Hi,
I have read through some documents about authentication and user management
about ceph, everything works fine with me, I can create
a user and play with the keys and caps of that user. But I cannot find where
those keys or capabilities stored, obviously, I can
export those info to a file but where are they if I don't export them out?
Looks like these information (keys and caps) of the user is stored in memory?
but I still can list them out after rebooting my
machine. Or these info are persisted in some type of DB I didn't aware?
Can anyone help me out?
Authentication keys and caps are kept by the monitor in its store,
either a leveldb or a rocksdb, in its data directory.
The monitor's data directory are, by default, in
/var/lib/ceph/mon/ceph-X, with X being the monitor's id. The store is
within that directory, named `store.db`.
The store in not in human-readable format, but you can use
ceph-kvstore-tool to walk the keys if you want. Please note that, should
you want to do this, the monitor must be shutdown first.
