Abstract
The invention discloses an automatic implementation method for binding a network card to a CPU (central processing unit). the implementation method utilizes a shell script to automatically acquire a network port interrupt number according to a set network port name and a CPU serial number, and binds the interrupt number to a specified CPU according to set parameters. By adopting the technology provided by the invention, the full-automatic binding of the specific network card to the appointed CPU is realized through the shell script, only the network port name and the CPU serial number need to be manually input, other processes are completely and automatically completed, and a large amount of system commands and other operations do not need to be manually input. The script is convenient to use and simple to operate, and can be operated without mastering professional knowledge. The method is applied to the performance test stage of the server and is used for improving the network performance when the server is put into use, so that the labor and the time can be saved, and the working efficiency is improved.
Description
Technical field
The present invention relates to computer network field, be specifically related to a kind of by the robotization implementation method of network card binding to CPU.
Background technology
Server is exactly network with extraneous passage of coming into contacts with, and no matter server has carried out the work of which complexity, and its net result all will by network-feedback to request object.Say that network interface card is exactly " throat " parts of server correspondence with foreign country and contact in a sense, the performance of network interface card determines the overall performance of server to a certain extent.The Cloud Server of fast development especially now be unable to do without high performance network support especially.
Server is not all the time in the computing that process is a large amount of, so network interface card will affect response and the performance of network interface card when striving for cpu resource with other programs, if there is way that network interface card interrupt distribution is processed to specific core cpu, just better network performance can be obtained.Present server is substantially all multi-CPU, multi-core, so can as the method improving server network performance on CPU to specifying using network card binding.
But realize network interface card to need to input a large amount of system commands to specifying the binding between CPU, this not only needs skilled operation and professional knowledge, and server and network interface card more time also need a large amount of time.Therefore develop one based on shell script by the robotization implementation tool IRQ.sh of network card binding to CPU.
Shell script, Shell Script, similar to the batch processing under Windows/Dos, namely put in advance in a file with all kinds of order, facilitate a program file of disposable execution, mainly facilitate keeper to carry out arranging or manage.But the order under it using Linux/Unix, more powerful than the batch processing under Windows, the program efficiency of editor is higher.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of by the robotization implementation method of network card binding to CPU.
The technical solution adopted in the present invention is:
By the robotization implementation method of network card binding to CPU, described implementation method utilizes shell script according to the network interface title of setting and CPU sequence number, automatic acquisition network interface interrupt number, and according to set parameter, this interrupt number is tied to the CPU specified.
Described implementation method manually need only input network interface name and CPU sequence number, and other processes complete completely automatically.Realize ad hoc networks by shell script and snap into the full-automatic binding of specifying CPU, only need manually input network interface name and CPU sequence number, without the need to manually inputting a large amount of system commands and other operations.
Described method performing step is as follows:
1) network interface name and the CPU sequence number of manually input is read:
Run this automatic test script by command terminal, after manually inputting the network interface and No. CPU needing to carry out binding, shell script can read these two parameters also for binding is afterwards prepared, and points out the network interface and No. CPU that will bind to user simultaneously;
2) check whether irqbalance service opens:
After the network interface and CPU of manually input needs binding, just enter full automatic binding procedure.First whether script can be opened by detection system service irqbalance, binding result can be caused ineffective if hold service unlatching, close this service so can point out when detecting that this service is opened and then carry out bindings, if close, directly entering next step;
3) bindings is completed:
After the detection of the input and system service program that complete network interface and CPU parameter, it is the binding that network interface interrupts CPU that script starts to enter next step, first interrupt number corresponding to this network interface is obtained according to the network interface name of input, then automatic being tied to by interrupt number specifies CPU, and binding result is printed to screen display out, facilitate record.
Beneficial effect of the present invention: adopt technology provided by the present invention, realize ad hoc networks by shell script and snap into the full-automatic binding of specifying CPU, manually need only input network interface name and CPU sequence number, other processes complete completely automatically, without the need to manually inputting a large amount of system commands and other operations.This script is easy to use, simple to operate, also can complete operation without the need to grasping professional knowledge.The method is applied in when server performance test phase and server come into operation and is used for improving network performance, can save manpower and time, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is present system construction method figure.

Please input the Network port and the CPU:(inputs) eth0 CPU0
The Network port and the CPU are： eth0 CPU0
2) check whether irqbalance service opens:
After the network interface and CPU of manually input needs binding, just enter full automatic binding procedure.First whether script can be opened by detection system service irqbalance, binding result can be caused ineffective if hold service unlatching, close this service so can point out when detecting that this service is opened and then carry out bindings, if close, directly entering next step;
3) bindings is completed:
After the detection of the input and system service program that complete network interface and CPU parameter, it is the binding that network interface interrupts CPU that script starts to enter next step, first interrupt number corresponding to this network interface is obtained according to the network interface name of input, then automatic being tied to by interrupt number specifies CPU, and binding result is printed to screen display out, facilitate record.
