Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
The installation method of the patch of the embodiment of the present invention adopts a point storehouse principle, divide storehouse to process rpm database, and reconstruct and install, smoothly install and can carry out in different CPU core, be i.e. multi-core parallel concurrent, make full use of system computing capacity, accelerate the speed of the installation of patch.And when occurring abnormal in patch installation process, can walk abreast rollback in multinuclear, make system mend get back to installation before state.
Fig. 1 is the process flow diagram of the installation method of embodiment of the present invention patch, and as shown in the figure, the present embodiment specifically comprises the steps:
Step 101, utilizes rpm database generate reconstruct rpm database and install rpm database;
A point storehouse process was carried out before concrete installation patch, namely the rpm database of copy system is needed, there are two rpm databases in such system, portion is called reconstruct rpm database for reconstructing lowest version rpm database, and a update highest version rpm database that is used for is called installation rpm database in addition;
Step 102, is encapsulated as patch by the rpm in rpm database, patch is encapsulated as service packs;
Because be surrounded by the structural requirement of certain patch for installed patch based on the parallel installation method of the multinuclear patch in point storehouse, Fig. 2 is the analytic structure schematic diagram of patch, as shown in the figure, service packs patchs is the set of a series of patch patch.
The analytic structure of Patchs comprises installs list install.list, single service packs patch1...patch n, service packs configuration information patchs spec.
Single patch is the encapsulation to rpm bag in essence, and the structure elucidation of single patch patch comprises: configuration information patchspec and hooks of the list of rpm packet archive, rpm APMB package filelist, patch of encapsulation.And hooks guarantees rpm profile data integrality, the hooks script that user writes, when follow-up level and smooth installation, ensures the integrality of data.
For the rpm packet in rpm database, must carry out encapsulation can follow-up parallel installation, is made patch file, then multiple patch integrating documents is become single patchs file so first single rpm is packed.
Step 103, according to the current rpm identification code in the installation list in service packs, is reconstructed corresponding current rpm packet in reconstruct rpm database;
In order to meet user's patch can rollback rpm database to arbitrary version, to need before upgrading backup the database of rpm patch is installed.
Step 104, according to current rpm identification code, installs installing current rpm packet corresponding in rpm database; And according to next rpm identification code of installing in list, next corresponding rpm packet in reconstruct rpm database is reconstructed;
Step 105, by the smoothing installation of current rpm packet after installation; And according to next rpm identification code, install installing next rpm packet corresponding in rpm database; And according to next rpm identification code again of installing in list, next the rpm packet again in reconstruct rpm database is reconstructed, all reconstructs until install all rpm packets that in list, all rpm identification codes are corresponding, install and smoothly install.
Because the update of common rpm packet, easily cause the amended configuration file of user to be covered by the configuration file of highest version, and smoothly install and can perform user's script, can be undertaken seamless for rpm packet update.
Fig. 3 is the schematic diagram processing streamline in the installation method of embodiment of the present invention patch, in order to improve patch installation effectiveness, adopt pipeline processes to carry out patch upgrading, the reconstruct backup-namely described by above-mentioned steps 103-105 installs (upgrading) install-and smoothly installs (upgrading) S_install.
Backup is the previous process of installing patch, for reconstructing the rpm packet of the original lowest version of current system.Installation is the process of upgrade patch, carrys out the original lowest version rpm bag of upgrade-system by the rpm-Uvh of encapsulation.The effect of level and smooth installation is after the complete lowest version rpm of customer upgrade, may there is the situation of user data loss, not lose in order to ensure user configuration information, needs to perform User space script and loses to prevent user profile.
So-called pipeline processes refers to that reconstruct, upgrading, smooth upgrade process are fixed in different IPs and process, realize reconstruct, upgrading, smooth upgrade can the timeslice in different IPs carry out walking abreast while process.Utilize CPU compatibility principle, backup process, install process, S_install process are bundled on different CPU core and are run, reduces the interference of external factor, accelerate patch operating process.
Concrete, the erection sequence of patch processes according to the order of the rpm identification code recording of install.list in patchs bag, namely first process the rpm packet that first rpm identification code in install.list is corresponding, then rpm packet corresponding to second rpm identification code is processed, the rpm packet that to the last a rpm identification code is corresponding.
The meaning of so-called parallel processing is exactly first to reconstruct in rpm database, and first rpm packet that first rpm identification code of install.list is corresponding is reconstructed.
Then will install in rpm database, first rpm packet that first rpm identification code of install.list is corresponding is installed; Meanwhile will reconstruct in rpm database, second rpm packet that second rpm identification code of install.list is corresponding is reconstructed.
Then by first smoothing installation of rpm packet after installation; Meanwhile will install in rpm database, second rpm packet that second rpm identification code of install.list is corresponding is installed; In like manner, also the 3rd corresponding for the 3rd of install.list the rpm identification code rpm packet is reconstructed simultaneously.
In above process, order optimization can be carried out in rpm installation process simultaneously.By that analogy, a time point always there is rpm packet be reconstructed, install and smoothly installing.
Step 106, when installing r pm packet, can be synchronized to the original rpm database of system.
In addition, when the installation of patch, probably have rollback process, the abnormal occurrence such as occurred when system installs patch time, make patch turn back to installation before state, now to multiple steps of rollback also and process of advancing, be similar to installation process, accelerate the speed of rollback.
Fig. 4 is the process flow diagram of the rollback method of the installation method of embodiment of the present invention patch, as shown in the figure, specifically comprises the steps:
Step 201, according to the current rpm identification code in the installation list in service packs, is reconstructed corresponding current rpm packet in reconstruct rpm database;
Step 202, according to current rpm identification code, carries out rollback by installing current rpm packet corresponding in rpm database; And according to a upper rpm identification code of installing in list, a corresponding upper rpm packet in reconstruct rpm database is reconstructed;
Step 203, by the smoothing rollback of current rpm packet after installation; And according to a upper rpm identification code, carry out rollback by installing a upper rpm packet corresponding in rpm database; And go up a rpm identification code according to installing again in list, the rpm packet of going up again in reconstruct rpm database is reconstructed, until all rpm packets that in installation list, all rpm identification codes are corresponding all reconstruct, rollback peace slides back to and rolls.
The process of the above-mentioned rollback process of the embodiment of the present invention and the process of installation similar, go for that patch is installed abnormal, the scene of such as system reboot and power-off, preserve the installment state of current patch, set install-failed, after system autoboot, the system of rolling back to beats the state before highest version rpm service packs, as described in step 201-201.Namely system rpm packet is in original lowest version rpm bag-like state.And when triggering system installs highest version patchs again, just can according to making it the process of installing this highest version patch in normal state, such as step 101-106.
After the installation method of the patch of the embodiment of the present invention adopts and divides storehouse process, utilize the original rpm database of system to generate reconstruct rpm database and rpm database is installed to operate disparate databases respectively, reconstruct between different patch in such installation list, install, level and smooth installation can parallel processing between different kernel, thus avoid single rpm data library locking, the serialization that the rpm that original rpm database atomicity operates and causes installs, solve the problem that in prior art, the patch upgrading set-up time in enormous quantities is longer, order optimization is carried out to installation process simultaneously, improve patch installation effectiveness, substantially reduce the set-up time of patch in enormous quantities.
For the abnormal occurrence in patch installation process, can parallel rollback be carried out, make system rpm database turn back to patch installing before state.During rollback patch, the rpm database of arbitrary lowest version can be rolled back to, simultaneously to abnormal conditions in patch installation process, there is error handling processing ability.
