配置自定义VLAN网络（SUSE Linux Enterprise Server 12系列）

自定义VLAN网络网段信息不能与现有的裸金属服务器上已经配置的网络信息重叠。

下面以SUSE Linux Enterprise Server 12 SP1 (x86_64)操作系统为例，举例介绍裸金属服务器的自定义VLAN网络配置方法：

  1. 以“root”用户，使用密钥或密码登录裸金属服务器。
  2. 进入裸金属服务器的命令行界面，查询网卡信息。

    ip link

    返回信息示例如下：

    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 38:4c:4f:89:55:8d brd ff:ff:ff:ff:ff:ff
5: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 38:4c:4f:89:55:8e brd ff:ff:ff:ff:ff:ff
6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP mode DEFAULT group default 
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
7: bond0.3133@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP mode DEFAULT group default 
    link/ether fa:16:3e:57:87:6e brd ff:ff:ff:ff:ff:ff

    其中，“eth0”和“eth1”为承载VPC网络的网络设备，“eth2”和“eth3”为承载自定义VLAN网络的网络设备。

  3. 设置udev规则。

    执行以下命令创建“80-persistent-net.rules”文件。

    cp /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/80-persistent-net.rules

    将2中查询到的，且“80-persistent-net.rules”中未体现的网卡MAC地址和名称，写入该文件中，使得裸金属服务器重启复位后，网卡名称和顺序不会发生改变。

    网卡的MAC地址和名称中的字母，请使用小写字母。

    vim /etc/udev/rules.d/80-persistent-net.rules

    修改后的示例如下：

    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="38:4c:4f:29:0b:e0", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="38:4c:4f:29:0b:e1", NAME="eth1"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="38:4c:4f:89:55:8d", NAME="eth2"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="38:4c:4f:89:55:8e", NAME="eth3"

    修改完成后，保存并退出。

  4. 查询网卡的IP信息。

    ifconfig

    返回信息示例如下，其中的“bond0”和“bond0.313”为申请裸金属服务器时自动分配的网卡平面IP地址。

    bond0     Link encap:Ethernet  HWaddr FA:16:3E:3D:1C:E0  
          inet addr:10.0.1.2  Bcast:10.0.1.255  Mask:255.255.255.0

          collisions:0 txqueuelen:0 
          RX bytes:520 (520.0 b)  TX bytes:520 (520.0 b)

  5. 查询组成bond的网卡的名称。

    已组成bond且在使用中的网卡，不能用于内部通信平面，因此需要查询相应的网卡名称。

    cd /etc/sysconfig/network

    vi ifcfg-bond0

    返回信息示例如下，可见“bond0”由“eth0”和“eth1”组成。

    BONDING_MASTER=yes
TYPE=Bond
STARTMODE=auto
BONDING_MODULE_OPTS="mode=4 xmit_hash_policy=layer3+4 miimon=100"
NM_CONTROLLED=no
BOOTPROTO=dhcp
DEVICE=bond0
USERCONTRL=no
LLADDR=fa:16:3e:3d:1c:e0
BONDING_SLAVE1=eth1
BONDING_SLAVE0=eth0

    查询完成后，退出。

  6. 查询所有网卡的状态。

    ip link

    返回信息示例如下：

    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 38:4c:4f:89:55:8d brd ff:ff:ff:ff:ff:ff
5: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
    link/ether 38:4c:4f:89:55:8e brd ff:ff:ff:ff:ff:ff
6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP mode DEFAULT group default 
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
7: bond0.3133@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP mode DEFAULT group default 
    link/ether fa:16:3e:57:87:6e brd ff:ff:ff:ff:ff:ff

  7. 将所有状态为“qdisc mq state DOWN”的网卡，设置为“qdisc mq state UP”，示例中为“eth2”和“eth3”。

    ip link set eth2 up

    ip link set eth3 up

  8. 重新查询网卡的状态。

    ip link

    返回信息示例如下：

    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP mode DEFAULT group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 38:4c:4f:89:55:8d brd ff:ff:ff:ff:ff:ff
5: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 38:4c:4f:89:55:8e brd ff:ff:ff:ff:ff:ff
6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP mode DEFAULT group default 
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
7: bond0.3133@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP mode DEFAULT group default 
    link/ether fa:16:3e:57:87:6e brd ff:ff:ff:ff:ff:ff

  9. 查看8中对应的网卡的状态，获取状态为“qdisc mq state UP”的网卡名称。

    只有状态为“qdisc mq state UP”且未被使用过的网卡，才能组成bond，示例中为“eth2”和“eth3”。

    “eth2”的LLADR为“38:4c:4f:89:55:8d”，“eth3”的LLADR为“38:4c:4f:89:55:8e”。

  10. 创建“eth2”和“eth3”网卡的配置文件。

    可通过复制已有网卡配置文件的方式快速创建。

    cp ifcfg-eth0 ifcfg-eth2

    cp ifcfg-eth1 ifcfg-eth3

  11. 修改“eth2”和“eth3”网卡的配置文件。

    vi ifcfg-eth2

    vi ifcfg-eth3

    “eth2”网卡配置文件的修改示例如下。

    其中，参数参数“MTU”配置为“8888”,，“BOOTPROTO”需要配置为“STATIC”，参数“DEVICE”、“LLADDR”根据实际需要填写。

    STARTMODE=auto
MTU=8888
NM_CONTROLLED=no
BOOTPROTO=STATIC
DEVICE=eth2
USERCONTRL=no
LLADDR=38:4c:4f:89:55:8d
TYPE=Ethernet

    “eth3”网卡配置文件的修改示例如下：

    STARTMODE=auto
MTU=8888
NM_CONTROLLED=no
BOOTPROTO=STATIC
DEVICE=eth3
USERCONTRL=no
LLADDR=38:4c:4f:89:55:8e
TYPE=Ethernet

    修改完成后，保存并退出。

  12. 将“eth2”和“eth3”组bond，假设为“bond1”。

    创建ifcfg-bond1文件并修改配置。

    cp ifcfg-bond0 ifcfg-bond1

    vi ifcfg-bond1

    “bond1”网卡配置文件的修改示例如下。

    其中，参数“MTU”配置为“8888”，“BONDING_MODULE_OPTS”配置为“mode=1 miimon=100”，“BOOTPROTO”需要配置为“STATIC”，“DEVICE”、“BONDING_SLAVE1”、“BONDING_SLAVE0”、“IPADDR”、“NETMASK”、“NETWORK”根据实际需要填写，“LLADDR”配置为参数“BONDING_SLAVE1”对应网卡的LLADDR。

    BONDING_MASTER=yes
TYPE=Bond
MTU=8888
STARTMODE=auto
BONDING_MODULE_OPTS="mode=1 miimon=100"
NM_CONTROLLED=no
BOOTPROTO=STATIC
DEVICE=bond1
USERCONTRL=no
LLADDR=38:4c:4f:89:55:8d
BONDING_SLAVE1=eth2
BONDING_SLAVE0=eth3
IPADDR=10.0.2.2
NETMASK=255.255.255.0
NETWORK=10.0.2.0

    修改完成后，保存并退出。

  13. 使配置文件生效。

    1. 创建临时目录，并将网络配置文件复制到该目录下。

      mkdir /opt/tmp/

      mkdir /opt/tmp/xml

      cp /etc/sysconfig/network/ifcfg* /opt/tmp/

      cp /etc/sysconfig/network/config /opt/tmp/

      cp /etc/sysconfig/network/dhcp /opt/tmp/

    2. 停止待组成bond1的网卡。

      ip link set eth2 down

      ip link set eth3 down

    3. 将网卡配置文件转换成操作系统可辨识的配置文件。

      /usr/sbin/wicked --log-target=stderr --log-level=debug3 --debug all convert --output /opt/tmp/xml /opt/tmp/

    4. 重新启用待组成bond1的网卡。

      ip link set eth2 up

      /usr/sbin/wicked --log-target=stderr --log-level=debug3 --debug all ifup --ifconfig /opt/tmp/xml/eth2.xml eth2

      ip link set eth3 up

      /usr/sbin/wicked --log-target=stderr --log-level=debug3 --debug all ifup --ifconfig /opt/tmp/xml/eth3.xml eth3

      /usr/sbin/wicked --log-target=stderr --log-level=debug3 --debug all ifup --ifconfig /opt/tmp/xml/bond1.xml bond1

  14. 重新查询IP地址信息，可查看到IP地址已分配。

    ip addr show

    示例如下：

    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
3: eth1: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond0 state UP group default qlen 1000
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff

    link/ether 38:4c:4f:89:55:8d brd ff:ff:ff:ff:ff:ff
5: eth3: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 8888 qdisc mq master bond1 state UP group default qlen 1000
    link/ether 38:4c:4f:89:55:8d brd ff:ff:ff:ff:ff:ff
6: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP group default 
    link/ether fa:16:3e:3d:1c:e0 brd ff:ff:ff:ff:ff:ff
    inet 10.0.1.2/24 brd 10.0.1.255 scope global bond0
       valid_lft forever preferred_lft forever
    inet6 fe80::f816:3eff:fe3d:1ce0/64 scope link 
       valid_lft forever preferred_lft forever
7: bond0.3133@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP group default 
    link/ether fa:16:3e:57:87:6e brd ff:ff:ff:ff:ff:ff
    inet 10.0.3.2/24 brd 10.0.2.255 scope global bond0.3133
       valid_lft forever preferred_lft forever
    inet6 fe80::f816:3eff:fe57:876e/64 scope link 
       valid_lft forever preferred_lft forever
8: bond1: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 8888 qdisc noqueue state UP group default 
    link/ether 38:4c:4f:89:55:8d brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.2/24 brd 10.0.2.255 scope global bond1
       valid_lft forever preferred_lft forever
    inet6 fe80::3a4c:4fff:fe29:b36/64 scope link 
       valid_lft forever preferred_lft forever

  15. 删除创建的临时目录。

    cd /opt

    rm -rf tmp/

  16. 参考上述步骤，完成其他裸金属服务器上的配置。
