Use Ceph-RGW

This topic describes how to configure Ceph Rados Gateway (RGW) as the backend for the Object Storage Gateway (OSG).


  • Successful completion of all the install sections prior to this section.
  • The UFS must be registered and enabled.
  • A Ceph storage cluster is available.
  • The ceph-radosgw service has been installed (on the UFS or any other host) and configured to use the Ceph storage cluster. recommends using civetweb with ceph-radosgw service. is a lightweight web server and is included in the ceph-radosgw installation. It is relatively easier to install and configure than the alternative option – a combination of Apache and Fastcgi modules.

For more information on Ceph-RGW, see the Ceph-RGW documentation.

Configure Ceph-RGW object storage

You must execute the steps below as a administrator.

Configure ceph-rgw as the storage provider using the euctl command:

euctl objectstorage.providerclient=ceph-rgw

Configure objectstorage.s3provider.s3endpoint to the ip:port of the host running the ceph-radosgw service:

Depending on the front end web server used by ceph-radosgw service, the default port is 80 for apache and 7480 for civetweb.

euctl objectstorage.s3provider.s3endpoint=<radosgw-host-ip>:<radosgw-webserver-port>

Configure objectstorage.s3provider.s3accesskey and objectstorage.s3provider.s3secretkey with the radosgw user credentials:

euctl objectstorage.s3provider.s3accesskey=<radosgw-user-accesskey>
euctl objectstorage.s3provider.s3secretkey=<radosgw-user-secretkey>

The Ceph-RGW backend and OSG are now ready for production.
