This may have been answered somewhere; however, I haven't yet found the
right information (most examples I've seen are on older kernels). I'm
trying to load balance an HA MySQL cluster using heartbeat (ultramonkey) on
Centos 4.3 using the Direct Routing method. Ldirector is configured and
working, but the routing is not. I'm played around w/ /etc/sysctl.conf, but
I'm really not sure what I'm doing (I'm somewhat a neophyte, but have been
running a NAT configuration for a few years now).
I have the following in my sysctl.conf file:
net.ipv4.ip_forward = 1
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.eth0.arp_announce = 2
What am I missing? Does anyone have a working configuration for direct
routing on Centos (2.6.9-34.EL kernel).
Connections to don't work to the real servers at follows; however, it works
to the fallback server (localhost):
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.0.1.21:3306 wrr
-> 10.0.1.13:3306 Route 1 0 0
Thanks!
