Exited too quickly (process log may have details)-配置問題

在配置supervisor的時候，提示Exited too quickly (process log may have details)，這個時候一臉懵逼，啥回事，執行太快了？？？

而後仔細看了program塊的配置，發現因爲本身是在測試，運行的命令是sleep 1,而startsecs設置爲3，supervisor認爲程序執行太快致使出錯，把命令改爲sleep 4就能夠了

[program:demo]
command=sleep 1
directory=/
autostart=true
startsecs=3
autorestart=true
startretries=3
; user=root
priority=999
redirect_stderr=true
stdout_logfile_maxbytes=20MB
stdout_logfile_backups = 20
stdout_logfile=/tmp/supervisord/demo.log
stopasgroup=false
killasgroup=false
