树莓派是自带有无线网卡的,因此能够链接 wifi。shell
本文的树莓派系统环境是 Ubuntu Server 20.04,其余 Linux 系统都大同小异。vim
ssh 进入树莓派。app
sudo tzselect # 选择4 Aisa # 而后选择9 China # 接着选择1 Beijing Time # 最后选择1 确认 sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
设置完成后执行 date -R
看时间是否准确。ssh
cd /etc/netplan/ sudo vim 50-cloud-init.yaml
打开后应该会有如下内容:ide
# This file is generated from information provided by the datasource. Changes # to it will not persist across an instance reboot. To disable cloud-init's # network configuration capabilities, write a file # /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following: # network: {config: disabled} network: ethernets: eth0: dhcp4: true optional: true version: 2
如今须要加一个wifi的配置,示例以下:debug
# This file is generated from information provided by the datasource. Changes # to it will not persist across an instance reboot. To disable cloud-init's # network configuration capabilities, write a file # /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following: # network: {config: disabled} network: ethernets: eth0: dhcp4: true optional: true wifis: wlan0: dhcp4: true access-points: <wifi名字>: password: "<wifi密码>" version: 2
编辑完成后保存,而后执行命令3d
sudo netplan --debug apply
3.检查设置code
执行命令 ifconfig
检查是否有网卡 wlan0 的信息,而且获取到了ip,最后经过这个ip进行 ssh 链接,若是链接成功,那就没有问题了。orm
