Oracle Linux 7.1如何配置DNS服务

2023-04-09 03:29:00 linux 服务 配置

如果你想要在Oracle Linux 7.1上配置DNS服务,那么你首先需要安装bind。你可以使用yum来安装它:

yum install bind

安装完成后,你需要编辑/etc/named.conf文件来配置DNS服务。你需要确保在文件中包含以下内容:

options {

listen-on port 53 { 127.0.0.1; };

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";

allow-query { any; };

recursion yes;

dnssec-enable yes;

dnssec-validation yes;

dnssec-lookaside auto;

/* Path to ISC DLV key */

bindkeys-file "/etc/named.iscdlv.key";

managed-keys-directory "/var/named/dynamic";

};

logging {

channel default_debug {

file "data/named.run";

severity dynamic;

};

};

zone "." IN {

type hint;

file "named.ca";

};

include "/etc/named.rfc1912.zones";

include "/etc/named.root.key";

接下来,你需要为你的域名创建一个区域文件。例如,如果你的域名是example.com,那么你的区域文件应该位于/var/named/example.com.db。区域文件应包含以下内容:

$TTL 86400

@ IN SOA ns1.example.com. root.example.com. (

2016071401 ;Serial

3600 ;Refresh

1800 ;Retry

604800 ;Expire

86400 ;Minimum TTL

)

;

@ IN NS ns1.example.com.

@ IN NS ns2.example.com.

@ IN A 192.168.1.100

ns1 IN A 192.168.1.100

ns2 IN A 192.168.1.101

www IN A 192.168.1.100

最后,你需要启动DNS服务:

systemctl start named

如果一切顺利,你应该能够在你的服务器上运行DNS服务了。
