LVS之DR模式配置 - morris131/morris-book GitHub Wiki

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]

  1. 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
