ubuntu 22.04中配置静态IP

 

001、 系统

root@ubuntu01:/etc/netplan# lsb_release -a
No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 22.04.1 LTS
Release:    22.04
Codename:    jammy

 

 

002、网络模式，nat模式

 

 

003、配置静态IP， 修改配置文件：/etc/netplan/01-network-manager-all.yaml（提前对文件进行备份，防止出现意外）

修改文件内容为：

network:
  version: 2
    #renderer: NetworkManager
  ethernets:
    ens32:    #配置的网卡的名称， 此处的网卡一英语虚拟机一致，可以使用ifconfig命令查看
      addresses: [192.168.74.129/24]    #配置的静态ip地址和掩码
      dhcp4: no    #关闭DHCP，如果需要打开DHCP则写yes
      optional: true
      routes:
        - to: default
          via: 192.168.74.2    #网关地址， 此处NAT模式，最后的网关为2.
      nameservers:
         addresses: [114.114.114.114]    #DNS服务器地址，多个DNS服务器地址需要用
英文

 

 

004、使配置生效

root@ubuntu01:/etc/netplan# netplan apply

 

 

005、查看IP，测试网络

root@ubuntu01:/etc/netplan# netplan apply   ## 使配置生效
root@ubuntu01:/etc/netplan# ifconfig | head     ## 查看ip
