Hi, I am trying to create multi-region multi-appliance setup with euwe-1 and do not know where to even start. I have started appliance1, and created region 99 on it. I have started appliance2 and created region 0 on it. Then, reading Redhat cloudforms documentation:
- Add replication worker settings pointing to the VMDB for Region 99.
- Enable Database Synchronization Server role on one Server in the Region. If you have a second Server in the same region, do not enable the DB Synchronization role. Do not enable more than one Database Synchronization Role per Region
First, I do not seem to have a DB Synchronization server role in euwe. Second, I could not find anywhere how to add replication worker settings.
appliance_console on euwe has ‘Configure replication’ option where I can configure ‘Primary’ and ‘Standby’ servers. I think this might be intra-region DB replication, but I am not sure.
Region settings in web UI has ‘Replication’ option where I can configure it as ‘remote’ or ‘global’. Sounds promising, but I am not sure what region 99 should be, and what region 0 should be.
Is there any documentation on how to actually configure DB synchronization?
Thank you very much.
