配置步骤

安装flask和uwsgi

pip install Flask uwsgi

创建一个简单的flask应用（app.py）或者是自己的flask项目

from flask import Flask
app = Flask(__name__)
 
@app.route('/')
def hello_world():
    return 'Hello, World!'

配置uwsgi，这里我给出自己的配置

[uwsgi]
socket = :5000
wsgi-file = /root/blog/start.py
master = true
callable = app
chdir = /root/blog/
module = start:app
harakiri = 30
vacuum = true
die-on-term = true
limit-as = 512
buffer-size=65535

• socket应该是和nginx通信的socket，注意不是http，因为uwsgi和nginx通信使用的是uwsgi协议
• wsgi-file是程序启动文件，也就是python xxx.py的那个文件，注意写绝对路径
• calllable是程序启动文件中应用的名字，一般就是app（xxx.run()那个xxx）
• chdir是项目的根目录，建议写绝对路径
• module的start是程序启动文件不带.py，app就是上面callable那个app
• 其余参数不用修改

启动uwsgi

uwsgi --ini uwsgi.ini

 配置Nginx (/etc/nginx/sites-available/default)

server {
    listen 80;
    server_name your_domain.com;
 
    location / {
        include uwsgi_params;
        uwsgi_pass the_uwsgi_socket:port;
    }
}

需要修改的是your_domain.com是域名，the_uwsgi_socket就写0.0.0.0，port和uwsgi配置中socket端口保持一致，我这里就是5000

启动nginx

sudo systemctl start nginx

安装Cerbot

sudo apt-get install certbot python3-certbot-nginx

使用certbot为nginx配置https

sudo certbot --nginx

问题及解决

• The -s/--socket option is missing and stdin is not a socket.

• unable to load configuration from uwsgi
