LVS负载均衡集群之DR模式

一、环境

4台虚拟机：1台Client、1台DirectorServer、2台RealServer。IP地址分别如下：

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

二、安装配置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

三、安装配置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

ipvsadm -a -t 192.168.12.100:80 -r 192.168.12.80 -g -w 1

ipvsadm -a -t 192.168.12.100:80 -r 192.168.12.81 -g -w 1

service ipvsadm save

ipvsadm -L -n

参数说明：

-A 添加集群服务；

-t TCP协议；

-s 指定调度算法；

-g 指定为DR模式；

-w 权重；

四、Client访问测试

ab -c 10 -n 1000 http://192.168.12.100/index.html
