Install CEHP Radosgateway on Proxmox

Proxmox, Ceph

RADOS Gateway is an object storage interface in Ceph. It provides interfaces compatible with OpenStack Swift and Amazon S3.

First create a keyring than generated the keys and added them to the keyring:

root@pve1:~# ceph-authtool --create-keyring /etc/ceph/ceph.client.radosgw.keyring

root@pve1:~# ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.pve1 --gen-key
root@pve1:~# ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.pve2 --gen-key
root@pve1:~# ceph-authtool /etc/ceph/ceph.client.radosgw.keyring -n client.radosgw.pve3 --gen-key

And then I added the proper capabilities and add the keys to the cluster:

root@pve1:~# ceph-authtool -n client.radosgw.pve1 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring
root@pve1:~# ceph-authtool -n client.radosgw.pve2 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring
root@pve1:~# ceph-authtool -n client.radosgw.pve3 --cap osd 'allow rwx' --cap mon 'allow rwx' /etc/ceph/ceph.client.radosgw.keyring

scp /etc/ceph/ceph.client.admin.keyring /etc/ceph/ceph.client.radosgw.keyring pve2:/etc/ceph/
scp /etc/ceph/ceph.client.admin.keyring /etc/ceph/ceph.client.radosgw.keyring pve3:/etc/ceph/

root@pve1:~# ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.pve1 -i /etc/ceph/ceph.client.radosgw.keyring
root@pve1:~# ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.pve2 -i /etc/ceph/ceph.client.radosgw.keyring
root@pve1:~# ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.radosgw.pve3 -i /etc/ceph/ceph.client.radosgw.keyring

If you get the fallofing error: handle_auth_bad_method server allowed_methods [2] but i only support [2]

You Have a problem with your /etc/ceph/ceph.client.admin.keyring file:

sudo ceph --cluster ceph auth get-key client.admin
AQDxnppkhI2ZOBAAJ1VFYV6FvRi8vZyuUYzwZQ==

nano /etc/ceph/ceph.client.admin.keyring
[client.admin]
	key = AQDxnppkhI2ZOBAAJ1VFYV6FvRi8vZyuUYzwZQ==
	caps mds = "allow *"
	caps mgr = "allow *"
	caps mon = "allow *"
	caps osd = "allow *"

Copy to the other nodes:

scp /etc/ceph/ceph.client.admin.keyring /etc/ceph/ceph.client.radosgw.keyring pve2:/etc/ceph/
scp /etc/ceph/ceph.client.admin.keyring /etc/ceph/ceph.client.radosgw.keyring pve3:/etc/ceph/

Copy the rings to the proxmox ClusterFS

root@pve1:~# cp /etc/ceph/ceph.client.radosgw.keyring /etc/pve/priv

Add the following lines to /etc/ceph/ceph.conf:

[client.radosgw.pve1]
        host = pve1
        keyring = /etc/pve/priv/ceph.client.radosgw.keyring
        log file = /var/log/ceph/client.radosgw.$host.log
        rgw_dns_name = s3.devopstales.intra
        rgw_frontends = civetweb port=10.83.110.1:7480

[client.radosgw.pve2]
        host = pve2
        keyring = /etc/pve/priv/ceph.client.radosgw.keyring
        log file = /var/log/ceph/client.radosgw.$host.log
        rgw_dns_name = s3.devopstales.intra
        rgw_frontends = civetweb port=10.83.110.2:7480

[client.radosgw.pve3]
        host = pve3
        keyring = /etc/pve/priv/ceph.client.radosgw.keyring
        log file = /var/log/ceph/client.rados.$host.log
        rgw_dns_name = s3.devopstales.intra
        rgw_frontends = civetweb port=10.83.110.3:7480

Install the pcakages and start the service. If all goes well, RADOSGW will create some default pools for you.
