- 安装 ```shell yum install bind-chroot bind-utils -y ``` - 修改配置文件 ```shell vi /etc/named.conf options { # listen-on port 53 { any; }; listen-on port 53 { 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"; recursing-file "/var/named/data/named.recursing"; secroots-file "/var/named/data/named.secroots"; # allow-query { any; }; allow-query { any; }; /* - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion. - If you are building a RECURSIVE (caching) DNS server, you need to enable recursion. - If your recursive DNS server has a public IP address, you MUST enable access control to limit queries to your legitimate users.

IN { type hint; file "named.ca"; }; include "/etc/named.rfc1912.zones"; include "/etc/named.root.key"; ``` - 修改域名的区域文件 ```shell vi /etc/named.rfc1912.zones zone "xxx.com" IN { type master; file "xxx.com.zone"; allow-update { none; }; }; zone "131.168.192.in-addr.arpa" { type master; file "192.168.131.arpa"; allow-update { none; }; }; ``` - 设置正向解析文件 ```shell cd /var/named cp -a named.localhost xxx.com.zone $TTL 1D @ IN SOA xxx.com. root.xxx.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS ns.xxx.com. ns IN A 192.168.131.10 www IN A 192.168.131.10 ``` - 设置反向解析文件 ```shell cd /var/named cp -a named.loopback 192.168.131.arpa $TTL 1D @ IN SOA xxx.com. root.xxx.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum NS ns.xxx.com. ns A 192.168.131.10 10 PTR www.xxx.com. ``` - 验证 ```shell nslookup ```
