我无法使用芹菜和WSL打开插座。

请参阅以下信息：

[]输出celery -A proj report：

重现步骤

我在WSL：

须藤apt-get install Rabbitmq-server
sudo服务rabbitmq服务器重启
chmod -R 777 ./ ##否则我没有权限

其他资讯

task.py：

from celery import Celery

# app = Celery('tasks', broker='amqp://jm-user1:sample@localhost/jm-vhost')
# app = Celery('tasks', broker='amqp://guest@localhost//')
app = Celery('tasks', broker='pyamqp://guest@localhost//')

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

如何打开插座以进行通讯？

塞尔吉·扎哈奇琴科（Serge Zaharchenko）

检查rabbitmq是否已启动并正在运行。启用管理控制台：

sudo rabbitmq-plugins enable rabbitmq_management

然后http://localhost:15672使用访客/访客作为凭证访问。查找概述页面>端口和上下文。

如果AMQP绑定到IPv6（：:)，则可能是问题所在。打开rabbitmq服务器配置：

sudo vi /etc/rabbitmq/rabbitmq-env.conf

并注释掉

# By default RabbitMQ will bind to all interfaces, on IPv4 and IPv6 if
# available. Set this if you only want to bind to one network interface or#
# address family.
NODE_IP_ADDRESS=127.0.0.1

然后重新启动服务：
