Ubuntu 18.04 配置固定IP和DNS

 

1.修改静态IP地址

root@ubuntu:/etc/netplan# pwd
/etc/netplan
root@ubuntu:/etc/netplan# ls
50-cloud-init.yaml

编辑50-cloud-init.yaml

root@ubuntu:/etc/netplan# cat 50-cloud-init.yaml 
# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init‘s
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        eth0:
            addresses: [172.16.5.140/24]
            gateway4: 172.16.5.254
            dhcp4: true
            optional: true
    version: 2

以上会把IP配置为,172.16.5.140,DNS为172.16.5.254

 

2.修改DNS

sudo vi /etc/systemd/resolved.conf

取消"dns"一行的注释,并添加需要的dns地址即可
