AH00124：请求超出了 APACHE 服务器上 10 个内部重定向的限制

Question

我在aws 上使用php 7 来运行我的php 应用程序，它有一些不错的流量。但是在一天结束时，我会检查我的 apache 日志中的错误/活动。我每天发现一件常见的事情，有 10 到 15 行相同的错误

AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

但是我无法得到这个错误，为什么会发生，不知何故我知道它是由于重定向/.htaccess 中的一些规则而发生的。我无法找到逻辑故障的位置，因为它不会在 localhost 上出现任何错误，也不会在运行任何脚本时出现错误。

下面是我的 .htaccess 代码

<IfModule mod_rewrite.c>
    RewriteEngine On

    # for subdomain like test.example.com to redirect to https://test.example.com
    #RewriteCond %{HTTP_HOST} !^www\. [NC,OR]

    # We are setting here the default file to load while the URL is called followed by fallback files

    # Adds a trailing directory if rewritten URI is a direcory
    RewriteCond %{DOCUMENT_ROOT}/app/$1 -d
    RewriteRule ^(.*?[^/])$ %{REQUEST_URI}/ [L]

    # Over here we have set the default root directory now request will be directly made from this directory
    RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]

问题是您的重定向规则会导致无限循环。 添加 LimitInternalRecursion 子句只会隐藏问题。

首先你必须确定是什么请求导致了这个问题： 检查您的 apache 访问日志行，返回代码为 500，其时间戳与错误日志中的时间戳相同。

其次，您可以激活重写规则日志记录以进行调试。见：https://httpd.apache.org/docs/2.4/mod/mod_rewrite.html
