需求:在内网已部署一个苹果CMS,但每次访问都要通过IP很不方便,需要转变为用域名访问
方法一:
给每个需要访问该网站的人添加一条hosts记录;如果只是几个人这方法的确很快,但是如果上百人甚至上千人一个个去添加hosts显然是不理智的行为
方法二:在内网搭建一个DNS服务器添加解析记录即可
IP地址:192.168.111.68
环境:
[root@DNS-Server named] CentOS Linux release 7.7.1908 (Core)
安装DNS软件
yum install vim bind*-y
修改配置文件
vim /etc/named.conf
配置域名解析
注:添加的内容可直接填写在/etc/named.conf或填写/etc/named.rfc1912.zones或自定义;本次实验填写在/etc/named.rfc1912.zones中。
vim /etc/named.rfc1912.zones
创建正向解析文件
vim virgo.com.zone $TTL 1D @ IN SOA virgo.com. root.virgo.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum @ IN NS dns.virgo.com. dns IN A 192.168.111.68 //DNS服务器地址 www IN A 192.168.111.58 //视频服务器IP地址
由于暂时用不到反向解析,暂且跳过
重启服务:systemctl restart named
客户端配置DNS:
登录苹果CMS后台配置域名;www.virgo.com
客户端刷新DNS缓存:
测试访问即可
思考:上述搭建DNS仅是内网使用,如果查询的域名在内网DNS并没指向怎么办呢?添加转发地址即可。
options { listen-on port 53 { any; }; //默认是any,表示允许所有网段的主机。可以改成自己所在的内网网段 listen-on-v6 port 53 { ::1; }; directory "/var/named"; //定义named的固定工作路径 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; }; //表示接收所有网段 recursion yes; forward first; //下面这两行配置很重要,这个配置后,当客户端采用我们自己配置的内网DNS的NS服务器后,当访问别的网站,内网NS解析不了的就转发给8.8.8.8的DS服务器解析,保证能正常上网。 forwarders { 223.5.5.5; //阿里云的DNS服务器 223.6.6.6; 8.8.8.8; 8.8.4.4; }; };

拓展:搭配nginx代理服务
DNS配置文件:
注:192.168.107.130为DNS服务器、192.168.107.115为nginx服务器
$TTL 1D @ IN SOA virgo.com. root.virgo.com. ( 0 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum @ IN NS dns.virgo.com. dns IN A 192.168.107.130 j IN A 192.168.107.115 s IN A 192.168.107.115 v IN A 192.168.107.115 u IN A 192.168.107.115 vm IN A 192.168.107.115 z IN A 192.168.107.115
nginx配置文件:
配置文件中一个server表示一个服务
worker_processes 1; pid logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name j.virgo.com; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; location / { proxy_pass http://192.168.111.180;} error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name s.virgo.com; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; location / { proxy_pass http://192.168.107.91;} error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name v.virgo.com; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; location / { proxy_pass http://192.168.107.114/;} error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name z.virgo.com; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; location / { proxy_pass http://192.168.107.119/zabbix/;} error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } server { listen 80; server_name vm.virgo.com; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; location / { proxy_pass https://192.168.107.112;} error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } }
