linux下智能DNS配置过程(1)

一、DNS服务器安装

1、 软件列表

BIND 9.3.2

ftp://ftp.isc.org/isc/bind9/9.3.2/bind-9.3.2.tar.gz

ftp://ftp.isc.org/isc/bind9/9.4.0a6/bind-9.4.0a6.tar.gz

2、 安装BIND 9

安装BIND9：

# tar zxvf bind-9.3.2.tar.gz

# cd bind-9.3.2

# ./configure --prefix=/usr/local/named --disable-ipv6

# make && make install

建立BIND用户：

# groupadd bind

# useradd -g bind -d /usr/local/named -s /sbin/nologin bind

创建配置文件目录：

# mkdir –p /usr/local/named/etc

# chown bind:bind /usr/local/named/etc

# chmod 700 /usr/local/named/etc

二、named.conf的配置

创建主要的配置文件：

# vi /usr/local/named/etc/named.conf
