折腾：
【未解决】Flask-SocketIO测试出错：POST socket.io EIO 400 BAD REQUEST
期间，把gunicorn从最新版本19.6
pip uninstall gunicorn
Uninstalling gunicorn-19.6.0
pip install gunicorn==18.0
然后去运行之前可以正常运行的supervisorctl但是出错了：
(RunningFast) ➜ staging supervisorctl -c supervisor.conf restart runningfast_staging runningfast_staging: ERROR (not running) runningfast_staging: started |
去看log是：
usage: gunicorn [OPTIONS] [APP_MODULE] gunicorn: error: No application module specified. |
对应的配置是：
(RunningFast) ➜ staging cat supervisor.conf … [program:runningfast_stable] directory=/root/RunningFast/stable command=/root/Envs/RunningFast/bin/gunicorn -w 1 -b 0.0.0.0:21084 run:app & startsecs=0 stopwaitsecs=0 autostart=false autorestart=false stdout_logfile_maxbytes=1MB stderr_logfile_maxbytes=1MB stdout_logfile=/root/RunningFast/stable/logs/gunicorn.log stderr_logfile=/root/RunningFast/stable/logs/gunicorn.err [program:runningfast_staging] directory=/root/RunningFast/staging command=/root/Envs/RunningFast/bin/gunicorn -w 1 -b 0.0.0.0:21085 run:app & startsecs=0 stopwaitsecs=0 autostart=false autorestart=false stdout_logfile_maxbytes=1MB stderr_logfile_maxbytes=1MB stdout_logfile=/root/RunningFast/staging/logs/gunicorn.log stderr_logfile=/root/RunningFast/staging/logs/gunicorn.err |
但是单独运行却可以：

supervisorctl gunicorn: error: No application module specified
【总结】
对于：
之前用最新的19.6的gunicorn，supervisor可以通过配置：
supervisor.conf
中的：
command=/root/Envs/RunningFast/bin/gunicorn -w 1 -b 0.0.0.0:21085 run:app & |
正常运行flask的app：
supervisorctl -c supervisor.conf restart runningfast_staging |
但是换成旧版本18.0的gunicorn后，却无法正常用supervisord去运行flask的app了。
只能通过手动去运行：
gunicorn -w 1 -b 0.0.0.0:21085 run:app &
具体原因，未知，暂时也无法解决。
