尝试通过 juju-gui 进行简单的配置，即 Mysql 和 Wordpress 组合；但是，当我按下部署按钮时，我收到以下通知：
Error deploying mysql
Could not deploy the requested service. Server responded with: cannot download charm "cs:precise/mysql-44": Cannot access the charm store. Are you connected to the internet? Error details: Get https://store.juju.ubuntu.com/charm-info?charms=cs%3Aprecise%2Fmysql-44: dial tcp 91.189.95.66:443: connection timed out
在 /var/log/juju/all-machines.log 下观察到类似的消息：
machine-0: 2014-05-22 17:19:19 DEBUG juju.state.apiserver apiserver.go:127 -> [A] user-admin 2m7.308014762s {"RequestId":25,"Error":"cannot download charm \"cs:precise/mysql-44\": Cannot access the charm store.

以下是我从 ping 得到的信息
ubuntu@node2:/var/log/juju$ ping 91.189.95.67:443
ping: unknown host 91.189.95.67:443
ubuntu@node2:
MAAS 服务器有 2 个网卡，一个面向公众，另一个用于 maas 通信。目标节点有一个连接到 maas 网络的网卡。（旁注 - 我尝试在目标节点上使用 2 个网卡进行实验，一个用于外部，一个用于 maas，方法是定义新的 gw 和路由表。虽然目标节点能够看到外部世界；但是，它与 maas 服务器的通信完全混乱了。所以放弃了。）
以下是目标节点的网络设置：
