How to do it…

Following steps will help you to create radosgw user:

1. Make sure that the rgw-node1 is able to access the Ceph cluster:

        # ceph -s -k /var/lib/ceph/radosgw/ceph-rgw.rgw-node1/keyring 
          --name client.rgw.rgw-node1

1. Create a RADOS Gateway user for the S3 access:

      # radosgw-admin user create --uid=pratima 
        --display-name="Pratima Umrao" 
        --email=pratima@cephcookbook.com 
        -k /var/lib/ceph/radosgw/ceph-rgw.rgw-node1/keyring 
        --name client.rgw.rgw-node1

1. The values keys (access_key) and the keys (secret_key) would be required later in this chapter for access validation.
2. To use Ceph object storage with the Swift API, we need to create a Swift subuser on the Ceph RGW:

         # radosgw-admin subuser create --uid=pratima 
           --subuser=pratima:swift --access=full 
           -k /var/lib/ceph/radosgw/ceph-rgw.rgw-node1/keyring 
           --name client.rgw.rgw-node1
