目前，对于Flask项目，每次重新启动时，都很麻烦，需要：
手动去kill掉对应的进程，且要等一段时间：
等之前的4个workker都退出了：

才能重启Flask：
gunicorn -w 4 -b 0.0.0.0:21084 run:app & |
现在希望：
把之前看到的，好像叫做supervisor的，用于任务管理的东西加进来：
可以使得每次重新启动Flask不再这么麻烦，只需要运行一个命令就好，比如restart之类的。

【已解决】安装了supervisor后找不到/etc/supervisord.conf和supervisor
然后自己去使用配置去折腾，结果运行没反应的感觉：
【已解决】supervisor调用gunicorn去运行Flask的app没反应
然后此处即可通过：
[program:runningfast] directory=/root/RunningFast command=/root/Envs/RunningFast/bin/gunicorn -w 4 -b 0.0.0.0:21084 run:app & startsecs=0 stopwaitsecs=0 autostart=false autorestart=false stdout_logfile=/root/RunningFast/logs/gunicorn.log stderr_logfile=/root/RunningFast/logs/gunicorn.err |
的配置，以及：
1.去启动supervisord：
supervisord -c supervisor.conf |
2.（在配置文件改动的情况下）重新加载
supervisorctl -c supervisor.conf reload |
3.去启动和停止自己的Flask的app：
supervisorctl -c supervisor.conf start runningfast supervisorctl -c supervisor.conf stop runningfast supervisorctl -c supervisor.conf restart runningfast |
之后每次即可运行上述两个命令去启动和停止即可。
另外：
<code>supervisorctl -c supervisor.conf status </code>
可以查看状态。
