I have configured IPVSADM on a server with two real nodes. The nodes are running mysql. What I have found is that return trips open up new connections (would could be indicative of a different problem). The original connection still appears open on the mysql server for a long time (currently 8000 seconds). On the client it sometimes sits in a closing state.
IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn TCP 10.80.55.11:3917 wlc persistent 300 -> 10.80.50.3:3917 Masq 100 0 0 -> 10.80.50.2:3917 Masq 100 0 0 I'm sure that others in the past have worked through this on mysql, but everything that I can find on mysql has more to do with keepalive and ldirectory than anything else. In my case I don't need this. All of the real servers are read only slaves, so keeping the most current one is not important in this case. I set it for persistent connections, and when it appears to bind it to a single server, which is fine. When I set the applications to run against a single server, connections are opened, processed and closed within a few seconds. On the balanced nodes, I see a FIN_WAIT2 on the real server side and a CLOSING on the client site. Do I need to worry about this? The time of these just seem to be longer than what I would expect from a normal close. Any advice on how what the proper configuration should be?
