CentOS GRUB配置语言设置教程-HCRM博客

在CentOS系统中,GRUB（GRand Unified Bootloader）是一个用于启动操作系统的程序，配置GRUB可以帮助用户设置默认启动项、选择启动语言以及管理启动菜单，以下是如何在CentOS中配置GRUB语言的相关步骤和说明。

GRUB配置概述

GRUB配置文件通常位于/etc/grub.d/目录下，主要的配置文件是grub.conf，在这个文件中，可以通过设置lang变量来指定启动菜单的语言。

编辑GRUB配置文件

需要编辑GRUB配置文件,可以使用文本编辑器如vi或nano来编辑。

sudo nano /etc/grub.d/grub.conf

设置语言环境

在grub.conf文件中，找到lang变量并设置你希望的语言，设置英语（美国）作为启动菜单的语言：

lang en_US.UTF-8

确保将en_US.UTF-8替换为你需要的语言编码。

保存并退出编辑器

编辑完成后,保存并退出编辑器，对于nano编辑器，你可以按Ctrl+O保存文件，然后按Ctrl+X退出；对于vi编辑器，你可以按Esc键，然后输入wq保存并退出。

更新GRUB配置

编辑完配置文件后,需要更新GRUB配置，以便系统识别新的设置。

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

重启系统

为了使新的GRUB配置生效,需要重启系统。

sudo reboot

格式化配置文件

为了更清晰地展示配置文件的内容,以下是一个格式化后的grub.conf文件示例：

# grub.conf generated by anaconda
#
#   Set GRUB_TIMEOUT to zero or a positive number of seconds to disable the
#   graphical menu.  If you don't want GRUB to display the menu at all, you
#   can set this to -1.
GRUB_TIMEOUT=0
#   Set GRUB_DISTRIBUTOR to your Linux distribution name, with the modified
#   value appended to the default setting of %D.  See below for a list of
#   supported distributors.
GRUB_DISTRIBUTOR="CentOS"
#   Uncomment to enable a new option in the GRUB menu: "Hide all but the default
#   operating system (hidden)"
GRUB_HIDDEN_TIMEOUT=0
#   Uncomment to disable graphical menu.  Uncommenting this option will remove
#   the graphical menu and the option to choose the operating system to boot.
GRUB_HIDDEN_TIMEOUT_QUIET=0
#   Uncomment to disable recovery mode in GRUB (do not show a recovery menu)
#   GRUB_DISABLE_RECOVERY="true"
#   Uncomment to specify the default entry to boot, such as 'Windows 7' or
#   'Advanced Options for CentOS Linux'.  You can use the F10 key to change
#   the default at the moment the menu is displayed.
default=0
#   Uncomment to disable automatic search for a kernel image.  Then, you must
#   manually specify the kernel image on the command line.
#   For information on how to specify the right kernel image, see below.
#   For Linux kernels, you need to specify the kernel image name, not the
#   directory it is in.
#   For example:
#   kernel /vmlinuz-version ro root=/dev/sda5
#   You will need to add the 'root=' tag and the initrd if required.
#   GRUB_DISABLE_LINUX_Splash=true
#   Uncomment to disable all messages when booting.  You will need to enable
#   'GRUB_HIDDEN_TIMEOUT' as well.
#   GRUB_DISABLE_INFO_SCREEN=true
#   Uncomment if you want to hide the menu.  You will then need to enter the
#   menuitem's exact title in the kernel command line.
#   For example, the entry title below might be 'Advanced options for CentOS Linux':
#   menuentry 'Advanced options for CentOS Linux' --class gnu-linux --class gnu --class os {
#     linux /vmlinuz-version ro root=/dev/sda5
#     initrd /initrd-version.img
#   }
#   GRUB_HIDDEN_MENU=true
#   Uncomment to specify the language to be used for grub's boot menu.
lang en_US.UTF-8
#   You can have multiple entries.  It appears as a list in the GRUB boot menu:
#   menuentry "Text Mode" {
#     linux /vmlinuz-version console=ttyS0,115200n8
#     initrd /initrd-version.img
#   }
#   menuentry "High Contrast Text Mode" {
#     linux /vmlinuz-version console=ttyS0,115200n8 console letterSpacing=8
#     initrd /initrd-version.img
#   }
#   menuentry "Graphics Mode" {
#     linux /vmlinuz-version
#     initrd /initrd-version.img
#   }
