ubuntu图形化界面设置有线网卡相关信息

以下为命令行配置方法

3. 先确认要修改的网卡配置

oucanrong@zcwyou:~$ ip addr

1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

inet 127.0.0.1/8 scope host lo

valid_lft forever preferred_lft forever

inet6 ::1/128 scope host

valid_lft forever preferred_lft forever

2: enp0s25: mtu 1500 qdisc fq_codel state UP group default qlen 1000

link/ether 3c:97:0e:43:e8:bd brd ff:ff:ff:ff:ff:ff

inet 192.168.22.196/24 brd 192.168.22.255 scope global dynamic noprefixroute enp0s25

valid_lft 858311sec preferred_lft 858311sec

inet6 fe80::b4be:f7d9:ccda:d18d/64 scope link noprefixroute

valid_lft forever preferred_lft forever

假设我的网卡标识号为enp0s25

4. 修改配置文件/etc/network/interfaces

zcwyou@ubuntu1804:~$ sudo vi /etc/network/interfaces

假设enp0s25的IP地址为192.168.178.100，子网掩码为255.255.255.0，网关为192.168.178.1

添加以下内容：

auto enp0s25 iface enp0s25 inet static address 192.168.178.100 netmask 255.255.255.0 gateway 192.168.178.1

解释配置内容

auto enp0s25 #设置自动启动enp0s25接口

iface enp0s25 inet static #配置静态IP

address 192.168.178.100 #IP地址

netmask 255.255.255.0 #子网掩码

gateway 192.168.178.1 #默认网关

5. 修改DNS信息

zcwyou@ubuntu1804:~$ sudo vi /etc/resolve.conf

修改为以下内容

nameserver 127.0.0.1 nameserver 223.5.5.5

解释：

223.5.5.5为阿里的DNS服务器

6. 重启网络，使配置生效

sudo /etc/init.d/networking restart

oucanrong@zcwyou:~$ sudo systemctl restart networking oucanrong@zcwyou:~$ sudo netplan apply

7. 验证配置结果

oucanrong@zcwyou:~$ ip addr

ubuntu验证IP地址

ubuntu测试新IP地址连通性
