Rhel5 build secondary DNS

To create a DNS, first make sure that we have installed bind and caching-nameserver. caching-nameserver contains most of the bind configuration files. So I suggest you install it. First, create the primary DNS. First install. Rpm-ivhbind-9.3.3-7.el5.i386.rp build DNS first we need to determine that we have installed bind and caching-nameserver, caching-nameserver contains most of the bind configuration files. So I suggest you install it.
First, create the primary DNS. First install.
Rpm-ivh bind-9.3.3-7.el5.i386.rpm caching-nameserver-9.3.3-7.el5.i386.rpm
DNS has two major configuration files.
/Etc/named. caching-nameserver.conf and/etc/named. rfc1912.zones
1. First we configure/etc/named. caching-nameserver.conf
 
[Root @ localhost Server] # vim/etc/named. caching-nameserver.conf
// Caching-nameserver package upgrade.
//
Options {
// Listen-on port 53 {127.0.0.1;}; // comment out these parts; otherwise, the service cannot be provided externally.
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 {localhost;}; // comment out these items; otherwise, the service cannot be provided externally.
};
Logging {
Channel default_debug {
File "data/named. run ";
Severity dynamic;
};
};
View localhost_resolver {
// Match-clients {localhost;}; // comment out these parts; otherwise, the service cannot be provided externally.
// Match-destinations {localhost;}; // comment out these places; otherwise, the service cannot be provided externally.
Recursion yes;
"/Etc/named. caching-nameserver.conf" 36L, 1108C 34,2-9 84%
 
2. Add our region at the bottom of the configuration file/etc/named. rfc1912.zones.
 
Zone "aaa.com" IN {
Type master;
File "aaa.com ";
};
3. Create the aaa.com content in/var/named/
 
 
@ In soa ns.aaa.com. asd.asd.com .(
42; serial (d. adams)
3 H; refresh
15 M; retry
1 W; expiry
1D); minimum
In ns ns.aaa.com.
Ns in a 192.168.1.8
Www in a 192.168.1.1
In ns ns1.aaa.com.; here we must specify the Auxiliary
Ns1 in a 192.168.1.1; DNS address.
Then we start DNS
[Root @ localhost ~] # Service named restart
Then we configure the secondary DNS server.
The first step of configuration is the same, both are modifying/etc/named. caching-nameserver.conf
Then we configure/etc/named. rfc1912.zones
Add our region at the end of the configuration file
Zone "aaa.com" IN {
Type slave;
File "slaves/aaa.com"; the write permission is required for Region replication.
Masters {192.168.1.8 ;}; primary DNS address
};
If you like to use the named directory, change the permission of the named directory to 770.
