OpenStack Quantum Log 显示 AMQP 服务器：5672 无法访问：套接字已关闭

在 OpenStack Folsom 安装中，我的量子服务器日志在 /var/log/quantum/server.log 显示：

什么原因可能导致这个错误？

答案1

本例中的 AMQP 服务器指的是 RabbitMQ。

答案很简单，量子服务器无法登录到rabbitmq。因为你不是收到“ECONNREFUSED”错误，服务器可以联系，这意味着很可能有一个 RabbitMQ 服务器正在该 IP 上运行。

确保您的 RabbitMQ 密码正确。例如 Folsom 指南说：

rabbitmqctl change_password guest password

...这意味着 rabbitmq 用户是‘guest’并且 rabbitmq 密码是‘password’。

这必须匹配 /etc/quantum/quantum.conf 中列出的用户名和密码

# IP address of the RabbitMQ installation
rabbit_host = 10.0.0.1
# Password of the RabbitMQ server
rabbit_password = password
# Port where RabbitMQ server is running/listening
# rabbit_port = 5672
# User ID used for RabbitMQ connections
# rabbit_userid = guest

（注释掉的行是默认的）
