‘admin’ -> ‘Generate Config Report’ -> ‘Download ownCloud config report’
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

ATTENTION: Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.

remove all host names, passwords, usernames, salts and other credentials before posting.

This isn’t an ownCloud issue, you should ask the package maintainer for this. I guess they decided to stop creating oC packages for CentOS 6.

And who would that be?
I’m looking at https://download.owncloud.org/download/repositories/stable/owncloud/index.html and I see only CentOS 7 represented.

I’m not on CentOS and would never install ownCloud from an OS repo.

Usually the maintainers of a package are mentioned within the package, with e-mail address. So I would try to contact them, requesting a package for CentOS 6. But I’m afraid you wont have luck. It’s simply too old.
