Describe embodiments of the present invention in detail below with reference to drawings and Examples, how the application technology means solve technical matters to the present invention whereby, and the implementation procedure of reaching technique effect can fully understand and implements according to this.Need to prove that only otherwise constitute conflict, each embodiment among the present invention and each feature among each embodiment can mutually combine, formed technical scheme is all within protection scope of the present invention.
In addition, can in the computer system such as one group of computer executable instructions, carry out in the step shown in the process flow diagram of accompanying drawing, and, though there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.
First embodiment
Fig. 1 is the functional sequence block diagram according to the unit of the preparation memory file system of first embodiment of the invention, below with reference to Fig. 1, describes each ingredient of this unit in detail.
As shown in Figure 1, this unit comprises: creating environments module (hereinafter to be referred as the CreateOS module) 11, software package creation module (hereinafter to be referred as the CreatePkg module) 12, software package warehouse creation module (hereinafter to be referred as the CreateRepo module) 13, core document system creation module (hereinafter to be referred as the Createbase module) 14 and memory file system creation module (CreateRamfs module) 15.
Need to prove that each module is based on the ubuntu11.10 environment and disposes in the present embodiment.
Wherein, CreateOS module 11 is for the running environment of creating and dispose whole memory file system production unit.
As shown in Figure 1, main user identification code (ID), the configuration operation environment that checks current operation of CreateOS module 11, set up environment indices and running environment and configuration file checked.
More specifically, check that at first whether run user ID is true, namely judges whether to be authority (root) user, if for root user then be judged as true and pass through, if user ID is not root user, then be judged as vacation, out of service and prompting user's rights of using (root) identification code is carried out.Wherein, root user refers to the power user in unix system (as AIX, BSD etc.) and class unix system (as the (SuSE) Linux OS of each distribution version such as Debian, Redhat, Ubuntu) and Android system.Root is power user unique in the system, has authorities all in the system, as starts or stops a process, deletion or increase user, increase or forbidding hardware etc.
When the active user was root user, CreateOS module 11 was obtained the software package of disposing running environment.Particularly, obtain main catalogue by reading the setvars file, comprise main catalogue such as input, output, repo, script in this setvars file, move at CreateOS, every the catalogue that comprises in the traversal setvars file, and use " mkdir " to order the environment that creaties directory, realize the deployment of running environment.
At last, the configuration operation environment, and check whether important configuration file exists.For example: the listing file of installation system version list file, file system and tool system configuration file.If these files exist, then configuration file is transferred to below the corresponding catalogue, for example: the system version tabulation transfers to/the NovaOS/input/config/ catalogue under.The file that does not exist then out of service and prompting to lack.
Check the needed dependence environment of operation, check namely whether the software package of running environment all is mounted, for example: the dependence bag of the dependence of compiling bag and making memory file system.Preferably, whether all install by the environment that the FLAG Mark Detection relies on, if all install by then FLAG is 0, will to give the FLAG assignment be 1 if lack dependence, out of service and the software package that lacks of prompting and the method for installation all need to detect relying on environment at every turn then.
In addition, after configuration is improved, transmit the parameter of CreatePkg module 12 and CreateRepo module 13.When parameter is true time, then can carry out corresponding module, be the module of then inoperation correspondence of vacation.
Need to prove, similar with CreateOS module 11, created memory file system if once utilize the memory file system of present embodiment to prepare the unit before, then when this creates new memory file system, the operation that can omit CreatePkg module 12 and CreateRepo module 13 by the mode of transmitting parameter, just when another memory file system of preparation, only move core document system creation module 14 and memory file system creation module 15, can save preparation time like this.
Whether the software package that 12 detections of CreatePkg module are to be compiled all compiles is finished, if testing result is for denying, then the software package that will not compile compiles according to setting packet format, the software package that all compilings are finished is stored in the software source catalogue then, and software package wherein to be compiled comprises dsc bag, source code bag, scale-of-two bag, kernel bag and drives bag.
Preferably, the form that can unify dissimilar software packages to be compiled in advance by setting means, for example, setting means can be that the uniform format with dissimilar software packages is to comprise software package title, version number, current format type and the form of the Format Type that will compile.For example, the scale-of-two bag is name-version-bin.tar.gz; The source code bag is name-version-src.tar.gz; The dsc bag is name-version.dsc.Wherein, each field uses "-" to distinguish, the name of Name representative bag, and the version number of version representative bag, bin represents the scale-of-two bag, and src represents the source code bag, and Dsc represents deb bag source code bag.The form (i.e. Bian Yi form) of Tar.gz representative packing.Then the CreatePkg module detect software package to be compiled all compiling the software package of not compiling is compiled into the software package of deb packet format when not finishing.
For example, in the NovaOS system, whether fully the compiling of software package to be compiled under the CreatePkg module 12 detection/NovaOS/input/app catalogues is finished, if also there is the not software package of compiling, the software package of then treating compiling compiles according to setting packet format, wraps in file/var/NovaOS/build/.buildlist simultaneously and records display format: " bag name OK time ".The then display format " bag name fail time " if compiling makes mistakes, prompting reports an error.
More specifically, Createpkg module 12 travels through each sub-directory of input catalogue successively, check the application software (app) under it, whether kernel (kernel) and driving (driver) sub-directory exist the not software package of compiling, if there is not composing software bag in current sub-directory, then composing software does not pack the software package that makes the deb packet format, and the deb bag that compiling is finished is put among software source catalogue/NovaOS/repo/update, wherein, deb comprises the kernel bag, drive bag, use this three classes bag of bag, they are corresponding one by one with corresponding catalogue respectively.If current sub-directory does not exist the software package of not compiling then to skip, software package all sub-directories in traversal input catalogue that read in the next sub-directory finish.
Need to prove, normal conditions, kernel is finished in compiling, need be installed to restarting systems in the translation and compiling environment to kernel, could compile driver module, otherwise the driving version that will cause compiling does not match, and kernel can't load.And dsc bag, two advances bag, and the src bag all needs manually to produce and generate unified available bag by different Compilation Methods.But, the CreatePkg module of present embodiment waits to compile the form of dissimilar bags by the stipulated form unification, when the compiling kernel, keep the source code after kernel compiles, and the source code catalogue is connected to/lib/modules/ kernel version/build catalogue by instrument " ln ".By given core version number, when compiling drives, obtain the kernel version information, specify in/lib/modules catalogue kernel version, find the translation and compiling environment compiling to drive, generate spendable bag.Therefore, use the deb bag to manage by the CreatePkg module, can solve and to realize for example problem of the unified compiling of dsc bag, scale-of-two bag, source code bag, kernel bag and driving bag of various definitions different-format bag in the prior art.
The software source directory creating software package warehouse that CreateRepo module 13 obtains based on Createpkg module 12.
CreateRepo module 13 detects further whether the software source catalogue that Createpkg modules 12 obtain is an effective source, if testing result is for being then it to be generated a software package warehouse.
CreateOS module 11 is transmitted parameter and is given CreateRepo module 13, and the parameter value of CreateRepo module 13 is true time, checks then whether software source catalogue/NovaOS/repo/ is an effective source.When the parameter value of CreateRepo module 13 is false, skip the operation that CreateBase module 14 is directly carried out in inspection.Can omit the operation of CreateRepo module 13 like this, save time.
Particularly, at first use the instrument md5sum about message digest algorithm, for example, the md5sum instrument travels through each software package under this software source catalogue/NovaOS/repo/, and generates MD5 detected value listing file.If the MD5 detected value listing file that generates before existing and identical with the MD5 detected value listing file of current generation represents that then this software source catalogue is an effective software source, then it is generated with the software package warehouse.The MD5 detected value listing file or twice tabulation that generated if there is no are inequality, determine that then this software source catalogue is an invalid software source, show that namely current software source needs to upgrade.
When the software source catalogue is an invalid software source, preserve MD5 detected value listing file under/NovaOS/repo/ catalogue, and the order of the software source catalogue of use deb bag regenerates a software source catalogue.Order " dpkg-scanpackages " in debian, the ubuntu of (SuSE) Linux OS distribution version, it is to make deb bag index list instrument, be mainly used to create the source of deb bag, the order specification be " dpkg-scanpackages[option...] binary-dir〉Packages ", so can utilize " dpkg-scanpackages-m repo/dev/null|gzip〉repo/Packages.gz " to regenerate the software source catalogue.
Createbase module 14 is according to the kernel version of specifying the memory file system appointment that will make, from the software package warehouse, obtain corresponding installation file and configuration file with preparation core document system, the core document system refers to a complete system that simplifies, satisfy the deb packet function is installed, bash environment and basic storehouse.And memory file system is based on the file system that the core document system makes.
Particularly, dispose the core document system environments and by the core document system environments of disposing the bag that needs is installed, configuration installation file, deb bag source address are with preparation core document system.
For example, when the kernel version name of the memory file system appointment that will make is the EDU version, then imports this title and pass to CreateBase module 14, if do not have version name then out of service.CreateBase module 14 obtains EDU version installation kit listing file and configuration file from/NovaOS/input/config, establishment/var/NovaOS/rootfs file directory, core document system under/NovaOS/input/core/ catalogue is unziped to/the var/NOvaOS/rootfs catalogue in, the software source of profile system and copy installation kit listing file, install.sh file are to the rootfs catalogue.Utility command " chroot$ROOTFS./install.sh " resolve the package list file automatically, installation kit is in rootfs core document system.Behind aforesaid operations, installation the core document system of a customization, need to prove, except the EDU version, can also customize for example core document system of other versions such as HPC, ISO, TDX.
CreateRamfs module 15 is created memory file system based on the core document system.
Particularly, create kernel and the initrd.img file of memory file system based on the rootfs file directory.For example, the kernel under the copy/var/NovaOS/rootfs catalogue is created the memory file system of initrd.img customization to generating under the release directory.
The core document system that 15 pairs of CreateBase modules of CreateRamfs module 14 generate carries out the init script to be created, and init mainly calls to install and uses and the initialization memory file system, is made into initrd.img internal storage starting file.
Particularly, give CreateRamfs module 15 by specifying the rootfs path, CreateRamfs module 15 reads/the NovaOS/input/config/ramfs.conf file, comprises kernel module, required application file name, dynamic base in the ramfs.conf file.Traversal each filename of ramfs.conf also copies in the initramfs catalogue that creates, utility command " chroot./sbin/ldconfig ", " chroot./sbin/depmod$KVERSION " generates storehouse and the kernel configuration relies on, will utilize then that the lzop tool of compression is compressed into can be in internal memory fast the miniature custom file system of decompress(ion) copy under the indicated release catalogue.Because use the lzop tool of compression to compress the initrd.img file, the decompressing files system speed can obviously be promoted in internal memory.
