BIND9 + MySQL (MySQL BIND SDB Driver)

BIND 与 MySQL结合，在BIND9里面已经集成了与数据库连接的模块dlz，但是dlz与mysql结合有一个很致命的缺点就是只能将bind编译

成单线程，这就大大降低了bind的性能，所以选择了其他模块MySQL BIND SDB Driver

 

 

在Project Page里面下载 mysql-bind.tar.gz (包里面的README文件其实有讲如何编译)

 

cp mysqldb.c and mysqldb.h to bind9/bin/named and bind9/bin/named/include/named

 

vim bind9/bin/named/Makefile.in

 

DBDRIVER_OBJS = mysqldb.@O@
DBDRIVER_SRCS = mysqldb.c

DBDRIVER_INCLUDES = -I'/usr/include/mysql'

DBDRIVER_LIBS = -L'/usr/lib/mysql' -lmysqlclient -lz -lcrypt -lnsl -lm -lc -lnss_files -lnss_dns -lresolv -lc -lnss_files -lnss_dns -lresolv

 

#如果是x64的机器，需要修改/usr/lib64

 

In bind9/bin/named/main.c

add an include to mysqldb.h (e.g. #include "mysqldb.h") Then you must register the driver in setup(), by adding mysqldb_init(); before the call to ns_server_create().

 

Unregistration should be in cleanup(), by adding the call mysqldb_clear(); after the call to ns_server_destroy().

 

查找 xxdb_init();

在 注释文件 xxdb_init();

下添加 mysqldb_init();

然后查找查找 xxdb_clear();

再下面添加mysqldb_clear();

修改完后wq 保存退出，然后开始编译安装

./configure --enable-threads --prefix=/opt/bind9

cd /opt/bind9

/opt/bind9/sbin/rndc-confgen > /opt/bind9/etc/rndc.conf

将生产的

key "rndc-key" {
algorithm hmac-md5;
secret "?????????????????";
};
controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};

copy到named.conf文件

例如

options {
 
        directory "/var/cache/bind";
 
        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk.  See
 
        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders. 
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.
 
        // forwarders {
        //      0.0.0.0;
        // };
 
        auth-nxdomain no;    # conform to RFC1035
        listen-on-v6 { any; };
 
        allow-recursion { any; };
        allow-query { any; };
        recursion yes;
};
 
key "rndc-key" {
        algorithm hmac-md5;
        secret "9OTliFcI9vkDlNuDws5IVA==";
};
 
controls {
        inet 127.0.0.1 port 953
        allow { 127.0.0.1; } keys { "rndc-key"; };
};

编辑named.conf

zone "mydomain.com" {
  type master;
  notify no;
  database "mysqldb dbname tablename hostname user password";
};

 

CREATE TABLE mydomain (
  name varchar(255) default NULL,
  ttl int(11) default NULL,
  rdtype varchar(255) default NULL,
  rdata varchar(255) default NULL
) TYPE=MyISAM;

 

INSERT INTO mydomain VALUES ('mydomain.com', 259200, 'SOA', 'mydomain.com. 200309181 28800 7200 86400 28800');
INSERT INTO mydomain VALUES ('mydomain.com', 259200, 'NS', 'ns0.mydomain.com.');
