lvs dr

1.安装ipvsadm

 

2.在rs上将ifcfg-XXXXX复制为 ifcfg-lo:1 并修改

#############

NAME="lo:1"

DEVICE="lo:1"

IPADDR=192.168.10.200    #LB的IP

NETMASK=255.255.255.255 #32位掩码

GATEWAY=192.168.10.2

DNS1=192.168.10.2

############

重启网络服务

systemctl restart network

 

3.添加到lo:1的路由

route add -host 192.168.10.200 dev lo:1

 

4.关闭arp报文

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

#还原方法echo 0 到以上

 

5.(LB)添加虚拟ip

cp ifcfg-XXX ifcfg-XXX:0

修改

#######

NAME="XXX:1"

DEVICE="XXX:1"

IPADDR=192.168.10.200    #LB的IP

######

systemcrl restart network

#或

ifconfig ens33:2 192.168.10.210 netmask 255.255.255.0 up

 

6.在LB上 添加ipvsadm规则

ipvsadm -A -t 192.168.10.200:80 -s rr

ipvsadm -a -t 192.168.10.200:80 -r 192.168.10.129 -g

ipvsadm -a -t 192.168.10.200:80 -r 192.168.10.130 -g

#-g 为DR模式

ipvsadm -Ln
