环境规划

在这里插入图片描述
按照上图配置好ip地址

路由器开启路由功能

Router开启路由转发功能
[Router]#

echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
sysctl -p

RS服务器配置

RS1，RS2 的配置
[RS1]#
[RS2]#

vim lvs_dr_rs.sh
#!/bin/bash
vip=192.168.43.100
mask='255.255.255.255'

rpm -q httpd &> /dev/null || yum -y install httpd &> /dev/null
service httpd start &> /dev/null && echo "The httpd Server is Ready"
echo "<h1>`hostname`</h1>" > /var/www/html/index.html

        echo "Usage: $(basename $0) start|stop"
        exit 1

lvs的配置

lvs的配置

yum install ipvsadmin -y

vim lvs_dr_vs.sh
#!/bin/bash
vip='192.168.43.100'
iface='lo:1'
mask='255.255.255.255'
port='80'
rs1='192.168.43.27'
rs2='192.168.43.37'
scheduler='wrr'
type='-g'
case $1 in
start)
        ifconfig $iface $vip netmask $mask #broadcast $vip up
        iptables -F
        ipvsadm -A -t ${vip}:${port} -s $scheduler
        ipvsadm -a -t ${vip}:${port} -r ${rs1} $type -w 1
        ipvsadm -a -t ${vip}:${port} -r ${rs2} $type -w 1
;;
stop)
        ipvsadm -C
        ifconfig $iface down
;;
*)
        echo "Usage $(basename $0) start|stop"
exit 1
esac

bash lvs_dr_vs.sh start

客户端测试

在 client 机器上测试
[Client]#

while : ;do curl http://192.168.43.100;sleep 0.5; done

注意
由于lvs-dr模型的回应包不经过lvs转发，所以 lvs 的网关可以随便配置一个与 router一个网段的不存在的ip，但是不能不配置。
