Nginx 错误日志：[错误] open()“/etc/nginx/html/status/”失败（2：没有此文件或目录），客户端：127.0.0.1，服务器：127.0.0.1

Question

我正在运行基于 Ubuntu 的 LEMP 服务器，其中 Nginx 的 google pagespeed、fastcgi 和 modsecurity 模块处于活动状态。我正在查看我的 Nginx 错误日志，但无法弄清楚这些错误的含义、原因以及如何修复它们。似乎有什么东西在无效目录中寻找文件，但我不知道为什么。如果有人能看看我的 Nginx 日志/var/log/nginx/error.log，并告诉我发生了什么、为什么以及如何解决它，我将不胜感激！如果您有任何想法，请告诉我！
