#添加Server，转发一个，添加一个，frp服务端和客服端保持一致  
server {
	listen       80;
	server_name  test.xxx.com;

	location / {
		proxy_pass http://127.0.0.1:50000;

	}

	error_page 404 /404.html;
		location = /40x.html {
	}

	error_page 500 502 503 504 /50x.html;
		location = /50x.html {

	proxy_connect_timeout 300s;
	proxy_send_timeout 300s;
	proxy_read_timeout 300s;
	proxy_set_header X-Real-IP $remote_addr;
	proxy_set_header REMOTE-HOST $remote_addr;
	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

2.域名解析

  1. 建立多个二级域名解析，如：aaa.xxx.com,bbb.xxx.com,ccc.xxx.com
  2. 解析到同一个公网主机IP上
  3. 在内网机器上，开三台tomcat(注意端口冲突)，修改tomcat/webapps/ROOT/index.jsp(做标识)，在frp client中配置

3.测试

可以看到，不同的二级域名可以访问内网同一台机器上不同端口提供的服务。
