当我重新启动服务器并获得与以下语句相同的效果时，如何终止工作程序：
pkill -9 -f 'celery worker'
来自芹菜文件：
如果工人在经过考虑的时间后不会关闭，因为被困在无限循环或类似环境中，你可以使用KILL信号强制终止工人：
但是我作为systemd服务启动并使用以下配置来使用以下systemd单元文件启动它：
[Unit]
Description=Celery Service
After=network.target
[Service]
Type=forking
User=dsangvikar
Group=www-data
EnvironmentFile=-/etc/default/celery
WorkingDirectory=/home/dsangvikar/apps/msbot/
ExecStart=/home/dsangvikar/apps/msbot/msbotenv/bin/celery multi start \
-A microsoftbotframework.runcelery.celery chatbotworker --concurrency=4 \
--workdir=/home/dsangvikar/apps/msbot/ --logfile=/var/log/celery/%n.log
--pidfile=/var/run/celery/%n.pid
ExecStop=/home/dsangvikar/apps/msbot/msbotenv/bin/celery multi stopwait
RuntimeDirectory=celery
[Install]
WantedBy=multi-user.target
当我sudo systemctl status celery时，我获得状态和pid。我用它杀了它。但是工作进程不会退出。我想强行杀死他们。我的程序逻辑在每次重启服务器时重新创建它们。但是，即使在系统重启时它们也没有被杀死，所以各种不同的问题都会出现。

Celery multi不应该用于生产。
这就是我正在使用的：
它启动10个主要流程，每个流程包含2个工作人员。总共有20个工人流程。
[program:celery_worker]
numprocs=10
process_name=%(program_name)s-%(process_num)s
directory=/opt/worker/main
environment=PATH="/opt/worker/main/bin:%(ENV_PATH)s"
command=/opt/worker/main/bin/celery worker -n worker%(process_num)s.%%h --app=python --time-limit=3600 -c 2 -Ofair -l debug --config=celery_config -E
stdout_logfile=/var/log/celery/%(program_name)s-%(process_num)s.log
user=username
autostart=true
autorestart=true
startretries=99999
startsecs=10
stopsignal=TERM
stopasgroup=false
stopwaitsecs=7200
killasgroup=true
如果您正在运行作业，则不希望将TERM信号发送到PoolWorker进程，因为它会导致作业提前中止。你真正想要做的是将TERM信号发送到MainProcess，它将等待作业结束然后关闭。
所以你想要停止主要进程，如果它归结为杀死那么你想要作为一个群体杀死。
使用此命令启动工作线程关闭。如果工作人员未能在超级用户配置中stopwaitsecs时间退出，那么将发送一个终止信号，这将导致killasgroup被设置为真后的所有内容。
sudo supervisorctl stop celery_worker:*
上面的supervisord配置开始的示例。

如果您希望立即停止，请将stopwaitsecs设置为1。
