When checking out the setup for our OwnCloud system it came up with a few cautionary problems that needed to be resolved.
The problems related to environment variables and file locking.
php does not seem to be setup properly to query system environment variables. The test with getenv(“PATH”) only returns an empty response. Please check the installation documentation ↗ for php configuration notes and the php configuration of your server, especially when using php-fpm.
Transactional file locking is using the database as locking backend, for best performance it’s advised to configure a memcache for locking. See the documentation ↗ for more information.
