AWS EC2 用户数据未正确解码

AWS EC2 用户数据未正确解码

Rab*_*820 0 bash amazon-ec2 amazon-web-services user-data

我正在尝试创建一个 EC2 实例来托管 Perforce 服务器。我的实例配置了以下用户数据：

\n\n

#!/bin/bash\n\n# Add a newline to the ec2-user prompt string\necho PS1=\\"\\\\n\\$PS1\\" >> /home/ec2-user/.bashrc\n\n# Update all packages\nyum update \xe2\x80\x93y\n\n# Install Perforce packages\n# The RHEL/7 part of the baseurl should be replaced with\n# the latest RHEL version that both Amazon and Perforce support\nrpm \xe2\x80\x93import https://package.perforce.com/perforce.pubkey\ncd /etc/yum.repos.d/\necho [perforce] > perforce.repo\necho name=Perforce >> perforce.repo\necho baseurl=http://package.perforce.com/yum/rhel/7/x86_64 >> perforce.repo\necho enabled=1 >> perforce.repo\necho gpgcheck=1 >> perforce.repo\nyum install \xe2\x80\x93y helix-p4d\n\n# Make directories for the server, owned by new \xe2\x80\x9cperforce\xe2\x80\x9d user\ncd /opt/perforce/servers/\nmkdir danware\ncd danware\nmkdir danware-db danware-chkpts journal\nchown \xe2\x80\x93R perforce:perforce danware\n

我已经测试了上述每个命令，并且知道它们按此顺序手动执行时可以工作。然而，亚马逊的 base64 编码/解码系统的某些方面似乎出现了障碍。启动（并通过所有系统检查）后，当我从 EC2 控制台转到“操作 > 实例设置 > 查看/更改用户数据”时，我看到以下用户数据。请注意几乎每个连字符“-”都被一些奇怪的“a”字符替换。

但是，我不确定这就是问题所在，因为 /var/log/cloud-init-output.log 处的日志文件提供了以下输出（我用 [...] 替换了一些重复文本以保存空间）。请注意这行内容：Failed running /var/lib/cloud/instance/scripts/part-001我已验证此part-001 文件实际上确实具有正确显示的连字符。

更烦人的是，我认为No Match for argument: \xe2\x80\x93y日志文件中的早期行指的是yum update -y我的用户数据中的行。果然，只需从 EC2文档页面运行示例用户数据脚本（该脚本也使用yum update -y），就会给我同样的错误/警告！亚马逊自己的示例脚本不起作用！？那么谁能回答为什么 A) AWS 没有正确显示用户数据代码，以及 B) 为什么我的用户数据会产生上面显示的错误？非常感谢您的帮助！
