我有一台在 Windows 10 主机上运行 Debian 9.7.0 64 位的 VM。此 VM 通过 安装了软件包openssh-server、ufw、mysql-server、mysql-client、adminer及其依赖项apt。
Mysql 和 Apache 似乎都正常运行 - 我可以通过 LAN 连接到 mysql 服务器，并且当通过端口 80 访问服务器时会出现 apache2 默认网页。但是，尝试使用/adminer或/adminer.phpURL 访问 adminer 会出现 404 未找到错误：
The requested URL /adminer was not found on this server.
研究这个问题让我看到了这篇文章：https://askubuntu.com/questions/813282/how-to-configure-adminer-to-be-reachable-on-the-local-network
但是，建议的修复对我来说是不可能的 -/etc/adminer目录是空的。没有配置文件可供编辑、符号链接或以其他方式使用：
sierradmin@mysqldev:~$ ls -al /etc/adminer
total 8
drwxr-xr-x 2 root root 4096 Mar 20 2018 .
drwxr-xr-x 79 root root 4096 Jan 27 13:59 ..
sierradmin@mysqldev:~$
我可以采取什么步骤来修复管理员并使其通过局域网运行？
我尝试重新安装 adminer 和 apache、重新安装整个服务器以及先安装 apache2，然后分步骤安装 adminer，但均未成功。
EDIT1：这是运行的结果dpkg --listfiles adminer。这里似乎没有列出任何配置文件。
sierradmin@mysqldev:~$ dpkg --listfiles adminer
