Embodiment
Below in conjunction with the drawings and specific embodiments this programme is described in further detail:
As shown in Figure 1, the system of realization Embedded Application of the present invention comprises: upper application module and bottom operation supporting module.Wherein the former mainly is responsible for the exploitation of system business ability, comprises exploitation BOOT program and exploitation business procedure.The latter mainly is responsible for building system's operation platform, and comprising provides BOOT program running environment (comprising: BOOT kernel and simplify tool set) and business procedure running environment (comprising: professional kernel and customize tool set).Wherein the BOOT kernel, simplify tool set and BOOT program and constitute and start version, professional kernel, customization tool set and business procedure constitute business release.
Below be that example illustrates specific implementation process of the present invention with the blade server system.Deposited the startup version in the FLASHROM chip of each blade server.As shown in Figure 2, the FLASHROM chip software arrangement with the 2MB size is the example explanation.As can be seen from Figure, AMI BIOS is in the most significant end address of chip, takies 512KB.To the 0X180000 address field, taking 64KB from 0X170000, is the Mini boot that is responsible for the BOOT boot kernel is got up., be placed with the BOOT kernel, simplify tool set etc. to the 0X170000 address field from 0X0, the BOOT program is also placed in this interval.
In the present embodiment, the BOOT kernel is used for load operating BOOT program.Simplify tool set and be used for realizing functions such as basic system management and maintenance.Professional kernel is used for the load operating business procedure.The customization tool set is for functions such as the system management that realizes customization and maintenances.Mini BOOT program is used for decompress(ion) and starts version.In compilation process, earlier the BOOT kernel is compressed, to simplify in tool set and BOOT integration procedure to " file system " file again and compress, at last with them and BI OS and Min iBOOT program, according to illustrated address distribution situation, be incorporated in the image file of a 2MB and go.The image file that generates is fired in the FLASHROM chip of 2MB, just can be used for starting the MSTU veneer of USS platform.
Start version and business release and load flow process as shown in Figure 3.
When system started, bios program jumped to the operation of predefined address, was customized to here to jump to the operation of Mini BOOT position.The major function of Mini BOOT is exactly that the BOOT kernel of compression is copied to memory headroom and decompress(ion) operation, and responsible decompress(ion) is simplified tool set and BOOT program, finishes decompress(ion) and just moves the BOOT kernel afterwards.Can load the BOOT program automatically in the BOOT kernel operational process.
The BOOT program is responsible for finishing the loading of business release.The up-to-date business release of system leaves on the master control borad, and being used for provides the renewal download service to each blade server.According to certain regulation on version management, the difference of version on the business release that exists on the BOOT program comparison current single board and the master control borad.If version unanimity, the then business release on the direct loading monoboard of BOOT program; If version is inconsistent, then the BOOT program is downloaded new business release from master control borad, stores on the local hard drive and loads this business release.
In loading procedure, the BOOT program extracts professional kernel, customization tool set and business procedure from business release.Afterwards, the BOOT program adopts the KEXEC technology, moves professional kernel by the secondary kernel loads.The KEXEC technology is a fast start-up mechanism, allows the linux kernel of context startup by the kernel that has moved, and does not need through BIOS.
Professional kernel will move the CPU program after starting successfully automatically, so just finish the start-up course of total system.
Below specify following process flow of the present invention again:
Step 1 loads the BOOT kernel that starts in the version in the BIOS start-up course, BOOT boot kernel success back load operating BOOT program;
11) BIOS starts back operation Mini BOOT program;
12) Mini BOOT program copies the BOOT kernel of compression to memory headroom and decompress(ion) operation, and decompress(ion) is simplified tool set and BOOT program;
13) operation BOOT kernel, load operating BOOT program.
Step 2, the BOOT program is carried out the loading of business release, starts professional kernel, professional boot kernel success back load operating business procedure, business procedure is taken over the operation of system.
21) version information of the business release on comparison current single board and the master control borad, the up-to-date business release of BOOT program download version information stores on the local hard drive, and loads this operation business release;
22) in loading procedure, the BOOT program is extracted professional kernel, customization tool set and business procedure from business release;
23) after finishing loading, the professional kernel of BOOT program loading operation, professional boot kernel success back load operating business procedure, business procedure is taken over the operation of system.Wherein the load mode of professional kernel can select to adopt KEXEC kernel secondary load mode load operating.
Embedded implementation of the present invention is compared with original SUSE Linux server scheme, and the relative merits contrast is as follows:
(1) system's installation aspect: use embedded mode, will start version and BIOS and be incorporated among the FLASH ROM, only image file need be fired in the chip and got final product, a few minutes just can be finished the installment work of a veneer, and are efficient and convenient.And use SUSE Linux mode, and need to use earlier the mode of CD-ROM drive or disk mirroring, system is installed on the system disk, need dozens of minutes at least, installation rate is slow.
(2) system dimension aspect: use embedded mode, can freely control the size that starts version by reducing, the kernel version of main flow can control to about 1MB at present, if use the kernel of early version, can control fully in 512KB, should start version can be incorporated among the FLASH ROM of 2MB together with BIOS.And use SUSE Linux mode, and after system installed, it was bigger to take up room, and it is also cumbersome that customization is got up, and it also is bulky in time using the mirror image mode to install, and is unfavorable for starting maintenance and the upgrading of version.
(3) BOOT startup aspect: use embedded mode, the BOOT version is sintered to after the FLASH rom chip, the BOOT program just can normally start, and downloads software version and has moved, and need not artificially to intervene again.And use SUSE Linux mode, and install after the operating system, need land the copy start-up routine to hard disk, and revise the initialization script, the BOOT program can normally start like this.
(4) system maintenance aspect: use embedded mode, can be according to application demand, need kernel version and the software package program used in the custom-built system, the upgrading of kernel and software package and maintenance can be carried out together with business software.And use SUSE Linux mode, and upgrade kernel and software package, relate to the synchronous renewal of blade level, difficulty is bigger, does not also have the scheme of moulding to use for reference at present.
(5) purchase and technical support: use embedded mode, realize owing to can adopt from the mode of grinding exploitation, need not during use to buy and the outer service fee of amount paid, and can provide the rapid reaction support, and can customize system at any time according to application demand, can adapt to the variation demand of carrier class system business.And use SUSE Linux mode, and need payment to buy and service fee, and the technical support response speed is slow, be difficult to secure when being out of order.
(6) system stability: use embedded mode, adopt FLASH ROM to deposit the BOOT version, use the hard disk storing software version, thereby ensure that the BOOT version can not be damaged, as long as the BOOT version is not unusual, system just can start guiding, and instant hard disk breaks down, also can in time alarm replacing, reliability height.And use SUSE Linux mode; BOOT version and software version operate in the same hard disk operation system; the os starting environment appears unusually very likely damaging in the version operational process; at this moment system restart regular meeting is often hung up; and can not initiatively report any unusually, reliability does not guarantee.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention does, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
