实现 PowerDNS 应用部署
实验准备：
开始实验：

实验准备：

centos7干净环境（centos8暂时不能做缺少依赖包）
poweradmin-2.1.7包

需要的包

[root@centos7 ~]$ll
total 320
-rw-r--r--  1 root root 296469 Jul 10  2014 poweradmin-2.1.7.tgz

开始实验：

下载需要的服务

[root@centos7 ~]$yum install pdns pdns-backend-mysql mariadb-server -y

启动服务建立数据库和服务用户授权

[root@centos7 ~]$systemctl start mariadb.service
[root@centos7 ~]$mysql

参考官方文档建表

GRANT ALL ON powerdns.* TO 'powerdns'@'localhost' IDENTIFIED BY 'magedu';
# 如果在之前就建好库和用户授权这两步就不要做了

修改dns配置文件

[root@centos7 ~]$vim /etc/pdns/pdns.conf
#################################
# launch        Which backends to launch and order to query them in

launch=gmysql       #  找到这行加上下面的配置
gmysql-host=localhost
gmysql-port=3306
gmysql-dbname=powerdns
gmysql-user=powerdns
gmysql-password=taotaobao
# 一定要对应数据库的设置

启动服务

[root@centos7 ~]$systemctl enable --now pdns # 设为开机启动并启动服务
[root@centos7 ~]$ss -ntul

安装httpd和php相关包

[root@centos7 ~]$ yum -y install httpd php php-devel php-gd php-mcrypt php-imap
php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mhash
gettext php-mysqlnd.x86_64

[root@centos7 ~]$systemctl enable --now httpd # 启动服务并设为开机启动

解压poweradmin-2.1.7

[root@centos7 ~]$tar xvf poweradmin-2.1.7.tgz -C /var/www/html/ # 解压到主站点目录下
[root@centos7 ~]$cd /var/www/html/
[root@centos7 html]$mv poweradmin-2.1.7 poweradmin  # 改名隐藏版本号
[root@centos7 html]$ll
total 4
drwxrwxr-x 10 root root 4096 Jul  5  2014 poweradmin

访问web界面安装向导

# 后面必须加install
http://powerdns服务器IP/poweradmin/install/

选择语言
填写数据库信息（这一步结束报错，报缺少PDO的时候下载php-mysqlnd包）
web界面管理dns服务器
授权刚刚建立的普通用户（复制给的命令）
数据库授权

[root@centos7 html]$mysql

设置powerdns访问数据库和指明powerdns所管理的域名

# 在这个目录下创建
[root@centos7 inc]$pwd
/var/www/html/poweradmin/inc
[root@centos7 inc]$vim config.inc.php
[root@centos7 inc]$cat config.inc.php
<?php

$db_host		= 'localhost';
$db_user		= 'admin';
$db_pass		= 'taotaobao';
$db_name		= 'powerdns';
$db_type		= 'mysql';
$db_layer		= 'PDO';

$session_key		= 'exZ4WCH~6Afn41%k(rWUaT]44aA$w^iAS{b-%$JlBuHc$[';

$iface_lang		= 'en_EN';

$dns_hostmaster		= 'admin.taotaobao.org';
$dns_ns1		= 'master.taotaobao.org';
$dns_ns2		= 'slave.taotaobao.org';

[root@centos7 inc]$rm -rf /var/www/html/poweradmin/install/

去掉install登录
web界面搭完dns查询

[root@centos8 ~]#dig www.taotaobao.org @192.168.39.7
