Transactional file locking error with redis and php-redis installed

Server
1

Hello everybody,

I have the following error in my ownCloud web admin section:

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.

The thing is: I have install both redis-server and php-redis and added the relevant configuration in config.php, as is documented in the documentation, but the error remains. Interestingly, when I change the local cache for APCu to Redis I get an error. Redis is up and running according to service redis-server status. No matter what I try, I can’t get it to work.

Server configuration

Operating system: Debian 9 (Stretch)

Web server: Apache/2.4.25

I think most of the setup use an ip address or a hostname (maybe localhost) to access to redis. If you’re using an unix socket, verify ownCloud (apache) can access to the socket

Hey,

maybe the PHP redis module is also just not loaded even if the php-redis package was installed?

I managed to solve the issue. Turns out I was still using PHP 5 instead of 7. I did have php7-cli installed, which led me to believe I was using the correct version, but I still had to install the php7.0 metapackage. After doing so and disabling PHP5 (a2dismod) and enabling PHP 7 (a2enmod) the issue was resolved.

Thanks for your help! It was due to your suggestions I tried using a port instead of a socket and discovered that the issue must be something more fundamental.
