RedHatCentOS build DNS server forward resolution

The following is a forward resolution (IP192.168.1.2 domain name is www.linuxidc.com) based on the RedHat5 or CentOS system. to ensure the construction is successful, do not miss any step. The following is a detailed step-by-step command to ensure the success! (For reverse resolution steps, refer to the next article) 1. install related software packages: follow the steps below for forward resolution based on RedHat 5 or CentOS system (IP192.168.1.2 domain name is www.linuxidc.com) to ensure successful construction, the following are detailed steps to execute commands one by one to 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
