The DR mode of the LVS load Balancing cluster

First, the environment

4 Virtual machines: 1 Client, 1 directorserver, 2 realserver. The IP addresses are as follows:

client:192.168.12.22

ds:vip:192.168.12.100,dip:192.168.12.10

realserver1:192.168.12.80

realserver2:192.168.12.81

Second, installation configuration Realserver

RealServer1:

Yum-y Install httpd

Chkconfig httpd on

echo "RealServer1" >>/var/www/html/index.html

Service httpd Start

/sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up

/sbin/route add-host $VIP Dev lo:0

echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore

echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce

echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore

echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce

Sysctl-p

RealServer2:

Yum-y Install httpd

Chkconfig httpd on

echo "RealServer2" >>/var/www/html/index.html

Service httpd Start

/sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up

/sbin/route add-host $VIP Dev lo:0

echo "1" >/proc/sys/net/ipv4/conf/lo/arp_ignore

echo "2" >/proc/sys/net/ipv4/conf/lo/arp_announce

echo "1" >/proc/sys/net/ipv4/conf/all/arp_ignore

echo "2" >/proc/sys/net/ipv4/conf/all/arp_announce

Sysctl-p

Three, installation configuration Directorserver

/sbin/ifconfig eth0:1 $VIP broadcast $VIP netmask 255.255.255.255 up

/sbin/route add-host $VIP Dev eth0:1

Yum-y Install Ipvsadm

Ipvsadm-a-T 192.168.12.100:80-s WLC
