Python 如何在supervisord的同一文件中发出杀死gunicorn和运行gunicorn的命令？

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：

sudo fuser -k 5000/tcp

停止所有gunicorn进程，然后执行以下命令：

gunicorn /home/ubuntu/dev/nxchill/nxchill:app -b localhost:5000

sudo supervisorctl reread
sudo service supervisor restart
sudo service supervisor restart

因此，当我在conf文件中执行

命令

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：

gunicorn /home/ubuntu/dev/nxchill/nxchill:app -b localhost:5000

sudo supervisorctl reread
sudo service supervisor restart
sudo service supervisor restart

nxchill致命性退出过快（进程 日志（可能有详细信息）

记录如下：

Traceback (most recent call last):

    worker.init_process()

    return self.load_wsgiapp()

    return util.import_app(self.app_uri)

    __import__(module)

现在，即使只有一个命令存在，也会出现相同的错误。

解决方案是忽略命令

sudo fuser-k 5000/tcp

，直接运行

gunicorn

命令

该命令应启动服务器，以便flask应用程序在系统重新启动时永远不会关闭，等等

尽管如此，由于没有执行杀死端口的命令，将使用越来越多的端口。这可以由cron作业每天或每周运行一次。不必担心此命令会杀死flask应用程序，因为它将由supervisord恢复
