我的日志文件中有以下内容，相隔几秒钟。我假设有些东西试图找到我的数据库或管理页面或其他东西，但我不确定。

【问题讨论】：

点击是否来自同一个ip？查看该 IP 在日志中是否有任何“200 OK”类型的命中。如果都是 404，他们什么也没找到。如果有 200 个，他们发现了一些东西。

我现在只记录 404 错误。如何在不记录我网站上的每一个 200 OK 点击的情况下记录 200 OK 点击？如果我记录了每一个 ok 的命中，那将是一个庞大的列表需要筛选。

您的网络服务器应该已经在自己的访问日志中记录了命中。

我的服务器的日志文件在哪里？

取决于您的网络服务器和平台。 unix 上的 Apache 往往有 /var/log/httpd 或 /var/log/apache2，但它可以被覆盖并出于多种原因移动到其他地方。您必须查看服务器的配置并自己找出答案。

【参考方案1】：

某些东西（可能是机器人）正在扫描您的网络服务器以查找这些页面，这些页面不存在，因为它们收到 404 错误。扫描很常见——通常是脚本在寻找漏洞。

我们无法判断您的数据库是否已被入侵。虽然您发布的日志内容并不表明您已被入侵，但只是被扫描了。

【讨论】：

不过，看看@Marc B 的关键评论

【参考方案2】：

这是查找站点上是否安装了管理 Web 界面的常见尝试。任何网站不时收到此类尝试都是正常的。

如果这是一个流量日志，则此特定尝试根本不会成功，因为所有请求都会导致 HTTP 404。如果这只是错误消息的报告，您应该查看流量日志以查看是否有任何请求来自该 IP 导致了非 404 响应。

不过，仅仅因为这样的尝试会找到它正在寻找的 Web 界面并不意味着它已被黑客入侵。这仅意味着有人知道您正在使用的 Web 界面，并且可以尝试在其中找到安全漏洞。一般来说，如果系统得到适当的更新和修补，这种风险很小。
