Linux实践归纳 | Ubuntu18.04-LTS配置静态IP

由于博主是在ARM板上配置静态ip，ARM平台使用的是Ubuntu18.04-LTS系统，在参考其他博主的文章后，发现Ubuntu18版本与16版本的网络配置有点不一样，通过折腾一个下午，终于配置成功并成功ping通外网！

1、01-network-manager-all.yaml文件配置

cd进入到/etc/netplan/目录下，执行vim 01-network-manager-all.yaml命令，如果没有netplan目录或者01-network-manager-all.yaml文件，自行创建即可。参考以下内容：

#Let NetworkManager manage all devices on this system
network:
  version: 2
#  renderer: NetworkManager
  ethernets:
          eth0:
                  addresses: [168.168.100.111/16]
                  gateway4:  168.168.0.1
                  dhcp4: no
                  dhcp6: no
                  nameservers: 
                        addresses: [127.0.0.53, 114.114.114.114, 114.114.115.115, 8.8.8.8, 8.8.4.4]

• eth0为网络设备接口名称，addressed为需要配置的ip地址信息，后面的16为子网掩码,代表255.255.0.0，需要用命令ifconfig -a查看自己的网络信息进行配置
• gateway4为ip4网关，不清楚网关可执行命令route -n进行查看
• nameservers下addresses为DNS地址，国内一般选择114.114.114.114或者114.114.115.115

2、resolved.conf文件配置

cd进入到/etc/systemd/目录下，执行vim resolved.conf命令，参考以下内容：

#

[Resolve]
DNS=127.0.0.53 114.114.114.114 114.114.115.115 8.8.8.8 8.8.4.4
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#Cache=yes
#DNSStubListener=yes
