在多节点 openstack 环境中部署了单节点 swift，即包含 swift-proxy 和 swift-storage charms。这是我的配置文件：
swift-proxy:
zone-assignment: 'manual'
replicas: 1
swift-hash: 'fdfef9d4-8b06-11e2-8ac0-531c923c8fae'
swift-storage:
zone: 1
block-device: /etc/swift/storage.img|10G
（由于这是一个实验性设置，我不需要多个副本）。在循环设备上安装 storage.img 后：
/etc/swift/storage.img /srv/node/loop0 xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0
并重新启动swift服务，我能够上传和下载文件，按照http://docs.openstack.org/icehouse/install-guide/install/apt/content/verify-object-storage-installation.html。
目前，问题是从 Horizon 访问 Swift 时，会返回 [HTTP/1.1 500 INTERNAL SERVER ERROR 49ms] 错误，并在 /horizon/project/containers/ 页面上显示“Something went error!”。Horizon 节点上的 apache 服务器日志和 Swift 节点上的 syslog 未传达任何有用的消息：

需要注意的是，为了使 swift cli 正常工作，我必须使用“--insecure”选项，否则 ssl 验证会失败，例如发出 swift --debug -v -V 2.0 list：
...
DEBUG:iso8601.iso8601:Got u'00' for 'hour' with default None
DEBUG:iso8601.iso8601:Got u'01' for 'minute' with default None
DEBUG:iso8601.iso8601:Got u'35' for 'second' with default None

[Errno 1] _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
其中 10.0.0.59 是 Swift 节点的地址；但是，使用“--insecure”选项：

返回了当前列表。我不确定这两者是否相关，但似乎合理。
非常感谢任何帮助。
