1、一个只缓存名字服务器
下列配置样例合适用于一个只缓存名字服务器,用于一个公司的内部客户端。通过使用
allow-query 选项,所有外来客户端的请求都被拒绝。另外一个选择是,使用合适的防火墙规
则也可以取得同样的效果。
// Two corporate subnets we wish to allow queries from.
acl corpnets { 192.168.4.0/24; 192.168.7.0/24; };
options {
directory "/etc/namedb"; // Working directory
allow-query { corpnets; };
};
// Provide a reverse mapping for the loopback address 127.0.0.1
zone "0.0.127.in-addr.arpa" {
type master;
file "localhost.rev";
notify no;
};
2、一个只权威名字服务器
这个样例配置是给只作权威服务器的,在这里服务器作“example.com”的主服务器和其子域
“eng.exmaple.com”的辅服务器。
options {
directory "/etc/namedb"; // Working directory
allow-query-cache { none; }; // Do not allow access to cache
allow-query { any; }; // This is the default
recursion no; // Do not provide recursive service
};
// Provide a reverse mapping for the loopback address 127.0.0.1
zone "0.0.127.in-addr.arpa" {
type master;
file "localhost.rev";
notify no;
};
// We are the master server for example.com
zone "example.com" {
type master;
file "example.com.db";
// IP addresses of slave servers allowed to transfer example.com
allow-transfer {
192.168.4.14;
192.168.5.53;
};
};
// We are a slave server for eng.example.com
zone "eng.example.com" {
type slave;
file "eng.example.com.bk";
// IP address of eng.example.com master server
masters { 192.168.4.12; };
};
3、Bind智能解析(包括主辅同步)
3.1下载所需软件
# wget ftp://ftp.isc.org/isc/bind9/9.3.2/bind-9.3.2.tar.gz
3.2安装BIND 9
安装BIND9:
# tar zxvf bind-9.3.2.tar.gz
# cd bind-9.3.2
# ./configure --prefix=/usr/local/named --disable-ipv6 --enable-threads
--enable-threads 开启多线程,更多选项可使用./configure --help参数查看
# make && make install
3.3配置BIND9
建立BIND用户:
# groupadd bind
# useradd -g bind -d /usr/local/named -s /sbin/nologin bind
创建配置文件目录:
# mkdir –p /usr/local/named/etc
# chown bind:bind /usr/local/named/etc
# chmod 700 /usr/local/named/etc
生成rndc控制命令的key文件:
# /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
编辑named.conf主配置文件:
# vi /usr/local/named/etc/named.conf
# # # # # # # # # # # # # # # named.conf# # # # # # # # # # # # # #
acl "trust-lan" { any; };
options {
directory "/usr/local/named/etc/"; //bind文件的配置目录
pid-file "/var/run/named/named.pid";
version "0.0.0";
allow-query { any; };
};
logging {
channel warning { file "/var/log/named/dns_warnings" versions 3 size 1240k;
severity warning;
print-category yes;
print-severity yes;
print-time yes;
};
channel general_dns
{ file "/var/log/named/dns_logs" versions 3 size 1240k;
severity info;
print-category yes;
print-severity yes;
print-time yes;
};
category default { warning; };
category queries { general_dns; };
};
include "acl/telecom.acl"; //include电信ip段列表
view "view_telecom" {
match-clients { telecom; };
zone "." {
type hint;
file "named.root";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.IN-ADDR.ARPA" {
type master;
file "localhost.rev";
};
include "master/telecom.def";
};
view "view_any" {
match-clients { any; };
zone "." {
type hint;
file "named.root";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.IN-ADDR.ARPA" {
type master;
file "localhost.rev";
};
include "master/cnc.def";
};
# # # # # # # # # # # end# # # # # # # # #
创建acl列表:
# mkdir acl
# vi telecom.acl
acl "telecom" {
58.154.0.0/15;
58.192.0.0/12;
59.64.0.0/12;
116.13.0.0/16;
收集到的网通的地址段
};
创建PID和日志文件:
# mkdir /var/run/named/&&chmod 777 /var/run/named/
# chown bind:bind /var/run/named/
# mkdir /var/log/named/
# touch /var/log/named/dns_warnings
# touch /var/log/named/dns_logs
# chown bind:bind /var/log/named
添加 mysqldb_init();
找到
添加 mysqldb_clear();
loading zone: creating database: failure错误处理
如果出现这个问题,那说明bind sdb驱动和mysql链接出现了问题,诸如密码错误,dns没有建立,引用/tmp/mysql.sock错误等等.这个问题出现之后,你需要在mysqldb.c中加入一些调试信息:
在mysqldb.c的db_connect函数中修改:
引用
if (mysql_real_connect ( &dbi->conn, dbi->host, dbi->user, dbi->passwd, dbi->database, 0, NULL, 0 ))
{
fprintf(stderr,"\nconnect successfully .............. \n");
return (ISC_R_SUCCESS);
}
else
{
fprintf(stderr,"\nconnect fail:%s , host %s,user %s,passwd %s,db %s,port %d ...................\n",mysql_error(&dbi->conn),dbi->host,dbi->user,dbi->passwd,dbi->database);
return (ISC_R_FAILURE);
}
这样方便得到出错信息.然后根据出错信息调试mysql,使bind sdb能成功链接mysql.
4.5编译安装、配置bind
# ./configure --prefix=/usr/local/named --enable-threads #--enable-threads开启多线程处理能力
# make
# make install
# cd /usr/local/named
# mkdir etc 建立etc目录
# sbin/rndc-confgen > etc/rndc.conf 生成rndc控制命令的key文件
生成rndc key
# cd etc
# tail -10 rndc.conf | head -9 | sed s/#\ //g > named.conf 从rndc.conf文件中提取named.conf用的key自动在/usr/local/named/etc 生成named,conf文件
建立localhost.zone文件
# vi localhost.zone
$TTL 86400
$ORIGIN localhost.
@ 1D IN SOA @ root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS @
1D IN A 127.0.0.1
建立named.local文件
# vi named.local
$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.
1 IN PTR localhost.
dig命令直接生成named.root文件
# dig > named.root
配置 named.conf
增加如下内容:
controls {
inet 127.0.0.1 port 953
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 9.31 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
24,9
};
//
// a caching only nameserver config
//
zone "." IN {
type hint;
file "named.root";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "mydomain.com" {
type master;
database "mysqldb dnsdb mydomain localhost root passwd"; 配置你的数据库名,表名,MYSQL主机,MYSQL用户,MYSQL密码
};
zone "19.202.220.in-addr.arpa" {
type master;
database "mysqldb dnsdb ptr localhost root passwd"; 配置你的数据库名,表名,MYSQL主机,MYSQL用户,MYSQL密码
};
BIND安装完成!
4.6建立bind数据库
我是用MYSQLADMIN来建立数据库的和倒数据的,APACHE下安装MYSQLADMIN我这里就不详细讲了。
正向解析数据库mydomain表结构
>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;
以下是正向解析示范可以直接倒入
>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.');
>INSERT INTO mydomain VALUES ('mydomain.com', 259200, 'NS', 'ns1.mydomain.com.');
>INSERT INTO mydomain VALUES ('mydomain.com', 259200, 'MX', '10 mail.mydomain.com.');
>INSERT INTO mydomain VALUES ('w0.mydomain.com', 259200, 'A', '192.168.1.1');
>INSERT INTO mydomain VALUES ('w1.mydomain.com', 259200, 'A', '192.168.1.2');
>INSERT INTO mydomain VALUES ('mydomain.com', 259200, 'Cname', 'w0.mydomain.com.');
>INSERT INTO mydomain VALUES ('mail.mydomain.com', 259200, 'Cname', 'w0.mydomain.com.');
>INSERT INTO mydomain VALUES ('ns0.mydomain.com', 259200, 'Cname', 'w0.mydomain.com.'
>INSERT INTO mydomain VALUES ('ns1.mydomain.com', 259200, 'Cname', 'w1.mydomain.com.');
>INSERT INTO mydomain VALUES ('', 259200, 'Cname', 'w0.mydomain.com.');
>INSERT INTO mydomain VALUES ('ftp.mydomain.com', 259200, 'Cname', 'w0.mydomain.com.');
反向解析数据库ptr表结构
>CREATE TABLE ptr (
>name varchar(255) default NULL,
>ttl int(11) default NULL,
>rdtype varchar(255) default NULL,
>rdata varchar(255) default NULL
>) TYPE=MyISAM;
以下是反向解析示范可以直接倒入
>INSERT INTO `ptr` VALUES ('19.202.220.in-addr.arpa', 17600, 'SOA', 'mydomain.com. 200309181 28800 7200 86400 28800');
>INSERT INTO `ptr` VALUES ('19.202.220.in-addr.arpa', 17600, 'NS', 'ns0.mydomain.com.');
>INSERT INTO `ptr` VALUES ('19.202.220.in-addr.arpa', 17600, 'NS', 'ns1.mydomain.com.');
>INSERT INTO `ptr` VALUES ('82.19.202.220.in-addr.arpa', 17600, 'PTR', 'mail.mydomain.');
--------------------------------------------------------------------------------数据库建立完成
启动你的BIND 测试BIND是否能正常工作
# /usr/local/named/sbin/named -c /usr/local/named/etc/named.conf &
然后在你WINDOWS机器上将这个配置了BIND的IP设置为DNS然后运行nslookup测试
如果出现证明反向解析正常
Default Server: mail.mydomain
Address: 220.202.19.2
>
如果PING w0.mydomain.com
解析地址为192.168.1.1 证明正向工作正常
结束语:
BIND + MYSQL 在增加A记录 MX记录 PTR记录都不需要从新启动BIND,每增加一个正向的解析域名都必须在named.conf正增加如下内容
zone "youname.com" {
type master;
database "mysqldb dnsdb mydomain localhost root passwd"; 配置你的数据库名,表名,MYSQL主机,MYSQL用户,MYSQL密码
};
