php – Docker Swarm在Nginx中获得真正的IP(客户端主机)

我有一个使用nginx和PHP的堆栈在Docker Swarm Cluster上运行.

在我的PHP应用程序中,我需要获取remote_addr($_SERVER [‘REMOTE_ADDR’]),其中包含访问我的webapp的客户端主机的真实IP.

但问题是IP通过docker swarm集群通知了nginx.它显示了内部IP,如10.255.0.2,但真正的IP是来自客户端主机的外部IP(如192.168.101.151).

我怎么解决这个问题?

我的docker-compose文件:

version: '3'

services:
  php:
    image: php:5.6
    volumes:
      - /var/www/:/var/www/
      - ./data/log/php:/var/log/php5
    networks:
      - backend
    deploy:
      replicas: 1
  web:
    image: nginx:latest
    ports:
      - "80:80"
    volumes:
      - /var/www/:/var/www/
      - ./data/log/nginx:/var/log/nginx
    networks:
      - backend
networks:
  backend:

我的default.conf(vhost.conf)文件:

server {
    listen          80;
    root            /var/www;
    index           index.html index.htm index.php;

    access_log  /var/log/nginx/access.log  main;
    error_log   /var/log/nginx/error.log error;

    location / {
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header        X-Forwarded-Proto $scheme;

        try_files   $uri $uri/ /index.php;
    }

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

    # set expiration of assets to MAX for caching
    location ~* \.(js|css|gif|png|jp?g|pdf|xml|oga|ogg|m4a|ogv|mp4|m4v|webm|svg|svgz|eot|ttf|otf|woff|ico|webp|appcache|manifest|htc|crx|oex|xpi|safariextz|vcf)(\?[0-9]+)?${
            expires max;
            log_not_found off;
    }

    location ~ \.php${
        try_files                   $uri =404;
        fastcgi_index               index.php;
        fastcgi_split_path_info     ^(.+\.php)(/.+)$;
        fastcgi_pass                php:9000;
        include                     fastcgi_params;
        fastcgi_param               SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param               PATH_INFO       $fastcgi_path_info;
        fastcgi_read_timeout        300;
    }
}

我的nginx配置文件:

user  nginx;
worker_processes    3;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    keepalive_timeout   15;
    client_body_buffer_size     100K;
    client_header_buffer_size   1k;
    client_max_body_size        8m;
    large_client_header_buffers 2 1k;

    gzip             on;
    gzip_comp_level  2;
    gzip_min_length  1000;
    gzip_proxied     expired no-cache no-store private auth;
    gzip_types       text/plain application/x-javascript text/xml text/css application/xml;

    log_format  main  '$remote_addr - $remote_user [$time_local]  "$request_filename" "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    include /etc/nginx/conf.d/*.conf;
}
最佳答案
您无法通过覆盖网络获得此功能.如果是you scroll up from bottom on this long-running GitHub issue,您会看到一些选项,可以在Swarm中使用桥接网络与代理服务器来解决此问题.
