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

这种情况下的AMQP服务器是指RabbitMQ。
简单的答案是量子服务器不能loginrabbitmq。 由于您没有收到“ECONNREFUSED”错误，服务器是可以联系的，这意味着最有可能运行在该IP上的RabbitMQ服务器。
确保你的RabbitMQ密码是正确的。 例如，福尔瑟姆指南说：
rabbitmqctl change_password guest password
…这意味着rabbitmq用户是'guest'，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）
