Python 意外的_帧-类60应为内容标头，但得到的是非内容标头帧

我要做的是，假设您有几个需要执行的工作流。这些工作流具有任务，任务的目标是不同的主机。 实现这一点的最快方法是运行流程中的每个工作流，并并行运行它们

我正在尝试运行python多处理来执行一个远程函数，我在芹菜的帮助下调用该函数。如果我只运行一个进程，我的程序运行正常。但是当我运行多个进程时，我会得到下面的错误。就我所知，问题在于在同一频道上同时发布。线程/etc之间不应共享通道

我怎么做芹菜来解决这个问题？是我应该用'celeryd'命令启动的参数，还是我需要在python程序中启动它

芹菜3.1.11版（Cipater）

amq—0.9.1版

使用芹菜时，不需要使用python多处理模块。芹菜为你照顾一切

在名为tasks.py的文件中定义任务

from celery import Celery
app = Celery('tasks', broker='amqp://guest@localhost//')

@app.task
def add(x, y):
    return x + y

现在假设

add

函数实际上是您希望并行运行的函数。让我们也考虑一下条款。并行意味着同时，而异步意味着不同步。我不能保证任务将同时运行，尽管我可以保证它们不会同步运行。因此，让我们继续使用术语async

芹菜有一组用于异步流控制的原语。您感兴趣的两个是

组

和

和弦

group

允许您运行一组异步任务，并对所有异步任务的结果执行ask block（完成加入时的尝试）

chord

提供了与

group

相同的功能，但在所有任务完成时会触发回调

调用代码的示例：

WAIT_TIME = 10 # how ever long you are willing to wait for your tasks

from tasks import add
from celery import group

future = group(add.s(i**i, i**i) for i in xrange(10))()
results = future.get(timeout=WAIT_TIME)

---

芹菜任务自动在其自己的进程（您产生的工作者）中运行，不需要您自己创建进一步的进程

任何代码都会有帮助。这个问题是因为我在同一个通道上从不同的进程发布。通道是共享的，rabbitmq可能接收交错消息。我不知道如何在同一个通道上同步请求。一个问题是通道不是线程安全的。当您使用共享频道发布消息时，您的帧将按顺序发送，这就是为什么您会出现错误的基本原因我在哪里可以找到我的案例的示例？我在芹菜def test_hello_proc（）：procs=[]中为集群中的q使用此调用：proc=multiprocessing.Process（target=test_hello_aux，args=（q，））proc.start（）procs.append（proc）for procs:proc.join（）
