RedHat Linux AS 5.3 下DNS的配置与RedHat Linux AS 4.5的有很多地方不太一样,这里我把在RedHat Linux AS 5.3 下DNS配置步骤做了一个笔记,操作如下:

一、检查BIND包,缺少bind、bind-chroot包


二、利用YUM源,安装BIND包

1、 配YUM源

[root@mydb ~]# mount /dev/cdrom /mnt

mount: block device /dev/cdrom is write-protected, mounting read-only

[root@mydb ~]# vi/etc/yum.repos.d/update.repo

[update]name=updatebaseurl=file:///mnt/Servergpgcheck=0enabled = 1

2、 安装bind包

[root@mydb ~]# yum list

[root@mydb~]# yum install bind

Loaded plugins: rhnplugin, securityThis system is not registered with RHN.RHN support will be disabled.Setting up Install ProcessParsing package install argumentsResolving Dependencies--> Running transaction check---> Package bind.x86_64 30:9.3.4-10.P1.el5 set to be updated--> Finished Dependency ResolutionDependencies Resolved========================================================================================================================== Package                 Arch                      Version                                Repository                 Size==========================================================================================================================Installing: bind                    x86_64                    30:9.3.4-10.P1.el5                     update                    961 kTransaction Summary==========================================================================================================================Install      1 Package(s)         Update       0 Package(s)         Remove       0 Package(s)         Total download size: 961 kIs this ok [y/N]: yDownloading Packages:Running rpm_check_debugRunning Transaction TestFinished Transaction TestTransaction Test SucceededRunning Transaction  Installing     : bind                                              [1/1] Installed: bind.x86_64 30:9.3.4-10.P1.el5Complete!

[root@mydb~]# yum install bind-chroot

Loaded plugins: rhnplugin, securityThis system is not registered with RHN.RHN support will be disabled.Setting up Install ProcessParsing package install argumentsResolving Dependencies--> Running transaction check---> Package bind-chroot.x86_64 30:9.3.4-10.P1.el5 set to be updated--> Finished Dependency ResolutionDependencies Resolved========================================================================================================================== Package                      Arch                    Version                               Repository               Size==========================================================================================================================Installing: bind-chroot                  x86_64                  30:9.3.4-10.P1.el5                    update                   42 kTransaction Summary==========================================================================================================================Install      1 Package(s)         Update       0 Package(s)         Remove       0 Package(s)         Total download size: 42 kIs this ok [y/N]: yDownloading Packages:Running rpm_check_debugRunning Transaction TestFinished Transaction TestTransaction Test SucceededRunning Transaction  Installing     : bind-chroot                                       [1/1] Installed: bind-chroot.x86_64 30:9.3.4-10.P1.el5Complete!

3、 检查安装的BIND包,Ok了!




[root@mydb ~]# service named status

rndc: connect failed: 127.0.0.1#953: connection refused

named is stopped

说明DNS没有配好,接下来就开始配置DNS。



三、配置DNS

1、 安装caching-nameserver

[root@mydb~]# yum install caching-nameserver

Loaded plugins: rhnplugin, securityThis system is not registered with RHN.RHN support will be disabled.Setting up Install ProcessParsing package install argumentsResolving Dependencies--> Running transaction check---> Package caching-nameserver.x86_64 30:9.3.4-10.P1.el5 set to be updated--> Finished Dependency ResolutionDependencies Resolved========================================================================================================================== Package                            Arch                   Version                             Repository            Size==========================================================================================================================Installing: caching-nameserver                 x86_64                 30:9.3.4-10.P1.el5                  base                  58 kTransaction Summary==========================================================================================================================Install      1 Package(s)         Update       0 Package(s)         Remove       0 Package(s)         Total download size: 58 kIs this ok [y/N]: yDownloading Packages:Running rpm_check_debugRunning Transaction TestFinished Transaction TestTransaction Test SucceededRunning Transaction  Installing     : caching-nameserver                                [1/1] Installed: caching-nameserver.x86_64 30:9.3.4-10.P1.el5Complete!

2、 安装完成会在/etc/下生成named.caching-nameserver.conf,查看其内容如下:

[root@mydb~]# cat /etc/named.caching-nameserver.conf

//// named.caching-nameserver.conf//// Provided by Red Hat caching-nameserver package to configure the// ISC BIND named(8) DNS server as a caching only nameserver // (as a localhost DNS resolver only). //// See /usr/share/doc/bind*/sample/ for example named configuration files.//// DO NOT EDIT THIS FILE - use system-config-bind or an editor// to create named.conf - edits to this file will be lost on // caching-nameserver package upgrade.//options {        listen-on port 53 { 127.0.0.1; };        listen-on-v6 port 53 { ::1; };        directory       "/var/named";        dump-file       "/var/named/data/cache_dump.db";        statistics-file "/var/named/data/named_stats.txt";        memstatistics-file "/var/named/data/named_mem_stats.txt";        // Those options should be used carefully because they disable port        // randomization        // query-source    port 53;        // query-source-v6 port 53;        allow-query     { localhost; };};logging {        channel default_debug {                file "data/named.run";                severity dynamic;        };};view localhost_resolver {        match-clients      { localhost; };        match-destinations { localhost; };        recursion yes;        include "/etc/named.rfc1912.zones";};

3、拷贝/etc/named.caching-nameserver.conf到/var/named/chroot/etc/named.conf

[root@mydb ~]# cp /etc/named.caching-nameserver.conf /var/named/chroot/etc/named.conf



4、 编辑/var/named/chroot/etc/named.conf

[root@mydb ~]# vi/var/named/chroot/etc/named.conf

options {        listen-on port 53 { 0.0.0.0/0; };        directory       "/var/named";        dump-file       "/var/named/data/cache_dump.db";        statistics-file "/var/named/data/named_stats.txt";        memstatistics-file "/var/named/data/named_mem_stats.txt";        // Those options should be used carefully because they disable port        // randomization        // query-source    port 53;        // query-source-v6 port 53;        allow-query     { any; };       //allow-query-cache    { any; };};logging {        channel default_debug {                file "data/named.run";                severity dynamic;        };};#view localhost_resolver {#       match-clients      { localhost; };#       match-destinations { localhost; };#       recursion yes;#       include "/etc/named.rfc1912.zones";#};## ----添加以下这一段zone "example.com."{         type master;         file "example.file";};


5、 修改named.conf权限

[root@mydb~]# cd /var/named/chroot/etc/

[root@mydbetc]# ll

total 20

-rw-r--r--1 root root 405 Sep 26 22:10 localtime

-rw-r-----1 root named 1195 Jan 6 2009 named.caching-nameserver.conf

-rw-r-----1 root root 1371 Nov 27 10:19 named.conf

-rw-r-----1 root named 955 Jan 6 2009named.rfc1912.zones

-rw-r-----1 root named 113 Nov 27 09:53 rndc.key

[root@mydbetc]# chown .named named.conf

[root@mydbetc]# ll

total 20

-rw-r--r--1 root root 405 Sep 26 22:10 localtime

-rw-r-----1 root named 1195 Jan 6 2009 named.caching-nameserver.conf

-rw-r-----1 root named 1371 Nov 27 10:19 named.conf

-rw-r-----1 root named 955 Jan 6 2009named.rfc1912.zones

-rw-r----- 1 root named 113 Nov 27 09:53 rndc.key



6、 配域名

root@mydbnamed]# pwd

/var/named/chroot/var/named

[root@mydbnamed]# ls -l

total 36

drwxrwx---2 named named 4096 Aug 26 2004 data

-rw-r-----1 root named 198 Jan 6 2009 localdomain.zone

-rw-r-----1 root named 195 Jan 6 2009 localhost.zone

-rw-r-----1 root named 427 Jan 6 2009 named.broadcast

-rw-r-----1 root named 1892 Jan 6 2009named.ca

-rw-r-----1 root named 424 Jan 6 2009 named.ip6.local

-rw-r-----1 root named 426 Jan 6 2009 named.local

-rw-r-----1 root named 427 Jan 6 2009 named.zero

drwxrwx--- 2 named named 4096 Jul 27 2004 slaves

[root@mydb named]# cplocaldomain.zone example.file

7、 编辑example.file

[root@mydb named]# vi /var/named/chroot/var/named/example.file

$TTL    86400@               IN SOA  guoyjoe.example.com. root (                                        42              ; serial (d. adams)                                        3H              ; refresh                                        15M             ; retry                                        1W              ; expiry                                        1D )            ; minimum                IN NS           guoyjoe.example.comguoyjoe         IN A            192.168.153.129mydb            IN A            192.168.153.129

四、启动DNS服务

[root@mydbnamed]# service named restart

Stoppingnamed: [ OK ]

Starting named: [ OK ]


五、客户端的DNS指定

[root@mydb ~]# more /etc/resolv.conf
; generated by /sbin/dhclient-script
search localdomain
nameserver 192.168.153.129
