mydns安装配置

        远程下载

        rpm包下载

1.因为mydns依赖mysql，所以需要先安装mysql。

1
yum install -y mysql-server

2 安装mydns

1
2
wget  http://www.lishiming.net/data//a ... ql-1.1.0-1.i386.rpm
rpm -ivh mydns-mysql-1.1.0-1.i386.rpm

3.创建库和表

mysql -uroot  -e "create database mydns"
mysql -uroot mydns
mysql> CREATE TABLE `soa` (   `id` int(10) unsigned NOT NULL auto_increment,   `origin` char(255) default NULL,   `ns` char(255) default NULL,   `mbox` char(255) default NULL,   `serial` int(10) unsigned default '1',   `refresh` int(10) unsigned default '28800',   `retry` int(10) unsigned default '7200',   `expire` int(10) unsigned default '604800',   `minimum` int(10) unsigned default '86400',   `ttl` int(10) unsigned default '86400',   `xfer` char(255) default NULL,   PRIMARY KEY  (`id`),   UNIQUE KEY `origin` (`origin`) ) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=gbk;
mysql>  CREATE TABLE `rr` (   `id` int(10) unsigned NOT NULL auto_increment,   `zone` int(10) unsigned NOT NULL,   `name` char(64) default NULL,   `type` enum('A','AAAA','CNAME','HINFO','MX','NAPTR','NS','PTR','RP','SRV','TXT') default NULL,   `data` char(128) default NULL,   `aux` int(10) unsigned NOT NULL,   `ttl` int(10) unsigned NOT NULL default '600',   `inter` tinyint(3) unsigned NOT NULL default '1',   `intra` tinyint(3) unsigned NOT NULL default '1',   PRIMARY KEY  (`id`),   KEY `name` (`name`),   KEY `rr` (`zone`,`name`,`type`,`data`) ) ENGINE=MyISAM AUTO_INCREMENT=1437896 DEFAULT CHARSET=gbk;

4.创建第一个zone

mysql> use mydns
mysql> insert into soa (id, origin,ns,mbox,serial,refresh,retry,expire,minimum,ttl) values(1,'abc.com.', 'ns.abc.com.',  'root.aminglinux.com', 1, 28800, 7200, 604800, 86400, 86400);
mysql> insert into rr values(1, 1, 'www', 'A', '1.1.1.1', 0, 1, 1, 1, 1);
