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?
Gary
