Hi,
i have setup of one director and two real servers (proxy)
After testing on test server, i managed to move LVS to new server.
After moving, i am in 50% cases getting "proxy server you have configured is
not responding" in firefox and 50% images doesn't load in browser (image = new
request)
I did
echo 10 > debug_level and started watching debug log:
# this is ok
Dec 1 14:07:35 cruzz kernel: IPVS: lookup service: fwm 0 TCP
147.32.127.230:3128 hit
# this is the problem i think
Dec 1 14:07:35 cruzz kernel: IPVS: lookup/in TCP
147.32.121.152:42853->147.32.127.230:3128 not hit
-> sometimes, LVS can't match rule for it's settings
my director configuration:
TCP lvs.sh.cvut.cz:3128 sh
-> cache.sh.cvut.cz:3128 Route 1 0 1
-> cache2.sh.cvut.cz:3128 Route 1 1 6
debian woody stable
keepalived 1.1.7
kernel 2.4.28+grsec level high (lvs already built-in)
eth0:110 Link encap:Ethernet HWaddr ...
inet addr:147.32.127.230 Bcast:147.32.127.230 Mask:255.255.255.255
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
147.32.127.192 * 255.255.255.192 U 0 0 0 eth0
my realserver configuration (cache2, cache almost the same):
lo:110 Link encap:Local Loopback
inet addr:147.32.127.230 Mask:255.255.255.255
kernel 2.4.28+grsec level customized
i don't think the problem is in real server, with different director, it worked
fine...
does anybody know anything to do?
thanks,
Jakub Suchy
