Question

我一直在尝试与主管per these instructions设置gunicorn。但是当我跑步时

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

我收到错误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

我的日志文件中出现以下错误。

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。

Answer 1

问题的根源似乎是我遇到app.py的问题。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，当我通过flask run --host=0.0.0.0运行服务器时，我没有遇到大错误。

我通过调整位于.conf

的主管/etc/supervisor/conf.d/Server-CardLearning.conf文件来解决这个问题。

新.conf文件显示为：

[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！〜喘气！〜

安装库后，我跑了：

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

现在，如果这还没有解决，我还发现在主管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！

Answer 2

在我的情况下，我不小心删除了主管日志指向的日志文件夹，因此创建这些文件夹并重新启动主管就成功了。

示例 supervisor.conf

[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

所以我所做的就是:-

mkdir /var/log/supervisor/

在那之后：-

sudo supervisorctl status all

主管：ERROR（产生错误）在尝试发射gunicorn时
