[英]Unable to Run Flask on Twisted web server, WSGI application error
[英]Unable to run flask application as a service with systemd on Centos 7 server
我可以像这样在 virtualenv /web_services/flask_api/flask_api
中运行 flask 应用程序:
gunicorn --workers=4 --bind=localhost:8000 --log-level=error app:app
但是,当我尝试将其作为服务运行时,它不起作用。 这是我创建.service
配置文件的帖子:
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
systemctl | grep running
不显示此 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)
不知道我在这里错过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:
ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error web_service:app
至
ExecStart=/web_services/flask_api/flask_api/bin/gunicorn --workers=4 --bind=localhost:8000 --log-level=error app:app
