修改的地方：
yum install epel-release -y
yum install -y iptables iptables-services 需要下载最新的

镜像版本有了一定的修改，以及powerdns的端口修改成5300（因为要安装的pdns-recurosr是53端口）[root@localhost powerdns]# cat /opt/powerdns/pdns/config/pdns.conf

安装pdns-recursor:
yum install pdns-recursor -y

[root@localhost pdns-recursor]# cat /etc/pdns-recursor/recursor.conf
allow-from=0.0.0.0/0,::/0      #对应权威服务器的allow-recursion 允许哪些ip进行递归
forward-zones-file=/etc/pdns-recursor/zones
forward-zones-recurse=.=223.5.5.5, .=114.114.114.114           # 除forward-zones外其他所有的请求发至223.5.5.5, 114.114.114.114
local-address=0.0.0.0         #对应权威服务器的local-address
local-port=53
setgid=pdns-recursor
setuid=pdns-recursor
[root@localhost pdns-recursor]# cat zones 
test-source.app.cn=192.168.109.169:5300
local-source.app.cn=192.168.109.169:5300
[root@localhost pdns-recursor]# 每次添加zones后：需要重启pdns-recursor
systemctl restart  pdns-recursor
设置成开机自启：
systemctl enable pdns-recuror

在交换机中将修改dns为powerdns的ip
设置成功后，如何测试：
1.windows机器中：
nslookup source.app.cn 192.168.109.169
nslookup source.app.cn
ping source.app.cn
可以通过手动设置windows的dns为192.168.109.169，进行调试。ipconfig -all查看windows的dns
2.centos中，配置DNS1为192.168.109.169，重启网络，ping source.app.cn
