bind9 dlz mysql 配置

内容简介：bind9 dlz mysql 配置

1.数据库安装

yum -y install mysql-community-server mysql-community-devel

2.编译安装bind 一些基础的包，请参考前一章

./configure –with-dlz-mysql –enable-largefile –enable-threads=no –prefix=/migu/bind –with-libtool –enable-epoll –with-openssl

make -j 8 && make -j 8 install

3.数据库初始化:

CREATE SCHEMA `bind` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci ;

CREATE TABLE IF NOT EXISTS `dns_records` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `zone` varchar(255) NOT NULL,
  `host` varchar(255) NOT NULL DEFAULT '@',
  `type` enum('A','MX','CNAME','NS','SOA','PTR','TXT','AAAA','SVR','URL') NOT NULL,
  `data` varchar(255) DEFAULT NULL,
  `ttl` int(11) NOT NULL DEFAULT '3600',
  `mx_priority` int(11) DEFAULT NULL,
  `view`  enum('any', 'CHINANET', 'Unicom', 'CNC', 'ours') NOT NULL  DEFAULT "any" ,
  `priority` tinyint UNSIGNED NOT NULL DEFAULT '255',
  `refresh` int(11) NOT NULL DEFAULT '28800',
  `retry` int(11) NOT NULL DEFAULT '14400',
  `expire` int(11) NOT NULL DEFAULT '86400',
  `minimum` int(11) NOT NULL DEFAULT '86400',
  `serial` bigint(20) NOT NULL DEFAULT '2015050917',
  `resp_person` varchar(64) NOT NULL DEFAULT 'ddns.net',
  `primary_ns` varchar(64) NOT NULL DEFAULT 'ns.ddns.net.',
  PRIMARY KEY (`id`),
  KEY `type` (`type`),
  KEY `host` (`host`),
  KEY `zone` (`zone`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

插入SOA数据：

INSERT INTO `dns_records` (`zone`, `host`, `type`, `data`, `ttl`,`mx_priority`,  `refresh`, `retry`, `expire`, `minimum`, `serial`, `resp_person`, `primary_ns`) VALUES  (‘xieyugui.com’, ‘@’, ‘SOA’, ‘ns1.xieyugui.com.’, 10, NULL, 600, 3600, 86400, 10, 2017060801, ‘root.xieyugui.com.’, ‘ns1.xieyugui.com.’);

插入@ NS数据：

INSERT INTO `dns_records` (`zone`, `host`, `type`, `data`) VALUES  (‘xieyugui.com’, ‘@’, ‘NS’, ‘ns1.xieyugui.com.’),  (‘xieyugui.com’, ‘@’, ‘NS’, ‘ns2.xieyugui.com.’);

插入NS A数据：

INSERT INTO `dns_records` (`zone`, `host`, `type`, `data`) VALUES  (‘xieyugui.com’, ‘ns1’, ‘A’, ‘192.168.10.5’),  (‘xieyugui.com’, ‘ns2’, ‘A’, ‘192.168.1.111’);

插入www A记录：

INSERT INTO `dns_records` (`zone`, `host`, `type`, `data`, `ttl`, `view`) VALUES  (‘xieyugui.com’, ‘www’, ‘A’, ‘192.168.1.111’, 360, ‘any’),  (‘xieyugui.com’, ‘app’, ‘A’, ‘192.168.1.112’, 360, ‘CHINANET’),  (‘xieyugui.com’, ‘dev’, ‘A’, ‘192.168.1.113’, 360, ‘any’),  (‘xieyugui.com’, ‘db’, ‘A’, ‘192.168.1.114’, 360, ‘any’);

插入CNAME 记录：

INSERT INTO dns_records (zone,host,type,DATA,view) VALUES  (‘xieyugui.com’, ‘blog’, ‘CNAME’, ‘www’,’CNC’);

} ;

貌似上面的view.conf里面的select逻辑有点问题，但是整体还是能跑通的，后面有空再整理一下
