Re: radosgw manual deployment

Hi,

I checked our environment (Nautilus) where I enabled the RGW dashboard integration. Please note that we don't use RGW ourselves heavily and I don't have access to our customer's RGWs, so this might look differently for an actual prod environment. Anyway, to get it up and running it could help. Here is the ceph.conf excerpt:


[client.rgw.rgwhost01]
host = rgwhost01.example.com
rgw_dns_name = rgwhost01.example.com
rgw_frontends = civetweb port=7480


And this is my dashboard config:

---snip---
ceph dashboard get-rgw-api-host
rgwhost01.example.com

ceph dashboard get-rgw-api-port
7480

ceph dashboard get-rgw-api-scheme
http

ceph dashboard get-rgw-api-ssl-verify
False

ceph dashboard get-rgw-api-access-key
<ACCESS_KEY>

ceph dashboard get-rgw-api-secret-key
<SECRET_KEY>

ceph dashboard get-rgw-api-admin-resource
admin

radosgw-admin user list
[
    "admin",
    "eblock"
]
---snip---

Note that the admin user has the "--system" flag. Also worth noting that it only worked when host, rgw_dns_name and get-rgw-api-host were identical. I can't tell what role the rgw_dns_name plays in all that, though. But this is a setup that works for me.

Regards,
Eugen



Zitat von "Francesco Piraneo G." <fpiraneo@xxxxxxxxxxx>:

Hi Eugen,

1. I'm running on a test cluster manually installed under debian 10;

2. No container at all;

3. To install rados gateway I followed instructions here: https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html/installation_guide_for_red_hat_enterprise_linux/manually-installing-ceph-object-gateway

4. Following the instructions in 3. everything run fine if the gateway is installed on the mon1 host;

5. If i follow the same instructions in 3. to install the gateway on a different machine, rados gateway run, can be queried by a web browser (that's mean: is online and listening) but cannot be interfaced with dashboard;

6. rgw_dns_name! Cool question! If you follow what indicated on the link in 3.:

rgw dns name = <obj_gw_hostname>.example.com
Where <obj_gw_hostname> is a short host name of the gateway node. To view the short host name, use the hostname -s command.

But if you go to https://docs.ceph.com/en/latest/radosgw/config-ref/#confval-rgw_dns_name:

rgw_dns_name

The DNS name of the served domain. See also the hostnames setting within regions.


So: I have to indicate the hostname or the DNS (name or address) for the domain?


I think 99% of the confusion is due to VERY POOR documentation!!


Thanks for help.

Francesco

That basically was my check list, it was all I had to do in my lab to set it up. The guide to setup a RGW manually refers to non-containerized environments, did you "adopt" it with cephadm or is it still running outside of a container? You wrote that you switched the RGW host from MON, I think it would help if you shared the steps you did to create and configure the RGW as well as the process to move it to a different host. Is the "rgw_dns_name" set in the ceph.conf (if it's non-container)? Does it resolve properly? Without knowing the details of your setup it's difficult to help.
