Question

我试图将django与芹菜一起使用celerybeat运行定期任务。我将ced进程设置为systemd

[Unit]
Description=my celery daemon
After=network.target

[Service]
PIDFile=/var/run/celery/celery.pid
Type=forking
User=myuser
Group=www-data
RuntimeDirectory=celery
RuntimeDirectoryMode=0770
WorkingDirectory=/opt/myapp/
ExecStart=/opt/myapp/.virtualenv/bin/celery multi start worker1 \
    --app=myapp \
    --concurrency=1 \
    --schedule=/var/run/celery/celerybeat-schedule \
    --pidfile=/var/run/celery/celery.pid \
    --logfile=/opt/myapp/log/celery.log \
    --loglevel=INFO \
    --beat
ExecStop=/opt/myapp/.virtualenv/bin/celery multi stopwait worker1 \
    --pidfile=/var/run/celery/celery.pid \
    --logfile=/opt/myapp/log/celery.log \
ExecReload=/opt/myapp/.virtualenv/bin/celery multi restart worker1 \
    --pidfile=/var/run/celery/celery.pid \
    --logfile=/opt/myapp/log/celery.log \

[Install]
WantedBy=multi-user.target

这一切都运行良好..但我注意到它产生3/4进程，尽管只有1个worker，并发设置为1.为什么这个？我的目标是让一名工作人员运行，将任务排队，而不是暂时同步执行。

$ ps aux | grep celery：

Celery守护程序为systemd
