如何在 Fedora 36 中重置 Root 密码
|
|||
|
|
======
|
|||
|
|
在 Fedora 中重置忘记的根密码。
|
|||
|
|
|
|||
|
|
你是否忘记了 Fedora 中的 root 密码？或者您想更改 Fedora 系统中的 root 用户密码？没问题！本简要指南将引导你完成在 Fedora 操作系统中更改或重置 root 密码的步骤。
|
|||
|
|
|
|||
|
|
**注意：** 本指南已在 Fedora 36 和 35 版本上进行了正式测试。下面提供的步骤与在 Fedora Silverblue 和旧 Fedora 版本中重置 root 密码的步骤相同。
|
|||
|
|
|
|||
|
|
**步骤 1** - 打开 Fedora 系统并按 **ESC** 键，直到看到 GRUB 启动菜单。出现 GRUB 菜单后，选择要引导的内核并点击 **e** 以编辑选定的引导条目。
|
|||
|
|
|
|||
|

|
|||
|
|
|
|||
|
|
**步骤 2** - 在下一个页面中，你将看到所有启动参数。找到名为 **ro** 的参数。
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
**步骤 3** - 将 **“ro”** 参数替换为 **“rw init=/sysroot/bin/sh”**（当然不带引号）。请注意 “`rw`” 和 “`init=/sysroot`...” 之间的空格。修改后，内核参数行应如下所示。
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
**步骤 4** - 如上更改参数后，按 **Ctrl+x** 进入紧急模式，即单用户模式。
|
|||
|
|
|
|||
|
|
在紧急模式下，输入以下命令以读/写模式挂载根（`/`）文件系统。
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
chroot /sysroot/
|
|||
|
|
```
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
**步骤 5** - 现在使用 `passwd` 命令更改 root 密码：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
passwd root
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
输入两次 root 密码。我建议你使用强密码。
|
|||

|
|||
|
|
|
|||
|
|
**步骤 6** - 重置 root 密码后，运行以下命令在重启时启用 SELinux 重新标记：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
touch /.autorelabel
|
|||
|
|
```
|
|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
**步骤 7** - 最后，退出单用户模式并通过运行以下命令将 Fedora 系统重启到正常模式：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
exit
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
reboot
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
等待 SELinux 重新标记完成。这将需要几分钟，具体取决于文件系统的大小和硬盘的速度。

|||

|||

|

|
**步骤 8** - 文件系统重新标记完成后，你可以使用新的 root 密码登录到你的 Fedora 系统。

如你所见，在 Fedora 36 中重置 root 密码的步骤非常简单，并且与**[在 RHEL 中重置 root 密码][9]**及其克隆版本（如 CentOS、AlmaLinux 和 Rocky Linux）完全相同。
