ruby-on-rails - Puma shoes 所有请求都来自 127.0.0.1 在 nginx 之后

Question

我遇到一个问题，我的 Rails 日志中显示的唯一 IP 地址是 127.0.0.1，远程 IP 似乎没有通过代理。我不确定我错过了什么。 Nginx 是在综合包中自定义编译的。我也有下面的构建脚本。如果有人能给我一些见解，我将不胜感激。

Nginx 构建方法:

name "nginx"
default_version "1.9.10"

dependency "pcre"
dependency "openssl"

source url: "http://nginx.org/download/nginx-#{version}.tar.gz",
       md5: "64cc970988356a5e0fc4fcd1ab84fe57"

relative_path "nginx-#{version}"

build do
  command ["./configure",
           "--prefix=#{install_dir}/embedded",
           "--with-http_ssl_module",
           "--with-http_stub_status_module",
           "--with-http_gzip_static_module",
           "--with-http_v2_module",
           "--with-http_realip_module",
           "--with-ipv6",
           "--with-debug",
           "--with-ld-opt=-L#{install_dir}/embedded/lib",
           "--with-cc-opt=\"-L#{install_dir}/embedded/lib -I#{install_dir}/embedded/include\""].join(" ")
  command "make -j #{workers}", :env => {"LD_RUN_PATH" => "#{install_dir}/embedded/lib"}
  command "make install"
end

Nginx 配置:

user smart-mobile smart-mobile;
worker_processes 1;
error_log stderr;
pid nginx.pid;
daemon off;

events {
  worker_connections 10240;
}

http {
  #log_format combined '$remote_addr - $remote_user [$time_local] '
  #                    '"$request" $status $body_bytes_sent '
  #                    '"$http_referer" "$http_user_agent"';
  #
  sendfile on;
  tcp_nopush on;
  tcp_nodelay on;
  keepalive_timeout 65;

  gzip on;
  gzip_http_version 1.0;
  gzip_comp_level 2;
  gzip_proxied any;
  gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript application/json;

  proxy_cache_path proxy_cache keys_zone=smart-mobile:10m max_size=1g levels=1:2;
  proxy_cache smart-mobile;

  include /opt/smart-mobile/embedded/conf/mime.types;

  include /var/opt/smart-mobile/nginx/conf/smart-mobile.conf;
}

Nginx 站点配置:

upstream smart_mobile {
  server unix:/var/opt/smart-mobile/puma/puma.socket;
}



  server {
    listen 80;
    server_name 10.10.20.108;

    access_log /var/log/smart-mobile/nginx/smart-mobile-http.access.log;
    error_log /var/log/smart-mobile/nginx/smart-mobile-http.error.log;

    root /opt/smart-mobile/embedded/smart-mobile-rails/public;
    index index.html;

    ## Real IP Module Config
    ## http://nginx.org/en/docs/http/ngx_http_realip_module.html

    location / {
      if (-f /opt/smart-mobile/embedded/smart-mobile-rails/tmp/maintenance.enable) {
        return 503;
      }

      proxy_http_version 1.1;
      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_redirect off;
      try_files $uri $uri/index.html $uri.html @ruby;
    }

    location @ruby {
      proxy_pass http://smart_mobile;
    }

    error_page 404 /404.html;
    error_page 402 /402.html;
    error_page 500 /500.html;
    error_page 502 /502.html;
    error_page 503 @maintenance;

    location @maintenance {
      if ($uri !~ ^/icos/) {
        rewrite ^(.*)$ /503.html break;
      }
    }
  }

彪马配置:

directory '/opt/smart-mobile/embedded/smart-mobile-rails'
threads 2,4
bind 'unix:///var/opt/smart-mobile/puma/puma.socket'
pidfile '/var/opt/smart-mobile/puma/puma.pid'
preload_app!

on_worker_boot do
  ActiveSupport.on_load(:active_record) do
    ActiveRecord::Base.establish_connection
  end
end

before_fork do
  ActiveRecord::Base.connection_pool.disconnect!
end

这对我有用(puma 3.4.0):

# Serve static content if a corresponding file exists.
location / {
  try_files $uri @proxy;

  # NOTE: Parameters below apply ONLY for static files that match.

  expires max;
  add_header Cache-Control "public";
  add_header By-Nginx "yes";     # DEBUG
}

# Serve dynamic content from the backend.
location @proxy {
  proxy_pass http://backend_for_www.site.com;

  proxy_pass_request_headers on;
  proxy_set_header Host $host;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

经过一些探索，我发现:

• Puma 受过专门查看 HTTP header X-Forwarded-For 的训练。 一旦正确通过，Puma 应该将其连接起来。 无需在 Puma 端进行配置。
• request.headers["REMOTE_ADDR"] 将保持 "127.0.0.1"，无论您如何努力，这都不会改变。
• 传递 header X-Real-IP 不会无论如何影响日志记录问题。 基本上，您可以在 Puma 配置文件中使用 set_remote_address header: "X-Real-IP" 从此 header 设置“连接的远程地址”。 但 Puma 本身并没有朝那个方向看，我不知道有任何其他软件会这样做。此处记录:http://www.rubydoc.info/gems/puma/3.2.0/Puma%2FDSL%3Aset_remote_address .
