I have added into redis.conf :
unixsocket /var/run/redis/redis-server.sock
unixsocketperm 770
and do :
firewall-cmd --add-port=6379/tcp --permanent
I have test lot of parameters into /var/www/nextcloud/config/config.php For Redis. I don’t know which one to use.
This don’t works :
'filelocking.enabled' => 'true',
'memcache.local' => '\\OC\\Memcache\\APCu',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => array (
'host' => '/var/run/redis/redis-server.sock',
'port' => '0',
'timeout' => '0.0',
),
'memcache.distributed' => '\\OC\\Memcache\\Redis',
This works on 127.0.0.1 (not www…abc…com) and after type redis-server into terminal :
'memcache.local' => '\\OC\\Memcache\\APCu',
'filelocking.enabled' => 'true',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'redis' => array (
'host' => 'localhost',
'port' => 6379,
),
'memcache.distributed' => '\\OC\\Memcache\\Redis',
