1） IP配置（配置回环接口添加虚拟ip，让他代为转发）
/sbin/ifconfig lo:0 192.168.1.96 broadcast 192.168.1.96 netmask 255.255.255.255 up
/sbin/ifconfig lo:1 192.168.1.97 broadcast 192.168.1.97 netmask 255.255.255.255 up
/sbin/route add -host 192.168.1.96 dev lo:0
/sbin/route add -host 192.168.1.97 dev lo:1
写入配置文件,开机自动执行 /etc/rc.local
1） ARP（arp）抑制配置,让当客户端发送广播的时候，realserver闭嘴
/etc/sysctl.conf
net.ipv4.conf.lo.arp_ignore=1
net.ipv4.conf.lo.arp_announce=2
net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_announce=2
Director配置1.10和1.98：
1） keepalived配置
#给出部分参考配置
1.10
! Configuration File for keepalived
global_defs {
lvs_id BACKUP
}
vrrp_sync_group MAIL {
group {
VI_1_500
}
}
vrrp_instance VI_1_500 {
state BACKUP
interface eth0
virtual_router_id 95
#1.98的优先级设置为100
priority 150
advert_int 5
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.1.96/24
192.168.1.97/24
}
}
