It works. Thank you for your time (Srinivas and Ben).
Supplement:
client.radosgw.gateway-1 and client.radosgw.gateway-2 should only share
the same ceph pools.
A keyring must be created for both client.radosgw.gateway-1 and
client.radosgw.gateway-2.
thx

It works fine. The federated config reference is not related to
running multiple instances on the same zone.
Just set up 2 radosgws give each instance the exact same
configuration. (I use different client names in ceph.conf, but i bet
it would work even if the client names were identical)
Official documentation on this very common use case would be a good
idea, i also figured this out on my own.

Hello Srinivas,
Yes, we can use Haproxy as a frontend. But the precondition is multi
RadosGW instances sharing
the *SAME CEPH POOLS* are running. I only want the master zone keep
one copy of all data. I want
to access the data through *ANY *radosgw instance.
And it said in http://docs.ceph.com/docs/master/radosgw/federated-config/
"zones may have more than one Ceph Object Gateway instance per zone.".
So I need the *official way*
to set up these radosgw instances.
thx

Hi Joseph,
You can try haproxy as proxy for load balancing and failover.

*Subject:* [ceph-users] How to run multiple RadosGW instances
under the same zone
Hello,
How to run multiple RadosGW instances under the same zone?
Assume there are two hosts HOST_1 and HOST2. I want to run
two RadosGW instances on these two hosts for my zone ZONE_MULI.
So, when one of the radosgw instance is down, I can still access the zone.
There are some questions:
1. How many ceph users should I create?
2. How many rados users should I create?
3. How to set ZONE_MULI's access_key/secret_key?
4. How to set the 'host' section in the ceph conf file for these two
radosgw instances?
5. How to start the instances?
# radosgw --cluster My_Cluster -n ?_which_rados_user_?
I readhttp://docs.ceph.com/docs/master/radosgw/federated-config/, but
there seems no explanation.
Your answer is appreciated!
thx
Joseph
