Ansible 无法在 Redhat 中为 GRUB 引导加载程序设置密码

Question

As Salam-o-Alikum， 我已经编写了一个 Ansible 剧本，用于在 RedHat 和 Ubuntu 上设置 GRUB 引导加载程序密码，没有错误，我可以在两个位置看到Grub2.cfg的变化。 奇怪的是，当我重新启动两台机器时，Ubuntu 机器要求输入用户名和密码，但 Redhat 机器没有。 我已经看到50 +教程过程是相同的，它非常简单，但我不知道为什么它表现得那样。任何帮助将不胜感激。

这是我尝试过的。

grub-redhat.j2 有一些拼写错误。

第 11 行：set supperusers="{{ grub_user }}"

更改为：set superusers="{{ grub_user }}"

第 12 行：password_pbkdf2 {{ grub_user }} {{ grub_password_v2_passwd }}

更改为：password_pbkdf2 {{ grub_user }} {{ grub_password_v2_passwd }}

如果你打算在多台机器上使用相同的 grub 密码，你可能需要考虑使用 ansible-vault encrypt_string来加密原始密码，然后创建一个额外的任务，该任务运行 grub2-mkpasswd-pbkdf2(grub2-tools-minimal 的一部分(与命令模块并传递给它 vaulted 变量。注册该任务的输出(例如，注册为 grub_password_v2_passwd(将导致运行 playbook 的每个目标都反对接收唯一哈希，即使基础密码相同也是如此。期望模块非常适合此：

expect:
command: grub2-mkpasswd-pbkdf2
responses:
Enter password: '{{ vaulted_raw_password }}'
Reenter password: '{{ vaulted_raw_password }}'
no_log: true
