New in this forum, trying to get a setup going here at work with the following ( as the title suggests );
A. 2 provider IP addresses ( let’s say - for proxyA - 192.168.10.5 & proxyB - 192.168.20.5 ) for 2 haproxy nodes, located in 2 data centers.
B. Need to set these boxes up with HA ( active / standby ), but I was told that we can’t run VRRP, as both servers are not in the same subnet.
So, the next question comes – what the next best method to do this?
idea #1 setup DNS RR, with a short TTL. Although there is a lot of client dependency here, it should work in general.
idea #2 setting BGP peering for announcing routes. This was a suggestion from someone, not fully sure what it entails on the proxy server config.
So, i guess my question is – how does configuration like this are handled ? I would like to them to be full HA ( between 2 servers ), but I guess I can’t have it all while I have 2 separate provider IP address for 2 proxy nodes. Have any of you done anything like this? If so, could you take a few mins of your time to explain how it has been done and may be a share a config snippet with me?
Thanks a lot for your help in advance!
