当我尝试访问example.com/blog和/var/log/nginx/error.log时,我一直收到“找不到文件”错误：

FastCGI sent in stderr: "Primary script unknown" while reading 
response header from upstream

这是我的nginx配置：

upstream example {
  server unix:/home/deployer/example/shared/tmp/sockets/puma.sock fail_timeout=0;
}

server {
  listen 80;
  server_name example.com;

  location @example {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    proxy_pass http://example;
  }

  location /blog {
    root /var/www/example_blog;
    index index.php;

    if (!-e $request_filename) {
      rewrite  ^(.*)$ /blog/index.php?q=$1  last;
    }

    location ~ .php(?|$) {
      include /etc/nginx/fastcgi_params;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    }
  }

  location = /50x.html {
    root html;
  }

  location = /404.html {
    root html;
  }

  location @503 {
    error_page 405 = /system/maintenance.html;
    if (-f $document_root/system/maintenance.html) {
      rewrite ^(.*)$/system/maintenance.html break;
    }
    rewrite ^(.*)$/503.html break;
    }

  if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)$){
    return 405;
  }

  if (-f $document_root/system/maintenance.html) {
    return 503;
  }
}

server {
  server_name www.example.com;
  return 301 $scheme://example.com$request_uri;
}

server {
  listen 80;
  server_name assets.example.com;

  if ($request_method !~ ^(GET|HEAD|PUT|PATCH|POST|DELETE|OPTIONS)$){
    return 405;
  }

  if (-f $document_root/system/maintenance.html) {
    return 503;
  }
}

在/etc/php/7.0/fpm/pool.d/www.conf中：

user = www-data
group = www-data

listen.owner = nginx
listen.group = nginx
;listen.mode = 0660

一直在谷歌搜索和尝试各种方式,但仍然无法让它通过这个错误.

解决方法:

问题是位置/博客{root / var / www / example_blog; …将文件放在/ var / www / example_blog / blog /中.

只有在通过将$document_root与URI连接起来构造文件路径时,root才适用.否则,您需要重写URI或使用别名指令.有关详情,请参见this document.

别名指令可以像这样实现：

location = /blog { rewrite ^ /blog/ last; }

location ^~ /blog/ {
    alias /var/www/example_blog/;
    index index.php;

    if (!-e $request_filename) {
        rewrite  ^(.*)$ /blog/index.php?q=$1  last;
    }

    location ~ \.php${
        if (!-f $request_filename) { return 404; }

        include /etc/nginx/fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    }
}

使用^?修饰符可以避免与同一级别的其他正则表达式位置块存在任何歧义.有关详情,请参阅this document.

为了避免诸如/ blogx之类的URI问题,请在位置和别名上使用尾随/.并添加一个完全匹配的位置来处理/博客.
