Oracle Linux 7.1如何配置DNS服务
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。
