树莓派安装centos并配置wifi

树莓派安装centos并配置wifi

烧录centos镜像到树莓派。

1.连接centos

1.找根网线连接到树莓派
2.识别全部空间

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

3.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

2.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
或 systemctl enable NetworkManager 

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
