nginx:FastCGI 在 stderr 中发送:“主要脚本未知”

nginx:FastCGI 在 stderr 中发送:“主要脚本未知”

在 64 位 arch linux 上使用最新版本的 nginx(1.10.0)和 php-fpm(PHP 7.0.6)。

当尝试请求 index.php 以进行 DokuWiki 安装时,我收到以下错误:

2016/05/21 22:09:50 [error] 11099#11099: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.70.3, server: doku.test.com, request: "GET /install.php HTTP/1.1", upstream: "fastcgi://unix:/run/php-fpm/php-fpm.sock:", host: "doku.test.com"

以下是相关的服务器配置:

server {
  listen 80;
  server_name doku.test.com;
  root /var/www/doku/public_html/;
  access_log /var/log/nginx/scripts.log scripts;

  location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass  unix:/run/php-fpm/php-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }

}

这是 fastcgi_params:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  REQUEST_SCHEME     $scheme;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;

从我的服务器配置中可以看出,我试图记录SCRIPT_FILENAME参数的输出,因为我的所有研究似乎都指向这是罪魁祸首。以下是 nginx.conf 的相关部分:

log_format scripts '$document_root$fastcgi_script_name > $request';

当请求index.php页面时,会生成以下内容scripts.log

/var/www/doku/public_html/index.php > GET /index.php HTTP/1.1

对该文件执行 ls:

-rwxr-xr-x 1 nginx nginx 182 May 21 06:45 /var/www/doku/public_html/index.php

值得注意的是,nginx 守护程序和 php-fpm 守护程序都配置为使用 nginx 组以 nginx 用户身份运行。我不知道为什么我会收到初始错误,因为日志记录有效地证明它SCRIPT_FILENAME确实指向正确的路径。

在我查看过的所有 ServerFault 答案中,将该参数添加到服务器配置似乎是解决我的错误的最佳方法,但在我看来它似乎并不能解决问题。

有什么建议么?

首先检查您是否在www.conf文件中为 PHP-FPM (FastCGI 进程管理器) 设置了正确的监听地址。因此,打开www.conf文件 (location: /etc/php5/fpm/pool.d/www.conf),它应该会看到类似以下内容:

Start a new pool named 'www'.
[www]

;prefix = /path/to/pools/$pool

user = www-data
group = www-data

listen = 127.0.0.1:8080

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions. 
; Default Values: user and group are set as the running user
;                 mode is set to 0660
listen.owner = www-data
listen.group = www-data
listen.mode = 0660

在监听地址下,检查是否设置了环回地址(它标识您的服务器)和端口号。然后在文件中nginx.conf更改fastcgi_pass127.0.0.1:8080,因此最终它应该看起来像:

server {
  listen 80;
  server_name doku.test.com;
  root /var/www/doku/public_html/;
  access_log /var/log/nginx/scripts.log scripts;

  location ~ \.php$ {
    include fastcgi_params;
    fastcgi_pass  127.0.0.1:8080;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  }

}

注意我在示例中使用了端口 8080,您可能需要更改它。
