EC2 Bootstrap 脚本未在 Ubuntu 上执行

Question

我正在尝试使用以下 CLI 命令为 EC2 Ubuntu 机器设置 bootstrap 脚本：

#cloud-boothook
#!/bin/bash
sudo chmod 750 -R  /home/

以上文本是通过 AWS 控制台在用户数据中设置的。

机器启动后运行，更改模式仍未被上述用户数据脚本修改。

尝试了替代命令：

Content-Type: text/cloud-boothook
Content-Type: text/x-shellscript
sudo chmod 750 -R  /home/

仍然没有更改目录权限。

我的 objective 是在机器启动时使用 750 更改模式设置用户主目录。

如果有任何解决方案，我将不胜感激。

这是为我显示的错误消息：

Answer 1

您正在递归地向 /home 分配 750 权限。

750 表示：

所有者可以读取、写入和执行。
组可以读取和执行。（但不写）
世界可能不会对这个文件做任何事情。

/home 目录本身属于 root，并且在 root 组中。因此，递归应用750后，只有root可以访问/home的内容（包括其他用户的主目录）。

所以，你真的不想那样做。
