如下：

/etc/netplan/50-cloud-init.yaml這個檔案。

[email protected]:~# vim /etc/netplan/50-cloud-init.yaml 
[email protected]:~# cat /etc/netplan/50-cloud-init.yaml 
# This file is generated from information provided by

# 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:
        ens33:
            addresses: [192.168.2.100/24]
            dhcp4: no
            gateway4: 192.168.2.1
            nameservers :
                    addresses: [8.8.8.8]
    version: 2
 

然後應用一下：
