向您的 MAAS 部署魅力现在您已准备好进行最激动人心的部分:向您的 MAAS 部署魅力!
juju deploy mysql MAAS 现在将为 Juju 分配一个节点,然后 Juju 将 MySQL charm 部署到该节点。同样,在安装 Ubuntu 并部署 charm 时需要几分钟才能完成。
让我们快速检查一下状态:
符咒状态一旦符咒被部署,你就会看到它反映在环境的状态中。
如果您有另一个空闲节点,您可以部署 WordPress 并将其连接到我们刚刚部署的 MySQL 服务:
juju 部署 wordpress juju 添加关系 wordpress mysql juju 公开 wordpress juju 状态
从: https://wiki.ubuntu.com/ServerTeam/MAAS/Juju
我得到了这个:

我试了几次,问题还是一样。aget-state 说机器没有启动,但实际上已经启动了。
我做错了什么?
此外,当我运行 juju debug-log 时,我得到:

成功了!我再次安装 ubuntu 服务器,这次一切顺利,但有一件事。现在当我使用 juju status 时,我看到了以下内容:

公共地址似乎很奇怪,因为它是我的节点的名称。我检查了节点的路由器地址,其中有 wordpress,并在 webbrowser 上输入,但我得到了
502 错误网关 nginx/1.1.19
我不知道该怎么办。请帮帮我。
