Purpose, technical solution and effect are clearer, clear, and the present invention is described in more detail below.It should be appreciated that this place is retouched
The specific embodiment stated is only used to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, Fig. 1 is a kind of method preferred embodiment of the factory reset based on educational system of the present invention
Flow chart, as shown, itself comprising steps of
S1, original file systems are divided into three underlying file systems, topmost paper system and surface layer file system levels,
Wherein based on underlying file systems, topmost paper system is superimposed on underlying file systems, and surface layer file system is superimposed upon
In layer file system；
S2, using surface layer file system as final mount directory, when modifying to surface layer file system, will change
It is stored in topmost paper system；
S3, when needing to reset original file systems, empty topmost paper system, and pass through underlying file systems
Factory reset.
Through the invention, when the case where resetting occurs needing in operating system, topmost paper system can be directly emptied, in this way
All modifications can all be removed, since underlying file systems are always maintained at the state of system factory, so passing through bottom document
System can restore factory state.The present invention is specifically modified without paying close attention to application and system, and it is rapid to empty file system operation, from
And system is allow to be promptly restored to the state dispatched from the factory.
Specifically, in the step S1, original file systems are divided into underlying file systems, topmost paper system and table
Layer three level of file system, wherein based on underlying file systems, topmost paper system is superimposed on underlying file systems, table
Layer file system is superimposed upon in topmost paper system.
The present invention is that original file systems are converted to a union file system, and union file system is a lightweight
Hierarchical file system.The present invention mainly by original file systems be divided into lowerdir (underlying file systems)/upperdir (on
Layer file system) three levels of/mergeddir (surface layer file system), wherein by lowerdir (underlying file systems) conduct
Basis, herein on be superimposed upperdir (topmost paper system), ultimately produce mergeddir (surface layer file system).
Union file system (UnionFS) is a kind of layering, lightweight and high performance file system, it is supported to text
Different directories can be mounted to the same virtual file as the primary superposition submitted and come from level to level by the modification of part system
Under system.
Union file system is the basis of Docker mirror image.Mirror image can be inherited by being layered, based on basic mirror
As (there is no father's mirror image), can make various specific using mirror image.In addition, difference Docker container can share some bases
The file system layer of plinth, while oneself exclusive change layer is added, substantially increase the efficiency of storage.
AUFS used in Docker (AnotherUnionFS) is exactly a kind of union file system.AUFS supports to be each
A member directories (branch of similar Git) set read-only (readonly), read-write (readwrite) and write out (whiteout-
Able) permission, while having the concept of a similar layering in AUFS, the branch of read-only authority can be carried out in logic incrementally
It modifies (not influencing read-only part).
Union file system not only can to each catalogue set read-only (Readonly), read-write (Readwrite) and
(Whiteoutable) permission is write, while union file system can also support the mechanism of layering, for example, can be to read-only authority
It is incrementally modified in logic without influencing read-only part part.
Union file system supports the file system being mounted to different directories under the same Virtual File System.It can be with
The Branch of the Branch (branch) of an one Readonly and Writeable is united carry in same file
Under system.
Typical Linux starts to operation and needs two FileSystem (file system), BootFS (guidance file system
System) and RootFS (root file system).
BootFS mainly includes BootLoader (boot loader) and Kernel (kernel), and BootLoader mainly draws
Load Kernel is led, after Boot success, Kernel is loaded into memory BootFS just by Umount (forced unloading).
What RootFS included be exactly in typical linux system /standard directories and the file such as dev ,/proc ,/bin.
RootFS after actuation, is set to Readonly first by Linux, is switched to after carrying out a series of inspections
Readwrite is for users to use.Then the carry Readwrite file system on the RootFS file system of Readonly.
And it is superimposed upwards so that the structure of one group of Readonly and Readwrite constitutes the fortune of a Container (container)
Column catalogue, each be referred to as a file system Layer (layer).
The characteristic of union file system so that each can only be present in the modification of Readonly layers of file/directory
In the Writeable layer on upper layer.In this way since there is no competition and also multiple Container can share Readonly file
System layer.Generally speaking for Container, entire RootFS becomes read-write, but in fact all modifications
It is all written in the writeable layer of top layer, image does not save User Status, can be used for template, reconstruction and duplication.
The present invention also exactly realizes the setting of three layers of file system using above-mentioned union file system.
In the step S2, using surface layer file system as final mount directory, carried out when to surface layer file system
When modification, change is stored in topmost paper system.
In above-mentioned union file system, surface layer file system is final mount directory, i.e. the operation of user is all in table
It is operated in layer file system, when user modifies to surface layer file system, change (i.e. modification content) is stored in
In topmost paper system, but not directly operate lowerdir (underlying file systems).Underlying file systems therein are mainly
For saving system file, such as operating system physical file.
In the present invention, underlying file systems are the file system of operating system physical file, and topmost paper system is conduct
The file system of system modification gets out mergeddir (surface layer file system) by union file system, operating system is transported
File system when row is switched to mergeddir (surface layer file system).
It further, include the behaviour of system update and user to surface layer file system to the modification that surface layer file system carries out
Make.The content that i.e. topmost paper system is saved is mainly system update content and user's operation data.
By aforesaid operations, during operating system, the data such as system update, user's operation can be all stored in
Upperdir (topmost paper system), and the file system lowerdir (underlying file systems) where operating system physical file
Never it is modified.
In the step S3, when needing to reset original file systems, topmost paper system is emptied, and pass through
Underlying file systems factory reset.
When operating system (original file systems) occurs needing the case where resetting, upperdir file system is directly emptied
(topmost paper system), modifications all in this way can all be removed, and be since lowerdir (underlying file systems) is always maintained at
The state of system factory, to realize recovery factory state.
Further, when emptying topmost paper system, while surface layer file system is emptied, surface layer file system is not due to relating to
And system physical file, so can equally be purged, it is ensured that factory state can be restored.
Further, when needing to reset original file systems, topmost paper system is emptied, and pass through bottom document
The step of system factory reset, specifically includes:
When needing to reset original file systems, topmost paper system is emptied；
Restart original file systems；
Pass through underlying file systems factory reset.
When carrying out system resetting, topmost paper system can be first emptied, entire original file systems are then restarted, because of bottom
Layer file system be not modified, so can be by underlying file systems come factory reset.
In addition, in system operation, since underlying file systems may change due to uncontrollable
Become, so underlying file systems can be backed up, and the underlying file systems backed up can operate normally, so can lead to
Crossing the underlying file systems of backup, ensure can reset system.
It is currently preferred that underlying file systems are backed up in timing, i.e., backup is primary at regular intervals, such as
A underlying file systems are backed up every other month, it is ensured that underlying file systems are newest file system.
In addition, the last content backed up of covering, the underlying file systems saved are most when being backed up every time
New underlying file systems.
