Abstract

The invention provides a method for binding network card names with equipment under Linux system, which comprises the following steps of: 1) viewing and recording the identification (ID) number of each network card and practical network card positions through Linux commands, i.e. lspci-v commands, 2) removing the part the mac address binding in network card configuration scripts; and 3) modifying files/etc/udev/rules.d/60-net.rules, and adding network card ID and relationships between corresponding network card drivers and network card names, wherein configuration commands are as follows: DRIVER=='igb', ID=='0000:05:00.0', NAME='eth0'DRIVER=='igb', ID=='0000:05:00.1', NAME='eth1'DRIVER=='e1000e', ID=='0000:03:00.0', NAME='eth2'.

Description

The method of network interface card title and apparatus bound under a kind of linux system

Technical field

The present invention relates to computer or network technology problem, specifically a kind of under the linux system binding method of many network interface cards configuration network interface card titles and physical device.

Background technology

Present many network interface cards machine is the general acquiescence network interface card configuration script that uses under the linux system, and especially when two network interface cards used different driver modules, there was following problem in this mode:

1) network interface card reversed, such as before the network interface that connects of your netting twine be eth0, after the driving that certain network interface card is installed, possible its name becomes eth0 or eth3, or the like situation;

2) the network interface card name changes, and can not find such as eth0, and many individual network interface cards are named as

__tmp3183921382193__；

3) light mouth network interface card is random with electricity mouthful network interface card order, perhaps intersects;

4) a certain network interface card fault causes the title drift in order of other network interface cards, the indivedual application relevant with the network interface card order of influence;

When the machine backup and reduction was disposed in batches, because network interface card mac address is inconsistent, the machine of every reduction all need remodify the network interface card configuration script, revised the mac address, was not suitable for carrying out large scale system and disposed.

Summary of the invention

The method that the purpose of this invention is to provide network interface card title and apparatus bound under a kind of linux system.

The objective of the invention is to realize by following mode, check through linux instruction lspci-v instruction id number of every network interface card with actual network interface card position, the line item of going forward side by side.

1) removes the part of mac address binding in the network interface card configuration script;

2) revised file/etc/udev/rules.d/60-net.rules, add network interface card id, corresponding network interface card drives and and the corresponding relation of network interface card title, order as follows:

DRIVER=="igb",ID=="0000:05:00.0",NAME="eth0"

DRIVER=="igb",ID=="0000:05:00.1",NAME="eth1"

DRIVER=="e1000e",ID=="0000:03:00.0",NAME="eth2"

The invention has the beneficial effects as follows: through the method that network interface card title and device id are bound, avoid network interface card to drift about in proper order and drive loading unusual problem, compare that present many network interface cards are general to be used and binding method has:

When 1) avoiding under the linux system configuration of many network interface cards, occur at random the network interface card number sequence change cause giving drive incorrect, the problem that network interface card is obstructed;

2) prevent a certain network interface card fault, network interface card drifts about in proper order, causes indivedual application relevant with the network interface card order to be interrupted;

3) need not pass through the mac address binding, avoid every the advantage such as problem that all will remodify network interface card configuration script mac address of machine after batch system reduces, thereby, have good value for applications.

Embodiment

Embodiment:

Three network interface cards of machines configurations, two intel 82574l are integrated on the mainboard, an intel 82572EI extrapolation; It is igb that integrated network card uses the driver module title; It is e1000e that the extrapolation network interface card uses driver module, system's installation and add the network interface card driver module after, do following configuration:

1) checks and confirms the device id of three network interface cards

[rootlocalhost?~]#?lspci?-v|grep?Ethernet

03:00.0?Ethernet?controller:?Intel?Corporation?82572EI?Gigabit?Ethernet?Controller?(Copper)?(rev?06)

05:00.0?Ethernet?controller:?Intel?Corporation?82574L?Gigabit?Ethernet?Controller?(Copper)?(rev?01)

05:00.1?Ethernet?controller:?Intel?Corporation?82574L?Gigabit?Ethernet?Controller?(Copper)?(rev?01)

2) revise three network interface card configuration scripts, the part of mac address binding is removed, the configuration script of following network interface card 0

[rootlocalhost?~]#?cat?/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

ONBOOT=yes

BOOTPROTO=dhcp

TYPE=Ethernet

3) modification/etc/udev/rules.d/60-net.rules file; Add the corresponding relation of network interface card driver module, network card equipment ID and network interface card title; Like this mainboard integrated network card is bound network interface card 0 and network interface card 1; With the extrapolation network card binding is network interface card 2, even if there are indivedual network interface card damage also can not cause the order of network interface card title to change.

ACTION=="add",?SUBSYSTEM=="net",?IMPORT{program}="/lib/udev/rename_device"

SUBSYSTEM=="net",?RUN+="/etc/sysconfig/network-scripts/net.hotplug"

DRIVER=="igb",ID=="0000:05:00.0",NAME="eth0"

DRIVER=="igb",ID=="0000:05:00.1",NAME="eth1"

DRIVER=="e1000e",ID=="0000:03:00.0",NAME="eth2"

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.

Claims

1. the method for network interface card title and apparatus bound under the linux system is characterized in that step is following:

1) checks id number and actual network interface card position of every network interface card, the line item of going forward side by side through linux instruction lspci-v instruction;

2) remove the part of mac address binding in the network interface card configuration script;

3) revised file/etc/udev/rules.d/60-net.rules, add network interface card id, corresponding network interface card drives and and the corresponding relation of network interface card title, configuration order is following:

DRIVER=="igb",ID=="0000:05:00.0",NAME="eth0"

DRIVER=="igb",ID=="0000:05:00.1",NAME="eth1"

DRIVER=="e1000e",ID=="0000:03:00.0",NAME="eth2"。
