搭建dns服务器

一、安装DNS服务

1.安装环境

• 192.168.2.175

• 关闭SELinux和防火墙

• 关闭libvirtd服务

2.步骤

安装unbound

yum install unbound -y

修改配置
vi /etc/unbound/unbound.conf

interface: 0.0.0.0
access-control: 0.0.0.0/0 allow
username: ""
logfile: "/var/log/unbound.log"

添加映射
vi /etc/unbound/local.d/dq.conf

local-data: "xian.hbisdt.com   IN      A       192.168.2.67"

加载配置

sudo unbound-control reload

二、安装反向代理服务器

1.安装nginx

cd /usr/soft
mkdir nginx
wget http://nginx.org/download/nginx-1.13.7.tar.gz
tar -xvf nginx-1.13.7.tar.gz
./configure --prefix=/usr/soft/nginx
make
make install

2.修改配置

vi /usr/soft/nginx/conf/nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  xian.hbisdt.com;

        location / {
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-NginX-Proxy true;
            proxy_pass http://192.168.2.67:8081;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

三、添加新映射

1.修改nginx，添加新的server配置

服务器地址：192.168.2.63 root 123456

vi /usr/soft/nginx/conf/nginx.conf

    server {
        listen       80;
        server_name  xian.dstore.com; //此处为域名

        location / {
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-NginX-Proxy true;
            proxy_pass http://192.168.2.74:8481; //此处为转发地址
        }
    }

加载nginx配置

/usr/soft/nginx/sbin/nginx -s reload

2.添加dns映射

服务器地址：192.168.2.175 root 123456

vi /etc/unbound/local.d/dq.conf

local-data: "xian.dstore.com   IN      A       192.168.2.63"

加载配置即可

sudo unbound-control reload

3.Linux 修改服务器DNS配置

vi /etc/resolv.conf

nameserver 192.168.2.175
