ubuntu各版本修改网卡配置

关于我从liunx到ubuntu一路摸索过来总结的一些知识..

17.10以前版本

文件路径：/etc/sysconfig/network-scripts/ifcfg-eth0(你的网卡)，设置网卡IP地址(也可以配置网关和DNS)

 # 静态分配的配置方法： # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto ens33 iface ens33 inet static address 192.168.1.8 # IP地址 netmask 255.255.255.0 # 子网掩码 gateway 192.168.1.1 # 网关 broadcast 192.168.1.255 # 广播地址 在IP中，如果最后一改数字时255,那一定是广播地址(可忽略) # 修改网卡的硬件地址： ifconfig ens33 hw ether 00:0c:29:f0:cf:f9 #(可忽略)

DEVICE="eth0" TYPE=Ethernet BOOTPROTO=static HWADDR=00:0C:29:4C:84:AB IPADDR=192.168.1.8 NETMASK=255.255.255.0 GATEWAY=192.168.1.1 DEFROUTE="yes" IPV4_FAILURE_FATAL="yes" IPV6INIT=no NAME="System eth0" NM_CONTROLLED=yes ONBOOT=yes PEERDNS=yes PEERROUTES="yes" UUID="5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03" USERCTL=no DNS1=202.106.0.20 DNS2=192.168.1.1

(2)/etc/sysconfig/network，设置网关

NETWORKING=yes HOSTNAME=localhost.localdomain GATEWAY=192.168.1.1

(3)/etc/resolv.conf，设置DNS

nameserver=202.106.0.20 nameserver=192.168.1.1 search localdomain

修改网络配置 17.10以后版本

文件路径：/etc/netplan/00-installer-config.yaml

可以多种格式配置

# This is the network config written by 'subiquity' network: ethernets: ens33: #配置的网卡的名称 addresses: [192.168.31.215/24] #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 gateway4: 192.168.31.1 #网关地址 nameservers: addresses: [192.168.31.1,114.114.114.114] #DNS服务器地址，多个DNS服务器地址需要用英文逗号分隔开 version: 2 renderer: networkd #指定后端采用systemd-networkd或者Network Manager，可不填写则默认使用systemd-workd routes: #默认路由 自己设置 - to: 172.18.0.0/16 via: 172.18.105.1
