The present invention program is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, Fig. 1 is the process flow diagram preserving user configured method under a kind of linux system provided by the present invention, and the method is drawn together:
S11: the root file system initrd under utilizing Open-Source Tools to set up linux system, and new directory newroot is created in internal memory;
Wherein, Open-Source Tools comprises busybox instrument, can create simple file system.After having created new directory newrooot, carry ramfs file system or tmpfs file system.Utilize ramfs or tmpfs can improve ramdisk performance, and take Installed System Memory without the need to unnecessary, ramfs and tmpfs can adjust committed memory size dynamically, and wastes memory headroom in advance unlike ramdisk.
S12: find out configuration file in root file system initrd, beats compressed package and becomes configuration compressed file by configuration file, other system file except configuration file in root file system initrd is beaten compressed package and becomes system compresses file;
Wherein, the configuration file relating to user's Set up-conservancy is found out in root file system initrd, configuration file is beaten compressed package separately, form configuration file compressed package and called after config-origin.tar.gz, compressed package is beaten in other system file classification in root file system initrd, forms each system compresses file of classification.
S13: compressed file and system compresses file migration will be configured in nonvolatile memory, and configuration compressed file solution is depressed in the new directory newroot in internal memory and forms configuration file copy;
S14: the change configuration file instruction receiving user's input, under the effect of change configuration file instruction, carries out change to the configuration file copy in internal memory and obtains new configuration file;
S15: utilize Set up-conservancy order that new configuration file is beaten compressed package, is compressed to new configuration file in nonvolatile memory to be formed and newly configures compressed file;
Wherein, utilize Set up-conservancy order config-save, compressed package is beaten to new configuration file, and called after config-user.tar.gz, form config-user.tar.gz compressed file, nonvolatile memory described in carry, preserves config-user.tar.g compressed file to nonvolatile memory, unloads nonvolatile memory after having preserved.
S16: during new startup root file system initrd, decompress(ion) newly configures compressed file and obtains new configuration file in the nonvolatile memory, using new configuration file as the configuration file under current linux system.
Wherein, when root file system initrd starts initializtion script, utilize mount order carry nonvolatile memory to described root file system initrd, detect in nonvolatile memory and whether there is config-user.tar.gz compressed file, if existed, decompress(ion) config-user.tar.gz compressed file, to newroot/etc catalogue, forms new configuration file and as the configuration file of current Linux system.
Concrete above, such as, first using busybox instrument, making easy file system, for making initrd.
Compressed package is beaten in the final system file classification run, and a compressed package called after config-origin.tar.gz made a call to separately by the file such as, relating to user's Set up-conservancy in/etc catalogue, and other system file beats compressed package by the needs classification of oneself again.All compressed packages are placed into nonvolatile memory, and nonvolatile memory can be hard disk, and DOM dish, CF card, plate carry flash etc.
Then, start in initializtion script at initrd and increase following functions: establishment newroot catalogue, newroot catalogue carry ramfs or tmpfs;
Secondly, start in initializtion script at initrd and continue to add following process: mount order carry nonvolatile memory to initrd /mnt catalogue, check whether to there is config-user.tar.gz, if there is decompress(ion) config-user.tar.gz to newroot/etc catalogue, as the configuration file of final system; If there is no config-user.tar.gz then decompress(ion) config-origin.tar.gz, with the content of the config-origin.tar.gz configuration file as final system.
Again, the last of initializtion script is started at initrd, other necessary system files of decompress(ion) are to newroot catalogue, and unload nonvolatile memory with umount, finally perform chroot or switch_root order, systematic evaluation to newroot, after above operation, namely the root directory of presenting to the final system of user operation is the newroot catalogue of initrd.
After order such as use switch_root etc. is switched to final system, the nonvolatile memory utilizing mount order carry to deposit daily record is to/var/log catalogue.
Finally, the order of increase user's Set up-conservancy is needed in the final system made, such as name config-save, the function of this order beats compressed package to configuration file, compressed package called after config-user.tar.gz, carry nonvolatile memory, preserves config-user.tar.gz to nonvolatile memory, unloading nonvolatile memory.
Therefore, utilize ramfs or tmpfs can improve ramdisk performance, and take Installed System Memory without the need to unnecessary, ramfs and tmpfs can adjust committed memory size dynamically, and wastes memory headroom in advance unlike ramdisk.While resolution system file security sex chromosome mosaicism, independently order is had to allow user preserve configuration, improve the reliability of amendment configuration file, user's arbitrary disposition, when causing confusion, be easy to recover factory-said value, only need to provide order that config-user.tar.gz is deleted and can be completed, namely when user's configuration causes confusion, only need the new configuration compressed file on deletion nonvolatile memory just passable, leave configuration compressed file, this configuration compressed file is exactly the compressed file of original configuration file, so easy recovery original configuration.And, there is the nonvolatile memory independently preserving daily record, facilitate abnormal information to follow the tracks of.
User configured method is preserved under a kind of linux system provided by the present invention, configuration file separates from root file system separately, independent packing is compressed, it is deposit in the nonvolatile memory that other system file becomes compressed package, be so system file be deposit in the nonvolatile memory, user can not change the data on nonvolatile memory, then system file can not be modified, and the security of such system file ensures.
And, for configuration file, configuration file is that packing becomes compressed file separately, the compressed file of configuration file is also deposited in the nonvolatile memory, this configuration file is exactly original configuration file in fact, then the compressed file of original configuration file deposits in the nonvolatile memory, and be leave in the catalogue on internal memory to the configuration file obtained after the compressed file decompress(ion) of configuration file, namely the configuration file after decompress(ion) is arranged in memory directory, user can change the data on internal memory, configuration file then on memory directory can be changed by user, new configuration file after change is compressed on nonvolatile memory, compressed file then after new configuration file compression deposits in the nonvolatile memory, after system restart, nonvolatile memory exist the compressed file of original configuration file and the compressed file of new configuration file, deposit in case at the compressed file of new configuration file, use new configuration file, do not use original configuration file, the compressed file solution of new configuration file is pressed into the configuration file of new configuration file as current system, save user like this to arrange, realize in this way while guarantee system file security, solve user configured preservation problem, user's configuration can be preserved.
