[开发工具]ubuntu和centos手动配置网卡信息

一.ubuntu系统：执行sudo vim /etc/netplan/00-installer-config.yaml：

network:
  ethernets:
    eno1:
      dhcp4: false #这里默认配置是“true”
      addresses:
        - 192.168.1.2/24
      gateway4: 192.168.1.254
      nameservers:
        addresses: [61.139.2.69, 223.5.5.5]
#下面是配置网卡桥接模式，如果是桥接模式那么物理网卡不需要配置ip地址信息      
network:
  ethernets:
    eno1:
      dhcp4: false
  bridges:
    br0:
      interfaces: [eno1]
      addresses:
        - 192.168.1.2/24
      gateway4: 192.168.1.254
      nameservers:
        addresses: [61.139.2.69, 223.5.5.5]
  version: 2

修改成功后执行sudo netplan apply应用配置即可。

二.centos系统：执行vim /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="static" #这里默认配置是“dhcp“”
IPADDR="192.168.1.2"   
NETMASK="255.255.255.0"    
GATEWAY="192.168,1.254"    
DNS1="223.5.5.5"   
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="81e87b75-88f5-4649-bc44-aa703fe3a0fc"
DEVICE="ens33"
ONBOOT="yes"

下面是配置网卡桥接模式，首先新建桥接设备vim /etc/sysconfig/network-scripts/ifcfg-br0

DEVICE="br0"
ONBOOT="yes"
TYPE="Bridge"
BOOTPROTO="static"
IPADDR="192.168.1.2"   
NETMASK="255.255.255.0"    
GATEWAY="192.168,1.254"    
DNS1="223.5.5.5"   
DEFROUTE="yes"
#配置物理网卡vim /etc/sysconfig/network-scripts/ifcfg-ens33
DEVICE="ens33"
ONBOOT="yes"
BOOTROTO="yes"
BRIDGE="br0"  #指定桥接设备

修改成功后执行systemctl restart network重启网络服务即可。
