ownCloud 7 on my CentOS 7 VM kept on complaining that I don’t have access to the config directory. On contrary I had both
/var/www/html/owncloud/data directory set to
drwxr-x---. respectively. Yet the server complained about not having access to the config directory. Here comes the SELinux part. SELinux is by default set to enforce which we want to set to permissive more. It would be better if you create an exception rather than setting it to permissive mode but for now here is how you set up it to permissive mode.
You can check the status of SELinux by running
sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: permissive Mode from config file: enforcing Policy MLS status: enabled Policy deny_unknown status: allowed Max kernel policy version: 28
