以 phpMyAdmin 网站为例
将 phpMyAdmin 隐藏在认证代理后面，这样用户在向 phpMyAdmin 提供 MySQL 凭证之前就需要进行认证

官方文档
AuthBasicProvider Directive

步骤

1. 使用 htpasswd 创建密码文件

   htpasswd -c /usr/share/phpmyadmin/passwd test01

    New password: Re-type new password: Adding password for user test01
   

   cat /usr/share/phpmyadmin/passwd

    test01:$apr1$SUzFEIsh$ZYz1pDpxTuaqxORN8oYem0
   

   如果需要修改密码，先使用 htpasswd -D 删除，再使用 htpasswd -b修改

   htpasswd -D /usr/share/phpmyadmin/passwd test01

    Deleting password for user test01
   

   htpasswd -b /usr/share/phpmyadmin/passwd test01 123456

    Adding password for user test01
   

2. 配置需要代理的网站

   cd /etc/httpd/conf.d
   cat phpmyadmin.conf

   ## Possible values for the Options directive are "None", "All",# or any combination of:#   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews## Note that "MultiViews" must be named *explicitly* --- "Options All"# doesn't give it to you.## The Options directive is both complicated and important.
