尝试在 14.04 上部署多节点 openstack Juno。这是我的 charm 配置文件：
nova-cloud-controller:
openstack-origin: cloud:trusty-juno
network-manager: "Neutron"
openstack-dashboard:
openstack-origin: cloud:trusty-juno
keystone:
openstack-origin: cloud:trusty-juno
glance:
openstack-origin: cloud:trusty-juno
cinder:
openstack-origin: cloud:trusty-juno
ext1-quantum-gateway:
openstack-origin: cloud:trusty-juno
ext2-quantum-gateway:
openstack-origin: cloud:trusty-juno
nova-compute:
openstack-origin: cloud:trusty-juno
在 Juju gui 上，所有节点和关系线都是绿色的；但是，我无法访问 horizon 下的 Project->Access&Security 页面。查看 rabbitmq 日志文件，似乎所有来自各种服务的访问都被拒绝：

查看 /etc/rabbitmq，我没有看到任何文件！删除和添加关系，每Juju 没有为 openstack 配置 rabbitmq？，并没有解决问题。以下是一些典型的诊断：
rabbitmqctl list_users
Listing users ...
cinder []
glance []
guest [administrator]
nagios-rabbitmq-server-0 []
neutron []
nova []
...done.
# rabbitmqctl list_permissions -p openstack
Listing permissions in vhost "openstack" ...
cinder .* .* .*
glance .* .* .*
neutron .* .* .*
nova .* .* .*
...done.
rabbitmqctl list_vhosts
Listing vhosts ...
/
nagios-rabbitmq-server-0
openstack
...done.
有什么想法吗？
干杯，
编辑 1：似乎 cloud:trusty-juno charms 与 rabbitmq charm 不兼容。对于 cinder 和 nova-cloud-controller，必须设置 notification_driver = rabbit。此外，必须在 rabbitmq 服务器中为 nova、neutron 和 cinder 用户手动设置密码。在所有情况下，都必须手动重启相关服务。（请注意，对于 cinder 和 cloud-controller，juju 会覆盖 notification_driver。）不幸的是，仍然无法访问 Access&security 页面。Keystone 报告了以下内容：
(keystone.common.wsgi): 2014-11-24 23:51:42,238 WARNING Authorization failed. The request you have made requires authentication. from 10.0.0.62
(keystone.common.wsgi): 2014-11-24 23:51:42,251 WARNING Expecting to find username or userId in passwordCredentials - the server could not comply with the request since it is either malformed or otherwise incorrect. The client is assumed to be in error.
10.0.0.62 是 nova-cloud-controller。
编辑 2：（相对于第一个回应。）
# sudo rabbitmqctl cluster_status
Cluster status of node rabbit@rabbitmq1 ...
[{nodes,[{disc,[rabbit@rabbitmq1]}]},
{running_nodes,[rabbit@rabbitmq1]},
{partitions,[]}]
...done.
期待下一个版本。
答案1
支持 Juno OpenStack 版本的 charm 更新与 RabbitMQ charm 完全兼容 - 我们在日常 charm 开发周期中对任何 OpenStack charm 所做的每次提交都进行了测试。
RabbitMQ（rabbitmq-server）charm 应该会自动在 openstack vhost 下为所有相关服务创建用户，并通过关系数据向 cinder、nova、neutron 等提供密码...这一切都直接在 RabbitMQ 的底层状态数据库中完成 - 所以不要指望任何东西会出现在 /etc/rabbitmq 中！
由于某种原因，这个密码似乎与 RabbitMQ 中的密码不对应 - 您正在集群配置中运行，所以我想知道集群是否存在一些问题 - 尝试运行：
sudo rabbitmqctl cluster_status
在其中一个 RabbitMQ 节点上查看是否列出了所有单元；我怀疑 RabbitMQ 集群设置可能存在一些问题，并且您可能在某种裂脑配置中运行，因此远程服务的密码仅在 RabbitMQ 单元的子集中匹配。
我还检查了 cinder 和 nova-cc charms 的通知驱动程序配置；尽管它们使用的是较旧的弃用名称 rpc 驱动程序，但它会重新映射到正确的 oslo.messaging（共享 OpenStack 消息传递库）驱动程序。我们将在下一个开发周期直接使用 oslo.messaging 。
