AWS：cloud-init失败

Question

我有一个自定义的centos AMI，我从https://s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-latest.amzn1.noarch.rpm安装了aws-cfn-bootstrap。

运行cloudformation脚本后，该实例的cloud-init卡住了。 我试图查看cloud-init.log。 我无法调试该问题。 而且我不知道如何调试它。 需要帮助，我目前被困在这里。 以下是日志中的一些错误。 帮助我解决这个问题。

我需要更改cloud-init.cfg吗？

您的问题是mount命令。 您是使用现有服务器（使用AMI）启动实例吗？ 您可以通过在该服务器上运行该命令来检查该命令是否正常运行。

我相信您的命令就是这样。

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