无法 运行 Flask 应用程序作为 Centos 7 服务器上 systemd 的服务
Unable to run flask application as a service with systemd on Centos 7 server
我可以在 virtualenv /web_services/flask_api/flask_api 中 运行 flask app 像这样：
gunicorn --workers=4 --bind=localhost:8000 --log-level=error app:app
但是，当我尝试 运行 它作为一项服务时，它不起作用。这是我用来创建 .service 配置文件的 post：
https://blog.miguelgrinberg.com/post/running-a-flask-application-as-a-service-with-systemd
这是我的 web_service.service 文件的样子：
[Unit]
Description=Sample web service
After=network.target
[Service]
User=aaa.bbb
WorkingDirectory=/web_services/flask_api/flask_api
ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error web_service:app
Restart=always
[Install]
WantedBy=multi-user.target
保存此文件后我做了：
$ sudo systemctl daemon-reload
$ sudo systemctl start web_service
$ sudo systemctl enable web_service
systemctl | grep running 未显示此 api。
在检查此服务的状态时，我得到了这个：
sudo systemctl status web_service
● web_service.service - Sample web service
Loaded: loaded (/etc/systemd/system/web_service.service; enabled; vendor preset: disabled)
Active: failed (Result: start-limit) since Mon 2020-06-01 16:15:15 EDT; 13s ago
Process: 1016 ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error web_service:app (code=exited, status=1/FAILURE)
Main PID: 1016 (code=exited, status=1/FAILURE)
不知道我在这里遗漏了什么或做错了什么。任何帮助将不胜感激..
它通过更改解决了：
