news 来源：原创 2025/5/9 10:13:48

1.配置文件

# 默认配置文件：/etc/netplan/*.yaml# 本机
root@ubuntu-server:~# vim /etc/netplan/50-cloud-init.yaml

2.DHCP

network:             ethernets:ens33:dhcp4: trueversion: 2

3.静态IP设置

注意：netplan 说明文件格式存储在下列路径下，该目录下有各种样例文件，可以提供帮助

root@ubuntu-server:~# cd  /usr/share/doc/netplan/examples/
root@ubuntu-server:/usr/share/doc/netplan/examples# lsbonding_router.yaml               infiniband.yaml          sriov_vlan.yam    ……# 静态IP范例
root@ubuntu-server:/usr/share/doc/netplan/examples# cat static.yaml

查看本机IP信息
