Abstract

The invention provides a rapid and unattended operation system, which comprises a head node and a plurality of child nodes, wherein the head node is connected with the child nodes through a switchboard; the head node is provided with a terminal service device; and each child node is provided with a server, and each server is provided with a network card which has a preboot execution environment read only memory (PXEROM) chip. In a limit range which can be born by the servers, an operating system can be installed in a plurality of servers simultaneously, so that the system is high in concentration degree, the installation speed is greatly increased, the phenomenon of different system configuration because the operating system is installed by different personnel is prevented, and the inconsistency of files is effectively prevented.

Description

A kind of quick, unattended operated system

Technical field

The present invention relates to a kind of quick, unattended operated system.

Background technology

Existingly generally adopt CD to install or install copying through hard disk to build-in services device system; Because the number of servers that produce every day is bigger; As use CD to install, need to prepare tens of operating systems, as with hard disk to copying; Speed and efficient are lower, and installation personnel is forgotten because of other thing or do not had mark installment to occur easily searching to that and causes inefficiency sometimes.

Summary of the invention

The objective of the invention is to overcome the deficiency that prior art exists, a kind of quick, unattended operated system is provided.

The object of the invention is realized through following technical scheme:

A kind of quick, unattended operated system; It is characterized in that: comprise a head node and a plurality of child node; Said head node is connected through switch with child node; Said head node is provided with the terminal service device, and said child node is provided with server, and server is provided with the network interface card of PXE rom chip.

Further, above-mentioned a kind of quick, unattended operated system, wherein, child node is provided with 3 servers at least, and all is connected with head node through switch.

The substantive distinguishing features of technical scheme of the present invention is mainly reflected in progressive:

The present invention in the limit range that server can carry, can multiple servers installing operating system simultaneously, intensity is high, is exceedingly fast and has quickened installation rate, and easy care, removes the loss of conventional optical disc from.Use simple, intuitive, only need select relative operation system to get final product up and down during operation; Be prone to customize, the configuration file of retouching operation system source file can come into force immediately at any time; The system configuration of avoiding different personnel's installations to cause is different, effectively prevents the inconsistency of file.

Description of drawings

Below in conjunction with accompanying drawing technical scheme of the present invention is described further:

Fig. 1: structural representation block diagram of the present invention.

Embodiment

A kind of fast, the unattended operated system (can expand by native system; Is example at this with a head node and three node); Comprise that head node 1, child node 3, child node 4 andchild node 5 connect to form throughswitch 2; As shown in Figure 1, wherein head node 1 is provided with the terminal service device, and head node 1 is equipped with the LINUX system of server version; Child node is provided with (comprising 3,4,5) network interface card of PXE rom chip, and child node is provided with 3 servers and all is connected with head node 1 through switch 2.Wherein, be provided with Dynamic Host Configuration Protocol server, tftp server in the terminal service device.

The deployment operation system starting process is following automatically for PXE (Preboot Execution Environment, Pre-boot Execution Environment):

A) the terminal service device starts, and the BIOS in its device is provided with network interface card and starts, and has program in the network interface card of PXE rom chip then and is called in internal memory and carry out;

B) client is sought the DHCP server in network, asks an IP address then;

C) the DHCP server is that client provides IP address and other network parameters;

D) Dynamic Host Configuration Protocol server is related to a TFTP server client transmission bootstrap (boot) for this reason;

E) client is received the execution of bootstrap (boot files pxelinux.0) back, and bootstrap can ask TFTP to transmit the configuration file (pxelinux.cfg/default) of bootstrap; Read configuration file after receiving, according to this configuration file content and client's situation, client-requested TFTP transmits kernel image file (vmlinuz) and system start-up file (initrd.img);

F) start kernel;

G) kernel obtains the automatic installation script of operating system according to the configuration file of bootstrap through network, and through the required installation file of network service (nfs/ftp/http) acquisition system, installs according to the configuration of automatic installation script.

In the limit range that server can carry, can be to multiple servers installing operating system simultaneously according to above-mentioned step, intensity is high, is exceedingly fast and has quickened installation rate, has improved operating efficiency.Its device uses simple, intuitive, only need select relative operation system to get final product up and down during operation, is prone to customize, and the configuration file of retouching operation system source file comes into force immediately at any time; Installing operating system only needs a people to accomplish, and the system configuration that can avoid different personnel's installations to cause is different, effectively prevents the file inconsistency.

It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.

Claims (2)

1. One kind fast, the unattended operated system; It is characterized in that: comprise a head node and a plurality of child node; Said head node is connected through switch with child node; Said head node is provided with the terminal service device, and said child node is provided with server, and server is provided with the network interface card of PXE rom chip.
2. 2. a kind of quick, unattended operated system according to claim 1, it is characterized in that: said child node is provided with 3 servers at least, and all is connected with head node through switch.
