r'''看服务器上装 WordPress 缺什么。

== 背景 ==

用户想把 xxmxxs.top 拿来做 WordPress（原来是 Cloudflare Workers 占着）。
WordPress 要 PHP + 数据库，而服务器上现在只跑着 nginx（给遥控中转用）。

== 为什么写成文件 ==

这个查询里有一堆 `$(...)`、`$b`、`2>/dev/null`。
用 `python -c "..."` 传的话，**PowerShell 会先在本机把它们求值**
（报"无法将 systemctl 项识别为 cmdlet"、"未能找到路径 C:\dev\null"）。
这个坑今天踩了太多次 —— 凡是超过两行的远端命令，一律写成文件。
