php - 找不到文件 nginx php-fpm

Question

我已经仔细查看了这里的每个问题，并尝试应用规定的修复程序但没有成功。

我正在使用 wordpress:4.7.3-php7.0-fpm-alpine docker 图像，前面有一个单独的 nginx 容器。

当我 curl wordpress 时，我得到:

File not found.

当我检查 wordpress 容器日志时，我得到:

127.0.0.1 -  16/Mar/2017:06:26:24 +0000 "GET /index.php" 404
127.0.0.1 -  16/Mar/2017:06:31:27 +0000 "GET /index.php" 404
127.0.0.1 -  16/Mar/2017:06:32:16 +0000 "GET /index.php" 404
127.0.0.1 -  16/Mar/2017:06:37:17 +0000 "GET /index.php" 404
127.0.0.1 -  16/Mar/2017:06:39:09 +0000 "GET /index.php" 404

实际的nginx错误是:

2017/03/16 06:26:24 [error] 17#17: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 10.128.0.7, server: k8wp, request
: "GET / HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000"

我正在使用 php 7

/var/www/html # php-fpm -v
PHP 7.0.16 (fpm-fcgi) (built: Mar  3 2017 23:07:56)
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
    with Zend OPcache v7.0.16, Copyright (c) 1999-2017, by Zend Technologies

我的nginx配置是

server {
    root /app;

    # Add index.php to the list if you are using PHP
    index index.php index.html index.htm index.nginx-debian.html;

    server_name _localhost;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass    127.0.0.1:9000;
            fastcgi_index   index.php;
            fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include         fastcgi_params;
    }
}

我正在以用户 www-data 的身份运行 nginx:

user www-data;

根据 /usr/local/etc/php-fpm.d/www.conf 用户和组取消注释并设置为 www-data

Answer 1

该错误表明您的 SCRIPT_FILENAME 不正确。您的评论:

in the wordpress container it's at /var/www/html/index.php in the nginx container it's at /app

表明 nginx 和 php-fpm 正在查看不同的文档根目录。

在这种情况下，使用:

fastcgi_param   SCRIPT_FILENAME  /var/www/html$fastcgi_script_name;
