Nginx做反向代理时访问端口被自动去除

使用的Nginx版本 : nginx/1.13.10

出现问题的配置文件如下

upstream http-web {

                server 0.0.0.0:9000;

        }

server {

        listen       8088;

        server_name mysql_web;

        resolver 8.8.8.8;

        location / {

                proxy_pass http://http-web;

                #Proxy Settings

                proxy_redirect     off;

                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_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;

                proxy_max_temp_file_size 0;

                proxy_connect_timeout      300;

                proxy_send_timeout         300;

                proxy_read_timeout         300;

                proxy_buffer_size          4k;

                proxy_buffers              4 32k;

                proxy_busy_buffers_size    64k;

                proxy_temp_file_write_size 64k;

        }

        error_page   500 502 503 504  /50x.html;

        location = /50x.html {

                root   html;

        }

}

测试结果：

[root@nginx-server conf.d]# curl http://172.30.45.10:8088 -v

< HTTP/1.1 302 Found

< Server: nginx/1.13.10

< Date: Wed, 29 May 2019 14:32:10 GMT

< Content-Length: 0

< Connection: keep-alive

< x-frame-options: SAMEORIGIN

< Location: http://172.30.45.10/login #<== 端口被nginx去除

正确的配置文件如下：

upstream http-web {

                server 0.0.0.0:9000;

        }

server {

        listen       8088;

        server_name mysql_web;

        resolver 8.8.8.8;

        location / {

                proxy_pass http://http-web;

                #Proxy Settings

                proxy_redirect     off;

                proxy_set_header   Host             $host:$server_port; #Host头部需要增加端口，否则端口会被Nginx去除

                proxy_set_header   X-Real-IP        $remote_addr;

                proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

                proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;

                proxy_max_temp_file_size 0;

                proxy_connect_timeout      300;

                proxy_send_timeout         300;

                proxy_read_timeout         300;

                proxy_buffer_size          4k;

                proxy_buffers              4 32k;

                proxy_busy_buffers_size    64k;

                proxy_temp_file_write_size 64k;

        }

        error_page   500 502 503 504  /50x.html;

        location = /50x.html {

                root   html;

        }
