我有一个conf文件:
[program:nxchill]
directory=/home/ubuntu/dev/nxchill
command=gunicorn /home/ubuntu/dev/nxchill/nxchill:app -b localhost:5000
autostart=true
autorestart=true
stderr_logfile=/var/log/nxchill/nxchill.err.log
stdout_logfile=/var/log/nxchill/nxchill.out.log
我的目标是首先运行命令:
^{pr2}$这将停止所有gunicorn进程,然后停止以下命令:
gunicorn /home/ubuntu/dev/nxchill/nxchill:app -b localhost:5000
因此,当我在conf文件中设置command
部分时:
command=sudo fuser -k 5000/tcp gunicorn /home/ubuntu/dev/nxchill/nxchill:app -b localhost:5000
运行以下命令:
sudo supervisorctl reread
sudo service supervisor restart
sudo service supervisor restart
nxchill FATAL Exited too quickly (process log may have details)
日志包括:

现在,即使只有一个命令存在,也会出现同样的错误。在
解决方案是忽略命令
sudo fuser -k 5000/tcp
,直接运行gunicorn
命令。在命令应该启动服务器,这样flask应用程序就不会在系统重新启动时关闭,等等
但是,越来越多的端口将被使用,因为没有执行杀死它们的命令。这可以由cron作业运行一天或一周一次。不用担心这个命令会杀死烧瓶应用程序,因为它会被主管恢复。在
