anyone can please direct me what could have been wrong in here? if I remove this lines in my config

‘filelocking.enabled’ => ‘true’,
‘memcache.locking’ => ‘\OC\Memcache\Redis’,
‘redis’ => array(
‘host’ => ‘localhost’,
‘port’ =>0,
‘timeout’ => 0.0,

everything is loaded except for the error message:

  • Transactional file locking should be configured to use memory-based locking, not the default slow database-based locking. See the [documentation :arrow_upper_right: for more information.



what guide were you using ?

This is obviously wrong, you should consider reading the official ownCloud docs at


after following this one

I end up following this thread.


Okay but even in this post the configuration is different than yours:

the author’s config

'memcache.local' => '\OC\Memcache\APCu',
'memcache.locking' => '\\OC\\Memcache\\Redis',
'filelocking.enabled' => 'true',
'redis' => 
array (
'host' => '/var/run/redis/redis.sock',
'port' => 0,
'timeout' => 0.0,

your config:

‘filelocking.enabled’ => ‘true’,
‘memcache.locking’ => ‘\OC\Memcache\Redis’,
‘redis’ => array(
‘host’ => ‘localhost’,
‘port’ =>0,
‘timeout’ => 0.0,


ahh yes, I change that after I used the original config from the author. SInce I still end up with the same issue and that didn’t resolve my issue and yes I put it back the way it is right now. and comment it since it crashes when I uncomment it.


after reading the docs. I endup with this config, but now it doesn’t load anything just saying it " This site can’t be reached too long to respond"

<?php $CONFIG = array ( 'updatechecker' => false, 'instanceid' => 'oco1d6w9ff9h', 'passwordsalt' => 'nXr0i1+N9nFYzG2PPrhdYF8yWqIpQ8', 'secret' => 'AH3JaEcsN8DavRURbdg9JGtRU+beuWmFScKEM/1mqZNRNsja', 'trusted_domains' => array ( 0 => '', ), 'datadirectory' => '/var/www/html/owncloud/data', 'overwrite.cli.url' => '', 'dbtype' => 'sqlite3', 'version' => '', 'logtimezone' => 'UTC', 'installed' => true, 'memcache.local' => '\OC\Memcache\APCu', 'filelocking.enabled' => true, 'memcache.locking' => '\OC\Memcache\Redis', 'redis' => [ 'host' => 'localhost', 'port' => 6379, 'timeout' => 0.0, ], );



could it be possible that you havn’t installed redis at all?


it’s already installed, I have redis-3.2.12-2.el7.x86_64



i think it might be possible that just installing it isn’t enough. e.g. your initial post had a “Connection refused” which seems that either redis is not listening on the expected port or your system is somehow blocking ownCloud to access the configured port.


I dont have firewalld, nor iptables or selinux running. I as able to solve the connection refused, I check on my logs and saw module being loaded repeatedly. but now with my configuration I am still seeing that warning for

Transactional file locking should be configured to use memory-based locking, not the default slow database-based locking
