Another way of writing

Modify the nginx configuration file so that nginx receives the request and forwards it to the uwsgi server

upstream test_server{
	server 10.211.55.2:8000;
}

#gzip  on;
server {
	listen  8000;
	server_name api.baidu.site;

	location/{
		include uwsgi_params;
		uwsgi_pass test_server;
	}

}

server {
	listen       80;
	server_name  www.baidu.site;

	#charset koi8-r;

	#access_log  logs/host.access.log  main;
	location /xadmin {
		include uwsgi_params;
		uwsgi_pass test_server;
 	}

	location /ckeditor {
		include uwsgi_params;
		uwsgi_pass test_server;
	}

	location/{
		root   /home/python/Desktop/front_end_pc;
		index  index.html index.htm;
	}

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