hello
I'm having an issue setting up LVS-DR--->Squid
4 Nodes of RHEL 4
kernel-2.6.9-22.EL
2 LVS Load Balancers -> 2 Squid Real Servers
on my primary and secondary directors using piranha:
in sysctl.conf
net.ipv4.ip_forward = 1
lvs.cf:
serial_no = 33
primary = x.x.166.133
service = lvs
backup_active = 1
backup = x.x.166.132
heartbeat = 1
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = direct
debug_level = NONE
monitor_links = 0
virtual Squid {
active = 1
address = x.x.166.181 eth0:1
vip_nmask = 255.255.255.0
port = 3128
persistent = 86400
send = "GET / HTTP/1.0rnrn"
expect = "HTTP"
use_regex = 0
load_monitor = none
scheduler = wlc
protocol = tcp
timeout = 6
reentry = 15
quiesce_server = 1
server squid1 {
address = x.x.166.179
active = 1
weight = 1
}
server squid2 {
address = x.x.166.180
active = 1
weight = 1
}
}
ipvsadm output: (I'm not getting any Route, ActiveConn or InactConn, not
even 0 for some reason)
CURRENT LVS ROUTING TABLE
IP Virtual Server version 1.2.0 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP x.x.166.181:3128 wlc persistent 86400000 FFFFFFFF
(looks like my LVS nodes can't talk to my real servers?)
on my two squid real servers:
installed the arptables_jf service
issued the following commands:
arptables -A IN -d <virtual_ip> -j DROP
arptables -A OUT -d <virtual_ip> -j mangle --mangle-ip-s <real_ip>
service arptables_jf save
chkconfig --level 2345 arptables_jf on
in rc.local:
ifconfig eth0:1 <virtual_ip> netmask 255.255.255.0 broadcast x.x.255.255 up
My primary lvs node is barking in /var/log/messages about timing out to my
real servers, although they are up as I can go directly to them bypassing
lvs and I get connections. I can ping my VIP, I'm not sure what else to
check.
Thanks in advance for any help.
