Embodiment
For above and other objects of the present invention, feature and advantage can be become apparent, cited below particularlyly go out preferred embodiment, and cooperate appended graphicly, be described in detail below:
The present invention is a kind of method of upgrading image file, this method is applied in the server, see also shown in Figure 1, at least be provided with a storage element 1 (as: flash memory (flash)) in the server, server is partitioned into a start block 10 in advance in storage element 1, one first image area 12 and one second image area 14, the block 10 of wherein starting shooting stores a start loading procedure (boot loader) in advance and an image upgrades conditional code, first image area 12 stores a work image file (workable image file) in advance, second image area 14 is to be used for storing a backup image file (second image file), and the backup image file duplicate be identified in first image area 12 can normal operation the work image file, see also shown in Figure 2, when the server desire will newly be worked image file when being updated to storage element 1, server is according to carrying out the following step:
(1) the present work image file that will be stored in first image area 12 copies to second image area 14 as the backup image files, and the image file of will newly working copies to first image area, 12 conduct work image files: in the present invention, in order to determine the integrality of the new image file that the server desire is upgraded, reach definite new work image file and finished the action of renewal, the step of server update work image file and backup image file comprises:
(10) begin the initialization upgraded, image is upgraded conditional code be set at first numerical value, first numeric representation is not the start first time after the work image file of first image area 12 is updated at present: in a preferred embodiment of the present invention, it is with eight binary number value representation that image upgrades conditional code, wherein first is to represent whether be the start first time after the work image file of first image area 12 is updated, first binary value " 0 " is expressed as start for the first time, and it not is start for the first time that first binary value " 1 " is expressed as; Whether the work image file of second bit representation first image area 12 is updated success, and the work image file can operate normally, the binary value of second position " 0 " is expressed as and upgrades successfully and can operate normally, and the binary value of second position " 1 " is expressed as the renewal failure and can't operates normally; When then representing to start shooting, the 3rd position to carry out boot action with work image file or backup image file, binary value " 0 " expression of the 3rd position is carried out boot action with the work image file, binary value " 1 " expression of the 3rd position is carried out boot action with the backup image file, as for eight positions, the 4th position to the, then still undefined.So, in this embodiment, when server begins to carry out initialization, be not start for the first time, and upgrade, and server should be with the work image file when this start shooting, be that first setting value of upgrading conditional code with image is " 10000000 ";
(11) judge newly whether the content of work image file is complete, if carry out step (12), otherwise carries out step (10); Whether complete in this embodiment, judge content the method for new work image file, whether the amount of capacity that can be the new work image file that inspection receives is wrong; Or check that according to one calculation equation calculates the content of new work image file, and in order to obtaining a check code (as: check sum), and judge whether check code is correct, whether complete in order to the content of judging new work image file;
(12) when the make new advances content of work image file of judgement be complete, be that setting of image renewal conditional code is a second value, and the work image file in first image area 12 copied to second image area 14 as the backup image file, and the image file of newly working copies in first image area 12 as the work image file; In this embodiment, second value is used for representing not to be start for the first time, if and server upgrades with the backup image file, whether can upgrade success in this step and can't learn as for follow-up, and in order to simplify follow-up treatment step, so the second value that image upgrades conditional code is set at " 10100000 ";
(13) image file that judges whether again successfully will newly work duplicates in first image area 12, if carry out step (14), otherwise carries out step (15);
(14) image is upgraded conditional code and be set at third value, because before this step, determined that new work image file successfully copies in first image area 12, therefore, third value will represent that not necessarily the work image file successfully duplicates in first image area 12, but must represent that the work image file upgrades back start for the first time and will carry out boot action with the work image file in first image area 12 when starting shooting again, obtaining the conditional code to reach the information that to carry out boot action with the work image file in first image area 12 when starting shooting again for the work image file upgrades back start for the first time so that can upgrade from image during follow-up again start.So among this embodiment, the binary code values that image upgrades the third value of conditional code can be set at " 01000000 " or " 00000000 ";
(15) image is upgraded conditional code and maintain second value, again start, because before this step, determined that new work image file does not successfully copy in first image area 12, and in the content of judging new work image file is complete step, (has been step 12), has been preset as and is used for expression and upgrades start for the first time, if and server upgrades with the backup image file, so, in this step, need not to change the binary numeral that image upgrades conditional code.
(2) start again, and upgrade the conditional code decision according to image and will carry out in-cycle work again with work image file or backup image file; In this embodiment, after server is carried out the step of renewal work image file, image upgrades conditional code may be first numerical value (i.e. " 10000000 "), second value (i.e. " 10100000 "), or third value (i.e. " 01000000 " or " 00000000 "), or image renewal conditional code is set to one the 4th numerical value, the 4th numerical value upgrades for the first time and again after the start in order to be illustrated in, server can't be with the successfully executive operating system of image file of working, and work image file and fail the running, and need with the backup image file start shooting again again.In this embodiment, the 4th numerical value is with binary numeral " 11100000 " expression, and upgrades the step that conditional code is started shooting again according to image when server, sees also shown in Figure 3ly, and comprising: start shooting again (200);
(201) upgrade the conditional code decision according to image and will carry out in-cycle work again with work image file or backup image file, if upgrading conditional code, the image that receives is set to third value, promptly indicate to carry out in-cycle work again with the work image file, then carry out step (202), and, then carry out step (208) if the image that receives upgrades conditional code and is set to first numerical value, second value or the 4th numerical value;
(202) image is upgraded conditional code and be set at the 4th numerical value, in this step, be with image upgrade conditional code be set at the 4th numerical value be the hypothesis server can't with work image file successfully start the operating system, so that in follow-up step, when server really can't successfully start the operating system with the work image file, not be used in again and set;
(203) start the operating system;
(204) decision operation system being activated of success whether if carry out step (205), otherwise carried out step (206);
(205) the decision operation system is activated or is activated by the backup image file by the work image file, if start the operating system by the work image file, then carry out step (207), otherwise, represent that promptly operating system is to be activated by the backup image file, then carries out step (210);
(206) image is upgraded conditional code and keep the 4th numerical value, return step (200) and handle;
(207) image is upgraded conditional code and be set at first numerical value, represent that promptly the work image file is updated smoothly, the image file of after this can working starts the operating system, and promptly finishes.
(208) received image renewal conditional code is set to first numerical value in this step, second value or the 4th numerical value one of them, wherein first numerical value is to be started the operating system by the work image file, and second value or the 4th numerical value are to be started the operating system by the backup image file, therefore, this step still need judge by work image file start the operating system or by the backup image file start the operating system, if start the operating system and carry out step (209) by the backup image file, otherwise, i.e. expression is to be started the operating system by the work image file, then carries out step (203);
(209) start the operating system by the backup image file in second image area 14, promptly, carry out step (204) again with backup image file initiating task;
(210) the backup image file of second image area 14 is copied in first image area 12 as the work image file, the state before promptly first image area 12 and second image area 14 return to and upgrade is handled according to the following step again;
(211) judge whether storage element 1 recovers success, if carry out step (212), otherwise, carry out step (213);
(212) image is upgraded conditional code and be set at first numerical value, enter the state that wait is started shooting next time again;
(213) image is upgraded conditional code and be set at second value, enter the state that wait is started shooting next time again.
By as can be known above-mentioned, the storage element 1 of server is cut apart two independently image areas, and deposit the work image file respectively and back up image file, after being updated of the work image file success of storage element 1, server can select work image file or backup image file to finish the processing that starts the operating system automatically, and if server can be selected with backup after image file finishes the processing that starts the operating system, can recover the state of storage element 1 before renewal automatically again, and then solve the problem that traditional server is operated inconvenience and can't be recovered storage element 1 automatically.
The above only is a specific embodiment of the present invention, but structural attitude of the present invention is not limited thereto, and anyly is familiar with this skill person in field of the present invention, can think easily and variation or modification, all can be encompassed in the claim of this case.
