SUSE Linux Enterprise Server 12系列-物理机-用户指南-自定义VLAN网络配置

注意事项：

自定义VLAN网络网段不能与现有的物理机上已经配置的网段重叠。

下面以SUSE Linux Enterprise Server 12 SP1 (x86_64)操作系统为例，举例介绍物理机的自定义VLAN网络配置方法：

步骤 1 以“root”用户，使用密钥或密码登录物理机。

步骤 2 进入物理机的命令行界面，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


                    说明
                    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。

步骤 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

将步骤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，使得物理机重启复位后，网卡名称和顺序不会发生改变。


                    说明
                    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。

步骤 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”为申请物理机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
          inet6 addr: fe80::f816:3eff:fe3d:1ce0/64 Scope:Link

          RX bytes:125429 (122.4 Kb)  TX bytes:107221 (104.7 Kb)
 
bond0.313 Link encap:Ethernet  HWaddr FA:16:3E:57:87:6E  
          inet addr:10.0.3.2  Bcast:10.0.3.255  Mask:255.255.255.0
          inet6 addr: fe80::f816:3eff:fe57:876e/64 Scope:Link

          RX bytes:8684 (8.4 Kb)  TX bytes:1696 (1.6 Kb)
 
eth0      Link encap:Ethernet  HWaddr FA:16:3E:3D:1C:E0  
          UP BROADCAST RUNNING SLAVE MULTICAST  MTU:8888  Metric:1
          RX packets:428 errors:0 dropped:10 overruns:0 frame:0
          TX packets:547 errors:0 dropped:0 overruns:0 carrier:0

          TX packets:574 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:60759 (59.3 Kb)  TX bytes:57089 (55.7 Kb)

          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:8 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:520 (520.0 b)  TX bytes:520 (520.0 b)

步骤 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。

步骤 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

步骤 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

步骤 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

查看步骤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”。

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

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。

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。

使配置文件生效。
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/

停止待组成bond1的网卡。

ip link set eth2 down

ip link set eth3 down

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/

重新启用待组成bond1的网卡。

/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

重新查询IP地址信息，可查看到IP地址已分配。

       valid_lft forever preferred_lft forever

示例如下：

cd /opt

rm -rf tmp/

参考上述步骤，完成其他物理机上的配置。
