CentOS GRUB 设置密码

随着服务器安全性的日益重要,为GRUB设置密码已成为许多系统管理员的首要任务，GRUB（GRand Unified Bootloader）是Linux系统中的引导加载器，它负责在系统启动时加载操作系统，本文将详细介绍如何在CentOS系统中为GRUB设置密码，以确保系统的安全性。

准备工作

在为GRUB设置密码之前,请确保您具备以下条件：

1. 已安装CentOS系统。
2. 您是root用户或具有root权限的用户。
3. 已安装grub2软件包。

为GRUB设置密码

查找GRUB配置文件

我们需要找到GRUB的配置文件,在CentOS系统中，该文件通常位于/etc/grub2/grub.cfg。

cat /etc/grub2/grub.cfg

编辑GRUB配置文件

使用文本编辑器打开GRUB配置文件：

vi /etc/grub2/grub.cfg

添加密码设置

在GRUB配置文件中,找到GRUB_CMDLINE_LINUX行，并在该行末尾添加grub.pbkdf2_password=YOUR_PASSWORD，其中YOUR_PASSWORD是您要设置的密码。

GRUB_CMDLINE_LINUX="grub.pbkdf2_password=SHA512$5c4f9c8f$5e6b9e8f910101112131415161718191a1b1c1d1e1f202122232425262728292a2b2c2d2e2f3a3b3c3d3e3f404142434445464748494a4b4c4d4e4f505152535455565758595a5b5c5d5e5f606162636465666768696a6b6c6d6e6f707172737475767778797a7b7c7d7e7f808182838485868788898a8b8c8d8e8f909192939495969798999a9b9c9d9e9fA0A1A2A3A4A5A6A7A8A9AAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAEAFB0B1B2B3B4B5B6B7B8B9BAABACADAE
