Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.
The core of the invention is to provide a control method, a device, equipment and a medium of a cloud platform, so as to solve the technical problem that the environment before upgrading is changed in the process from the start of upgrading to the failure of upgrading, and the environment before upgrading is difficult to recover.
Most of the operation systems used by the cloud platform at present are Linux systems, namely, most of software for providing services for clients by the cloud platform runs in the Linux systems. Therefore, the control method of the cloud platform provided by the invention is mainly aimed at the cloud platform of the Linux system. Most of software packages of the Linux system are in rpm or deb format, and more software packages are required to be installed for deploying a Linux cloud platform system. Because the cloud platform has more software packages, each upgrade package can be updated in the system upgrade process, and for failure in the upgrade process, the environment before the upgrade is changed in the process from the upgrade start to the upgrade failure, so that the environment before the upgrade is expected to be restored is very difficult. Based on the above-mentioned problems, in the control method for the cloud platform provided by the embodiment of the present invention, before the cloud platform system is upgraded, the initial data of each partition is backed up, and after the failure of the cloud platform system is detected, the environment corresponding to the failure of the cloud platform system upgrade can be restored through the backup data.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. Fig. 1 is a flowchart of a control method of a cloud platform according to an embodiment of the present invention, as shown in fig. 1, where the method includes:
S10: before detecting the upgrading of the cloud platform system, acquiring initial data of each partition of the cloud platform system; backing up the initial data of each partition according to the type of the stored data of each partition, and acquiring the backup data of each partition;
s11: controlling the cloud platform system to upgrade and detecting the upgrade state of the cloud platform system;
s12: and under the condition that the upgrading state is detected to be failed in upgrading, recovering the current data of the corresponding partition by using the backup data of each partition.
Each partition of the cloud platform system includes a boot partition (/ boot partition),/home partition,/swap partition,/root partition, and the like. In order to restore the environment before upgrading (refer to the data of each partition before upgrading) after detecting that the cloud platform system fails to upgrade, in the embodiment of the invention, the initial data of each partition is backed up before upgrading the cloud platform system. The initial data refers to data of each partition before the cloud platform system is upgraded.
The backup method is not limited, and data can be backed up. Because snapshot backup has the advantage of quickly creating backup, the embodiment of the invention mainly uses the snapshot technology to backup the initial data, and the backup data is obtained after backup. It should be noted that, the data stored in the boot partition is a kernel and a boot file, and the boot partition cannot use the logical volume management (Logical Volume Manager, LVM) technology, so if different backup processes are not adopted for the initial data of each partition according to the storage data type of the partition, it may result in that the data of some partitions cannot be backed up. Therefore, in the embodiment of the invention, the initial data of each partition is backed up according to the type of the storage data of each partition, and the backup data of each partition is obtained after the initial data of each partition is backed up.
Based on the backup of the initial data of each partition, a user can issue an instruction for representing the control of the upgrade of the cloud platform system, control the upgrade of the cloud platform system according to the upgrade instruction, and then determine the upgrade state of the cloud platform system according to prompt information of the upgrade state of the cloud platform system. The upgrade state of the cloud platform system can be determined through information displayed on a display screen or information such as voice prompts. Specifically, the upgrading state of the cloud platform includes that the cloud platform system is being upgraded, and the cloud platform system is successfully upgraded and fails to be upgraded. The embodiment of the invention provides a solution for the problem that the cloud platform system is difficult to recover to the environment before upgrading after upgrading failure, and the current data of the corresponding partition is recovered according to the backup data of each partition after the upgrading failure of the cloud platform system is prompted in the prompt information. The current data refers to the data of each partition under the condition that the failure of upgrading the cloud platform system is detected. The current data is data after the initial data is changed. In the process of recovering the current data by using the backup data, each current data can be recovered by referring to the backup data, but the data recovery efficiency is reduced due to the larger data volume; therefore, in the embodiment of the invention, the current data is restored based on the file name, and when the file name of the backup data file is the same as the file name of the current data file, the current data file is directly covered by the backup data file; and when the file name of the backup data file is different from the file name of the current data file, deleting the current data file directly. After the environment of the cloud platform system with failed upgrading is restored to the environment before upgrading, the cloud platform system before upgrading can be continuously used according to actual conditions, or the cloud platform system is continuously upgraded.
The control method of the cloud platform provided by the embodiment of the invention comprises the following steps: before detecting the upgrading of the cloud platform system, acquiring initial data of each partition of the cloud platform system; backing up the initial data of each partition according to the type of the stored data of each partition, and acquiring the backup data of each partition; detecting an upgrading state of the cloud platform system; and under the condition that the upgrading state is detected to be failed in upgrading, recovering the current data of the corresponding partition by using the backup data of each partition. The method comprises the steps that initial data of each partition are backed up before the cloud platform system is upgraded, and after the cloud platform system is detected to be failed to be upgraded, environments corresponding to the cloud platform system when the cloud platform system is failed to be upgraded can be restored through the backup data. The backup data is obtained by backing up the initial data, and the backup data represents the environment before upgrading the cloud platform system, so that the environment which fails to upgrade is restored to the environment before upgrading through the backup data; in addition, compared with the method that the same backup strategy is adopted for all the partitions, the method and the system in the embodiment of the invention backup the initial data of each partition according to the type of the stored data of each partition, so that the backup mode is more consistent with the data characteristics of each partition, and some backup modes are possibly not applicable to all types of the stored data, for example, the snapshot technology cannot be used for backup for the boot partition, therefore, the backup mode determined according to the type of the stored data of the partition provided by the embodiment of the invention ensures the success rate of data backup as much as possible.
In order to acquire partition information of the cloud platform system, the partition of the cloud platform system may be determined by analyzing data information of the cloud platform, and in the process of collecting the partition, some partitions may be omitted, so that all the obtained partitions of the cloud platform system are not obtained, and therefore data of the omitted partitions cannot be backed up and restored. Thus, in some embodiments, before backing up the initial data for each partition according to the type of stored data for each partition, further comprising:
acquiring files used for recording all partitions of the cloud platform system and corresponding mounting catalogs under each partition in the cloud platform system;
determining partition information of a system disk of the cloud platform system according to all partitions used for recording the cloud platform system and files of the corresponding mounting catalogs under each partition;
determining the type of the stored data of each partition according to the partition information; the type of the stored data at least comprises the type of the stored guiding data, the type of the stored user data and the type of the data with the stored time length smaller than a preset value.
The files in the cloud platform system for recording all the partitions of the cloud platform system and the corresponding mount directories under each partition are usually system/etc/fstab files. And acquiring a corresponding LVM partition through the content of the file. The partition storing the type of the guide data corresponds to the guide partition, the partition storing the type of the user data corresponds to the home partition, and the partition storing the type of the data with the storage duration smaller than the preset value corresponds to the swap partition.
In the method provided by the embodiment, the files for recording all the partitions of the cloud platform system and the corresponding mounting catalogs under each partition are directly read to acquire the partition information of the cloud platform system, so that all the partition information of the cloud platform system can be conveniently and rapidly acquired through the files.
When the LVM snapshot technology is used for backing up the data of each partition, the LVM snapshot technology cannot be used for backing up due to the fact that the boot partition cannot use the LVM snapshot technology. To enable backup of the initial data of the boot partition, and backup of the initial data of all partitions, by LVM snapshots, in some embodiments, before backup of the initial data of each partition according to the type of stored data of each partition, further comprises:
arranging all partitions of the cloud platform system according to a preset backup sequence;
backing up the initial data of each partition according to the type of the stored data of each partition includes:
judging whether the type of the stored data of the current partition is the type of the stored guide data or not; the current partition is any one partition among all partitions of the cloud platform system;
if not, carrying out snapshot processing on the initial data of the current partition so as to backup the initial data of the current partition;
Starting snapshot processing by detecting that the partition exists, acquiring the number of the partitions which finish backup, taking the next partition of the current partition as a new current partition under the condition that the number of the partitions which finish backup is detected to be smaller than the number of all the partitions, and returning to the step of judging whether the type of the storage data of the current partition is the type of the storage guide data; determining that the backup of the initial data of all the partitions is completed under the condition that the number of the partitions which complete the backup is detected to be equal to the number of all the partitions;
if yes, determining the current partition as a guide partition, and acquiring initial data of the guide partition;
acquiring a root partition of the cloud platform system, and creating a backup catalog in the root partition; wherein, the backup catalog comprises a guide catalog;
backing up initial data of the boot partition to a boot catalog;
after the initial data of the guide partition is detected to be backed up to the guide catalog, snapshot processing is carried out on the root partition so as to backup the initial data of the guide partition; returning to the step of obtaining the number of the partitions which are backed up after the snapshot processing of the partition which is detected to exist.
The preset backup sequence is not limited, and is determined according to actual conditions. In addition, since the data with the storage duration smaller than the preset value is usually temporary data, it is not meaningful to backup the partition where the data is located, in some embodiments, specifically, arranging all the partitions of the cloud platform system according to the preset backup sequence includes:
Acquiring target partitions corresponding to the types of data stored in all partitions of the cloud platform system, wherein the types of the data stored in the data are stored for a time length smaller than a preset value;
acquiring other partitions except the target partition in all the partitions;
taking other partitions as new all partitions of the cloud platform system;
and arranging all new partitions according to a preset backup sequence.
The preset value is not limited, and is also determined according to actual conditions. It should be noted that, the target partition corresponding to the type of the data stored for a duration less than the preset value is typically a swap partition, the data stored under the swap partition is typically temporary data, and the data located in the partition is changed, so that the data of the swap partition may not be backed up, and the initial data of the partitions except the swap partition may be backed up.
In the embodiment, the target partition corresponding to the type except for the data with the storage duration smaller than the preset value in all the partitions is backed up, so that the effectiveness of data backup is ensured.
To clearly understand the snapshot corresponding to each partition, in some embodiments, before snapshot processing is performed on the initial data of each partition, the method further includes:
generating a backup configuration file containing the corresponding relation between each partition and the snapshot created for each partition; the backup configuration file is recorded with a logical volume management and universal unique identification code of each partition, and a snapshot name and universal unique identification code corresponding to each partition;
Placing the backup configuration file in a backup directory under the root partition;
correspondingly, determining backup data for each partition includes:
acquiring information in a backup configuration file;
and recovering the logical volume management snapshot to recover the backup data of each partition.
In the method provided by the embodiment, the logical volume management and the universal unique identification code of each partition, and the names and the universal unique identification codes of the snapshots corresponding to each partition are recorded in the backup configuration file, and the corresponding relationship exists between each partition and the snapshot corresponding to each partition in the backup configuration file, so that the snapshot corresponding to each partition can be clearly known according to the corresponding relationship; the backup configuration file is placed in the backup directory of the root partition, so that the backup configuration file is backed up when the snapshot processing is performed on the partition.
In connection with what is described above, specific processes for system backup include:
1. the method mainly relates to boot partition data backup and other LVM partition backup, and the boot partition cannot use the LVM to partition before upgrading the cloud platform of the Linux system. The boot partition mainly backs up grub boot data, vmlinuz-, and initrimfs- (kernel and boot files). The data is backed up to a backup directory of the root partition of the system, and the backup directory is marked with the version of the current cloud system. The data needed to be backed up of the guide partition is placed under one LVM partition, so that the data can be backed up when snapshot is made, and when the backup is updated again after the backup is restored, the backup is not needed.
2. The system/etc/fstab is read and the file records the partition and corresponding mount directory of the current system. And acquiring a corresponding LVM partition through the content of the file.
3. A configuration file is generated of the correspondence of the partition to be backed up and the created snapshot, the configuration file recording the LVM name and the universally unique identification code (Universally Unique Identifier, UUID) of the backup partition, and the name and UUID of the corresponding snapshot. Placed in the backup directory of the root partition so that the backup directory can be saved when the LVM snapshot is made.
4. And respectively taking snapshots of the LVM partition, and setting the name snapshot_ [ partition lv name ] of the snapshot when the LVM snapshot is created, so that the identification is convenient.
In order to better understand the system backup manner provided by the embodiment of the present invention, the embodiment of the present invention is further described in detail below with reference to fig. 2 and a specific implementation manner. Fig. 2 is a flowchart of a method for system backup according to an embodiment of the present invention, as shown in fig. 2, where the method includes:
s13: acquiring files of all partitions of a recording system;
s14: the full backup/boot partition backs up to the root partition;
s15: creating a snapshot of the logical volume management partition;
S16: and storing the snapshot and the corresponding backup partition information.
