セキュリティが強化されたようで、config.json に user を追加しています。
一旦動いてしまえば、Unit 最高。

Flask

$ cd
$ mkdir project1 && cd project1
$ python3 -m venv venv
$ source venv/bin/activate
V pip install Flask
V nano main.py

main.py

from flask import Flask
application = Flask(__name__)
@application.route("/")
def index():
    return "Hello Project1!"
if __name__ == "__main__":
    application.run()

V deactivate

Unit - Ubunt22.04

$ cd
$ sudo -i
# curl --output /usr/share/keyrings/nginx-keyring.gpg https://unit.nginx.org/keys/nginx-keyring.gpg
# nano /etc/apt/sources.list.d/unit.list

/etc/apt/sources.list.d/unit.list

# apt update
# apt install unit unit-dev unit-python3.10
# systemctl restart unit

Unit 設定

# nano config.json

config.json

{
    "listeners": {
        "*:80": {
            "pass": "applications/flask_app"
        }
    },
    "applications": {
        "flask_app": {
            "type": "python",
            "user": "<user>",
            "path": "/home/<user>/project1",
            "home": "/home/<user>/project1/venv",
            "module": "main"
        }
    }
}

# curl -X PUT --data-binary @config.json --unix-socket /var/run/control.unit.sock http://localhost/config
# service unit restart

以上です。
