树莓派学习笔记——（3）配置wifi

通过LAN连接树莓派并不方便，下面需要连接wifi

首先看一下网卡的状态，可以看到wlan0处于disconnected状态。

[root@localhost ~]# nmcli dev status
DEVICE         TYPE      STATE         CONNECTION         
eth0           ethernet  connected     Wired connection 1 
wlan0          wifi      disconnected  --                 
p2p-dev-wlan0  wifi-p2p  disconnected  --                 
lo             loopback  unmanaged     --                 

安装包

[root@localhost ~]# yum install -y NetworkManager-wifi

开启wifi

[root@localhost ~]# nmcli r wifi on

扫描wifi

[root@localhost ~]# nmcli dev wifi

连接wifi

[root@localhost ~]# nmcli --ask dev wifi connect SSID　　#SSID替换为wifi的名字

查看连接

[root@localhost ~]# nmcli conn

配置网卡文件

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-SSID
ONBOOT=yes    #设置开机启动
