I'm confusing now. Sounds like that radosgw-admin is a daemon or service ? Is there any document for study ?
I set admin_socket in ceph.conf and restart radosgw daemon. But there still has no asock of radosgw tho. My ceph.conf looks like : [global] fsid = 6e05675c-f545-4d88-9784-ea56ceda750e mon_initial_members = s01, s02, s03 mon_host = 192.168.2.61,192.168.2.62,192.168.2.63 auth_supported = cephx osd_journal_size = 1024 filestore_xattr_use_omap = true admin_socket = /var/run/ceph [client.radosgw.gateway] host = p01 keyring = /etc/ceph/keyring.radosgw.gateway rgw_socket_path = /tmp/radosgw.sock log_file = /var/log/ceph/radosgw.log rgw_thread_pool_size = 200 rgw_cache_enabled = false +Hugo Kuo+ (+886) 935004793 2013/9/12 Yehuda Sadeh <[email protected]> > On Thu, Sep 12, 2013 at 4:11 AM, Fuchs, Andreas (SwissTXT) > <[email protected]> wrote: > > Hi Yehuda > > > > I run a similar setup like Hugo > > > > Radosgw is on a dedicated host, no OSD's on the gw.
