我目前正在制作一个使用Amazon AMI创建简单EC2实例的云形态模板。创建此实例后，我有一个UserData字段，它将在新实例中运行bash代码以安装Jenkins，Git，Apache Maven等，并更新PATH变量和./bashrc文件。
我成功完成了大部分这些要求，但每当我尝试将任何内容回显到bashrc文件中时，它似乎都无法正常工作。我甚至检查了运行bash代码后生成的EC2实例中的日志文件，它没有错误或任何出错的地方。
以下是我的整个cloudformation代码：

我甚至通常只使用echo命令进行测试，它工作正常。如果我尝试将任何内容回显到bashrc文件中，它就不起作用。任何帮助将不胜感激。
答案 0 :(得分：1)
我尝试过几件事。
首先，您的脚本以root身份运行，因此不需要sudo命令。这不应该影响任何事情，但你应该知道你的脚本在哪个用户下运行。
第二，但与第一个相关，你在/root/.bashrc或/home/ec2-user/.bashrc中寻找变化吗？如果是后者，请指定完整路径。
