折腾:

【已解决】Mac本地用Celery实现延时执行任务

期间,去用了代码:

<code># celery_task.py
from celery import Celery

# app = Celery('tasks', broker='redis://localhost//')
app = Celery('tasks', broker='redis://localhost')

@app.task()
def add(x, y):
   return x + y
</code>

保存为celery_task.py

然后去运行,结果出错:

<code>➜  server celery -A celery_task  worker


celery@licrifandeMacBook-Pro.local v4.1.0 (latentcall)

Darwin-17.5.0-x86_64-i386-64bit 2018-05-11 17:34:53

.&gt; app:         tasks:0x103e1bef0

.&gt; task events: OFF (enable -E to monitor tasks in this worker)

[queues]
.&gt; celery           exchange=celery(direct) key=celery

</code>

估计是本地Mac中没有运行redis?

celery Error 61 connecting to localhost:6379. Connection refused

<code>➜  server redis-server

【已解决】Mac中安装和运行redis

然后再回去运行celery试试

就正常,没有错误了:

<code>➜  server celery -A celery_task  worker


celery@licrifandeMacBook-Pro.local v4.1.0 (latentcall)

.&gt; task events: OFF (enable -E to monitor tasks in this worker)

[queues]
.&gt; celery           exchange=celery(direct) key=celery
</code>

【总结】

此处Celery中,broker设置的是redis,运行celery出错:

consumer Cannot connect to redis Error 61

原因是:

redis(服务)没有运行

解决办法:

去安装和运行redis服务即可。
