实验需求

所有的防火墙全部关闭
分配对应的ip地址
dhcp的服务端因为不要给别人分配ip所以需要自己手动配置

实验

[root@localhost ~]# yum install -y httpd          #下载httpd服务
[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    #网页内容

[root@localhost ~]# yum install -y dhcp       #下载dhcp服务
[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

开启服务

[root@localhost ~]# systemctl restart network
[root@localhost ~]# systemctl start dhcpd

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

[root@localhost ~]# cd /var/named
[root@localhost named]# cp -p named.localhost test.come.zone          #复制模板到配置文件  
[root@localhost named]# vim test.com.zone
