Use Virtualenv, Uwsgi, nginx to Deployment flask

This article describes how to use Virtualenv, Uwsgi, nginx to flask the steps of the deployment.

Upgrade Packages

Execute the following command to ensure that your machine has the latest packages installed.

sudo apt-get update
sudo apt-get upgrade

Installing Python and Virtualenv

sudo apt-get install build-essential python-dev python-pip
sudo pip install virtualenv

Create a directory to store your Web site

For example, create a MySite directory under the/home/gzlihao/webservice directory

mkdir MySite

Configuring Virtualenv and installing Flask, UWSGI

Virtualenv. env
source. env/bin/activate
Pip Install flask
Pip Install Uwsgi

Create hello.py under the MySite directory

The contents of hello.py are as follows:

fromimport Flaskapp = Flask(__name__)@app.route("/")def hello():    return"Hello World!"if"__main__":    app.run(host=‘0.0.0.0‘, port=8080)

Note that the app.run needs to be placed under and the if __name__ == "__main__" host needs to be set to 0.0.0.0so that UWSGI does not execute it.

Configure Uwsgi

Add the configuration file Uwsgi.ini, which reads as follows:

[Uwsgi]chdir=/home/gzlihao/webservice/mysite home=/home/gzlihao/webservice/mysite/.env module=Hello callable=app master=true processes=2 socket=% (chdir)/mysite.sock chmod-socket=666 logfile-chmod=644 daemonize=% (chdir)/uwsgi.log uid=Gzlihao gid=Gzlihao procname-prefix-spaced=MySite 

Start Uwsgi

Uwsgi–ini Uwsgi.ini

You can see the following files added under the MySite directory
mysite.sockAnduwsgi.log

Installing Nginx

Deactivate
sudo apt-get install Nginx

Configure Nginx

Create the mysite.conf file under the/etc/nginx/sites-availabel directory, as follows:

server {    80;    server_name www.mysite.com;    charset utf-8;    5M;    location / {         include uwsgi_params;         uwsgi_pass unix:/home/gzlihao/webservice/mysite/mysite.sock;     }     location /static {         alias /home/gzlihao/webservice/mysite/static;     }}

In order to use this configuration file to take effect, create a mysite.conf link file:

Cd/etc/nginx/sites-enabled
Ln-s. /sites-available/mysite.conf mysite.conf

Nginx Restart

Syntax checking of nginx configuration prior to reboot

Nginx-t

Then a smooth restart of the Nginx

Kill-hup 27198

Where 27198 is the Nginx master process number, you can use the ps -efl | grep nginx | grep master get

Visit website

Edit C:\Windows\System32\drivers\etc\hosts the file to add a
[Deployment MySite's IP address] www.mysite.com
For example
192.168.229.166 www.mysite.com

Open the browser, input www.mysite.com , enter, you can see the output results.
