一、top图：
director：192.168.146.20
vip：192.168.146.19
realserver1：192.168.146.21
vip：192.168.146.19
realserver2：192.168.146.22
vip：192.168.146.19
二、director配置：
讲eth0复制出来一份，命名为eth0:1，ip地址配置为vip的地址。
#mount /dev/cdrom /mnt
#rpm -ivh /mnt/Packages/ipvsadm-1.26-2.el6.x86_64.rpm
# ipvsadm -A -t 192.168.146.19:80 -s rr
# ipvsadm -a -t 192.168.146.19:80 -r 192.168.146.21:80 -g
#ipvsadm -a -t 192.168.146.19:80 -r 192.168.146.22:80 -g
# ipvsadm -L -n
三、rs1：
#vim /etc/sysctl.conf
net.ipv4.conf.eth0.arp_ignore = 1 #追加这两行
net.ipv4.conf.eth0.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
# yum install -y httpd
# echo “this is rs1” > /var/www/html/index.html
# service httpd restart
四、rs2：
#vim /etc/sysctl.conf
net.ipv4.conf.eth0.arp_ignore = 1 #追加这两行
net.ipv4.conf.eth0.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
# yum install -y httpd
# echo “this is rs1” > /var/www/html/index.html
# service httpd restart
五、测试：
弄台随意的linux机器:
