FATAL & BACKOFF

Exited too quickly (process log may have details) 反复执行会复现，执行太快

2024-08-04 16:39:32,933 WARN exited: spug-api (exit status 0; not expected)
2024-08-04 16:39:32,948 WARN exited: spug-ws (exit status 0; not expected)

脚本有判断exit 0

[ “$num” -eq 0 ] || { echo “runing….” && exit 0 ;}

exec gunicorn -b 127.0.0.1:8000 -w 2 –threads 8 –access-logfile - spug.wsgi

修改为

num=$(ps -ef | grep “/opt/tools/spug-3.0/spug_api/venv/bin/python3.9 /opt/tools/spug-3.0/spug_api/venv/bin/gunicorn” | grep -v grep | wc -l)
[ “$num” -eq 0 ] && {
echo “start runing….”
exec gunicorn -b 127.0.0.1:8000 -w 2 –threads 8 –access-logfile - spug.wsgi
}

supervisor 停止时，gunicorn运行状态

pids=$( ps -ef | grep “/opt/tools/spug-3.0/spug_api/venv/bin/python3.9 /opt/tools/spug-3.0/spug_api/venv/bin/gunicorn” | grep -v grep | awk ‘{print $2}’ | tr ‘\n’ ‘ ‘ )

[ -z “$pids” ] || { echo “runing …$pids” && kill -9 $pids ;}

exec gunicorn -b 127.0.0.1:8000 -w 2 –threads 8 –access-logfile - spug.wsgi
