Blance ---LVS DR
1.Configuration Environment
system version:redhat v4u5
VIP:10.148.55.45
test1:10.148.55.43
test2:10.148.55.44
rpm:ipvsadm-1.24-6
piranha-0.8.2-1
2.Install RPM Packages
test1#rpm -ivh ipvsadm-1.24-6.rpm
piranha-0.8.2-1.rpm
test2#rpm -ivh ipvsadm-1.24-6.rpm
piranha-0.8.2-1.rpm
3.Start piranha service
test1#service piranha-gui start
test1#piranha-gui passwd
4.Open web for configuration
Generate following:
/etc/sysconfig/ha/lvs.cf
serial_no = 25
primary = 10.148.55.43
service = lvs
backup_active = 1
backup = 10.148.55.44
heartbeat = 1
heartbeat_port = 539
keepalive = 6
deadtime = 18
network = direct
debug_level = NONE
monitor_links = 0
virtual FHJLVS {
active = 1
address = 10.148.55.45 eth0:1
vip_nmask = 255.255.252.0
port = 23
use_regex = 0
load_monitor = ruptime
scheduler = wlc
protocol = tcp
timeout = 6
reentry = 15
quiesce_server = 1
server AP1 {
address = 10.148.55.43
active = 1
weight = 1
}
server AP2 {
address = 10.148.55.44
active = 1
weight = 1
}
}
5. Start service pulse
test1#service pulse start
6. Confirm ipvs table
test1# ipvsadm
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP oratesta:telnet wlc
-> test1:telnet Local 1 0 0
-> test2:telnet Route 1 0 0
7.Ignore arp respondence
echo “1” >/proc/sys/net/ipv4/conf/lo/arp_ignore
echo “1” >/proc/sys/net/ipv4/conf/all/arp_ignore
echo “1” >/proc/sys/net/ipv4/conf/default/arp_ignore
echo “2” >/proc/sys/net/ipv4/conf/lo/arp_announce
echo “2” >/proc/sys/net/ipv4/conf/all/arp_announce
echo “2” >/proc/sys/net/ipv4/conf/default/arp_announce
8.rs2#ifconfig lo:1 10.150.4.245 netmask 255.255.255.255
broadcast 10.150.4.245 up
rs2#route add –host 10.150.4.245 dev lo
9.Test
Try to connect VIP and you will see what you want.
10.Set Lvs backup
test2:#scp test1:/etc/syconfig/ha/lvs.cf /etc/sysconfig/ha
test2:#service pulse start
11.Test backup function
test1#service pulse stop
12.You will see following:
test2# ipvsadm
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP oratesta:telnet wlc
-> test1:telnet Local 1 0 0
-> test2:telnet Route 1 0 0
