先ping一下确保ip没被占用。确认下自己的网卡名字下面。ip addr如下面wlp2s0就是我的网卡名啦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 ....

- 下面是固定ip:192.168.0.100 的操作:
一、Ubuntu固定IP:
- 配置文件在 /etc/netplan 下,yaml文件:
cd /etc/netplan
- 修改配置文件内容为:
network:
version: 2
ethernets:
wlp2s0:
dhcp4: no
dhcp6: no
addresses: [192.168.0.100/24]
gateway4: 192.168.0.1
nameservers:
addresses: [114.114.114.114, 8.8.8.8]
禁用dhcp自动分配ip
键 | 描述 |
---|---|
addresses | 子网ip |
gateway4 | 网关地址 |
nameservers | dns服务器 |
- 应用配置生效
sudo netplan apply
- 查看ip
ip addr
二、Centos固定IP:
- 配置文件在 /etc/sysconfig/network-scripts 下,一般为 ifcfg-{网卡名}:
cd /etc/sysconfig/network-scripts
- 禁用dhcp协议,改为静态ip方式:
#BOOTPROTO="dhcp"
BOOTPROTO="static"
- 增加下面内容
IPADDR=192.168.0.181
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
DNS1=114.114.114.114
DNS2=8.8.8.8
键 | 描述 |
---|---|
IPADDR | 子网ip |
NETMASK | 子网掩码 |
GATEWAY | 网管地址 |
DNS1/DNS2 | dns服务器 |
- 应用配置生效
sudo service network restart
- 查看ip
ip addr
