto sudo -u apache redis-cli -s /var/run/redis/redis.sock redis /var/run/redis/redis.sock> ping PONG ``` ---

I have identified the problem, this is an SELinux issue. I keep forgetting this is a thing on CentOS. When I disable SELinux (`sudo setenforce 0`) the issue goes away. Now I just have to find sometime to figure out how to set a SELinux policy for this. Any suggestions to same me some googling? Thank you ---

[This](https://github.com/predis/predis/issues/277) could help you to generate a permissive SELinux policy that allows Apache or Nginx to read and write to the Redis unix socket. ---

Sorry about taking so long to reply, I have been busy. The following steps resolved the issue: ```auto sudo setsebool -P daemons_enable_cluster_mode 1 sudo grep 'redis.sock' /var/log/audit/audit.log | audit2allow -M httpd-to-redis-socket sudo semodule -i httpd-to-redis-socket.pp ``` Please note, you will have to get Nextcloud/redis to fail once so that there will be something in your audit.log. This seems to be a known issue in RHEL 8/CentOS 8 which will be address in future releases. In Fedora 34 you only need to complete the following steps to resolve this issue: `sudo setsebool -P daemons_enable_cluster_mode 1` Thank you ---
