1.先在/www下创建一个net.haha的文件，然后在net.haha下的vim编辑index.html写入想写的内容

[root@rhcsa redhat]# cat /www/net.haha/index.html
this is 192.168.127.11 server

2.继续在/etc/nginx/conf.d/baidu.conf下编辑web配置

[root@rhcsa redhat]# cat /etc/nginx/conf.d/haha.conf
server {listen 192.168.127.11:80;server_name www.haha.com;root /www/net.haha;location / {}

注意：需要手动配置一下192.168.127.11的IP地址

3.使用vim在/etc/named.conf下编辑dnf配置

4.然后vim在/var/named/named.haha.com下编辑www.haha.com 

[root@rhca redhat]# cat /var/named/named.haha.com
$TTL 1D
haha.com. IN SOA haha.com. admin.haha.com. (1 1D 1H 1W 3H)
