nginx如何实现端口转发

server {

        listen       80;

 #      listen       [::]:80 default_server;

        server_name  test.com

        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.

        include /etc/nginx/default.d/*.conf;

        location / {

        }

        location /news{

                proxy_pass http:test.com:8081/;

        }

    }

    server {

        listen 8081;

        server_name localhost;

        root /var/www/project;

        location / {

        index index.php index.html index.htm;

        if ( !-e $request_filename){

        rewrite ^(.*)$ /index.php?s=/$1 last;

        break;

                }

        }

       #error_page 500 502 503 504  /50x.html;

       #location = /50x.html {

       #root /usr/share/ngixn/html;

       #}

       #我部署的是PHP项目，这里配置PHP解析

        location ~ \.php$ {

        fastcgi_pass 127.0.0.1:9000;

        fastcgi_index index.php;

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        include /etc/nginx/fastcgi_params;

        include /etc/nginx/fastcgi.conf;

        }
