nginx 代理到 apache - 未记录远程 IP

nginx 代理到 apache - 未记录远程 IP

我使用 nginx 终止网站并使用 PHP-FPM 将其代理到 Apache。我尝试在 apache 日志中记录客户端 IP，但似乎无法使其正常工作。

nginx 配置

server {
  listen         80;
  server_name    www.website.com;

  location ^~ /.well-known/acme-challenge/ {
      alias /var/www/dehydrated/;
  }

  location / {
      return         301 https://$server_name$request_uri;
  }
}

server {
  listen 443 ssl http2;
  server_name www.website.com;

  location / {
      proxy_pass http://1.2.3.4:80;
      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;
      proxy_read_timeout 600;
      proxy_buffer_size   128k;
      proxy_buffers   4 256k;
      proxy_busy_buffers_size   256k;

  ssl_prefer_server_ciphers on;
  ssl_dhparam /etc/nginx/ssl/dhparams.pem;
}

Apache 配置

  <VirtualHost *:80>

    ServerName www.website.com
    ServerAlias origin.www.website.com

    ServerAdmin [email protected]

    DocumentRoot /var/www/www.website.com/trunk

    <IfModule mpm_itk_module>
          AssignUserId www_arenz www_arenz
    </IfModule>
    CustomLog /var/www/www.website.com/apachelogs/www.website.com-access.log combined
    ErrorLog /var/www/www.website.com/apachelogs/www.website.com-error.log

      <FilesMatch "\.php$">
          CGIPassAuth on
          SetHandler "proxy:fcgi://127.0.0.1:9115/
      </FilesMatch>

      RemoteIPHeader X-Real-IP
      RemoteIPTrustedProxy 2.3.4.5/32


  </VirtualHost>

Apache 日志始终显示 2.3.4.5 作为客户端的 IP 地址，这是 nginx 的公网 IP 地址

您可以尝试这个解决方案：

当存在 RemoteIPHeader X-Forwarded-For 时，Apache 不会记录 remoteIP

# Log format config
LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" common
SetEnvIf X-Forwarded-For "^.*\..*\..*\..*" forwarded
CustomLog "logs/access_log" common env=forwarded

# Header config
RemoteIPHeader X-Real-IP
RemoteIPHeader X-Client-IP
RemoteIPInternalProxy 192.168.10.10 192.168.10.11

此外，日志结合使用%h。设置%a，它告诉Apache记录客户端IP为mod_remoteip（%a）而不是主机名（%h）记录的

供你参考：

希望这可以帮到你

您也可以使用 rpaf apache 模块代替 RemoteIP 指令，在 httpd.conf 中设置它

  <IfModule rpaf_module>                                                                                                                                                                                                                                                 
      RPAF_Enable On                                                                                                                                                                                                                                                     
      RPAF_SetHostName On                                                                                                                                                                                                                                                
      RPAF_ProxyIPs 2.3.4.5                                                                                                                                                                                                                                        
      RPAF_Header X-Forwarded-For                                                                                                                                                                                                                                        
  </IfModule>

然后只需添加一个新的日志格式，像这样

LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" forwarded

CustomLog "/var/log/httpd-access.log" forwarded

使用 nginx 作为代理 + apache + php-fpm 效果很好
