################################分割线 构建主域名服务器###########################
(1) 确定DNS服务器与需要解析的主机名和IP地址
DNS服务器:server01.linuxidc.com-->192.168.1.102
www服务器:>192.168.1.102
邮件服务器:mail.linuxidc.com-->192.168.1.105
主域服务器:ns1.linuxidc.com-->192.168.1.102
从域服务器:ns2.linuxidc.com-->192.168.1.103
(2) 创建正向区域和反向区域
vi /var/named/chroot/etc/named.conf
options
{
listen-on port 53 { 192.168.1.102; };
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 { 192.168.1.0/24; };
recursion yes;
};
zone "linuxidc.com" IN {
type master;
file "net.zx";
};
zone "1.168.192.in-addr.arpa" IN {
type master;
file "net.fx";
};
(3) 创建正向和反向区域文件
通过参考localhost域的正反向区域文件创建区域文件
cd /var/named/chroot/var/named
cp -p localdomain.zone benet.zx
cp -p named.local benet.fx
vi benet.zx
