AWS: cloud-init失败

Question

我有一个自定义的centos AMI，我在其中安装了来自https://s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-latest.amzn1.noarch.rpm的aws-cfn-bootstrap。

运行cloudformation脚本后，该实例的cloud-init被卡住。我尝试查看cloud-init.log。我不能调试这个问题。我不知道如何调试它。需要帮助，我现在被困在这里了。下面是日志中的一些错误。帮我解决这个问题。

是否需要修改cloud-init.cfg ?？

您的问题是mount命令。是否使用现有服务器启动实例(使用实例的AMI)？您可以通过在该服务器上运行该命令进行检查，并查看它是否正常工作。

我相信你的命令是这样的。

mount -o ro,sync -t iso9660 /dev/xvda /tmp/tmptIJHi2
