提问by user61629
I have a Django project on an Ubuntu EC2 node, which I have been using to set up an asynchronous using Celery.
我在 Ubuntu EC2 节点上有一个 Django 项目，我一直在使用它来设置异步，使用Celery.
I am following thisalong with the docs.
我正在关注这个和文档。
I've been able to get a basic task working at the command line, using:
我已经能够在命令行上完成一项基本任务，使用：
(env1)ubuntu@ip-172-31-22-65:~/projects/tp$ celery --app=myproject.celery:app worker --loglevel=INFO
To start a worker. I have since made some changes to the Python, but realized that I need to restart a worker.
开始一个工人。此后我对 Python 进行了一些更改，但意识到我需要重新启动一个工作程序。
From the command line, I've tried:
从命令行，我试过：
ps auxww | grep 'celery worker' | awk '{print }' | xargs kill -9
But I can see that the worker is still running.
但我可以看到工人仍在运行。

(env1)ubuntu@ip-172-31-22-65:~/projects/tp$ sudo ps auxww | grep celeryd | grep -v "grep" | awk '{print }' | sudo xargs kill -HUP
kill: invalid argument H
Usage:
kill [options] <pid> [...]
Options:
<pid> [...] send signal to every <pid> listed
-<signal>, -s, --signal <signal>
specify the <signal> to be sent

-L, --table list all signal names in a nice table

Try this in terminal
在终端试试这个
ps aux|grep 'celery worker'
You will see like this
你会看到这样
username 29042 0.0 0.6 23216 14356 pts/1 S+ 00:18 0:01 /bin/celery worker ...
Then kill process id by
然后杀死进程ID
sudo kill -9 process_id # here 29042
If you have multiple processes, then you have to kill all process id using above killcommmand
如果您有多个进程，则必须使用上述命令kill终止所有进程 ID
sudo kill -9 id1 id2 id3 ...
From the celery doc
来自芹菜文档
ps auxww | grep 'celery worker' | awk '{print }' | xargs kill -9
OR if you are running celeryd
或者如果你正在跑步 celeryd
ps auxww | grep celeryd | awk '{print }' | xargs kill -9
Note
笔记
If you are running celeryin supervisor, even though kill the process, it automatically restarts(if autorestart=Truein supervisor script).
如果你正在运行celery的supervisor，即使杀的过程中，它会自动重新启动（如果autorestart=True在主管脚本）。

celery -A proj control shutdown
Edited, incremeting a litte bit.
编辑，增加一点点。
You should use this command from the root of your project, the "proj" is the name of your project, for instance if your Django project is called DjangoApp the command should look like this
您应该从项目的根目录使用此命令，“proj”是您的项目名称，例如，如果您的 Django 项目名为 DjangoApp，则该命令应如下所示
celery -a DjangApp control shutdown
celery -a DjangApp control shutdown
this should/will stop your celery worker from the project
这应该/将阻止您的芹菜工人参与该项目

ps auxww | grep 'celery worker' | grep -v " grep " | awk '{print }' | xargs kill -9
this one is very similar to one presented before but improved because avoid the error that shows when attempt to kill the grep process..
这个与之前介绍的非常相似，但有所改进，因为避免了在尝试终止 grep 进程时显示的错误..
