BIND-DLZ实验:http://bind-dlz.sourceforge.net/

实验环境:RHEL4,BIND-9.5.0-P2.tar.gz(9.4.0以上版本都已含DLZ补丁),Mysql-5.0.56.tar.gz

1、安装mysql(先安装gcc等相关软件包)

   #tar zxvf mysql-5.0.56.tar.gz     #cd mysql-5.0.56    #./configure --prefix=/usr/local/mysql --localstatedir=/usr/loal/mysql/data --   libexecdir=/usr/local/mysql/lib --disable-shared    #make    #make install    #cd /usr/local/mysql/    #groupadd -g 1003 mysql    #useradd -g 1003 mysql    #chown -R mysql .    #chgrp -R mysql .    #chown -R mysql lib    #./bin/mysql_install_db --user=mysql //以mysql的用户身份安装    #chown -R root .    #./bin/mysqld_safe --user=mysql & //在后台启动mysql

# cd /root/mysql-5.0.56

# cp support-files/my-medium.cnf /etc/my.cnf# cp support-files/mysql.server /etc/rc.d/init.d/mysqld# chmod 700 !$# chkconfig --add mysqld# chkconfig --list mysqld  mysqld 1:off 2:on 3:on 4:on 5:on 6:off# service mysqld start[restart/reload/stop]# vi /etc/my.cnf add this:(防止mysql服务器无查询后8小时自动重连)

wait_timeout = 86400

interactive_timeout = 86400
   #/usr/local/mysql/bin/mysqladmin -uroot password 'aptech'    #./bin/mysql -uroot -paptech

   #echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

   #. !$

  

2、安装bind

   #tar zxvf bind-9.5.0-P2.tar.gz     #cd bind-9.5.0-P2    #./configure --prefix=/usr/local/bind9 --with-dlz-mysql=/usr/local/mysql --enable-threads=no

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

   //--enable-threads=no 关闭多线程 

   //--disable-openssl-version-check 禁止openssl版本的检查    #make    #make install 3、创建database,table

   create database mydata;

   use mydata;

   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(11),

   resp_person varchar(255), 

   primary_ns varchar(255));

 

   create table cnc_dns_records(

  

   insert other_dns_records(zone,host,type,data,ttl,retry)

   values('aaa.com','www','A','192.168.199.2','86400','13');

   insert cnc_dns_records(zone,host,type,data,ttl,retry)

   values('bbb.com','www','A','192.55.199.199','86400','13');

4、编辑/usr/local/bind9/etc/named.conf

   #cd /usr/local/bind9/etc

   #../sbin/rndc-confgen -a

   #../sbin/rndc-confgen > named.conf

   #vi !$   //vi named.conf

   #less named.conf

 # Use with the following in named.conf, adjusting the allow list as needed:  key "rndc-key" {         algorithm hmac-md5;         secret "c4aUV+N7GbOF773V+/LnAA==";  };    controls {         inet 127.0.0.1 port 953                 allow { 127.0.0.1; } keys { "rndc-key"; };  }; # End of named.conf options { directory "/usr/local/bind9/etc/"; pid-file "/usr/local/bind9/var/run/named.pid"; allow-query { any; }; recursion no; version "gaint-d1"; }; include "/usr/local/bind9/etc/cnc.cl"; include "/usr/local/bind9/etc/other.cl"; view "cnc-user" { match-clients { cnc; }; dlz "Mysql zone" { database "mysql {host=localhost dbname=mydata ssl=false port=3306 user=root pass=aptech} {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=mydata ssl=false port=3306 user=root pass=aptech} {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%'}"; }; }; [root@dlz etc]# less cnc.cl acl "cnc"{ 192.168.9.0/24; };

[root@dlz etc]# less other.cl acl "other" { 127.0.0.0/18; };

 

5、启动&测试

[root@dlz ~]# /usr/local/bind9/sbin/named -gc  /usr/local/bind9/etc/named.conf 06-Mar-2009 22:23:02.569 starting BIND 9.5.0-P2 -gc /usr/local/bind9/etc/named.conf 06-Mar-2009 22:23:02.579 loading configuration from '/usr/local/bind9/etc/named.conf' 06-Mar-2009 22:23:02.583 listening on IPv4 interface lo, 127.0.0.1#53 06-Mar-2009 22:23:02.586 listening on IPv4 interface eth0, 192.168.1.5#53 06-Mar-2009 22:23:02.588 Loading 'Mysql zone' using driver mysql 06-Mar-2009 22:23:02.604 default max-cache-size (33554432) applies: view cnc-user 06-Mar-2009 22:23:02.609 Loading 'Mysql zone' using driver mysql 06-Mar-2009 22:23:02.612 default max-cache-size (33554432) applies: view other-user 06-Mar-2009 22:23:02.616 default max-cache-size (33554432) applies: view _bind 06-Mar-2009 22:23:02.621 command channel listening on 127.0.0.1#953 06-Mar-2009 22:23:02.621 ignoring config file logging statement due to -g option 06-Mar-2009 22:23:02.623 running

注:加-gc参数可显示出启动日志,以便出错排查;显示running表示配置正确.
