我在其中一个服务器的子域“pma”中有一个 phpMyAdmin 副本，位于其中一个名为“app”的目录中（手动从 zip 存档安装，而不是通过 yum 安装），我将其用于数据库相关管理，几个月来运行良好。几天前，当我尝试登录时，我的本地 IP 被阻止，经过大量挖掘后，我在 /var/log/apache2/error_log 中找到以下日志（出于显而易见的原因，我用 <PLACEHOLDER_TEXT> 替换了我的本地 IP 和服务器域）

虽然我熟悉 SSH 和 CLI，但我不是核心服务器管理员，我花了一些时间，并得到了 ISP 和托管服务提供商的帮助，才弄清楚 CSF/LFD 中的 IP 禁止问题，但我正在努力了解实际问题，以便将来可以避免。有人能解释原因吗？谢谢！

我认为我已经找到了该问题的解决方案。我正在寻找的包含详细信息的“日志”文件位于以下文件中：
/var/log/apache2/modsec_audit
