LAMP+Bind+phpMyAdmin带后台管理的动态DNS配置
有时有这样的需求,一个公司会有许多域名需要管理。而这些域名和ip的对应经常变化,后台的操作人员不是linux人。下面的文档将实现这个需求。
1.安装lamp环境
yum install mysql-server php* httpd
/etc/init.d/mysqld start
/etc/init.d/httpd start
2.安装bind服务
tar zxvf bind-9.9.5.tar.gz -C /usr/src/
./configure –prefix=/usr/local/named –with-dlz-mysql –without-ssl –enable-threads
make &&make install
3.配置bind服务及mysql数据库
配置bind:
/usr/local/named/sbin/rndc-confgen >/usr/local/named/etc/rndc.conf
cd /usr/local/named/etc/
tail -10 rndc.conf | head -9 | sed s/#\ //g >named.conf
vi named.conf ##在末尾添加如下内容
dlz "DLZ use MySQL" {
database "mysql
{host=127.0.0.1 dbname=named ssl=false user=named pass=123123}
{select zone from 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 from dns_records where zone = '$zone$' and host = '$record$'}";
};
注意:host=127.0.0.1不要写主机名不然会报错,dbname是数据库的名字,user指定数据用户,pass指定密码。select是用查询的sql语句,提供给客户查询解析。
创建数据库:
这是一数据库创建完成后导出的文件可以复制,用vi创建named.sql文件
[root@ns ~]# cat named.sql

[root@ns ~]#
创建数据named并给权限
mysqladm -uroot password 123123 ##给mysql root修改密码
mysql -uroot -p123123
create database named;
grant all on named.* to 'named'@'127.0.0.1' identified by '123123'; ##密码必须与named.conf中一致
flush privileges;
quit;
[root@ns ~]# mysql -uroot -p123123 - -database named <named.sql ##导入数据库
4.启动named服务
/usr/local/named/sbin/named -gc /usr/local/named/etc/named.conf &
netstat -uptln |grep named
[root@ns ~]# cat /etc/resolv.conf ##指定dns服务
search linuxfan.cn
nameserver 192.168.8.79
[root@ns ~]# /usr/local/named/bin/nslookup ns.linuxfan.cn
Server: 192.168.8.79
Address: 192.168.8.79#53
Name: ns.linuxfan.cn
Address: 192.168.8.79
测试成功。
5.额外的设置,安装phpmyadmin作为dns的后台管理,对于对数据库不是很懂的朋友,可以看看。
phpMyAdmin-3.3.10-all-languages.tar.gz软件包,注意要安装php5.3。如果是如果是php版本不是5.3及以上可使用phpmyadmin-2.11.11.3-all-languages.tar.gz安装。
命令如下:
tar zxvf phpmyadmin-3.3.10-all-languages.tar.gz -C /usr/src/
cd /usr/src/
mv phpMyAdmin-3.3.10-all-languages/ /var/www/html/phpmyadm
cd /var/www/html/phpmyadm
cp config.sample.inc.php config.inc.php ##建立配置文件
