Specific embodiment
Below with reference to embodiment, the technical schemes of the invention are described in detail.
Gateway server main preparation system restoration methods of the present invention, comprising:
Main uboot program and standby uboot bootstrap are set, while being arranged in master corresponding with main uboot bootstrap
Core and host file system, setting standby kernel corresponding with standby uboot bootstrap and standby file system；
The main uboot bootstrap is set as not being upgraded, flash be it is read-only, the standby uboot bootstrap,
Main kernel and host file system, standby kernel and standby file system are set as to be upgraded；
If device powers down, main uboot bootstrap on startup can school at this time when upgrading standby uboot bootstrap
Whether normal standby uboot bootstrap is tested, if normally, guiding standby uboot bootstrap to start, then guiding in corresponding
Core starting, and load corresponding file system；If abnormal, corresponding kernel is directly guided to start, and load corresponding
File system can upgrade standby uboot bootstrap after the file system starting；No matter uboot standby in this way is guided
Program whether OK, kernel and file system normal boot；
If when upgrading main kernel and host file system, a mark first is arranged to host file system at this time in device powers down
The value of will, the mark is non-zero positive integer, and is saved in flash, after normally upgrading successfully, this mark is understood, by the mark
Value is set as zero；Corresponding uboot bootstrap first judges whether the value of the mark is zero when guiding main kernel, if it is not,
It then proves that host file system powers off in escalation process, causes host file system abnormal, directly guide standby kernel and standby at this time
File system, standby file system normally start；
If device powers down starts main kernel and host file system at this time, main when upgrading standby kernel and standby file system
After file system starting, directly upgrade standby kernel and standby file system.
In the above method, guides standby uboot bootstrap to start, then guide corresponding kernel to start, and load correspondence
File system when, preferentially start main kernel, and load corresponding host file system, if main kernel and host file system are rising
During grade, then restart standby kernel, and load corresponding standby file system.
In the above method, in order to corresponding with zero, as needed, the non-zero positive integer mentioned is preferably 1, or its
His positive integer.Corresponding uboot bootstrap preferentially guides main kernel by main uboot bootstrap when guiding main kernel,
Main kernel can also be guided in case of uboot bootstrap.If having started to standby kernel and standby file system, cannot upgrade at this time standby
Kernel and standby file system, can only upgrade main kernel and host file system.
Embodiment
The embodiment of the present invention is using double uboot bootstrap, dual core+file system mode, that is to say, that uboot
Bootstrap, kernel and file system have a spare tyre, in this example, such as main uboot bootstrap by uboot.img expression,
Standby uboot bootstrap indicates that main kernel is indicated by kernel.img by uboot-bk.img, and standby kernel passes through
Kernel-bk.img is indicated.
The present embodiment is in order to achieve the purpose that make system even if successfully booting up standby system in the case where main system is destroyed
It works normally.Illustrate first:
Main uboot.img can not be upgraded, and flash is read-only；
Standby uboot-bk.img can be upgraded；
Main kernel.img+ host file system: it can be upgraded
Standby kernel.img+ is for file system: can be upgraded.
When practical application:
If 1, upgraded for uboot-bk.img, device powers down, the process that system normally starts is as follows:
If device powers down, main uboot.img can verify standby uboot- on startup at this time in upgrading uboot-bk.img
Whether bk.img is normal；
If normal: if guide standby uboot-bk.img to start, then guide main kernel to start, and load master file system
System；
If abnormal: if directly guide main kernel to start, and load host file system, can be right after host file system starting
Standby uboot-bk.img upgrades；
Though uboot-bk.img standby so whether OK, can ensure file system normal boot.
If 2, upgrading main kernel.img+ host file system, device powers down, the process that system normally starts is as follows:
1) upgrade main kernel.img+ host file system, first set a mark [upg_kernel=to host file system
1], and it is saved in flash, after normally upgrading successfully, removes this mark；
2) uboot first judges the value of upg_kernel in Boot Dernel, if it is 1, proves that host file system is rising
It is powered off during grade, causes system abnormal, directly guide standby kernel.img+ for file system when drawing, standby file system is just
Often starting.
If 3, upgrading standby kernel.img+ for file system, device powers down, starting at this time is main kernel.img+
Host file system after host file system starting, upgrades standby kernel.img+ directly for file system.
If system has started to standby kernel.img+ for file system, cannot upgrade for system at this time standby
Kernel.img+ can only upgrade main kernel.img+ host file system for file system.
Through this embodiment, positive system can just be protected in escalation process, accident power-off can also restore automatically, to prevent returning factory's dimension
It repairs.
