树莓派鼓捣记
树莓派是自带有无线网卡的,所以可以连接 wifi。
本文的树莓派系统环境是 Ubuntu Server 20.04,其他 Linux 系统都大同小异。
ssh 进入树莓派。
1.第一步设置时区
sudo tzselect
# 选择4 Aisa
# 然后选择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。
2.设置 wifi
cd /etc/netplan/
sudo vim 50-cloud-init.yaml
打开后应该会有以下内容:
# 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
现在需要加一个wifi的配置,示例如下:
# 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,然后执行命令
sudo netplan --debug apply
3.检查设置
执行命令 ifconfig
检查是否有网卡 wlan0 的信息,并且获取到了ip,最后通过这个ip进行 ssh 连接,如果连接成功,那就没有问题了。
