LVS之DR模式配置

网络拓扑图如下：


1. Director Server配置

[root@chen ~]# ifconfig eth0:1 192.168.10.100/32 broadcast 192.168.10.100 up
[root@chen ~]# route add -host 192.168.10.100 dev eth0:1
[root@chen ~]# ifconfig eth0:1 192.168.92.100/32 broadcast 192.168.92.100 up
[root@chen ~]# route add -host 192.168.92.100 dev eth0:1
[root@chen ~]# ipvsadm -A -t 192.168.92.100:80 -s wlc
[root@chen ~]# ipvsadm -a -t 192.168.92.100:80 -g -r 192.168.92.131 -w 1
[root@chen ~]# ipvsadm -a -t 192.168.92.100:80 -g -r 192.168.92.128 -w 2
[root@chen ~]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
  -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
TCP  192.168.92.100:80 wlc
  -> 192.168.92.128:80            Route   2      0          0         
  -> 192.168.92.131:80            Route   1      0          0         
[root@chen ~]# service ipvsadm save
ipvsadm: Saving IPVS table to /etc/sysconfig/ipvsadm:      [确定]

2. Real Server1的配置

[root@chen ~]# echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore 
[root@chen ~]# echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce 
[root@chen ~]# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore 
[root@chen ~]# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce 
[root@chen ~]# ifconfig lo:0 192.168.92.100/32 broadcast 192.168.92.100 up
[root@chen ~]# route add -host 192.168.92.100 dev lo:0
[root@chen ~]# ifconfig

3. Real Server2的配置与Real Server1的配置一样，ip为192.168.92.131
