Points for attention in the use of self-contained BIND under Linux system

Default settings for BIND

/ etc/named.conf-profile

/ etc/sysconfig/named-whether to start chroot and additional parameters are controlled by this file

/ var/named/-- Database files are placed in this directory by default

/ var/run/named-- named this defaults to placing pid-file in this directory when the program is executed

You can view the directory specified by chroot by viewing / etc/sysconfig/named

# vi / etc/sysconfig/named

ROOTDIR=/var/named/chroot

In this way, all the information required for the relevant procedures of bind will be in:

/ var/named/chroot/etc/named.conf

/ var/named/chroot/var/named/zone_file1

/ var/named/chroot/var/named/zone_file...

/ var/named/chroot/var/run/named/...

However, you can still use / etc/named.conf to set your DNS

Because the system will actively link / var/named/chroot/etc/named.conf to / etc/named.conf for you.

Summary of DNS servers:

A > the main profile is / etc/named.conf

B > each forward solution and inverse solution requires a file, and the file name is set by / etc/named.conf

C > the current BIND program has already implemented chroot. You can refer to / etc/sysconfig/named.

D > when querying DNS, if you don't have a database, go to root (. ) or forwarders host query

The erection of e > DNS server requires the authorization of the upper DNS to become a legitimate DNS server, otherwise it can only be internal.

It is important to check the information in / var/log/messages whether f > named starts successfully.
