樹莓派是自帶有無線網卡的,因此能夠鏈接 wifi。shell
本文的樹莓派系統環境是 Ubuntu Server 20.04,其餘 Linux 系統都大同小異。vim
ssh 進入樹莓派。app
sudo tzselect # 選擇4 Aisa # 而後選擇9 China # 接着選擇1 Beijing Time # 最後選擇1 確認 sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
設置完成後執行 date -R
看時間是否準確。ssh
cd /etc/netplan/ sudo vim 50-cloud-init.yaml
打開後應該會有如下內容: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
如今須要加一個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密碼>" version: 2
編輯完成後保存,而後執行命令3d
sudo netplan --debug apply
3.檢查設置code
執行命令 ifconfig
檢查是否有網卡 wlan0 的信息,而且獲取到了ip,最後經過這個ip進行 ssh 鏈接,若是鏈接成功,那就沒有問題了。orm
