RGW Multisite (Experimental)
|
||
|
|
============================
|
||
|
|
|
||
|
|
Directions for configuring the RGW Multisite support in ceph-ansible
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
* At least 2 Ceph clusters
|
||
|
|
* 1 RGW per cluster
|
||
|
|
* Jewel or newer
|
||
|
|
|
||
|
|
More details:
|
||
|
|
|
||
|
|
* Can configure a Master and Secondary realm/zonegroup/zone on 2 separate clusters.
|
||
|
|
|
||
|
|
|
||
|
|
## Configuring the Master Zone in the Primary Cluster
|
||
|
|
|
||
|
|
This will setup the realm, zonegroup and master zone and make them the defaults. It will also reconfigure the specified RGW for use with the zone.
|
||
|
|
|
||
|
|
1. Edit the Inventory File
|
||
|
|
|
||
|
|
```
|
||
|
|
[rgws]
|
||
|
|
cluster0-rgw0 rgw_zone=us-east rgw_zonemaster=true
|
||
|
|
```
|
||
|
|
1. Generate System Access and System Secret Keys
|
||
|
|
|
||
|
|
```
|
||
|
|
echo system_access_key: $(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 20 | head -n 1) > multi-site-keys.sh
|
||
|
|
echo system_secret_key: $(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 40 | head -n 1) >> multi-site-keys.sh
|
||
|
|
```
|
||
|
|
1. Edit the RGW Group Vars
|
||
|
|
|
||
|
|
```
|
||
|
|
copy_admin_key: true
|
||
|
|
# Enable Multisite support
|
||
|
|
rgw_multisite: true
|
||
|
|
rgw_realm: gold
|
||
|
|
rgw_zonegroup: us
|
||
|
|
system_access_key: 6kWkikvapSnHyE22P7nO
|
||
|
|
system_secret_key: MGecsMrWtKZgngOHZdrd6d3JxGO5CPWgT2lcnpSt
|
||
|
|
```
|
||
|
|
|
||
|
|
**Note:** replace the system_access_key and system_secret_key values with the ones you generated
|
||
|
|
|
||
|
|
1. Run the ceph-ansible playbook on your 1st cluster
|
||
|
|
|
||
|
|
Note: If you have already installed a cluster with ceph-ansible, you can use the `rgw-configure.yml` playbook as a shortcut (Only runs the ceph-rgw role)
|
||
|
|
|
||
|
|
## Configuring the Secondary Zone in a Separate Cluster
|
||
|
|
|
||
|
|
```
|
||
|
|
[rgws]
|
||
|
|
cluster1-rgw0 rgw_zone=us-west rgw_zonesecondary=true
|
||
|
|
```
|
||
|
|
|
||
|
|
1. Edit the RGW Group Vars
|
||
|
|
|
||
|
|
```
|
||
|
|
copy_admin_key: true
|
||
|
|
# Enable Multisite support
|
||
|
|
rgw_multisite: true
|
||
|
|
rgw_realm: gold
|
||
|
|
rgw_zonegroup: us
|
||
|
|
rgw_pullhost: cluster1-rgw0.fqdn
|
||
|
|
system_access_key: 6kWkikvapSnHyE22P7nO
|
||
|
|
system_secret_key: MGecsMrWtKZgngOHZdrd6d3JxGO5CPWgT2lcnpSt
|
||
|
|
```
|
||
|
|
|
||
|
|
**Note:** pullhost should be the host of the RGW that is configured as the Zone Master
|
||
|
|
**Note:** system_access_key and system_secret_key should match what you used in the 1st cluster
|
||
|
|
|
||
|
|
|
||
|
|
1. Run the ceph-ansible playbook on your 2nd cluster
|
||
|
|
|
||
|
|
Note: If you have already installed a cluster with ceph-ansible, you can use the `rgw-configure.yml` playbook as a shortcut (Only runs the ceph-rgw role)
|
||
|
|
|
||
|
|
## Conclusion
|
||
|
|
|
||
|
|
You should now have a master zone on cluster0 and a secondary zone on cluster1 in an Active-Active mode.
