Nginx反向代理实现多个域名绑定一个服务器多个端口（windows）

背景：项目需要一个服务器上部署多个应用。导致不同的应用需要使用不同的端口。如一些使用80，一些使用81或8080端口。如果域名指向后，仍然需要带端口访问。某个平台对带端口的地址不友好，如微信公众号无法跟带端口域名进行后台绑定。

需求：现有两个项目博客和监控分别80、8080的端口。暂时假设用www.focrs.com指向IP

博客的地址：www.fcors.com

监控地址：www.fcors.com:8080

如何把www.fcors.com:8080换成monitor.fcors.com？

则需要Nginx反向代理。

1、下载Nginx

Nginx官网 http://nginx.org/en/download.html ，本教程以：
nginx/Windows-1.18.0为例子

下载后解压缩

解压缩后打开D:\nginx\conf\nginx.conf

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;
   
    server {
        listen       80;
###########修改此处 server_name###########
        server_name  monitor.fcors.com;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
           ###########修改此处 proxy_pass(代理转发)###########
	    proxy_pass http://127.0.0.1:8999; 
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.htmls
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

2、域名DNS解析（此处教程忽略）

3、启用Nginx

PS扩展。最好把Nginx做成windows服务，设置自动启动

windows利用winsw将Nginx配置到服务中

本教程以 2.11为演示https://github.com/winsw/winsw/releases/tag/v2.11.0

下载后，把文件更新为：nginx_service.exe。

创建文件nginx-service.exe.config和 nginx_service.xml

<configuration>
  <startup>
    <supportedRuntime version="v2.0.50727" />
    <supportedRuntime version="v4.0" />
  </startup>
  <runtime>
    <generatePublisherEvidence enabled="false"/> 
  </runtime>
</configuration>

nginx-service.exe.config

<service>
  <id>nginx</id>
  <name>Nginx Service</name>
  <description>High Performance Nginx Service</description>
  <logpath>D:\nginx\servicelogs</logpath>
  <log mode="roll-by-size">
    <sizeThreshold>10240</sizeThreshold>
    <keepFiles>8</keepFiles>
  </log>
  <executable>D:\nginx\nginx.exe</executable>
  <startarguments>-p D:\nginx</startarguments>
  <stopexecutable>D:\nginx\nginx.exe</stopexecutable>
  <stoparguments>-p D:\nginx\nginx.exe -s stop</stoparguments>
</service>

安装服务
