實現DNS主從域，http虛擬主機跟用戶

DNS

域名解析是把域名指向網站空間IP，讓人們通過注冊的域名可以方便地訪問到網站的一種服務。IP地址是網絡上標識站點的數字地址，為了方便記憶，采用域名來代替IP地址標識站點地址。域名解析就是域名到IP地址的轉換過程。域名的解析工作由DNS服務器完成。

1、安裝dns服務器
[root@localhost ~]# yum -y install bind*
2、修改配置文件
在/etc/named.conf中：

 listen-on port 53 { any; };
  allow-query     { any; };

然后創建解析：
vim /etc/named.rfc1912.zones

zone "web1.com" IN {
    type master;
    file "data/web1.com.zone";
        }；

在/var/named/data/中創建web1.com.zone文件如下

$TTL 3H
@       IN SOA  web1.com. root (
                                        20180928 ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        IN   NS            @
        IN   A          192.168.159.130
www     IN   A          192.168.159.130

3.啟動named服務：

systemctl start named

ps -ef | grep named
顯示啟動成功

4 測試

[root@localhost ~]# nslookup 
> web1.com
Server:         192.168.159.130
Address:        192.168.159.130#53

Name:   web1.com
Address: 192.168.159.130

5.dns從域設置

 vim /etc/named.rfc1912.zones
zone "web1.com" IN {
    type slave;
    file "slaves/web1.com.zone";
    masters { 192.168.159.130;};
};

重啟服務后：

[root@localhost ~]# nslookup 
> web1.com
Server:         192.168.159.131
Address:        192.168.159.131#53

Name:   web1.com
Address: 192.168.159.130

HTTP

1安裝HTTP服務
yum -y install httpd
2.編輯配置文件創建兩個虛擬主機
vim /etc/httpd/conf/httpd.conf

<VirtualHost 192.168.159.130:80>
       ServerAdmin webmaster@dummy-host.example.com
       DocumentRoot /var/www/html/host1/
       ServerName 192.168.159.130
       ErrorLog logs/dummy-host.example.com-error_log
       CustomLog logs/dummy-host.example.com-access_log common

</VirtualHost>
<VirtualHost 192.168.159.129:80>
       ServerAdmin webmaster@dummy-host.example.com
       ServerAdmin webmaster@dummy-host.example.com
       DocumentRoot /var/www/html/host1/
       ServerName 192.168.159.130
       ErrorLog logs/dummy-host.example.com-error_log
       CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>

3.添加一個地址
ip addr add 192.168.159.129 dev ens33
4 編輯主頁文件

[root@localhost conf]# cat /var/www/html/vhost1/index.html 
床前明月光
[root@localhost conf]# cat /var/www/html/host1/index.html 
日照香爐生紫煙

5 訪問成功

6 配置訪問控制
在相應的地方插入以下哦欸之

<Directory "/var/www/html/vhost1">
        options None
        AllowOverRide AuthConfig
        AuthType Basic
        AuthName "wellcome to login .."
        AuthBasicProvider file
        AuthUserFile /etc/httpd/conf/.htpwd
        Require user zhangsan lisi
    </Directory>
         <Directory "/var/www/html/host1">
        options None
        AllowOverRide AuthConfig
        AuthType Basic
        AuthName "wellcome to login .."
        AuthBasicProvider file
        AuthUserFile /etc/httpd/conf/.htpwd
        Require user zhangsan lisi
    </Directory>

創建用戶密碼

  htpasswd -c -m /etc/httpd/conf/.htpwd zhangsan
    htpasswd -m /etc/httpd/conf/.htpwd  lisi
   htpasswd -m /etc/httpd/conf/.htpwd  wangwu
