Apache-2.4

在使用 mod_proxy_fcgi 和 PATH_INFO 時重寫 URL 會出現錯誤 404

  • May 2, 2017

我在 Apache 2.4.25 上有一個虛擬主機，通過 mod_proxy_fcgi 連接 PHP-FPM 7.1.4，如下所示：

<VirtualHost *:80>
   ServerName example.com
   DocumentRoot /srv/www/example.com

   <Directory /srv/www/example.com>
       AllowOverride All
       Require all granted
   </Directory>

   SetEnvIfNoCase ^Authorization$ "(.+)" HTTP_AUTHORIZATION=$1
   <FilesMatch ".+\.ph(p[3457]?|t|tml)$">
       SetHandler "proxy:unix:/run/php/example.sock|fcgi://localhost"
   </FilesMatch>
</VirtualHost>

大多數應用程序都可以完美地使用此設置，但有一個應用程序使用 PATH_INFO 來提取請求。該應用程序的 .htaccess 中有類似的內容：

RewriteEngine On

RewriteCond $1 ^index\.php
RewriteRule ^(.*)$ - [PT,L]

RewriteRule ^(.*)$ index.php/$1 [PT,L]

簡而言之，所有不index.php應該的東西都應該作為路徑傳遞給它。訪問 URL http://example.com/index.php/test[PATH_INFO] => /test按預期工作和顯示，但訪問http://example.com/test

AH01071: Got error 'Primary script unknown\n'

mod_rewrite 和 mod_proxy_fcgi 的設置LogLevel trace6表明重定向正確完成，並且正確的路徑也傳遞給 PHP-FPM。

如何讓 Apache 正確重寫 URL 並同時傳遞 PATH_INFO？

**注意：**這個問題可能與Apache 2.4 + PHP-FPM + ProxyPassMatch類似，但在我的情況下，我已經在使用SetHandler. 問題在於 PATH_INFO 部分，那裡的答案似乎沒有解決。

經過幾天的努力，我已經擷取並檢查了在 Apache 和 PHP-FPM 之間發送的 CGI 標頭，並使用所述組件的不同版本進行了測試。事實證明，不同版本的 Apache 設置SCRIPT_FILENAME變數的方式不同，這在 PHP-FPM 中是無法解釋的。

Apache 2.4.18（我使用的 Ubuntu 16.04 中的預設值）填充變數如下：

SCRIPT_FILENAME proxy:fcgi://localhost/srv/www/index.php

而 Apache 2.4.25 設置：

SCRIPT_FILENAME /srv/www/index.php

mod_proxy_fcgi 的 Apache 文件提到了自 Apache 2.4.26（截至 2017-05-02 尚未發布）以來可用的指令ProxyFCGIBackendType ，預設為“FPM”。描述中有以下註釋：

基於此指令的設置而更改的值的一個範例是 SCRIPT_FILENAME。以前使用 mod_proxy_fcgi 時，SCRIPT_FILENAME 以字元串“proxy:fcgi://”為前綴。這個變數是一些通用 FastCGI 應用程序將其讀取為腳本輸入的變數，但 PHP-FPM 會去除前綴然後記住它正在與 Apache 對話。在 2.4.21 到 2.4.25 中，該前綴被伺服器自動剝離，破壞了 PHP-FPM 在某些場景下檢測和與 Apache 互操作的能力。

似乎我偶然發現了“一些場景”。我自己的問題的答案是：不要使用 Apache 2.4.21 到 2.4.25，因為它們包含錯誤。使用較低版本或等待修復錯誤的更新版本。
