How to configure a simple DNS server ?
1 Install the DNS server packages
On Red Hat Enterprise Linux 5,
-------------------------------------------------
# yum install bind bind-chroot caching-nameserver
On Red Hat Enterprise Linux 6-------------------------------------------------
# yum install bind bind-chroot
2 Edit the configure file
Go to the configure directory, and you can see some files and one end of conf and one end of zones.
For RHEL 5, the configuration files have been placed there.
-------------------------------------------------
# cd /var/named/chroot/etc/-------------------------------------------------
# ls
-------------------------------------------------
localtime named.caching-nameserver.conf named.rfc1912.zones rndc.key
For RHEL 6, you need copy the sample files to the specific directory.
-------------------------------------------------
# cd /var/named/chroot/etc/-------------------------------------------------
# cp /usr/share/doc/bind-9.7.3/sample/etc/* .
Modify named.caching-nameserver.conf with the content below: (On RHEL 6, please modify the named.conf, all the configuration options are the same)
-------------------------------------------------
options {
-------------------------------------------------
listen-on port53 { 127.0.0.1; 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";
-------------------------------------------------
allow-query { localhost; any; };
-------------------------------------------------allow-query-cache { localhost; any; };
-------------------------------------------------
};
-------------------------------------------------
