BIND+DLZ+MYSQL

BIND-DLZ实验环境:RHEL4

所用到的软件包:BIND-9.5.0-P2.tar.gz(9.4.2以上版本都已经包含了DLZ补丁)、Mysql-5.0.56.tar.gz

写在前面:DLZ(Dynamically Loadable Zones)，它允许你的区域记录放置到数据库中，并且支持多种数据库。你可以在

BIND-DLZ

上找到相应的资料。

1、先安装mysql

shell>tar zxvf mysql-version.tar.gz

shell>cd mysql-*

shell>./configure --prefix=/usr/local/mysql /

>--localstatedir=/usr/local/mysql/data /

>--libexecdir=/usr/local/mysql/lib /

>--disable-shared

shell>make && make install

安装完成后。

进入安装mysql的目录

>cd /usr/local/mysql

>chown -R mysql .

>chgrp -R mysql .

>chown -R mysql data

>chown -R mysql lib

>groupadd -g 1003 mysql

>adduser -g 1003 mysql

>./bin/mysql_install_db --user=mysql //以mysql用户的身份安装

>chown -R root .

>./bin/mysqld_safe --user=mysql &  //启动mysql并转入后台自行处理

>/usr/local/mysql/bin/mysqladmin -u root -p password '*******'

password:(由于初始密码为空，此处直接敲回车)

>/usr/local/mysql/bin/mysql -u root -p

password:(输入你的密码)

mysql>

2、安装bind

shell>tar zxvf bind-9.5.0-p2.tar.gz

shell>cd bind-9.5.0-p2

shell>./configure --prefix=/usr/local/bind9 --with-dlz-mysql=/usr/local/mysql --enabl-threads=no --disable-openssl-version-check

--with-dlz-mysql=/usr/local/mysql  要求bind安装中支持DLZ

--enabl-threads=no  关闭多线程

--disable-openssl-version-check   这项是禁止openssl版本的检查

shell>make

shell>make install

3、创建数据库、表

mysql>create database mydata;

mysql>use mydata;

mysql>create table other_dns_records (

>zone varchar (255),

>host varchar (255),

>type varchar (255),

>data varchar (255),

>ttl int(11),

>mx_priority varchar (255),

>refresh int(11),

>retry int(11),

>expire int(11),

>minimum int(11),

>serial bigint(20),

>resp_person varchar (255),

>primary_ns varchar (255)

>);

mysql>create table cnc_dns_records (

>zone varchar (255),

>host varchar (255),

>type varchar (255),

>data varchar (255),

>ttl int(11),

>mx_priority varchar (255),

>refresh int(11),

>retry int(11),

>expire int(11),

>minimum int(11),

>serial bigint(20),

>resp_person varchar (255),

>primary_ns varchar (255)

>);

>//向表中添加一条记录

>insert into other_dns_records (zone,host,type,data,ttl,retry) values ('aaa.com','www','A','192.168.199.2','86400','15');

>insert into cnc_dns_records (zone,host,type,data,ttl,retry) values ('bbb.com','www','A','192.199.22.22','86400','13');

4、编辑/usr/local/bind9/etc/named.conf

>cd /usr/local/bind9/etc

>../sbin/rndc-config -a

>../sbin/rndc-config > named.conf

>vi !$

//删除# Use with the following in named.conf, adjusting the allow list as needed: 以前的行

将# Use with the following in named.conf, adjusting the allow list as needed: 和 # End of named.conf 之间的行前#号

最终的etc/named.conf文件如下：

# Use with the following in named.conf, adjusting the allow list as needed:

key "rndc-key" {

algorithm hmac-md5;

secret "2rkqGUle0VlsawCL2+IKsA==";

};

controls {

inet 127.0.0.1 port 953

allow { 127.0.0.1; } keys { "rndc-key"; };

};

# End of named.conf

options {

directory "/usr/local/binid/etc/";

pid-file "/usr/local/binid/var/run/named.pid";

allow-query { any; };

recursion no;

version "gaint-d1";

};

include "/usr/local/binid/etc/cnc.cl";

include "/usr/local/binid/etc/other.cl";

view "cnc-user" {

match-clients { cnc; };

dlz "Mysql zone" {

database "mysql

{host=localhost dbname=mydb ssl=false port=3306 user=root pass=abc123!}

{select zone from cnc_dns_records where zone='%zone%'}

{select ttl, type, mx_priority, case when lower(type)='txt' then concat('/"', data, '/"')

when lower(type)='soa' then concat_ws(' ',data,resp_person,serial,refresh,retry,expire,minimum) else data end as mydata from cnc_dns_records where zone='%zone%' and host='%record%'}";

};

};

view "other-user" {

match-clients { other; };

dlz "Mysql zone" {

database "mysql

{host=localhost dbname=mydb ssl=false port=3306 user=root pass=abc123!}

{select zone from other_dns_records where zone='%zone%'}

{select ttl, type, mx_priority, case when lower(type)='txt' then concat('/"', data, '/"')

when lower(type)='soa' then concat_ws(' ',data,resp_person,serial,refresh,retry,expire,minimum) else data end as mydata from other_dns_records where zone='%zone%' and host='%record%'}";

};

};

etc/cnc.cl如下：

acl "cnc" {

192.168.9.0/24;

};

etc/other.cl如下：

acl "other" {

127.0.0.0/18;

};

5、测试

打开named测试/usr/local/bind9/sbin/named -g -d 1 -c /usr/local/bind9/etc/named.conf

注：如果不想写全路径来启动bind和mysql的话，可以编辑：

>vi /root/.bash_profile

加入如下两行：

PATH=$PATH:/usr/local/bind9/sbin

PATH=$PATH:/usr/local/mysql/bin/

保存退出

> . /root/.bash_profile (或者：. !$)

这次的实验只是做了一部分，可能也会用到区域传送。这些查询可以参照

BIND-DLZ
