Abstract
The invention relates to a method for upgrading Linux system software in the field of computers, aiming at providing a method for safely and remotely upgrading an embedded Linux system software so as to solve the problem that multi-terminal software is inconvenient to maintain in the prior art and solving the problem that a fault is difficult to eliminate during upgrading. The method comprises the following steps of: downloading an upgrading file to the client from a distal upgrading center, writing the upgrading software into a backup region equative to the original storage region of software to be upgraded, modifying a start location of the software to be upgraded to be the backup region, setting the upgrading flag to be upgraded, and then restarting a system; checking the upgrading tag, if the upgrading flag is not upgraded, starting the software to be upgraded in the original storage region of the software to be upgraded; if the upgrading tag is upgraded, setting the upgrading tag to be upgraded, and then reporting an upgrading center that upgrading is successful. By adopting the scheme, remote upgrading on multiple clients can be realized, and the problem that the fault is difficult to eliminate once the fault is caused in the background art can be solved.
Description
Technical field
The present invention relates to the upgrading way of linux system software in the computer realm, comprise the upgrade method of system software, file system and application software.
Background technology
The linux software systems comprise linux kernel and file system and application software.Kernel and file system are together upgraded, and application software is upgraded separately.
Software systems need be supported long-time maintenance, the many and widespread situation at the embedded device product, and it is extremely inconvenient to carry out field maintemance one by one.
Software systems produce fortuitous event and cause upgrading unsuccessful in carrying out escalation process, equipment can't normally move, the difficult upstate that recovers.
Summary of the invention
The invention is intended to provide a kind of method of embedded Linux system software safety long-distance upgrading,, also will solve the difficult problem of recovering when upgrade failure simultaneously to solve the problem of multiple terminals software maintenance inconvenience in the prior art.
Purpose of the present invention can reach by following measure: a kind of method of embedded Linux system software safety long-distance upgrading may further comprise the steps:
One, from the equipment upgrade center download and upgrade file of far-end to described client, described upgrade software is write and is upgraded the backup area of the former memory block of software peer, the enable position that modification is upgraded software is described backup area, described upgrading zone bit is set for upgrading, and system restarts then;
Two, check the upgrading zone bit,, be upgraded software from being upgraded software former memory block startup if the upgrading zone bit is not upgrading; If described upgrading zone bit is for upgrading, then it is set to not upgrade, and reports that then equipment upgrade center upgrades successfully, jumps out whole upgrade step then.
In such scheme, adopt mode communications such as cable or radio to be connected between described equipment upgrade center and client, equipment upgrade center and client are the computer system that possesses necessary hardware configuration.
Comprised the renewal version that is upgraded software in the described equipment upgrade center, client is obtained the descriptor of software upgrading from equipment upgrade center, and the comparison of descriptor and institute's saved software descriptor by software upgrading determines whether this software can upgrade.
After upgrading successfully, also need described backup area is labeled as new former memory block, simultaneously described former memory block is labeled as new backup area, prevents from when updating operation next time, directly upgrade file to be write current former memory block of using, cause unnecessary trouble.
Such scheme has been realized the remote upgrade of multi-client, only needs to get final product by the teleinstruction of equipment upgrade center the batch upgrade of multi-client; And upgrade file can directly not cover the former memory block of using when upgrading, just be identified as new former memory block after only in backup area, moving successfully, finish upgrade step, can use the software in the backup area to save when in escalation process, accident occurring, avoid in a single day upgrading in the background technology and made mistakes with regard to the problem that is difficult to recover.
Further: the described software that is upgraded comprises the linux application program, and in described step 1 in the safety long-distance escalation process of linux application program: described " described upgrade software being write and is upgraded the backup area of the former memory block of software peer " is " backup area that described upgrade software is write and is upgraded the former memory block of software catalogue at the same level ";
In described step 2 in the safety long-distance escalation process of linux application program: if described upgrading zone bit is then deleted the application program of described former memory block for upgrading.
The effect of this programme is: formulated more detailed scheme at the upgrading of linux application program, realized the technique effect same with first scheme, " described upgrade software is write and is upgraded the backup area of the former memory block of software catalogue at the same level " and define the writing position of upgrade file, unlikely confusion when multiple utility program is upgraded is convenient to management; And the application program of the described former memory block of deletion after upgrading is finished, the application program that meaning is promptly deleted legacy version has been saved storage space, avoids the confusion of follow-up management.
Further: the described software that is upgraded comprises linux kernel and linux file system,
Further comprising the steps of behind the safety long-distance escalation process of linux kernel and linux file system in described step 2:
A, restart the back and check the upgrading zone bit, if for upgrading then change step B over to, if for upgrading then change step C over to;
B, check the upgrade status position,,, upgrade successfully then change step B3 over to if be if for upgrading then change step B2 over to if for upgrading then change step B1 over to;
B1, the updating result position is set is upgrading failure, the upgrading zone bit is set is upgrading, the change kernel starts and the position of file system loading is described former memory block, changes step C over to;
B2, the upgrade status position is set for upgrading, the updating result position is set for upgrading, the change kernel starts and the position of file system loading is described backup area, changes step C over to;
B3, the upgrading zone bit is set, changes step C over to for upgrading;
C, startup kernel and load document system then change steps A over to as starting failure;
D, check the updating result position,,, upgrade to fail then change step D3 over to if be if for upgrading then change step D2 over to if for upgrade successfully then change step D1 over to;
D1, the upgrade status position is set for to upgrade successfully, the updating result position is set for upgrading, described backup area is labeled as new former memory block, described former memory block is labeled as new backup area, the report equipment upgrade center is upgraded successfully;
D2, jump out whole upgrade step;
D3, the updating result position is set is upgrading, the report equipment upgrade center is upgraded successfully.
Described upgrade status position, updating result position and upgrading zone bit are the variable that is used to judge each state in the storage space.
The effect of this programme is: formulated more detailed scheme at the upgrading of linux kernel and linux file system, realized the technique effect same with first scheme, the perfect judgement of upgrade status in the escalation process making upgrading become safer, has avoided the generation of mistake.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
