每个 rs 都要有一个公网 IP
director:
1）vim /usr/local/sbin/lvs_dr.sh
#!/bin/bash
echo 1 > /proc/sys/net/ipv4/ip_forward
ipv=/sbin/ipvsadm
vip=192.168.11.100
rs1=192.168.11.160
rs2=192.168.11.20
(ifconfig eth0:0 down) (该行在换wrr或其他 加上这一行 原始不用加)
ifconfig eth0:0 $vip broadcast $vip netmask 255.255.255.255 up
route add -host $vip dev eth0:0
$ipv -C
$ipv -A -t $vip:80 -s rr
$ipv -a -t $vip:80 -r $rs1:80 -g -w 1 (-g是dr模式 -m是nat模式)
$ipv -a -t $vip:80 -r $rs2:80 -g -w 1
rs:
1）vim /usr/local/sbin/lvs_rs.sh
#!/bin/bash
vip=192.168.11.100
ifconfig lo:0 $vip broadcast $vip netmask 255.255.255.255 up
route add -host $vip lo:0
echo "1" > /proc/sys/net/ipv4/conf/lo/arp_ignore
echo "2" > /proc/sys/net/ipv4/conf/lo/arp_announce
echo "1" > /proc/sys/net/ipv4/conf/all/arp_ignore
echo "2" > /proc/sys/net/ipv4/conf/all/arp_announce
两个 rs 运行一下脚本
