Ubuntu18.04設置固定IP

環境信息
系統：Ubuntu 18.04.01

在低版本的Ubuntu系統中，設置固定IP還是通過編輯**/etc/network/interface配置文件來實現的，但是高版本的Ubuntu系統後，再設置固定IP就得通過修改/etc/netplan/50-cloud-init.yaml**來實現了

1. 編輯文件，設置固定IPvim /etc/netplan/50-cloud-init.yaml

# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# 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:
        ens33:
            addresses: [192.168.94.20/24]
            gateway4: 192.168.94.2
            dhcp4: no
            nameservers:
               addresses: [114.114.114.114]
    version: 2
    renderer: networkd

2. 保存退出後，執行命令重啓netplan apply
