智能DNS部署文档（基于powerDNS）

1.安装libmaxminddb

wget https://github.com/maxmind/libmaxminddb/archive/refs/tags/1.6.0.tar.gz
./configure
make -j4
make check
make install 
echo /usr/local/lib  >> /etc/ld.so.conf.d/local.conf
ldconfig

下载GeoLite2免费地址库

https://dev.maxmind.com/geoip/geolite2-free-geolocation-data?lang=en
这里使用GeoLite2-City
文档文件夹内已附有数据库，无需重新下载。GeoLite2免费地址库支持在线更新，需要到官网注册账号申请免费license

2.安装Pdns Authoritative Server（权威服务器）

这里需要预先安装好mysql

wget https://downloads.powerdns.com/releases/pdns-4.6.0.tar.bz2
tar xvf pdns-4.6.0.tar.bz2 
cd pdns-4.6.0

开启mysql和geoip后端、并指定mysql目录、开启lua-record

./configure --prefix=/usr/local/powerdns --with-modules="bind gmysql geoip" --with-mysql=/usr/local/mysql --enable-verbose-logging --enable-lua-records
make -j4 && make install

遇到错误

configure: error: cannot find Boost headers version >= 1.42.0
解决
yum install boost-devel -y
错误
configure: error: Could not find yaml-cpp
解决
yum install yaml-cpp yaml-cpp-devel -y

创建powerdns数据库、数据表

mysql -uroot -p

create database pdns;
use pdns;

gmysql-host=localhost
gmysql-port=3306
gmysql-user=root
gmysql-password=123456
gmysql-dbname=pdns
write-pid=yes

api=yes   #开启api
api-key=自定义 #配置api访问密钥
webserver=yes
webserver-address=0.0.0.0
webserver-allow-from=0.0.0.0/0   #api允许访问来源
webserver-port=8081   #api访问端口
config-dir=/usr/local/powerdns/etc    #指定pdns配置文件目录
enable-lua-records=shared    #开启lua-record
geoip-database-files=/usr/local/powerdns/etc/GeoLite2-City.mmdb   #指定geoip数据库

启动pdns
