[Linux] Ubuntu 18 LTS netplan 網絡配置

Ubuntu 18 LTS netplan 網絡配置

今天裝完 Ubuntu 18 LTS,配置網絡時發現Ubuntu 18LTS ifupdown has been replaced by netplan(5) on this system。
隨手記錄一下netplan配置。

• vim /etc/network/interfaces 修改網絡配置時發現Ubuntu 18LTS ifupdown has been replaced by netplan(5) on this system。

# ifupdown has been replaced by netplan(5) on this system.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 

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

• 啓用生效

sudo netplan apply
