####virtualmachine

flask的app.run()方法运行服务器应用，默认是只能在本机访问的！！！

Externally Visible Server If you run the server you will notice that the server is only accessible from your own computer, not from any other in the network. This is the default because in debugging mode a user of the application can execute arbitrary Python code on your computer.

If you have debug disabled or trust the users on your network, you can make the server publicly available simply by changing the call of the run() method to look like this:

app.run(host='0.0.0.0') This tells your operating system to listen on all public IPs.

####gunicorn pip install gunicorn apt-get install nginx (venv) root@ubuntu-virtual-machine:/var/wb# which nginx /usr/sbin/nginx conf

location / { # First attempt to serve request as file, then # as directory, then fall back to index.html #try_files $uri $uri/ /index.html;

            try_files $uri @gunicorn_proxy;
            # Uncomment to enable naxsi on this location
            # include /etc/nginx/naxsi.rules
    }
    location @gunicorn_proxy {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_redirect off;
            proxy_pass http://127.0.0.1:8000;
    }

###error handle [ERROR] Connection in use: ('localhost', 8000) reason:

run.py unguardedly calls app.run - this actually calls werkzeug.serving.run_simple which starts a sub-process to handle incoming requests ... which you don't want to do when running under gunicorn (since gunicorn will handle the process management for you). solution: modify run.py

#! /usr/bin/
from wb  import app
if __name__ == '__main__':
    app.run(debug=True)
