# lvs-wordpress (10.0.0.98):
[root@lvs-wordpress ~]# yum install ipvsadm -y

[root@lvs-wordpress ~]# ip link set up tunl0

9、配置防火墙
# firewalld (10.0.0.108):
[root@firewalld ~]# echo 1 > /proc/sys/net/ipv4/ip_forward
[root@firewalld ~]# iptables -t nat -A PREROUTING -d 192.168.0.200 -p tcp --dport 80 -j DNAT --to-destination 10.0.0.200:80
[root@firewalld ~]# iptables -t nat -A PREROUTING -d 192.168.0.201 -p tcp --dport 80 -j DNAT --to-destination 10.0.0.201:80
[root@firewalld ~]# iptables -t nat -nvL
Chain PREROUTING (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
4 240 DNAT tcp -- * * 0.0.0.0/0 192.168.0.200 tcp dpt:80 to:10.0.0.200:80
3 180 DNAT tcp -- * * 0.0.0.0/0 192.168.0.201 tcp dpt:80 to:10.0.0.201:80
10、配置client Router
# client Router（192.168.0.88）
[root@client-router ~]#echo 1 > /proc/sys/net/ipv4/ip_forward
11、配置DNS服务器
# DNS （192.168.10.100）：
[root@DNS ~]# apt install -y bind9 bind9-utils
[root@DNS ~]# cd /etc/bind/
[root@DNS bind]# vim /etc/bind/named.conf.options
dnssec-validation no; #取消此行注释
[root@DNS bind]# vim named.conf.default-zones
zone "wang.org" {
type master;
file "/etc/bind/wang.org.zone";
};
[root@DNS bind]# cp db.local wang.org.zone
[root@DNS bind]# vim wang.org.zone
$TTL 604800
@ IN SOA admin admin.wang.org. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
IN NS admin
admin IN A 192.168.10.100
shopxo IN A 192.168.0.200
wordpress IN A 192.168.0.201
[root@DNS bind]#systemctl restart named.service
[root@DNS bind]#systemctl status bind9.service #查看状态是否报错
[root@DNS bind]#dig @127.1 wordpress.wang.org
12、client测试
windows当做客户端：
1、需改网卡dns：需改dns所在网卡dns和外网dns（我这里是vmnet3 以太网）
2、清除dns缓存
3、ping测试
4、浏览器测试
