Procedure 8.3. Instructions

1. Log in to serverc as the admin user. Create a realm called prod and set it as the default. Create a master zone group called us-west with the endpoint set to http://serverc:8080. Set the zone group as the default.

   1. Log in to serverc as the admin user and use sudo to run the cephadm shell.

      [student@workstation ~]$ ssh admin@serverc
      [admin@serverc ~]$ sudo cephadm shell
      [ceph: root@serverc /]#

   2. Create a realm called prod and set it as the default.

      [ceph: root@serverc /]# radosgw-admin realm create --rgw-realm=prod --default

   3. Create a master zone group called us-west.

      [ceph: root@serverc /]# radosgw-admin zonegroup create --rgw-zonegroup=us-west \
        --endpoints=http://serverc:8080 --master --default

2. Create a master zone called us-west-1 and set the endpoint to http://serverc:8080. Set the zone as the default. Use admin as the access key and secure as the secret key.

   [ceph: root@serverc /]# radosgw-admin zone create --rgw-zonegroup=us-west \
     --rgw-zone=us-west-1 --endpoints=http://serverc:8080 --master \
     --access-key=admin --secret=secure --default

3. Create a system user called admin.user with admin as the access key and secure as the secret key.

   [ceph: root@serverc /]# radosgw-admin user create --uid="admin.user" --system \
     --display-name="Admin User" --access-key=admin --secret=secure

4. Commit the configuration. Save the period ID value in the /home/admin/period-id.txt file on the serverc node. Do not include quotes, double quotes, or characters other than the period ID in UUID format.

   [ceph: root@serverc /]# radosgw-admin period update --commit
   [ceph: root@serverc /]# radosgw-admin period get-current
   {
       "current_period": "aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeeee"
   }
   [ceph: root@serverc /]# exit
   [admin@serverc ~]$ cat /home/admin/period-id.txt
   aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeeee

5. Deploy a RADOS Gateway service called prod-object with two instances running on port 8080, one on the serverc node and the second on the servere node.

   [admin@serverc ~]$ sudo cephadm shell
   [ceph: root@serverc /]# ceph orch apply rgw prod-object --realm=prod \
     --zone=us-west-1 --port 8080 \
     --placement="2 serverc.lab.example.com servere.lab.example.com"
