修改dns

network:
  ethernets:
    ens3:
      dhcp4-overrides:
        use-dns: false
      nameservers:
        addresses: 
          - 223.5.5.5
          - 223.6.6.6
  version: 2

cat > /etc/netplan/51-dns.yaml << EOF
network:
  ethernets:
    ens3:
      dhcp4-overrides:
        use-dns: false
      nameservers:
        addresses: 
          - 223.5.5.5
          - 223.6.6.6
  version: 2
EOF
netplan apply

修改网络接口名（危险，修改完会导致网络无法正确获取ip）

network:
  version: 2
  ethernets:
    ens3:
      set-name: "eth0"

cat > /etc/netplan/52-device-name.yaml << EOF
network:
  version: 2
  ethernets:
    ens3:
      set-name: "eth0"
EOF
netplan apply
