armbian开启ssh_Armbian Ubuntu启用netplan配置网络

OrangePi安装Armbian Ubuntu镜像，默认使用内置的armbian-config来设置网络，需要SSH登录才能设置。

如果需要采用Ubuntu下常见的netplan配置，则需要安装netplan，当前镜像版本是Ubuntu Focal (20.04)

# 安装netplan

sudo apt install netplan.io

# 新建配置文件

sudo touch /etc/netplan/50-cloud-init.yaml

开始写配置之前，要先了解一下当前设备的网卡名称！

# 查看IP信息

ip a

# lo是环回地址

# eth0是有线网卡地址

# wlan0是无线网卡地址

设置eth0为静态地址

保存配置后，需要应用配置才能生效

sudo netplan apply
