一、配置静态IP地址

Ubuntu从17.10开始，放弃在/etc/network/interfaces里面配置IP，改为在 /etc/netplan/01-network-manager-all.yaml的yaml文件中配置IP地址。查看网络配置信息。

在Ubuntu20.04中，默认没有安装ifconfig，因此使用ip addr命令。

1、ubuntu20.04修改配置文件

root@lolaage-virtual-machine:~  network: ethernets: ens33:  addresses: <span class="token punctuation">[</span><span class="token number">192.168</span>.1.62/24<span class="token punctuation">]</span>  dhcp4: <span class="token boolean">false</span>  optional: <span class="token boolean">true</span> gateway4: <span class="token number">192.168</span>.1.1  nameservers: addresses: <span class="token punctuation">[</span><span class="token number">8.8</span>.8.8,114.114.114.114<span class="token punctuation">]</span>  version: <span class="token number">2</span> renderer: NetworkManager 
root@lolaage-virtual-machine:~  network: ethernets: ens33:  addresses: <span class="token punctuation">[</span><span class="token number">192.168</span>.1.62/24<span class="token punctuation">]</span>  dhcp4: <span class="token boolean">false</span>  optional: <span class="token boolean">true</span> gateway4: <span class="token number">192.168</span>.1.1  nameservers: addresses: <span class="token punctuation">[</span><span class="token number">8.8</span>.8.8,114.114.114.114<span class="token punctuation">]</span>  version: <span class="token number">2</span> renderer: NetworkManager 
root@lolaage-virtual-machine:~  network: ethernets: ens33:  addresses: [192.168.1.62/24]  dhcp4: false  optional: true gateway4: 192.168.1.1  nameservers: addresses: [8.8.8.8,114.114.114.114]  version: 2 renderer: NetworkManager 

2、ubuntu22.04修改配置文件

 network: ethernets: ens33:  addresses: <span class="token punctuation">[</span><span class="token number">192.168</span>.1.67/24<span class="token punctuation">]</span>  dhcp4: <span class="token boolean">false</span>  optional: <span class="token boolean">true</span> routes: - to: default via: <span class="token number">192.168</span>.1.1 nameservers: addresses: <span class="token punctuation">[</span><span class="token number">8.8</span>.8.8,114.114.114.114<span class="token punctuation">]</span>  version: <span class="token number">2</span> renderer: NetworkManager 
 network: ethernets: ens33:  addresses: <span class="token punctuation">[</span><span class="token number">192.168</span>.1.67/24<span class="token punctuation">]</span>  dhcp4: <span class="token boolean">false</span>  optional: <span class="token boolean">true</span> routes: - to: default via: <span class="token number">192.168</span>.1.1 nameservers: addresses: <span class="token punctuation">[</span><span class="token number">8.8</span>.8.8,114.114.114.114<span class="token punctuation">]</span>  version: <span class="token number">2</span> renderer: NetworkManager 
 network: ethernets: ens33:  addresses: [192.168.1.67/24]  dhcp4: false  optional: true routes: - to: default via: 192.168.1.1 nameservers: addresses: [8.8.8.8,114.114.114.114]  version: 2 renderer: NetworkManager 

2、配置生效

root@lolaage-virtual-machine:~ 
root@lolaage-virtual-machine:~ 
root@lolaage-virtual-machine:~ 

3、查看网卡信息

root@lolaage-virtual-machine:~ 
root@lolaage-virtual-machine:~ 
root@lolaage-virtual-machine:~ 

如下图所示：
