RedHat CentOS build DNS server forward resolution

The following is a forward resolution based on RedHat 5 or CentOS System (IP192.168.1.2 domain name is www.linuxidc.com). To ensure successful construction, do not miss any step. The following is a detailed step-by-step command can also ensure success! (For reverse resolution steps, refer to the next article)

1. Install related software packages: to ensure smooth operation, follow these steps to delete and reinstall all software packages.

[Root @ server ~] # Rpm-qa | grep bind // view bind related software packages


[Root @ server ~] # Rpm-e 'rpm-qa | grep bind' -- nodeps // Delete related software packages
[Root @ server ~] # Mount/dev/cdrom/media // mount the system disk to/media/
[Root @ server media] # cd/media/Server // enter the/media/Server/directory
[Root @ server Server] # rpm-vih bind-* // reinstall the Software Package
[Root @ server Server] # rpm-vih caching-nameserver-9.3.3-7.el5.i386.rpm
[Root @ server Server] # service named start // restart the named service


2. Modify the master configuration file
[Root @ server Server] # cd/var/named/chroot/etc // enter the/var/named/chroot/etc/directory
[Root @ server etc] # vim named. caching-nameserver.conf // modify the master configuration file
----------------------------------------------------------------------
Options {
Listen-on port 53 {any ;}; // modify it to any
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 ";
Query-source port 53;
Query-source-v6 port 53;
Allow-query {any ;}; // modify it to any
};
Logging {
Channel default_debug {
File "data/named. run ";
Severity dynamic;
};
};
View localhost_resolver {
Match-clients {any ;}; // modify it to any
Match-destinations {any ;}; // modify it to any
Recursion yes;
Include "/etc/named. rfc1912.zones ";
};
----------------------------------------------------------------------

3. Modify the extension file of the Host Configuration File
[Root @ server etc] # vim named. rfc1912.zones // modify the host configuration file extension and add it in the last line
----------------------------------------------------------------------
Zone "linuxidc.com" IN {// IN can be unavailable
Type master; // type-Based Domain
File "linuxidc.com"; // Domain Configuration file
};
---------------------------------------------------------------------
4. Create a domain configuration file for linuxidc.com

[Root @ server etc] # cd/var/named/chroot/var/named // enter the/var/named/chroot/var/named/directory
[Root @ server named] # cp named. local linuxidc.com // copy the domain configuration file
[Root @ server named] # vim linuxidc.com
--------------------------------------------------------------------

--------------------------------------------------------------------
[Root @ server named] # bind-chroot-admin-s // automatically sets the group and permissions
[Root @ server named] # service named restart // restart the named service
5. test and verification

[Root @ localhost ~] # Nslookup // verify that the resolution is successful on the local machine
