caddy部署flask服务

1.安装gunicorn

目前Caddy尚不支持uwsgi协议，因此需要安装Gunicorn来连接caddy和flask

pip install gunicorn

2.编写flask服务

xxxxxxxxxx
mkdir test
vim test/test.py

​x
from flask import Flask
app = Flask(__name__)
​
@app.route("/")
def hello():
    return "<h1 style='color:blue'>Hello There!</h1>"
​
if __name__ == "__main__":
    app.run()

3.创建WSGI入口

xxxxxxxxxx
vim test/wsgi.py

xxxxxxxxxx
from test import app
​
if __name__ == "__main__":
    app.run()

4.开启WSGI

xxxxxxxxxx
cd test
gunicorn -b "127.0.0.1:8000" wsgi:app

5.配置caddyfile

xxxxxxxxxx
vim /etc/caddy/Caddyfile

xxxxxxxxxx
test.wofost.com {
    root /data/www/wofost.com/test
    proxy / localhost:8000 {
        transparent
    }
}

xxxxxxxxxx
systemctl restart caddy.service

6.停止或重启flask

xxxxxxxxxx
yum install psmisc
pstree -ap|grep gunicorn
kill -HUP **** #restart
kill -9 **** #shutdown
