    Netplan —— 抽象网络配置生成器 ,是一个用于配置 Linux 网络的简单工具。 通过 Netplan ,你只需用一个 YAML 文件描述每个网络接口需要配置成啥样即可。 根据这个配置描述, Netplan 便可帮你生成所有需要的配置,不管你选用的底层管理工具是啥。

    工作原理

    Netplan 从 /etc/netplan/*.yaml 读取配置,配置可以是管理员或者系统安装人员配置; 也可以是云镜像或者其他操作系统部署设施自动生成。 在系统启动阶段早期, Netplan 在 /run 目录生成好配置文件并将设备控制权交给相关后台程序。
    Netplan 工作原理

    Netplan 目前支持以下两种 网络管理工具 :

    NetworkManager
    Systemd-networkd
    一言以蔽之,从前你需要根据不同的管理工具编写网络配置,现在 Netplan 将管理工具差异性给屏蔽了。 你只需按照 Netplan 规范编写 YAML 配置,不管底层管理工具是啥,一份配置走天下!

    使用指引

    配置

    很显然,没有配置, Netplan 啥都做不了。 最简单有用的配置片段如下:

    network:
        version: 2
        renderer: NetworkManager
    

    这个配置让 NetworkManager 管理所有网络设备 (默认,只要检测到以太网设备接线,便以 DHCP 模式启动该设备)。

    使用 Systemd-networkd ,则不会自动启动网络设备; 每个需要启用的网卡均需要在 /etc/netplan 配置文件中指定配置。 网络配置示例如下:

    network:
        ethernets:
            enp0s3:
                addresses: []
                dhcp4: true
                optional: true
            enp0s8:
                addresses: [192.168.56.3/24]
                dhcp4: no
                optional: true
        version: 2
    

    这个配置为 enp0s3 网卡开启 DHCP 自动获取地址; 为 enp0s8 网卡配置了一个静态 IP 192.168.56.3 ,掩码是 24 位。

    命令

    netplan 操作命令提供两个子命令:

    netplan generate :以 /etc/netplan 配置为管理工具生成配置;
    netplan apply :应用配置(以便生效),必要时重启管理工具;

    因此,调整 /etc/netplan 配置后,需要执行以下命令方能生效:

    $ netplan apply
    

    配置示例

    DHCP
    network:
        ethernets:
            enp0s3:
                addresses: []
                dhcp4: true
        version: 2
    
    静态配置
    network:
        ethernets:
            enp0s8:
                addresses: [10.0.0.2/24]
                gateway4: 10.0.0.1
                nameservers:
                    addresses: [8.8.8.8,8.8.4.4]
                dhcp4: no
        version: 2

    Below are a collection of example netplan configurations for common scenarios. If you see a scenario missing or have one to contribute, please file a bug against this documentation with the example using the links at the bottom of this page. Thank you!


    Configuration

    To configure netplan, save configuration files under /etc/netplan/ with a .yaml extension (e.g. /etc/netplan/config.yaml), then run sudo netplan apply. This command parses and applies the configuration to the system. Configuration written to disk under /etc/netplan/ will persist between reboots.

    Using DHCP and static addressing

    To let the interface named ‘enp3s0’ get an address via DHCP, create a YAML file with the following:

    network:
        version: 2
        renderer: networkd
        ethernets:
            enp3s0:
                dhcp4: true
    

    To instead set a static IP address, use the addresses key, which takes a list of (IPv4 or IPv6), addresses along with the subnet prefix length (e.g. /24). Gateway and DNS information can be provided as well:

    network:
        version: 2
        renderer: networkd
        ethernets:
            enp3s0:
                addresses:
                    - 10.10.10.2/24
                gateway4: 10.10.10.1
                nameservers:
                    search: [mydomain, otherdomain]
                    addresses: [10.10.10.1, 1.1.1.1]
    

    Connecting multiple interfaces with DHCP

    Many systems now include more than one network interface. Servers will commonly need to connect to multiple networks, and may require that traffic to the Internet goes through a specific interface despite all of them providing a valid gateway.

    One can achieve the exact routing desired over DHCP by specifying a metric for the routes retrieved over DHCP, which will ensure some routes are preferred over others. In this example, ‘enred’ is preferred over ‘engreen’, as it has a lower route metric:

    network:
        version: 2
        ethernets:
            enred:
                dhcp4: yes
                dhcp4-overrides:
                    route-metric: 100
            engreen:
                dhcp4: yes
                dhcp4-overrides:
                    route-metric: 200
    

    Connecting to an open wireless network

    Netplan easily supports connecting to an open wireless network (one that is not secured by a password), only requiring that the access point is defined:

    network:
        version: 2
        wifis:
            wl0:
                access-points:
                    opennetwork: {}
                dhcp4: yes
    

    Connecting to a WPA Personal wireless network

    Wireless devices use the ‘wifis’ key and share the same configuration options with wired ethernet devices. The wireless access point name and password should also be specified:

    network:
        version: 2
        renderer: networkd
        wifis:
            wlp2s0b1:
                dhcp4: no
                dhcp6: no
                addresses: [192.168.0.21/24]
                gateway4: 192.168.0.1
                nameservers:
                    addresses: [192.168.0.1, 8.8.8.8]
                access-points:
                    "network_ssid_name":
                        password: "**********"
    

    Connecting to WPA Enterprise wireless networks

    It is also common to find wireless networks secured using WPA or WPA2 Enterprise, which requires additional authentication parameters.

    For example, if the network is secured using WPA-EAP and TTLS:

    network:
        version: 2
        wifis:
            wl0:
                access-points:
                    workplace:
                        auth:
                            key-management: eap
                            method: ttls
                            anonymous-identity: "@internal.example.com"
                            identity: "joe@internal.example.com"
                            password: "v3ryS3kr1t"
                dhcp4: yes
    

    Or, if the network is secured using WPA-EAP and TLS:

    network:
        version: 2
        wifis:
            wl0:
                access-points:
                    university:
                        auth:
                            key-management: eap
                            method: tls
                            anonymous-identity: "@cust.example.com"
                            identity: "cert-joe@cust.example.com"
                            ca-certificate: /etc/ssl/cust-cacrt.pem
                            client-certificate: /etc/ssl/cust-crt.pem
                            client-key: /etc/ssl/cust-key.pem
                            client-key-password: "d3cryptPr1v4t3K3y"
                dhcp4: yes
    

    Many different modes of encryption are supported. See the Netplan reference page.

    Using multiple addresses on a single interface

    The addresses key can take a list of addresses to assign to an interface:

    network:
        version: 2
        renderer: networkd
        ethernets:
            enp3s0:
             addresses:
                 - 10.100.1.38/24
                 - 10.100.1.39/24
             gateway4: 10.100.1.1
    

    Interface aliases (e.g. eth0:0) are not supported.

    Using multiple addresses with multiple gateways

    Similar to the example above, interfaces with multiple addresses can be
    configured with multiple gateways.

    network:
        version: 2
        renderer: networkd
        ethernets:
            enp3s0:
             addresses:
                 - 9.0.0.9/24
                 - 10.0.0.10/24
                 - 11.0.0.11/24
             #gateway4:  # unset, since we configure routes below
             routes:
                 - to: 0.0.0.0/0
                     via: 9.0.0.1
                     metric: 100
                 - to: 0.0.0.0/0
                     via: 10.0.0.1
                     metric: 100
                 - to: 0.0.0.0/0
                     via: 11.0.0.1
                     metric: 100
    

    Given that there are multiple addresses, each with their own gateway, we do not specify gateway4 here, and instead configure
    individual routes to 0.0.0.0/0 (everywhere) using the address of the gateway for the subnet. The metric value should be adjusted
    so the routing happens as expected.

    DHCP can be used to receive one of the IP addresses for the interface. In this case, the default route for that address will be
    automatically configured with a metric value of 100. As a short-hand for an entry under routes, gateway4 can be set to the
    gateway address for one of the subnets. In that case, the route for that subnet can be omitted from routes. Its metric will be
    set to 100.

    Using Network Manager as a renderer

    Netplan supports both networkd and Network Manager as backends. You can specify which network backend should be used to configure particular devices by using the renderer key. You can also delegate all configuration of the network to Network Manager itself by specifying only the renderer key:

    network:
        version: 2
        renderer: NetworkManager
    

    then you could use nmtui or nmcli to manage network. The Command apt install network-manager will install the NetworkManager.

    Configuring interface bonding

    Bonding is configured by declaring a bond interface with a list of physical interfaces and a bonding mode. Below is an example of an active-backup bond that uses DHCP to obtain an address:

    network:
        version: 2
        renderer: networkd
        bonds:
            bond0:
                dhcp4: yes
                interfaces:
                    - enp3s0
                    - enp4s0
                parameters:
                    mode: active-backup
                    primary: enp3s0
    

    Below is an example of a system acting as a router with various bonded interfaces and different types. Note the ‘optional: true’ key declarations that allow booting to occur without waiting for those interfaces to activate fully.

    network:
        version: 2
        renderer: networkd
        ethernets:
            enp1s0:
                dhcp4: no
            enp2s0:
                dhcp4: no
            enp3s0:
                dhcp4: no
                optional: true
            enp4s0:
                dhcp4: no
                optional: true
            enp5s0:
                dhcp4: no
                optional: true
            enp6s0:
                dhcp4: no
                optional: true
        bonds:
            bond-lan:
                interfaces: [enp2s0, enp3s0]
                addresses: [192.168.93.2/24]
                parameters:
                    mode: 802.3ad
                    mii-monitor-interval: 1
            bond-wan:
                interfaces: [enp1s0, enp4s0]
                addresses: [192.168.1.252/24]
                gateway4: 192.168.1.1
                nameservers:
                    search: [local]
                    addresses: [8.8.8.8, 8.8.4.4]
                parameters:
                    mode: active-backup
                    mii-monitor-interval: 1
                    gratuitious-arp: 5
            bond-conntrack:
                interfaces: [enp5s0, enp6s0]
                addresses: [192.168.254.2/24]
                parameters:
                    mode: balance-rr
                    mii-monitor-interval: 1
    

    Configuring network bridges

    To create a very simple bridge consisting of a single device that uses DHCP, write:

    network:
        version: 2
        renderer: networkd
        ethernets:
            enp3s0:
                dhcp4: no
        bridges:
            br0:
                dhcp4: yes
                interfaces:
                    - enp3s0
    

    A more complex example, to get libvirtd to use a specific bridge with a tagged vlan, while continuing to provide an untagged interface as well would involve:

    network:
        version: 2
        renderer: networkd
        ethernets:
            enp0s25:
                dhcp4: true
        bridges:
            br0:
                addresses: [ 10.3.99.25/24 ]
                interfaces: [ vlan15 ]
        vlans:
            vlan15:
                accept-ra: no
                id: 15
                link: enp0s25
    

    Then libvirtd would be configured to use this bridge by adding the following content to a new XML file under /etc/libvirtd/qemu/networks/. The name of the bridge in the tag as well as in need to match the name of the bridge device configured using netplan:

    <network>
        <name>br0</name>
        <bridge name='br0'/>
        <forward mode="bridge"/>
    </network>
    

    Attaching VLANs to network interfaces

    To configure multiple VLANs with renamed interfaces:

    network:
        version: 2
        renderer: networkd
        ethernets:
            mainif:
                match:
                    macaddress: "de:ad:be:ef:ca:fe"
                set-name: mainif
                addresses: [ "10.3.0.5/23" ]
                gateway4: 10.3.0.1
                nameservers:
                    addresses: [ "8.8.8.8", "8.8.4.4" ]
                    search: [ example.com ]
        vlans:
            vlan15:
                id: 15
                link: mainif
                addresses: [ "10.3.99.5/24" ]
            vlan10:
                id: 10
                link: mainif
                addresses: [ "10.3.98.5/24" ]
                nameservers:
                    addresses: [ "127.0.0.1" ]
                    search: [ domain1.example.com, domain2.example.com ]
    

    Reaching a directly connected gateway

    This allows setting up a default route, or any route, using the “on-link” keyword where the gateway is an IP address that is directly connected to the network even if the address does not match the subnet configured on the interface.

    network:
        version: 2
        renderer: networkd
        ethernets:
            addresses: [ "10.10.10.1/24" ]
            routes:
                - to: 0.0.0.0/0
                    via: 9.9.9.9
                    on-link: true
    

    For IPv6 the config would be very similar, with the notable difference being an additional scope: link host route to the router’s address required:

    network:
        version: 2
        renderer: networkd
        ethernets:
            addresses: [ "2001:cafe:face:beef::dead:dead/64" ]
            routes:
                - to: "2001:cafe:face::1/128"
                    scope: link
                - to: "::/0"
                    via: "2001:cafe:face::1"
                    on-link: true
    

    Configuring source routing

    Route tables can be added to particular interfaces to allow routing between two networks:

    In the example below, ens3 is on the 192.168.3.0/24 network and ens5 is on the 192.168.5.0/24 network. This enables clients on either network to connect to the other and allow the response to come from the correct interface.

    Furthermore, the default route is still assigned to ens5 allowing any other traffic to go through it.

    network:
        version: 2
        renderer: networkd

                    table: 102
    

    Configuring a loopback interface

    Networkd does not allow creating new loopback devices, but a user can add new addresses to the standard loopback interface, lo, in order to have it considered a valid address on the machine as well as for custom routing:

    network:
        version: 2
        renderer: networkd
        ethernets:
            lo:
                match:
                    name: lo
                addresses: [ 7.7.7.7/32 ]
    

    Integration with a Windows DHCP Server

    For networks where DHCP is provided by a Windows Server using the dhcp-identifier key allows for interoperability:

    network:
        version: 2
        ethernets:
            enp3s0:
                dhcp4: yes
                dhcp-identifier: mac
    

    Connecting an IP tunnel

    Tunnels allow an administrator to extend networks across the Internet by configuring two endpoints that will connect a special tunnel interface and do the routing required. Netplan supports SIT, GRE, IP-in-IP (ipip, ipip6, ip6ip6), IP6GRE, VTI and VTI6 tunnels.

    A common use of tunnels is to enable IPv6 connectivity on networks that only support IPv4. The example below show how such a tunnel might be configured.

    Here, 1.1.1.1 is the client’s own IP address; 2.2.2.2 is the remote server’s IPv4 address, “2001:dead:beef::2/64” is the client’s IPv6 address as defined by the tunnel, and “2001:dead:beef::1” is the remote server’s IPv6 address.

    Finally, “2001:cafe:face::1/64” is an address for the client within the routed IPv6 prefix:

    network:
        version: 2
        ethernets:
            eth0:
                addresses:
                    - 1.1.1.1/24
                    - "2001:cafe:face::1/64"
                gateway4: 1.1.1.254
        tunnels:
            he-ipv6:
                mode: sit
                remote: 2.2.2.2
                local: 1.1.1.1
                addresses:
                    - "2001:dead:beef::2/64"
                gateway6: "2001:dead:beef::1"
    

    Configuring SR-IOV Virtual Functions

    For SR-IOV network cards, it is possible to dynamically allocate Virtual Function interfaces for every configured Physical Function. In netplan, a VF is defined by having a link: property pointing to the parent PF.

    network:
        version: 2
        ethernets:
            eno1:
                mtu: 9000
            enp1s16f1:
                link: eno1
                addresses : [ "10.15.98.25/24" ]
            vf1:
                match:
                    name: enp1s16f[2-3]
                link: eno1
                addresses : [ "10.15.99.25/24" ]

    Ubuntu 通过 Netplan 配置网络教程

    Ubuntu through Netplan configuration network tutorial

    374a17c33da5cb938931d3a3900a66f1.png

    一、Netplan 配置流程

    1. Netplan configuration process

    1、Netplan默认配置文件在/etc/netplan目录下。您可以使用以下命令找到:

    1. The default configuration file of Netplan is in the /etc/netplan directory. You can find it with the following command:

    ls /etc/netplan/

    就可以看到配置文件名称。

    You can see the configuration file name.

    2、查看Netplan网络配置文件的内容,执行以下命令:

    2. View the contents of the Netplan network configuration file and execute the following command:

    cat /etc/netplan/*.yaml

    3、现在你需要在任何编辑器中打开配置文件: 由于我使用 vim 编辑器来编辑配置文件,所以我将运行:

    3. Now you need to open the configuration file in any editor: Since I use the vim editor to edit the configuration file, I will run:

    vim /etc/netplan/*.yaml

    根据您的网络需要更新配置文件。对于静态 IP 寻址,添加 IP 地址、网关、DNS 信息,而对于动态 IP 寻址,无需添加此信息,因为它将从 DHCP 服务器获取此信息。使用以下语法编辑配置文件。

    Update the configuration file according to your network needs. For static IP addressing, add IP address, gateway, DNS information, and for dynamic IP addressing, there is no need to add this information because it will get this information from the DHCP server. Use the following syntax to edit the configuration file.

    4、在应用任何更改之前,我们将测试配置文件。

    4. We will test the configuration file before applying any changes.

    sudo netplan try

    如果没有问题,它将返回配置接受消息。如果配置文件未通过测试,它将恢复为以前的工作配置。

    If there is no problem, it will return a configuration acceptance message. If the configuration file fails the test, it will revert to the previous working configuration.

    5、运行以下命令来应用新配置:

    5. Run the following command to apply the new configuration:

    sudo netplan apply

    6、成功应用所有配置后,通过运行以下命令重新启动 Network-Manager 服务:

    6. After successfully applying all the configurations, restart the Network-Manager service by running the following command:

    如果是桌面版:

    If it is the desktop version:

    sudo systemctl restart system-networkd

    如果您使用的是 Ubuntu 服务器,请改用以下命令:

    If you are using an Ubuntu server, use the following command instead:

    sudo systemctl restart network-manager

    7、验证 IP 地址

    7. Verify the IP address

    ip a

    二、Netplan 配置文件详解

    2. Detailed explanation of Netplan configuration file   

    1、使用 DHCP:

    1. Use DHCP:

    network:
      version: 2
      renderer: networkd
      ethernets:
        enp3s0:
          dhcp4: true

    2、使用静态 IP:

    2. Use static IP:

    network:
      version: 2
      renderer: networkd
      ethernets:
        enp3s0:
          addresses:
            - 10.0.0.10/8
          gateway4: 10.0.0.1
          nameservers:
              search: [mydomain, otherdomain]
              addresses: [10.0.0.5, 1.1.1.1]

    3、多个网口 DHCP:

    3. Multiple network ports DHCP:

    network:
      version: 2
      ethernets:
        enred:
          dhcp4: yes
          dhcp4-overrides:
            route-metric: 100
        engreen:
          dhcp4: yes
          dhcp4-overrides:
            route-metric: 200

    4、连接开放的 WiFi(无密码):

    4. Connect to open WiFi (without password):

    network:
      version: 2
      wifis:
        wl0:
          access-points:
            opennetwork: {}
          dhcp4: yes

    5、连接 WPA 加密的 WiFi:

    5. Connect to WPA encrypted WiFi:

    network:
      version: 2
      renderer: networkd
      wifis:
        wlp2s0b1:
          dhcp4: no
          dhcp6: no
          addresses: [10.0.0.10/8]
          gateway4: 10.0.0.1
          nameservers:
            addresses: [10.0.0.5, 8.8.8.8]
          access-points:
            "network_ssid_name":
              password: "**********"

    6、在单网卡上使用多个 IP 地址(同一网段):

    6. Use multiple IP addresses on a single network card (same network segment):

    network:
      version: 2
      renderer: networkd
      ethernets:
        enp3s0:
         addresses:
           - 10.0.0.10/8
           - 10.0.0.10/8
         gateway4: 10.0.0.1

    7、在单网卡使用多个不同网段的 IP 地址:

    7. Use multiple IP addresses of different network segments on a single network card:

    network:
      version: 2
      renderer: networkd
      ethernets:
        enp3s0:
         addresses:
           - 9.0.0.9/24
           - 10.0.0.10/24
           - 11.0.0.11/24
         #gateway4:    # unset, since we configure routes below
         routes:
           - to: 0.0.0.0/0
             via: 9.0.0.1
             metric: 100
           - to: 0.0.0.0/0
             via: 10.0.0.1
             metric: 100
           - to: 0.0.0.0/0
             via: 11.0.0.1
             metric: 100
