Further, in order to ensure the complete upgrading to goal systems and upgrade successfully, in the step S13 described
Before upgrading in upgrade-system environment to the system software, in addition to：Judge root partition in the goal systems
Whether idle storage space meets default system upgrade demand space, if if meeting, to the number in the goal systems
Unloading is carried out according to storehouse.If for example, the default system upgrade demand space for completing the complete upgrading needs to goal systems is
1.3GB, if wherein the idle storage space of the root partition of the goal systems (such as linux system) is 1.8GB, it is seen that described
The idle storage space of the root partition of goal systems meets system upgrade demand space, and in order to ensure having in goal systems
The reservation of some data of importance, it is to avoid lost during system upgrade, thus before read apparatus is upgraded and
It is me to meet system upgrade demand space, and unloading is carried out to the database in goal systems, is realized to the data in goal systems
The data retained are needed to carry out unloading in storehouse, so that sequential reduction is into the database.
Further, before the step S13 in the goal systems database carry out unloading, including：It is based on
Default data storage list, by the corresponding data conversion storage of database in the goal systems into goal-selling path.Need
It is noted that the default data storage list can be when upgrading tool is developed, previously according to target
Running situation statistics carries out management and control and the file and path list that retain the need for obtaining, can also be normal for goal systems
The index list of essential file and catalogue during operation.According to the default data storage list, by the target system
The corresponding data conversion storage of database in system realizes the file and mesh to needing to retain into specified goal-selling path
Record carries out preset in advance reservation, it is to avoid during upgrading to goal systems, and the data for needing reservation are deposited
The generation of the loss problem of data in the corresponding database of storage list.Here, the form of expression of data conversion storage can be supported
The migration of database in Relational DBMS (such as MySQL and sqlite), can also be support dynamic text
The migration of database in part system (such as Zettabyte FileSystem and zpool).
Further, before the step S13 based on default data storage list, by the number in the goal systems
According to the corresponding data conversion storage in storehouse into goal-selling path, including：
According to the type of the database, corresponding database instruction is determined；
It is based on the default data storage list and database instruction, the database in the goal systems is corresponding
Data conversion storage is into goal-selling path.
It should be noted that the type of the database can include but is not limited to be network database (Network
Database), relational database (Relational Database), tree shaped data storehouse (HierarchicalDatabase), face
To object database (Object-oriented Database) etc., wherein, the relational database can for Oracle, DB2,
Sybase, MS SQL Server, Informax and MySQL etc..Different type of database, when being operated to database
The different database instruction of correspondence.
In the embodiment of the application one, before the step S13, in the idle storage for the root partition for judging to obtain goal systems
Space is met after the default system upgrade demand space, according to the type of the database, determines that corresponding database refers to
Data in database are carried out unloading, i.e., according to database instruction, by default data by order according to corresponding database instruction
The corresponding data conversion storage of the corresponding database in goal systems of list is stored into specified goal-selling path.For example,
If the type of the database is mysql databases, it is determined that corresponding database instruction instructs for mysqldump, by this
Data storage list correspondence corresponding in database data exports and are transferred to specify described and preset by mysqldump instructions
In destination path, realize to the file retained the need in goal systems and the reservation in the path of catalogue, it is follow-up right to be also convenient for
Corresponding data are reduced in database, it is to avoid need the data storage list retained corresponding data in database to exist
Goal systems carries out escalation process loss, it is ensured that the security of data.
Because the deployment way in goal systems is varied, to improve the service behaviour of goal systems, by goal systems
It is deployed on the extremely limited DOM cards in space, and the requirement due to aol server to its own system environment is harsh, and it is necessary
Ensure the ability of the upgraded in offline of the goal systems, therefore when upgrading to goal systems, need to be according to the root of goal systems point
The idle storage space in area is judged, to cause the idle storage space for different root partition, carries out different spaces
Operation is handled, to ensure that there is goal systems enough spaces to be upgraded.
In the embodiment of the application one, the free time for judging the root partition in the goal systems before the step S13 deposits
Whether storage space is met after default system upgrade demand space, in addition to：If it is not satisfied, then to being stored in the root partition
Data carry out unloading, until the idle storage space of the root partition meets the default system upgrade demand space.Example
Such as, if the default system upgrade demand space for completing the complete upgrading needs to goal systems is 1.3GB, if wherein the mesh
The idle storage space of the root partition of mark system (such as linux system) is 1.1GB, it is seen that the root partition of the goal systems
Idle storage space is unsatisfactory for system upgrade demand space, in order to ensure have enough idle storage spaces to enter goal systems
Row upgrading, therefore need the data stored in root partition carrying out unloading, to vacate the space of root partition, until the free time of root partition
Memory space disclosure satisfy that the default system upgrade demand space, and then be able to ensure that the root partition of goal systems has foot
Enough idle storage spaces carry out system upgrade.
Further, in order to avoid the goal systems root partition idle storage space threshold value (that is, institute in root partition
Some data are all carried out in unloading or root partition without any data of storage) still it is unsatisfactory for carrying out upgrading needs to goal systems
Default system upgrade demand space, then unloading is carried out to the data that are stored in the root partition before the step S13
Afterwards, in addition to：If the idle storage space threshold value of the root partition is unsatisfactory for the default system upgrade demand space,
Root partition described in prompting user is unsatisfactory for the default system upgrade demand space.If for example, completing to the complete of goal systems
The default system upgrade demand space that whole upgrading needs is 1.3GB, if wherein the goal systems (such as linux system)
(that is, all data are all carried out in unloading or root partition without storage times the idle storage space threshold value of root partition in root partition
What data) be 1.2GB, then need to point out the idle storage space threshold value 1.2GB of the root partition of user's goal systems to be unsatisfactory for
The default system upgrade demand space is 1.3GB, to make user solve to enter the goal systems by way of artificially handling
The problem of default system upgrade demand space required for row upgrading is not enough.Further, if to being stored in the root partition
Data carry out unloading after, it is empty that the idle storage space threshold value of the root partition is unsatisfactory for the default system upgrade demand
Between, then need the data convert stored in the root partition by unloading into root partition, it is to avoid the data stored in root partition are lost
Lose, the idle storage space threshold value that user's root partition is reresented afterwards is unsatisfactory for default system upgrade demand space.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgrading
Success, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Deletion is embedded in institute
State the upgrade-system environment in goal systems.In order to reduce the risk upgraded to goal systems, therefore in target system
Embedded upgrade-system environment in system, the program upgraded for running to goal systems is simultaneously soft to the system in goal systems
Part is upgraded, and to avoid influencing each other between the program and system software for upgrading, is upgraded to goal systems
After success, the upgrade-system environment that need to be embedded in the goal systems is deleted, to save the storage resource of goal systems.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgrading
Success, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Based on described default
Data storage list and the goal systems that is transferred under the goal-selling path in the corresponding data of database, it is right
The database is recovered.If here, data storage list file essential when normally being run for goal systems
With the index list of catalogue, for example, the recovery to living document system, especially to the corresponding storage pool of living document system
Recover, because living document system is during being upgraded, can cause to be built in the corresponding storage pool of living document system
Vertical file system failure, therefore need according to living document system dependent instruction, data storage list correspondence is transferred to default
Data recovery in destination path is realized to protecting the need in goal systems into the corresponding storage pool of living document system
The file stayed and the reservation in the path of catalogue, based on data storage list and can correspond to the goal-selling path of unloading rapidly
Find the data of unloading, additionally it is possible to accurately and quickly by the data recovery of unloading into goal systems.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgrading
Success, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Based on described default
Data storage list, database instruction and the goal systems that is transferred under the goal-selling path in database pair
The data answered, recover to the database.Here, if desired recovering to the mysql databases in goal systems, then
It is pre- based on this when the data in the database are recovered, it is necessary to call the corresponding database instruction of mysql databases
If data storage list, will be in the goal systems that be transferred under goal-selling path before carrying out system upgrade should
The corresponding data of mysql databases, are imported and to the mysql databases, to realize the mysql databases of goal systems
In the need for the data that retain recovered.
Further, the step S13 upgrades in the upgrade-system environment to the system software, if upgrading
Success, then switch to after its own system environment upgrades to the nonsystematic software, in addition to：Based on the data
List is stored, data scrubbing is carried out to its own system environment of the goal systems.Produced to remove in escalation process
Raw file abnormal residual, will be described based on the corresponding file of the data storage list for needing to retain and the path of catalogue
It is all in addition to the path of the corresponding file of the data storage list and catalogue in its own system environment of goal systems
Data dump, and then the abnormal residual of the uncontrolled file in its own system environment of goal systems will be entered in escalation process
Row cleaning, it is ensured that the controllability and security of its own system environment of goal systems, and save the storage resource of goal systems.
In summary, in a kind of method for upgrading system that the application is provided, during in order to upgrade to goal systems, it is considered to
To goal systems its own system environment the bottom software and file system of the goal systems of itself are upgraded during,
Influenceed by its own system environment, in some instances it may even be possible to the machine of delaying can be caused, therefore before upgrading to the goal systems, in the mesh
An embedded upgrade-system environment in mark system, so that the ROMPaq needed for upgrade-system can be in the upgrade-system environment
Run, its own system environment separation of upgrade-system environment and goal systems is opened so that the upgrading of whole escalation process
Program is run in the case where departing from its own system environment, and then is no longer influenceed by its own system environment, can be completely free of liter
Interactional limitation between upgrade-system environment and its own system environment where level program operation, is reduced to target system
The risk united during being upgraded.
Then above-described embodiment, in order to ensure the integrality upgraded to goal systems, before being upgraded, is also needed
Judge whether the idle storage space of the root partition of goal systems meets default system upgrade demand space, if if meeting,
The database retained needing system to need carries out unloading, and default data storage list is corresponding in goal systems
The corresponding data conversion storage of database into specified goal-selling path, if if being unsatisfactory for, by what is stored in root partition
Data carry out unloading, until the idle storage space of root partition meets the default system upgrade demand space of upgrading needs, if
Data conversion storage in root partition is finished, default system upgrade demand space is still unsatisfactory for, then by all numbers of unloading
According to being restored in root partition, and the default system upgrade demand for pointing out user's root partition to meet system upgrade demand is empty
Between.
Then above-described embodiment of the application, the corresponding data in goal systems is stored in the corresponding database of list
Data are carried out after unloading, run ROMPaq in the upgrade-system environment, to the system software in goal systems (for example
Kernel software in inner nuclear layer, file system and structured file etc.) upgraded, after the completion of upgrading to system software,
By changing after boot manager (grub configurations), the goal systems is restarted, the grub configurations are by escalation process from described
Switched in upgrade-system environment in its own system environment, to realize the switching to upgrade-system environment and its own system environment,
And nonsystematic software (such as application software package) is upgraded in its own system environment, and by data storage list
The corresponding data convert being transferred under the goal-selling path specified will remove data storage list into corresponding database
Outside all data carry out cleaning deletion, while the embedded upgrade-system environment is deleted, to save goal systems
