Hiya
Im totally beaten by LVS.
I got, just two machines that im trying to get failover, and loadbalancing
running on for apache2.
I got my heartbeat working and it fails over awesomely. When I stop / start
heartbeat I see it brings up the virtual ip , as well as if I run ipvsadm -L
-n, I see ...
web01:~# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 41.203.4.5:80 rr
-> 41.203.4.7:80 Route 1 0 0
-> 41.203.4.4:80 Local 1 0 0
web01:~#
on either machine.
The problem I have is, if I use siege to test, what I have found is that ..
if I do a HTTP GET to 41.203.4.5, and LVS is running on 41.203.4.4, I get
replys, but when LVS's round robin changes to 41.203.4.7, I get "Error: socket:
unable to connect sock.c:215: No route to host".
(and vice versa i.e. heartbeat running on 41.203.4.7, HTTP GET to 41.203.4.5
and "No route to host" to 41.203.4.4)
My "/etc/ha.d/ldirectord.cf" is relatively straight forward (same config for
both machines).
checktimeout=10
checkinterval=2
autoreload=no
logfile="/var/log/ldirectord.log"
quiescent=yes
virtual=41.203.4.5:80
real=41.203.4.4:80 gate
real=41.203.4.7:80 gate
fallback=127.0.0.1:80
service=http
request="ldirector.html"
receive="Test Page"
scheduler=rr
protocol=tcp
checktype=negotiate
My /etc/sysctl.conf
net.ipv4.ip_forward=1
#net.ipv4.conf.all.rp_filter=1
#net.ipv4.icmp_echo_ignore_broadcasts=1
# Enable configuration of arp_ignore option
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.eth0.arp_ignore = 1
#net.ipv4.conf.eth1.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
net.ipv4.conf.eth0.arp_announce = 2
#net.ipv4.conf.eth1.arp_announce = 2
I dont know where more to look or what more I need to do.
If someone could assist, I would be most grateful.
Kind Regards
Brent Clark
