LVS-DR模型安装

IP规划：
Director eth0 DIP: 192.168.2.230
eth0:0 VIP: 192.168.2.231
RS1:eth0:192.168.2.229
lo:0:vip:192.168.2.231
RS2:eth0:192.168.2.228
lo:0:vip:192.168.2.231

1.[root@localhost /]# cd /proc/sys/net/ipv4/conf/
[root@localhost conf]# pwd
/proc/sys/net/ipv4/conf

2.[root@localhost conf]# sysctl -w net.ipv4.conf.eth0.arp_announce=2
net.ipv4.conf.eth0.arp_announce = 2
[root@localhost conf]# sysctl -w net.ipv4.conf.all.arp_announce=2
net.ipv4.conf.all.arp_announce = 2

3.[root@localhost conf]# echo 1 > /proc/sys/net/ipv4/conf/eth0/arp_ignore
[root@localhost conf]# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore

4.配置vip：
[root@localhost conf]# ifconfig lo:0 192.168.2.231 broadcast 192.168.2.231 netmask 255.255.255.255 up
5.添加路由：[root@localhost conf]# route add -host 192.168.2.231 dev lo:0
[root@localhost conf]# route add -host 192.168.2.231 dev eth0:0
6.yum install ipvsadm -y
ipvsadm -C
[root@localhost conf]# ipvsadm -L -n
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
