此次讲述一下LVS-DR的另一个模型

DIP、RIP属于私有IP地址，VIP属于公网IP，即三者不属于同一网段

架构图：

集群配置

1、Director配置

DIP配置#ifconfig eth0 192.168.0.170/24 up#route add default gw 192.168.0.254#ifconfig

Director上配置VIP        #ifconfig eth0:0 172.16.249.100 netmask 255.255.255.255 broadcast 172.16.249.100 up

#route add -host 172.16.249.100 dev eth0:0 添加主机路由#route  -n

2、RS1配置

RS1内核参数配置 #  echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore #  echo 1> /proc/sys/net/ipv4/conf/eth0/arp_ignore #  echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce #  echo 2 > /proc/sys/net/ipv4/conf/eth0/arp_announce

配置RS1的RIP#ifconfig eth0 192.168.0.171/24 up#route add default gw 192.168.0.254

配置RS1的VIP#ifconfig lo:0 172.16.249.100 netmask 255.255.255.255 broadcast 172.16.249.100 up#route add -host 172.16.249.100 dev lo:0#ifconfig

     #route -n

配置web#vim /var/www/html 
welcome to RS1!
#service httpd restart关闭防火墙#service  iptables stop

3、 RS2配置

RS2内核参数配置#echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore#echo 1 > /proc/sys/net/ipv4/conf/eth0/arp_ignore#echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce#echo 2 > /proc/sys/net/ipv4/conf/eth0/arp_announce

配置DIP#ifconfig eth0 192.168.0.172/24 up#route add default gw 192.168.0.254#ifconfig

   

   

配置VIP#ifconfig lo:0 172.16.249.100 netmask 255.255.255.255 broadcast 172.16.249.100 up#ifconfig

         

   

    

#route add -host 172.16.249.100 dev lo:0#route -n

 

   

4、 Director 调度器设置集群服务及RS

    

#ipvsadm -A -t 172.16.249.100:80 -s rr#ipvsadm -a -t 172.16.249.100:80 -r 192.168.0.171 -g#ipvsadm -a -t 172.16.249.100:80 -r 192.168.0.172 -g#ipvsadm -L -n

   

   

5、 客户端测试

   

    

CIP：192.168.1.100NETMASK：255.255.255.0GATEWAY: 192.168.1.254

     

   

   刷新

   

   

总结：LVS-DR 集群模式（二）已成功实现，rr算法已成功实现！

   

  PS：水平有限，有问题请指出共同丰富！
