CentOS7用U盘安装

Edited on In ,

安装

$\color{red}{这是为的关于centos7的第一篇文章，}$
$\color{red}{你可能觉得为说的不够详细，}$
$\color{red}{但是，请你相信我，}$
$\color{red}{我每次重装系统都是按照自己的流程走下来的}$
$\color{red}{看我的文集就会发现好多我们想要的，并且为已经踩过的坑}$
$\color{red}{坑踩多了就变成了路}$
#####如果是虚拟机，请右拐。
#####如果是双系统，建议把另一个系统盘禁用，或把盘拿掉。

制作映像U盘右拐

U盘启动后，根据不同的系统引导模式，会有两种不同的安装引导页面（大同小异）

  • 上下转到 Install CentOS 7
  • 按Tab 键或者Ctrl+e
  • 在 vmlinuz 后面添加 initrd=initrd.img linux dd quiet （每个空都是单空格），回车执行（或者Ctrl + x 执行，看下面有没有说明）
  • 找到自己的启动盘的盘符,比如/dev/sda1
  • 关机-开机 （如果是重起，有可能找不到U盘，会让自己感觉自己记错了U盘的盘符）
  • 上下转到 Install CentOS 7
  • 按Tab 键或者Ctrl+e
  • 在 vmlinuz 后面添加 initrd=initrd.img inst.stage2=hd:/dev/sdc4 quiet（每个空都是单空格），回车执行（或者Ctrl + x 执行，看下面有没有说明）
  • 好了，你已经进入安装模式了，怎么安装，请右拐，右拐是百度、google、必应

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
