我有一个使用nginx + uwsgi + flask的网站。我使用主管来控制uwsgi。使用uwsgi uwsgi_config.ini时效果很好
但是当使用主管时，它总会发出致命的错误，退出得太快。但是，uwsgi进程仍然在后台运行。这意味着我的网站仍在运行。
主管日志是这样的：

这是主管的配置文件：

对于uwsgi，配置如下：
[uwsgi]

有人可以帮忙吗？
uWsgi进程已在端口上运行，您需要在尝试重新运行之前将其停止。
# If you have create uwsgi service
sudo service uwsgi stop
# If you are using emperor
sudo service emperor stop
# If nothing else works, then forcibly kill it
pkill -9 wsgi
从uwsgi config.ini中删除一个配置后，问题就不再出现了问题，这是qazxsw poi
要使用日志记录，请尝试daemonize = /home/www/logs/uwsgi.log
