nginx在fastcgi模块中转发真实的后端IP

网上流传着一份nginx fastcgi_params,大家在nginx下用fastcgi跑PHP大多用的是这个版本,但是这个版本有2个问题,1是默认的buffersize太小,php一旦输出比较多的error_log就挂了,2是没有转发HTTP_X_FORWARD_FOR和HTTP_CLIENT_IP这两个变量.我的服务器是在lighttpd后面跑的nginx+php,wordpress收不到正确的IP,于是垃圾评论无法正常工作.现在我改了一份更合用的版本,提供出来.

fastcgi_buffers 8 128k; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param HTTP_X_FORWARDED_FOR $http_x_forwarded_for; fastcgi_param HTTP_CLIENT_IP $http_client_ip; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200; fastcgi_buffer_size 256k; #fastcgi_buffers 4 256k; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; #fastcgi_read_timeout 300; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on;
