DHCP和DNS混合配置实验

• 实验准备
• 虚拟机设置HTTPD、DHCP
• 虚拟机配置DNS
• ensp中的设置

实验准备

一台linux系统做服务器，设置其网卡适配器为Net模式VMnet8，一台win10系统为仅主机模式VMnet1，并将防火墙都关闭

[root@localhost ~]# systemctl stop firewalld.service 
[root@localhost ~]# setenforce 0

win10配置：

VMnet1和VMnet8配置

实验要求：server服务器开启以下服务: dhcp、 dns、httpd要求win客户机以访问www. test. com的网站首页，首页内容hello, worldpc2可以获得dhcp分配的地址

虚拟机设置HTTPD、DHCP

[root@localhost ~]# yum install -y httpd
[root@localhost ~]# systemctl start httpd.service 
[root@localhost ~]# netstat -antp | grep httpd
tcp6       0      0 :::80                   :::*        LISTEN     20809/httpd 
[root@localhost html]# systemctl start httpd
[root@localhost html]# netstat -antp | grep httpd
tcp6       0      0 :::80                   :::*                    LISTEN      78410/httpd  
[root@localhost html]# vim /var/www/html/index.html    //设置网页内容

[root@localhost ~]# yum install -y dhcp
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens33      //由于linux要作为dhcp服务器，就需要给它指定一个IP地址，它自己不能dhcp动态获取IP地址

[root@localhost ~]# cp -p /usr/share/doc/dhcp*/dhcpd.conf.example /etc/dhcp/dhcpd.conf
cp：是否覆盖"/etc/dhcp/dhcpd.conf"？ y
[root@localhost ~]# vim /etc/dhcp/dhcpd.conf

[root@localhost ~]# systemctl restart network
[root@localhost ~]# systemctl start dhcpd
[root@localhost ~]# netstat -anup | grep dhcpd
udp        0      0 0.0.0.0:67              0.0.0.0:*                           77041/dhcpd  

虚拟机配置DNS

[root@localhost ~]# yum install -y bind
[root@localhost ~]# vim /etc/named.conf     //设置dns主配置文件

[root@localhost ~]# vim /etc/named.rfc1912.zones    //添加域名并保存

[root@localhost ~]# cd /var/named
[root@localhost named]# cp -p named.localhost test.come.zone
[root@localhost named]# vim test.com.zone

ensp中的设置
