Pi4b 8G版本安装centos7

一、准备工作

首先准备好内存卡，网线，读卡器，树莓派pi4b 8g机器一台

下载好SDformatter，Win32DiskImager软件

二、做完准备工作后，至​​​​​​​https://mirrors.huaweicloud.com/centos-altarch/7.9.2009/isos/armhfp/​​​下载CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2009-sda.raw.xz镜像

解压后得到一个CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2009-sda.raw文件夹，

进入后可以看到CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2009-sda.raw文件

三、安装

打开SDformatter软件

格式化tf卡

完成后打开Win32DiskImager

写入完成后把tf卡插入树莓派通电，并提前插好网线，进入路由器查看树莓派的IP地址

使用打开终端使用ssh命令链接例如：ssh root@192.168.31.243

开机进入后输入root，密码centos

进入系统

这时候我们先把将可用分区扩展到整个SD卡例如我的是64G卡

先使用df -f命令查看一下你自己的分区

在使用/usr/bin/rootfs-expand指令

df -h查看

三、软件安装

因为是最小安装所以很多软件都需要自己yum一下

先来安装vim

使用指令yum install vim

开始安装遇到提示都是输入y确定

之后是换源

先使用

yum clean all

sudo rm -rf /var/cache/yum

rm -rf /etc/yum.repos.d/*

清除原来的库

建立新库

​vim /etc/yum.repos.d/CentOS-Base.repo

把下列内容复制到打开的窗口内

​# 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.
