适用于 Windows 更新的 Centos Squid 代理服务器

我正在运行 Centos 7 作为我的操作系统，并安装了 squid 来为我的公司缓存 Windows 更新。

查看日志文件，显示所有内容都是 tcp_miss，包括访问 Windows 更新服务器时。

我希望我的 squid 安装仅缓存 Windows 更新。有人知道发生了什么以及为什么它不缓存 Windows 更新吗？

以下是 access.log 文件的摘录：

根据您配置文件中已有的内容，我猜您已经找到了有关 Windows 更新的 Squid 常见问题解答： http://wiki.squid-cache.org/SquidFaq/WindowsUpdate

我建议指定以下缓存选项以确保可以缓存更大的对象。最大对象大小需要足够大才能容纳最大的更新文件。32GB 应该可以容纳最大的服务包，或者您可能想要缓存的任何 ISO 文件。

cache_mem 512 MB
minimum_object_size 0
maximum_object_size 32768 MB
maximum_object_size_in_memory 16384 KB
range_offset_limit 32768 MB windowsupdate
quick_abort_min -1

如果这没有帮助，您可能还需要研究 refresh_pattern 行的以下附加选项（除了 reload-into-ims）：

  • 忽略无缓存
  • 忽略无存储
  • 忽略私人
  • 覆盖到期
  • 覆盖 lastmod
  • 忽略重新加载

例如，我使用这样的一行来缓存所有 doc 或 pdf 文件：

refresh_pattern -i \.(doc|pdf)$ 4320 80% 86400 ignore-no-cache ignore-no-store ignore-private override-expire override-lastmod reload-into-ims ignore-reload

答案2

恐怕只要客户端使用 https 访问 Windows 更新服务，就无法缓存它。Squid 仅充当隧道因此无法检查您在请求什么，因此无法缓存它。

您可以在鱿鱼维基

更新：

对于缓存更新，你可以看看微软，但它适用于安装在 Windows 平台上。
