从 ifupdown 迁移到 netplan

我尝试从 迁移ifupdown到netplan，但结果总是不一样。

netplan像这样的配置的正确配置是什么networking：

auto lo
iface lo inet loopback

auto eno0
iface eno0 inet static
  address xxx.xxx.51.20/24
  gateway xxx.xxx.51.254 
  post-up echo 1 > /proc/sys/net/ipv4/ip_forward
  post-up echo 1 > /proc/sys/net/ipv4/conf/eno0/proxy_arp


auto vmbr0
iface vmbr0 inet static
  address xxx.xxx.198.104/24
  bridge-ports none
  bridge-stp off
  bridge-fd 0


auto vmbr1
iface vmbr1 inet static
  address xxx.xxx.198.105/24
  bridge-ports none
  bridge-stp off
  bridge-fd 0

auto vmbr2
iface vmbr2 inet static
  address xxx.xxx.198.106/24
  bridge-ports none
  bridge-stp off
  bridge-fd 0

auto vmbr3
iface vmbr3 inet static
  address xxx.xxx.198.107/24
  bridge-ports none
  bridge-stp off
  bridge-fd 0

经过几天的反复试验，我发现目前 [netplan 尚不支持 macvlan bridge][5]，我们需要一种解决方法并改变systemd网络：

  • 我们需要在上创建一些文件/etc/systemd/network，因此导航到目录：
$ cd /etc/systemd/network
  • 定义网桥的vlan，请更改cat为您的编辑器
$ cat 00-vmvlan0.netdev 
[NetDev]
Name=vmvlan0
Kind=macvlan
# Optional MAC address, or other options
MACAddress=xx:xx:xx:xx:26:12

[MACVLAN]
Mode=bridge

$ cat 00-vmvlan0.network 
[Match]
Name=vmvlan0

[Network]
Address=xxx.xxx.198.104/32
IPForward=yes
ConfigureWithoutCarrier=yes
  • 定义桥梁
$ cat 00-vmbr0.netdev 
[NetDev]
Name=vmbr0
Kind=bridge

$ cat 00-vmbr0.network 
[Match]
Name=vmbr0

[Network]
MACVLAN=vmvlan0
  • 对下一个 IP 重复上述操作
  • 链接桥、vlan 和接口：
$ cat 10-netplan-eno1.link 
[Match]
MACAddress=xx:xx:xx:xx:19:d0

[Link]
Name=eno1
WakeOnLan=off

$ cat 10-netplan-eno1.network 
[Match]
MACAddress=xx:xx:xx:xx:19:d0
Name=eno1

[Network]
DHCP=ipv4
LinkLocalAddressing=ipv6
MACVLAN=vmvlan0
MACVLAN=vmvlan1
MACVLAN=vmvlan2
MACVLAN=vmvlan3

[DHCP]
RouteMetric=100
UseMTU=true
  • 我们可以使用默认的 netplan 配置：
$ sudo cat /etc/netplan/50-cloud-init.yaml
network:
    version: 2
    ethernets:
        eno1:
            dhcp4: true
            match:
                macaddress: xx:xx:xx:2a:19:d0
            set-name: eno1
