Ceph » devops

There is a centos init script in the ceph wip-init-radosgw. It's ready to go, just needs review.

bash -x is set.
ceph-conf is called, ceph (no ceph-common for EL) package is not set as a radosgw dependency.

There is a difference in process owner between Debian and EL.
Debian launches the radosgw as root, EL as apache user, which seems odd based on the Debian startup script (I'm not very efficient with init-function if I'm honest).
This means that whatever path your rgw socket is in should have the correct permission for the apache user.
Is there a particular security risk associated with running the rgw as root?

Gary, ping me anytime if you want more info.

I was puzzled by this so I took a look further:

The -u or --user option for start-stop-daemon do not launch the process as the user specified, it is the role of the -c (--chuid).

The -u option is used to check if the process is already running with a user specified by -u. If this is the case, you will get a nice '<process> already running'.

On Debian, the check is wrong since we launch with user root and check against user www-data. The fix is either:
start-stop-daemon --start -u root -x $RADOSGW -- -n $name #if we want to launch the process as root, or
start-stop-daemon --start -u $user -c $user -x $RADOSGW -- -n $name #if we wan to launch the process as www-data

On CentOS, the check is done by checking if the PID file exists.

The wip-init-radosgw has been updated by removing -x bash option, and by adding ceph as a dependency for the radosgw package. Brnach has also been rebased to master. Will followup on remaining issues in the morning.

I don't think we want ceph to be a dependency for the radosgw package, do we? It should be possible to install separately as a lot of users put it on separate nodes from any other Ceph things.
