1.切换root
sudo su
2.禁用 Cloud-Init 的网络配置
创建99-disable-network-config.cfg
vi /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
network: {config: disabled}
3.查看网卡名称
ip a
4.移除50-cloud-init.yaml ，创建 00-installer-config.yaml
网卡名称从上面获取，根据实际情况修改， ip和网关根据规划修改
进入目录： cd /etc/netplan
root@yd101:/etc/netplan# cat 00-installer-config.yaml network: version: 2 ethernets: ens3: dhcp4: no addresses: - 192.168.5.2/24 gateway4: 192.168.5.1 nameservers: addresses: [8.8.8.8, 114.114.114.114]
5. 生效配置
部分告警忽略

6.确认ip地址
通过其他方式远程连接服务器验证
ssh 用户@ip
补充：
1. 查看网口是否启动
ip link show eth0 | grep -o "LOWER_UP"
2.强制启动接口
ip link set dev <网卡名> up
3.重启网络
systemctl restart systemd-networkd
