树莓派4B 安装 CentOS 7 64位 AltArch 系统(aarch64)

最近买了个新玩具 树莓派4B ，安装个 CentOS 当第二博客

• 一、下载镜像
• 二、烧入镜像
• 三、配置 WiFi

一、下载镜像

1.清华大学镜像

• 64 位

https://mirrors.tuna.tsinghua.edu.cn/centos-altarch/7.8.2003/isos/aarch64/images/CentOS-Userland-7-aarch64-RaspberryPI-Minimal-4-2003-sda.raw.xz

• 32 位

https://mirrors.tuna.tsinghua.edu.cn/centos-altarch/7.8.2003/isos/armhfp/CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2003-sda.raw.xz

2.CentOS 官网

https://people.centos.org/pgreco/CentOS-Userland-7-aarch64-generic-Minimal-2003-mbr/CentOS-Userland-7-aarch64-generic-Minimal-2003-sda.raw.xz

3.阿里云镜像

• 64 位

https://mirrors.aliyun.com/centos-altarch/7.8.2003/isos/aarch64/images/CentOS-Userland-7-aarch64-RaspberryPI-Minimal-4-2003-sda.raw.xz

• 32 位

https://mirrors.aliyun.com/centos-altarch/7.8.2003/isos/armhfp/CentOS-Userland-7-armv7hl-RaspberryPI-Minimal-4-2003-sda.raw.xz

国内下载 清华大学 或 阿里云 速度快一点

二、烧入镜像

1.使用内存卡修复工具 SDFormatter.exe 格式化内存卡

格式化 sd卡，切记不要用 Windows 自带的格式化！！！没用

2.使用磁盘映像工具 win32diskimager-1.0.0-install.exe 烧入 sd卡 即可，需要先解压下载好的文件，烧录后缀名为 .raw 的文件

烧入之后，直接插入树莓派开机使用

查看路由器获取到的 IP，或者用显示器登录查看

默认账号 root ,密码 centos

3.识别全部空间

$ /usr/bin/rootfs-expand
#默认是没有全部识别到 TF 卡的

4.验证

$ cat /etc/redhat-release 
CentOS Linux release 7.8.2003 (AltArch)
$ uname -a
Linux home_jarbo 5.4.28-v8.1.el7 #1 SMP PREEMPT Mon Mar 30 21:28:10 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux
$ getconf LONG_BIT
64

三、配置 WiFi

1.查看网络包是否安装

$ rpm -qa | grep NetworkManager
NetworkManager-libnm-1.18.4-3.el7.aarch64
NetworkManager-team-1.18.4-3.el7.aarch64
NetworkManager-wifi-1.18.4-3.el7.aarch64
NetworkManager-1.18.4-3.el7.aarch64
NetworkManager-tui-1.18.4-3.el7.aarch64

2.设置 NetworkManager 自动启动

$ chkconfig NetworkManager on

3.安装 NetworkManager-wifi

$ yum -y install NetworkManager-wifi

4.开启 WiFi

$ nmcli r wifi on

5.测试（扫描信号）

$ nmcli dev wifi

6.连接

$ nmcli dev wifi connect SSID password <password>
$ nmcli dev wifi connect FBI password FBICOMEING123456
