我正在尝试为 dnf 设置本地存储库缓存。这个想法是让网络上的一台机器下载一个包，然后网络上任何其他尝试获取该包的机器都会从缓存中接收它。我为此使用了 squid，目前 dnf 通过 squid 服务器请求包，但 squid 每次都记录未命中。我不确定是什么原因造成的，所以我将复制典型的 access.log 消息和 squid.conf 的相关部分。

这是配置：

acl all src 0.0.0.0/0 ::/0

我还注意到，当我设置好 Web 浏览器并通过 squid 进行定向时，有些内容会被缓存。一旦我设置了仅 dnf，就不会再缓存任何内容。
答案1
搞定了。cache_peer 行包含“proxy-only”，这会阻止 squid 缓存来自该对等点的任何内容。删除“proxy-only”一词可完全解决该问题。我想我是从网上某个教程中学到的，该教程肯定尝试了与我不同的东西。
