DNS域名解析服务（二）
作者：互联网
1、构建缓存域名服务器
[root@localhost ~]# vi /etc/named.conf
"/etc/named.conf" 18L, 430C
options {
listen-on port 53 { 192.168.66.13; };
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";
recursing-file "/var/named/data/named.recursing";
secroots-file "/var/named/data/named.secroots";
allow-query { any; };
recursion yes;
};
zone "." IN {
type hint;
file "named.ca";
};
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ :wq "/etc/named.conf" 18L, 430C written
2、构建主从域名服务器
所有服务器：
iptables -F
systemctl stop firewalld
setenforce 0
配置yum
主服务器：
[root@localhost ~]# yum -y install bind
[root@localhost ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.200.111
nameserver 192.168.200.112
[root@localhost ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.111 ns1.crushlinux.com
192.168.200.112 ns2.crushlinux.com
[root@localhost ~]# cat /etc/named.conf
options {
directory "/var/named";
};
zone "crushlinux.com" IN {
type master;
file "crushlinux.zheng";
allow-transfer { 192.168.200.112; };
};
zone "200.168.192.in-addr.arpa" IN {
type master;
file "crushlinux.fan";
allow-transfer { 192.168.200.112; };
};
[root@localhost ~]#
[root@localhost ~]# cat /var/named/crushlinux.zheng
