编辑Apache的配置文件
<Directory "/var/www/html/admin">
AllowOverride ALL
authuserfile "/etc/httpd/uers"
authname "input your name "
authtype basic
require valid-user //指的是所有用户
# require user admin //这个指的是单个用户
</Directory>
测试时ip+admin（目录）

NameVirtualHost *:443 //写在ssl文件中的其实就是Apache虚拟主机的内容，port由80变为443，只是多了带色的那几行，仅此而已
