Ubuntu网络配置
网卡名称:
默认ubuntu的网卡名称和Cent OS 7类似,如:ens33,ens38等
修改网卡名称为传统命名方式:
修改配置文件为下面形式
vi /etc/default/grub
GRUB_CMDLINE_LINUX="net.ifnames=0"
生效新的grub.cfg文件
grub-mkconfig -o /boot/grub/grub.cfg :Centos里面是grub2
重启reboot
官网文档:
https://help.ubuntu.com/lts/serverguide/network-configuration.html.zh-CN
配置自动获取IP
cat /etc/netplan/01-netcfg.yaml
network:
version: 2
renderer:networkd
ethernets:
ens33:
dhcp4: yes
修改网卡配置文件后需执行命令生效:netplan apply
配置静态IP:
cat /etc/netplan/01-netcfg.yaml
network:
version: 2
renderer: networkd
ethernets:
eth0:
addresses:
- 192.168.6.10/24
- 10.10.10.10/24
gateway4: 192.168.6.1
nameservers:
search: [mydomain, otherdomain]
addresses: [223.5.5.5, 8.8.8.8, 1.1.1.1]
查看ip和gateway
ip addr
route -n
查看DNS
ls -l /etc/resolv.conf
lrwxrwxrwx 1 root root 39 Dec 12 11:36 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf
systemd-resolve –status
修改主机名
hostnamectl set-hostname ubuntu1804
