DNS for Linux Network Services

Linux Network Service-DNS-Linux Enterprise Application-Linux server application information. For details, refer to the following section. Preparation:
Attach the optical drive: mount/dev/cdrom/mnt/cdrom/
To replace the disc, uninstall the optical drive: umount/mnt/cdrom or eject.
Decompress the bind package: tar xzf bind-9.2.3.tar.gz-C/usr/local/src/
Compile, configure, and install: cd/usr/local/src/bind-9.2.3
./Configure -- prefix =/usr/local/bind & make install
Put the RedHat 9 second disc (RedHat AS 4 first disc) of the installation disk in the drive, find the caching-nameserver-7.3-3.noarch.rpm
Run rpm ivh caching-nameserver-7.3-3.noarch.rpm -- nodeps (no dependency)
Generate the rndc. key File:/usr/local/bind/sbin/rndc-confgen>/etc/rndc. conf
Mv/etc/rndc. conf/etc/rndc. key
Edit/etc/rndc. key
Delete content other than the first four lines !!
Configuration file:
Main configuration file:/etc/named. conf
Configuration area file
Switch to the bind installation directory/usr/local/bind/sbin /.
Check the main Configuration File Syntax command:
./Named-checkconf/etc/named. conf
Check the region file:
./Named-checkzone guoyuan.com/var/named/0.168.192
./Named-checdzone guoyuan.com/var/named/guoyuan.com
Check whether there are any errors. If there are no errors, run the bind service.
Run:/usr/local/bind/sbin/named-c/etc/named. conf
If you do not enter the-c parameter, all named parameters are displayed. For example
[Root @ host sbin] #./named/etc/named. conf
Usage: named [-c conffile] [-d debuglevel] [-f |-g] [-n number_of_cpus]
[-P port] [-s] [-t chrootdir] [-u username]

Troubleshooting,
Run/usr/local/bind/sbin/named-c/etc/named. conf
View process: ps-aux | grep named
View port: netstat-an | grep 53

Note:
1. Set NS record (required), mx record, and A record CNAME record for the region File
The configuration file is as follows:
$ TTL 86400
@ In soa test root.guoyuan.com .(
42; serial (d. adams)
3 H; refresh
15 M; retry
1 W; expiry
1D); minimum
In ns test.guoyuan.com.
Test.guoyuan.com. in a 192.168.0.26
Ftp in a 192.168.0.24
Webserver in a 192.168.0.3
In a 192.168.0.26
In a 192.168.4.2
Www in cname webserver
Mail in a 192.168.0.26
@ In mx 5 mail
Test1.guoyuan.com. in a 192.168.2.4
If you want to add domain names in batches, such as station100.guoyuan.com ---station200.guoyuan.com, add the following statement to the region file:
$ Generate 100-200 station $ .guoyuan.com. A 192.168.0. $

2. If named is automatically loaded upon startup:
Use vi to add/usr/local/bind/sbin/named-c/etc/named. conf to the/etc/rc. d/rc. local file.
Or
Input echo "/usr/local/bind/sbin/named-c/etc/named. conf">/etc/rc. d/rc. local
The two formats are Xiangyang/etc/rc. d/rc. write "/usr/local/bind/sbin/named-c/etc/named. conf "This statement!
