Question

我有一个从Marketplace购买的Wowza实例，大约4小时前我能够连接它并正在对它进行一些操作。但是现在当我尝试连接时，会出现Permission denied（publickey）错误。我使用chmod命令给.77提供777权限。这是我认为的真正原因。

从this solution开始，当我尝试将此实例的根卷附加到同一类型的其他实例时，它会给出相同的错误，但是当voulme被分离时，它已成功连接。市场实例的数量只能附加到类似类型的实例上。

现在我如何更改该.ssh目录的权限？你能帮帮我吗？

以下是我尝试连接实例时的日志：

Answer 1

从AWS Marketplace推出的产品有限制，非市场实例主要不是为了强制执行许可。你遇到了其中一个限制。

以下是可能有用的AWS论坛上的相关thread，尤其是帖子中的最后帖子：

如果卷具有AWS Marketplace产品代码：


该卷只能附加到已停止的实例。

您必须订阅该卷上的AWS Marketplace代码。

实例的配置（实例类型，操作系统）必须支持该特定的AWS Marketplace代码。例如，你   无法从Windows实例获取卷并将其附加到Linux   实例

AWS Marketplace产品代码将从卷复制到实例。

我没有检查，但你可以尝试这个技巧。

您可以指定用户数据以在启动期间配置实例或运行配置脚本。 http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html#user-data-shell-scripts

创建新实例时

从Market Place选择AMI
选择实例类型
配置实例 - ＆gt;高级详细信息 - ＆gt;使用过的数据。

在这里添加bash脚本以更改权限。
添加存储空间

更改根设备或从您的EBS快照添加新设备。
标记实例
配置安全组
审核并启动
