Bind9使用MySQL来管理Zone

部署环境：VirtualBox4.3.18 + 64位Redhat5.6 + Bind9.10 + MySQL5.6 + mysql-bind。

VirtualBox中对Redhat的网络连接方式不要用默认的网络地址转换（NAT）， 选用桥接网卡，这样主机和虚拟机可以双向通信。

MySQL5.6以RPM包形式安装，其默认路径分别如下。
BIN：/usr/bin/mysql
头文件H：/usr/include/mysql
库文件LIB：/usr/lib64  ##可以通过mysql_config --libs命令知道

1、解压Bind和mysql-bind，将mysql-bind下的mysqldb.h拷贝到bind的bin/named/include/named目录下，将mysqldb.c拷贝到bind的bin/named目录下。

2、修改Bind的bin/named目录下的MakeFile.in文件。

DBDRIVER_OBJS = mysqldb.@O@
DBDRIVER_SRCS = mysqldb.c
DBDRIVER_INCLUDES = -I'/usr/include/mysql/'
DBDRIVER_LIBS = -L'/usr/lib64/mysql' -lmysqlclient -lz -lcrypt -lnsl -lm -lc -lnss_files -lnss_dns -lresolv -lc -lnss_files -lnss_dns -lresolv

3、编辑bind源文件bin/named/main.c
--包含mysqldb.h，#include <named/mysqldb.h>
--在函数setup(void)里面ns_server_create()的前面添加mysqldb_init();
--在函数cleanup(void)里面ns_server_destroy()的后面添加mysqldb_clear();

4、编译安装bind
./configure
make
make install

5、创建数据库bind9，创建表kaopu。

CREATE TABLE kaopu (
  `name` varchar(255) default NULL,
  ttl int(11) default NULL,
  rdtype varchar(255) default NULL,
  rdata varchar(255) default NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

初始化数据：

insert into `kaopu` (`name`, `ttl`, `rdtype`, `rdata`) values('www.kaopu.com','3600','A','10.3.19.14');
insert into `kaopu` (`name`, `ttl`, `rdtype`, `rdata`) values('ns1.kaopu.com','3600','A','127.0.0.1');
insert into `kaopu` (`name`, `ttl`, `rdtype`, `rdata`) values('kaopu.com','3600','NS','ns1.kaopu.com');
insert into `kaopu` (`name`, `ttl`, `rdtype`, `rdata`) values('kaopu.com','3600','SOA','kaopu.com. www.kaopu.com. 2003080800 172800 900 1209600 3600');

6、配置Bind
--生成控制文件
rndc-confgen > /etc/named/rndc.conf

# Start of rndc.conf
key "rndc-key" {
        algorithm hmac-md5;
        secret "rHLs03YrlkgYVhFl7dZZ7A==";
};

options {
        default-key "rndc-key";
        default-server 127.0.0.1;
        default-port 953;
};
# End of rndc.conf

# Use with the following in named.conf, adjusting the allow list as needed:
# key "rndc-key" {
#       algorithm hmac-md5;
#       secret "rHLs03YrlkgYVhFl7dZZ7A==";
# };
#
# controls {
#       inet 127.0.0.1 port 953
#               allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf

--生成named.conf
tail -10 rndc.conf | head -9 | sed s/#\ //g > named.conf
--编辑named.conf

key "rndc-key" {
        algorithm hmac-md5;
        secret "rHLs03YrlkgYVhFl7dZZ7A==";
};

controls {
        inet 127.0.0.1 port 953
              allow { 127.0.0.1; } keys { "rndc-key"; };
};

include "/etc/named/named.conf.options";

zone "." {
        type hint;
        file "/etc/named/named.root";
};

zone "localhost" {
        type master;
        file "/etc/named/named.localhost";
};

zone "kaopu.com" IN {
        type master;
        notify no;
        database "mysqldb bind9 kaopu localhost bind9 welcome1";
};

/etc/named/named.conf.options如下

options {
        directory "/etc/named";
        allow-query { any; };
        allow-recursion { any; };
        allow-query-cache {any;};
        datasize 2098;
};

/etc/named/named.localhost如下

$TTL    600
@               IN SOA localhost. root.localhost. (2011080101 3H 15M 1W 1D)
@               IN NS localhost.
localhost.      IN A 10.3.19.79

/etc/named/named.root如下

named.root文件可由命令生成：dig -t NS . > /etc/named/named.root

database "mysqldb bind9 kaopu localhost bind9 welcome1";解释如下：
bind9－数据库名
kaopu－数据库表名
localhost－数据库主机名
bind9－用户名
welcome1－密码

7、验证MySQL-bind SDB方式。
输入命令：dig @127.0.0.1 www.kaopu.com
响应如下：
