Abstract
The invention provides a quick medium-free upgrading method for a Linux system. According to the upgrading method, the smoothness and the quickness during updating and upgrading of the Linux system are realized by functions of modifying an initialized boot file of a memory, adding an automatic connection remote server, downloading an upgrade data packet, checking the file integrity, decompressing an alternate file, executing the rollback operation and the like; in addition, the updating and the upgrading can also be realized under the condition of not installing mobile media such as a compact disc and a U flash disk and large-scale quick deployment can be realized.
Description
Technical field
The invention belongs to (SuSE) Linux OS technical field, relate to a kind of medium linux system upgrade method of exempting from fast.
Background technology
Along with social development, computer application relates to social every field, and as one increase income, stablize, safe operating system, (SuSE) Linux OS is widely used in each field.Increasingly serious along with the development of software engineering and computer information safe situation simultaneously, the software upgrading of (SuSE) Linux OS is more frequent, and this just needs (SuSE) Linux OS constantly upgrade and upgrade, to guarantee the information security of system.
During the larger (SuSE) Linux OS edition upgrading of earthquake, due to the new and old edition compatibling problem of some kernel softwares and file system, can not by the mode of update software version, carry out upgrade-system simply, often need to reinstall system and dispose business.This not only makes the service disconnection long period, is also unfavorable for automated quick deployment.This just need a kind of level and smooth, (SuSE) Linux OS upgrades upgrade method fast.
Summary of the invention
The object of this invention is to provide a kind of medium linux system upgrade method of exempting from fast.
Technical matters to be solved by this invention is that a kind of medium linux system upgrade method of exempting from fast need to be provided, this renewal upgrade method can realize fast level and smooth in renewal when upgrading of linux system, also can without removable mediums such as fixing disc, USB flash disks in the situation that, realize upgrading and upgrade.In order to solve the problems of the technologies described above, a kind of technical scheme provided by the invention is as follows:
First by the system root partition of upgraded version and/boot subregion pack respectively make packet (linux system edition upgrading be mainly root partition and/upgrading of boot subregion, the subregion that other users arrange does not relate to system upgrade), be placed in remote server; As without remote server, if environment has sufficient space, also can directly packet be placed in environment to be upgraded.Revise initialization internal memory boot files (initrd), make can certainly be dynamically connected remote server download upgrading data packet of system when starting, then carry out integrity checking and back up original root partition file and/boot partitioned file, then decompress(ion) upgrading data packet to root partition and/boot subregion, substitute respectively original root partition file and/boot partitioned file, finally check that whether upgrading is successful, if the system of unsuccessful rollback backup, if successful normally restart, complete whole escalation process.Its implementation method comprises the following steps:
By the system root partition of upgraded version and/boot subregion packs respectively and is made into upgrading data packet, be placed in a fixed route of remote server; As without remote server, if environment has sufficient space, also can directly packet be placed in environment to be upgraded;
2. revise the initialization internal memory boot files (initrd) of redaction, add from being dynamically connected the functions such as remote server downloading data bag, integrity checking and decompress(ion) alternate file;
3. the kernel of redaction and initialization internal memory boot files (initrd) are copied to environment to be upgraded, the starting system of laying equal stress on;
4. system enters the initrd of modification, complete successively following operation: check whether to need the label of upgrading, be certainly dynamically connected remote server and download upgrading data packet, check downloading data bag integrality, back up original root partition and/boot partitioned file, the integrality that checks backup file, decompress(ion) upgrading data packet substitute original file, check the integrality of upgrade file, by upgrading label put no, restarted upgrading, if certain the step integrity checking in escalation process does not pass through, also has corresponding rollback operation.
The invention has the beneficial effects as follows, it completes by realizing with initrd the function of downloading upgrading data packet and completing upgrading automatically, and provide upgrading integrity checking and the failed rollback operation function of upgrading, can realize fast level and smooth when the renewal upgrading of linux system, also can without removable mediums such as fixing disc, USB flash disks in the situation that, realize and upgrade upgrading, and can realize large-scale rapid deployment.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of the realization of the embodiment of the present invention.
Embodiment
A kind of medium linux system upgrade method of exempting from fast of the present invention is described in detail below, comprises the following steps:
By the system root partition of upgraded version and/boot subregion packs respectively and is made into upgrading data packet, be placed in a fixed route of remote server; As without remote server, if environment has sufficient space, also can directly packet be placed in environment to be upgraded;
2. revise the initialization internal memory boot files (initrd) of redaction, add from being dynamically connected the functions such as remote server downloading data bag, integrity checking and decompress(ion) alternate file;
3. the kernel of redaction and initialization internal memory boot files (initrd) are copied to environment to be upgraded, the starting system of laying equal stress on;
4. system enters the initrd of modification, complete successively following operation: check whether to need the label of upgrading, be certainly dynamically connected remote server and download upgrading data packet, check downloading data bag integrality, back up original root partition and/boot partitioned file, the integrality that checks backup file, decompress(ion) upgrading data packet substitute original file, check the integrality of upgrade file, by upgrading label put no, restarted upgrading, if certain the step integrity checking in escalation process does not pass through, also has corresponding rollback operation.
Claims (4)
1. exempt from fast a medium linux system upgrade method, comprise the following steps:
