Abstract
The invention relates to the technical field of management of cloud computing, and in particular relates to a method for batch updating system patches of a Linux virtual machine. The method comprises the steps of firstly selecting a mirror image to be updated with the patches to establish the virtual machine; then updating the system patches via the virtual machine, using yum update; after completing, distributing the mirror image updated with the patches to each physical node; then combining the changes of the mirror image into a corresponding virtual machine snap; and at last restarting the virtual machine, thus completing the patch update. The method for batch updating the patches of the virtual machine provided by the invention is simple and convenient, and can be applied to updating the patches of the virtual machine.
Description
Technical field
The present invention relates to cloud computing administrative skill field, refer to especially a kind of batch updating Linux dummy machine systemThe method of patch.
Background technology
Under cloud computing environment, virtual machine is widely used, and no matter is office computer or application server orderBefore all become unified centralized management by Decentralization; Therefore, the security of virtual machine seems more important. OrderAlthough front unified management of virtual machine, the renewal of system mend is because technical problem is always by each voidPlan machine user oneself solves, and even individual user is forbidden system update service, and this is just the management band of virtual machineCarry out very large potential safety hazard, for this situation, generally adopt several modes:
1, in the inner client of installing of virtual machine, system mend is upgraded in timing.
2, the each self refresh of virtual machine user, makes regular check on.
There is following drawback in above method:
1, client renewal process tends to be forbidden by user, cannot complete patch and upgrade operation.
2, the each self refresh of virtual machine user, easily causes network congestion, waste bandwidth
3, no matter waste of manpower cost, be the management of patch or regular inspection, all consumes human cost.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of side of batch updating Linux dummy machine system patchMethod, solves the deficiency that conventional method exists, and provides a solution for improving virtual machine patch renewal efficiency.
The technical scheme that the present invention solves the problems of the technologies described above is:
Described method comprises the steps:
Step 1: the mirror image that selection will be upgraded patch creates virtual machine;
Step 2: adopt yumupdate, upgrade system mend by virtual machine;
Step 3: after completing, the mirror image that has upgraded patch is distributed to each physical node;
Step 4: mirror image is changed and merges to corresponding virtual machine snapshot;
Step 5: after virtual machine is restarted, patch has upgraded.
Described mirror image creates virtual machine, is directly to create virtual machine by mirror image.
Described mirror image distribution, refers to the mirror image having upgraded after patch is transferred to each physical node, alternativeThe original mirror image of reason node.
Described merging, refers to the variation of mirror image is reconsolidated to virtual machine snapshot file, makes patch file rawEffect.
Method batch updating virtual machine patch of the present invention, simple and fast; Method of the present invention reduces human cost,Only need keeper to upgrade after mirror image patch, system completes distribution and the union operation of mirror image automatically; The present inventionMethod improve the security of virtual machine, guarantee all virtual machines system mend that can upgrade in time.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is flow chart of the present invention;
Fig. 2 is technical schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, 2, specific implementation process of the present invention is as follows:
1, select to upgrade the mirror image establishment virtual machine of patch.
2, upgrade system mend by virtual machine.
# adopts yumUpdate to upgrade system mend
After # completes, forbidding yumUpdate service, avoids virtual machine automatically to upgrade, and causes restarting
3,, after completing, the mirror image that has upgraded patch is distributed to each physical node.
4, mirror image is changed and merges to corresponding virtual machine snapshot.
5, after virtual machine is restarted, patch has upgraded.
