|

Either use configure apache to run a rados gateway, or use the built-in
|
|
civetweb server.
|
|
Only one should be run per machine, since it uses a hard-coded port for
|
|
now.
|
|
|
|
For example, to run rgw on all clients::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- rgw:
|
|
|
|
To only run on certain clients::
|
|
|
|
tasks:
|
|
- ceph:
|
|
- rgw: [client.0, client.3]
|
|
|
|
or
|
|
|
|
tasks:
|
|
- ceph:
|
|
- rgw:
|
|
client.0:
|
|
client.3:
|
|
|
|
You can adjust the idle timeout for fastcgi (default is 30 seconds):
|
|
|
|
tasks:
|
|
- ceph:
|
|
- rgw:
|
|
client.0:
|
|
idle_timeout: 90
|
|
|
|
To run radosgw through valgrind:
|
|
|
|
tasks:
|
|
- ceph:
|
|
- rgw:
|
|
client.0:
|
|
valgrind: [--tool=memcheck]
|
|
client.3:
|
|
valgrind: [--tool=memcheck]
|
|
|
|
To use civetweb instead of apache:
|
|
|
|
tasks:
|
|
- ceph:
|
|
- rgw:
|
|
- client.0
|
|
overrides:
|
|
rgw:
|
|
frontend: civetweb
|
|
|
|
Note that without a modified fastcgi module e.g. with the default
|
|
one on CentOS, you must have rgw print continue = false in ceph.conf::
|
|
|
|
tasks:
|
|
- ceph:
|
|
conf:
|
|
global:
|
|
rgw print continue: false
|
|
- rgw: [client.0]
|
|
|
|
To run rgws for multiple regions or zones, describe the regions
|
|
and their zones in a regions section. The endpoints will be
|
|
generated by this task. Each client must have a region, zone,
|
|
and pools assigned in ceph.conf::
|
|
|
|
tasks:
|
|
- install:
|
|
- ceph:
|
|
conf:
|
|
client.0:
|
|
rgw region: foo
|
|
rgw zone: foo-1

|
|
rgw zone root pool: .rgw.zroot.foo
|
|
rgw log meta: true
|
|
rgw log data: true
|
|
client.1:

|

|

|

|
|
rgw zone root pool: .rgw.zroot.bar
|

rgw log meta: true
|

|

client.2:
