使用 nginx 和 php 找不到文件

Question

我尝试使用 nginx 在同一个域上运行节点 js 和 php。但是 php ("/ajax") 的位置不起作用。我总是收到消息“找不到文件。”。 nginx 日志打印

到目前为止，URL 是 http://localhost:8085/ajax，脚本位于 /var/www/public 文件夹 /ajax 不存在（所有路径都不存在，因为一切都应重定向到 /var/www/public/index.php）

nginx | 2017/08/27 20:47:48 [error] 6#6: *6 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.23.0.1, server: localhost, request: "GET /ajax HTTP/1.1”，上游：“fastcgi://172.23.0.4:9000”，主机：“localhost:8085”

nginx | 172.23.0.1 - - [27/Aug/2017:20:47:48 +0000] "GET /ajax HTTP/1.1" 404 27 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, 像壁虎) Chrome/60.0.3112.113 Safari/537.36" "-"

这是我的配置，我要改什么？

upstream react {
    server react:3000;
    keepalive 8;
}

server {
    listen 0.0.0.0:80;

    server_name  localhost;

    location / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://react;
        proxy_redirect off;
    }

    location /ajax {
        index index.php index.html;
        root /var/www/public;

        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

    client_max_body_size 5m;
}

我试过了

fastcgi_param SCRIPT_FILENAME /var/www/public$fastcgi_script_name;

在某些线程中建议，但这不起作用

当前配置对我有用，但是 /ajax 被传递给 php-fpm。我无法摆脱 REQUEST_URI 等所有变量中的 /ajax 前缀

upstream react {
    server react:3000;
    keepalive 8;
}

server {
    listen 0.0.0.0:80;

    server_name localhost;

    location / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://react;
        proxy_redirect off;
    }

    location /ajax {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME /var/www/public$fastcgi_script_name;
        fastcgi_param QUERY_STRING    $query_string;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }

    client_max_body_size 5m;
}

因此，过去 3 天我一直在努力解决您的问题，以更好、更深入地了解 FASTCGI。我在 NGINX 和 FPM 之间放置了一个记录器，这有助于我更好地理解交互。以下是我认为应该适合您的配置

解决聊天问题后更新配置

upstream react {
    server react:3000;
    keepalive 8;
}

map $fastcgi_script_name $fastcgi_script_name_fcgi {
    "~*/ajax/(?P<rest_url>.*)$"   /$rest_url;
    default $fastcgi_script_name;
}

map $request_uri $request_uri_fcgi {
    "~*/ajax/(?P<rest_url>.*)$"   /$rest_url;
    default $request_uri;
}

map $document_uri $document_uri_fcgi {
    "~*/ajax/(?P<rest_url>.*)$"   /$rest_url;
    default $document_uri_fcgi;
}

server {
    listen 0.0.0.0:80;

    server_name localhost;

    location / {
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://react;
        proxy_redirect off;
    }

    location /ajax {
        alias /var/www/public;
        try_files $uri @php;
    }

    location @php {
        fastcgi_split_path_info ^/ajax/(.+\.php)(/.+)$;
        fastcgi_pass fpm:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param  SCRIPT_NAME        /index.php;
        fastcgi_param  REQUEST_URI        $request_uri_fcgi;
        fastcgi_param  DOCUMENT_URI       $document_uri_fcgi;
        fastcgi_param  SCRIPT_FILENAME    /var/www/public/index.php;
    }

    client_max_body_size 5m;
}

所以基本思想是使用alias 指令从document_root 替换/ajax。然后覆盖 request_uri 和其他参数，以便正确的 url 到达 PHP 代码以进行路由解析。

以下是我调用 http://vm/ajax/router.php?x=2 时我的 php 脚本收到的部分内容

{
  "COOKIES": null,
  "GET": {
    "x": "2"
  },
  "POST": [],
  "REQUEST": {
    "x": "2"
  },
  "HEADERS": null,
  "SERVER": {
    "HOME": "/var/www",
    "SCRIPT_FILENAME": "/var/www/html/router.php",
    "DOCUMENT_ROOT": "/var/www/html",
    "DOCUMENT_URI": "/router.php",
    "REQUEST_URI": "/router.php?x=2",
    "SCRIPT_NAME": "/router.php",
    "CONTENT_LENGTH": "",
    "CONTENT_TYPE": "",
    "REQUEST_METHOD": "GET",
    "QUERY_STRING": "x=2",
    "FCGI_ROLE": "RESPONDER",
    "PHP_SELF": "/router.php",
    "argv": [
      "x=2"
    ],
    "argc": 1
  }
}

如你所见，/ajax
