主管:ERROR(产生错误)在尝试发射gunicorn时

Question

根据这些指示,我一直在尝试与主管一起设置gunicorn .但是,当我跑

sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start Server-CardLearning

我收到了错误Server-CardLearning: ERROR (spawn error).

我的配置文件很简单.

[program:Server-CardLearning]
command = gunicorn app:app -b localhost:8000
directory = /home/alexg/www/<flask project>
user = www-data

我在日志文件中收到以下错误.

我哪里错了？我已经尝试了一些我在堆栈溢出时看到的东西,但没有证明与此问题相关.

问题的根源似乎是我遇到了问题app.py.我使用的是我在本地计算机上安装的Flask库而不是服务器,出于某种原因,当我运行服务器时,我没有遇到大错误flask run --host=0.0.0.0.

我通过调整.conf位于的supervisor 文件来解决这个问题/etc/supervisor/conf.d/Server-CardLearning.conf

新.conf文件如下:

[program:Server-CardLearning]
environment=SECRET_KEY="some_secret_key"
command=gunicorn app:app -b localhost:8000
directory=/home/alexg/www/Server-CardLearning
user=alexg
autostart=true
stderr_logfile=/var/log/supervisor/test.err.log
stdout_logfile=/var/log/supervisor/test.out.log

通过添加我能够运行的两个日志文件:

cat /var/log/supervisor/test.err.log

看到我有一个卸载的库!〜哇!〜

安装库后,我运行:

sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start Server-CardLearning

现在,如果这不能解决问题,我还发现在管理控制台中挖掘是有帮助的:

$ sudo supervisorctl
supervisor> help
supervisor> status

我希望这可以帮助别人!
