Ubuntu 18 LTS netplan 网络配置

今天装完 Ubuntu 18 LTS,配置网络时发现Ubuntu 18LTS ifupdown has been replaced by netplan(5) on this system。

随手记录一下netplan配置。

• vim /etc/network/interfaces 修改网络配置时发现Ubuntu 18LTS ifupdown has been replaced by netplan(5) on this system。

# ifupdown has been replaced by netplan(5) on this system.  See
# /etc/netplan for current configuration.
# To re-enable ifupdown on this system, you can run:
#    sudo apt install ifupdown

• 直接配置netplan吧

vim /etc/netplan/50-cloud-init.yaml 

配置如下：
network:
    ethernets:
        enp4s0:
            addresses: [192.168.0.20/24]  //IP址
            gateway4: 192.168.0.1  // 网关
            nameservers:
             addresses: [114.114.114.114, 192.168.0.1] //DNS
            dhcp4: no
            optional: no
    version: 2

• 启用生效

sudo netplan apply
