nginx+uwsgi+flask 服务器部署后无法正常访问

Nginx配置： 

    
   upstream test1 {
		server  unix:/usr/local/python_object/test_1/uwsgi/uwsgi.sock;
        server 0.0.0.0:8888;
    }

    server {
        listen       443 ssl;
        server_name  www.xxx.online;
        ssl_certificate  /usr/local/nginx/conf/1_www.xxx.online_bundle.crt;
        ssl_certificate_key  /usr/local/nginx/conf/2_www.xxx.online.key;
        ssl_session_timeout 5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on; 

        location / {
            include uwsgi_params;
            uwsgi_pass test1;
        }
     }
     server {
         listen 80;
         server_name www.xxx.online;
         return 301 https://$host$request_uri;
		}

项目中uwsgi.ini配置：

[uwsgi]
chdir=/usr/local/python_object/test_1
home=/usr/local/python_object/test_1/test_1_env
module=app
callable=app
master=true
processes=2
chmod-socket=666
logfile-chmod=644
procname-prefix-spaced=zm_test_api_about
py-autoreload=1
http=0.0.0.0:8888

vacuum=true
socket=%(chdir)/uwsgi/uwsgi.sock
stats=%(chdir)/uwsgi/uwsgi.status
pidfile=%(chdir)/uwsgi/uwsgi.pid
daemonize=%(chdir)/uwsgi/uwsgi.log

有什么问题？

搞了半天是443端口未启动导致的问题

验证方法为开发已get请求接口，直接在服务端请求，即可查看到详细报错信息，如：curl: (7) Failed connect to www.xxx.online:443; No route to host
