-How to Change the default kernel in RHEL 8 and 9
-======
-
-Usually a Linux system boots with the latest installed kernel, which is set by default. It keeps maximum 3 recent versions of Linux Kernel boot entries.
-
-Let’s say you’ve done the yum update, and a new kernel is installed as part of this update. This prevents the application from starting as this kernel is incompatible with the application.
-
-To temporarily fix this problem, you should continue to boot the system into an older kernel.
-
-In this article, we’ll show you how to set old kernel version as default on RHEL 8 and RHEL 9 systems using grubby utility.
-
-  * [**How to Upgrade from RHEL 7 to RHEL 8**][1]
-
-
-
-### What is grubby
-
-grubby is a command line tool used for updating and displaying information about the boot loaders configuration files across multiple architectures.
-
-### Checking currently booted kernel
-
-You can check booted/loaded kernel using **uname command** as shown below.
-
-```
-
-    uname -r
-
-    4.18.0-477.13.1.el8_8.x86_64
-
-```
-
-### Listing the Default Kernel
-
-To verify the default kernel version using grubby, run:
-
-```
-
-    grubby --default-kernel
-
-    /boot/vmlinuz-4.18.0-477.13.1.el8_8.x86_64
-
-```
-
-To obtain the index number of the current default kernel, run:
-
-```
-
-    grubby --default-index
-    0
-
-```
-
-### Checking installed kernels
-
-To check list of installed kernels, run:
-
-Let’s explain the below output. The latest kernel installed will have the **entry-index** of **`0`** , the next **older kernel** version will get **`1`** , second older kernel version will get **`2`** , and the **rescue kernel** will get an entry-index of **`3`**.
-
-```
-
-    grubby --info=ALL | egrep -i 'index|title'
-
-    index=0
-    title="Red Hat Enterprise Linux (4.18.0-477.13.1.el8_8.x86_64) 8.8 (Ootpa)"
-    index=1
-    title="Red Hat Enterprise Linux (4.18.0-425.19.2.el8_7.x86_64) 8.7 (Ootpa)"
-    index=2
-    title="Red Hat Enterprise Linux (4.18.0-425.13.1.el8_7.x86_64) 8.7 (Ootpa)"
-    index=3
-    title="Red Hat Enterprise Linux (0-rescue-13iu76884ec5490puc67j8789s249b0c) 8.2 (Ootpa)"
-
-```
-
-### Changing default kernel Boot entry
-
-This can be done in two ways either using **`'kernel filename'`** or **`'kernel entry-index'`**. We will be going to set ‘ **index=1 (4.18.0-425.19.2.el8_7.x86_64)** ‘ as default kernel due to application dependency.
-
-```
-
-    Syntax:
-    grubby --set-default [kernel-filename]
-
-```
-
-```
-
-    grubby --set-default /boot/vmlinuz-4.18.0-425.19.2.el8_7.x86_64
-    OR
-    grubby --set-default vmlinuz-4.18.0-425.19.2.el8_7.x86_64
-
-```
-
-To change the default kernel boot entry using kernel entry-index:
-
-```
-
-    Syntax:
-    grubby --set-default-index=[kernel-entry-index]
-
-```
-
-```
-
-    grubby --set-default-index=1
-
-```
-
-### Rebooting the system
-
-Reboot the system to check whether the old kernel is persistent or not.
-
-```
-
-    reboot
-    or
-    init 6
-
-```
-
-### Verifying the Changes
-
-Let’s check if the kernel added in the previous step has taken effect or not. Yes, it booted with older kernel **`'N-1'`** as expected.
-
-```
-
-    uname -r
-    4.18.0-425.19.2.el8_7.x86_64
-
-    grubby --default-kernel
-    /boot/vmlinuz-4.18.0-425.19.2.el8_7.x86_64
-
-```
-
-To check detailed information of all kernel, run:
-
-```
-
-    grubby --info=ALL
-
-```

+
+如何更改 RHEL 8 和 9 的默认内核
+======
+
+通常 Linux 系统会默认引导系统进入最新安装的内核，并保留最新的 3 个 Linux 内核引导条目。
+
+假设你已经执行了 yum update，并且新的内核作为更新的一部分已经安装了。这时，由于这个新内核与应用程序不兼容，它会阻止应用程序启动。
+
+想要暂时解决这个问题，你应该还是引导系统进入旧内核。
+
+在本文中，我们将向您展示如何使用 grubby 工具将旧的内核版本设置为 RHEL 8 和 RHEL 9 系统上的默认版本。
+
+* [**如何从 RHEL 7 升级到 RHEL 8？**][1]
+
+
+
+### grubby 是什么
+
+grubby 是一个命令行工具，用于在多个架构上更新和显示引导加载配置文件的信息。
+
+### 检查当前引导的内核
+
+你可以使用如下的 ``uname`` 命令来检查当前引导/加载的内核。
+
+```
+
+    uname -r
+
+    4.18.0-477.13.1.el8_8.x86_64
+
+```
+
+### 列出默认内核
+
+使用 grubby 验证默认内核版本，运行以下命令：
+
+```
+
+    grubby --default-kernel
+
+    /boot/vmlinuz-4.18.0-477.13.1.el8_8.x86_64
+
+```
+
+要获取当前默认内核的索引号，请运行以下命令：
+
+```
+
+    grubby --default-index
+    0
+
+```
+
+### 检查已安装的内核
+
+要检查已安装的内核的列表，请运行以下命令：
+
+我们来解释以下的输出信息。最新安装的内核的**条目索引**为**`0`**，接下来的 **较旧的内核** 版本将会是  **`1`**，第二个更旧的内核版本将会是**`2`**，而**救援内核** 的条目索引将会是 **`3`**。
+
+```
+
+    grubby --info=ALL | egrep -i 'index|title'
+
+    index=0
+    title="Red Hat Enterprise Linux (4.18.0-477.13.1.el8_8.x86_64) 8.8 (Ootpa)"
+    index=1
+    title="Red Hat Enterprise Linux (4.18.0-425.19.2.el8_7.x86_64) 8.7 (Ootpa)"
+    index=2
+    title="Red Hat Enterprise Linux (4.18.0-425.13.1.el8_7.x86_64) 8.7 (Ootpa)"
+    index=3
+    title="Red Hat Enterprise Linux (0-rescue-13iu76884ec5490puc67j8789s249b0c) 8.2 (Ootpa)"
+
+```
+
+### 更改默认内核引导条目
+
+我们可以用两种方式，使用 **`'内核文件名'`**，或者使用 **`'内核条目索引'`**。我们设置“ ** index =1 (4.18.0-425.19.2.el8_7.x86_64)** ”为默认内核，以此满足应用程序的依赖关系。
+
+```
+
+    语法：
+    grubby --set-default [kernel-filename]
+
+```
+
+```
+
+    grubby --set-default /boot/vmlinuz-4.18.0-425.19.2.el8_7.x86_64
+    或者
+    grubby --set-default vmlinuz-4.18.0-425.19.2.el8_7.x86_64
+
+```
+
+使用内核条目索引更改默认的内核引导：
+
+```
+
+    语法：
+    grubby --set-default-index=[kernel-entry-index]
+
+```
+
+```
+
+    grubby --set-default-index=1
+
+```
+
+### 重启系统
+
+重启系统，检查旧内核是否持久更改。
+
+```
+
+    reboot
+    或者
+    init 6
+
+```
+
+### 验证更改
+
+让我们检查一下在上一步中添加的内核是否生效了。好了，按我们的预期使用了较旧的内核 **`'N-1'`** 进行引导了。
+
+```
+
+    uname -r
+    4.18.0-425.19.2.el8_7.x86_64
+
+    grubby --default-kernel
+    /boot/vmlinuz-4.18.0-425.19.2.el8_7.x86_64
+
+```
+
+要检查所有内核的详细信息，请运行以下命令：
+
+```
+
+    grubby --info=ALL
+
+```
+
+![][2]
+
+##### 总结
+
+在本教程中，我们展示了如何使用 grubby 工具在 RHEL 8 和 RHEL 9 系统上将旧版本内核设置为默认。
