Nginx常见配置

应公司需求 最近修改了nginx 配置：

透传客户端IP和端口给后端服务

（PHP）

fastcgi_param X-Real-IP $http_x_forwarded_for;

fastcgi_param X-Real-PORT $remote_port;

（proxy_pass）

proxy_set_header X-Real-IP  $http_x_forwarded_for;

proxy_set_header X-Real-Port $remote_port;

支持跨域：

add_header "Access-Control-Allow-Headers" "Content-Type, *";

add_header "Access-Control-Allow-Origin" "$http_origin";

add_header  "Access-Control-Allow-Credentials" "true";

add_header  "Access-Control-Allow-Methods" "GET, OPTIONS, POST";
