Ubuntu Server 24.04 配置静态IP

提示：基于Ubuntu Server 24.04进行配置

一、查看网卡信息

使用命令 ip a
lo 为本地回环地址
ens33 真实网卡地址

shanfeng@ubuntu:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00inet 127.0.0.1/8 scope host lovalid_lft forever preferred_lft foreverinet6 ::1/128 scope host noprefixroute valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000link/ether 00:0c:29:2e:eb:4b brd ff:ff:ff:ff:ff:ffaltname enp2s1inet 192.168.10.3/24 brd 192.168.10.255 scope global ens33valid_lft forever preferred_lft foreverinet6 fe80::20c:29ff:fe2e:eb4b/64 scope link valid_lft forever preferred_lft forever

二、修改网卡信息

sudo vi /etc/netplan/50-cloud-init.yaml
注意：一定要加sudo 否则修改完成后 无法保存

network:ethernets:ens33: # 网卡名称addresses: [192.168.10.3/24]  # 要配置的静态IP地址   /24 代表子网掩码为 255.255.255.0gateway4: 192.168.10.2        # 网关地址  根据真实情况填写dhcp4: false					# 是否启用dhcp  因为配置静态IP 所以这里是flasenameservers:					# 配置dns addresses: [223.5.5.5,114.114.114.114,8.8.8.8]version: 2renderer: networkd				# 这行一定要加 不加报错

三、使网卡配置生效

shanfeng@ubuntu:~$ sudo netplan apply

四、测试

shanfeng@ubuntu:~$ ping www.baidu.com
