Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The core of the present invention is to provide a cloud platform control method, device, equipment and medium to solve the technical problem that the environment before the upgrade is changed from the start of the upgrade to the failure of the upgrade, making it difficult to restore the environment before the upgrade. .

At present, most of the operating systems used by cloud platforms are Linux systems, that is, most of the software provided by cloud platforms to provide services to customers runs on Linux systems. Therefore, the cloud platform control method provided by the present invention is mainly aimed at the Linux system cloud platform. Most of the software packages of Linux systems are in rpm or deb format. Deploying a Linux cloud platform system requires the installation of many software packages. Because the cloud platform has many software packages, each upgrade package may be updated during the system upgrade. If a failure occurs during the upgrade process, the environment before the upgrade has been changed between the start of the upgrade and the failure of the upgrade, resulting in It is very difficult to restore the environment before the upgrade. Based on the above problems, in the method for controlling 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. When it is detected that the cloud platform system upgrade fails, the cloud platform can be updated through the backup data. The corresponding environment is restored when the platform system upgrade fails.

In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Figure 1 is a flow chart of a cloud platform control method provided by an embodiment of the present invention. As shown in Figure 1, the method includes:

S10: Before detecting the upgrade of the cloud platform system, obtain the initial data of each partition of the cloud platform system; back up the initial data of each partition according to the type of stored data in each partition, and obtain the backup data of each partition;

S11: Control the cloud platform system to upgrade and detect the upgrade status of the cloud platform system;

S12: When it is detected that the upgrade status is upgrade failure, use the backup data of each partition to restore the current data of the corresponding partition.

Each partition of the cloud platform system includes the boot partition (/boot partition), /home partition, /swap partition, /root partition, etc. In order to still be able to restore the environment before the upgrade (referring to the data of each partition before the upgrade) after detecting that the cloud platform system upgrade fails, in the embodiment of the present invention, the initial data of each partition is backed up before the cloud platform system is upgraded. . Initial data refers to the data of each partition before the cloud platform system is upgraded.

There is no limit to the backup method, as long as the data can be backed up. Since snapshot backup has the advantage of quickly creating a backup, in the embodiment of the present invention, the snapshot technology is mainly used to back up the initial data, and the backup data is obtained after the backup. It should be noted that the data stored in the boot partition is the kernel and boot files. The boot partition cannot use logical volume management (Logical Volume Manager, LVM) technology. Therefore, if the initial data of each partition is not stored according to the storage data type of the partition, Using different backup processes may result in the inability to back up data in some partitions. Therefore, in the embodiment of the present invention, the initial data of each partition is backed up according to the type of data stored in each partition. After the initial data of each partition is backed up, the backup data of each partition is obtained.

On the basis of backing up the initial data of each partition, the user can issue instructions for controlling the cloud platform system upgrade, control the cloud platform system upgrade according to the upgrade instructions, and then determine the status of the cloud platform system based on the prompt information. The upgrade status of the cloud platform system. The upgrade status of the Izu cloud platform system can be determined through information displayed on the display screen or voice prompts. Specifically, the upgrade status of the cloud platform includes the cloud platform system being upgraded, the cloud platform system being upgraded successfully, and the cloud platform system being upgraded failing. The embodiment of the present invention is a solution proposed for the problem that it is difficult to restore the environment to the environment before the upgrade after the cloud platform system upgrade fails. When the prompt information indicates that the cloud platform system upgrade fails, the corresponding backup data of each partition is used. The current data of the partition is restored. The current data refers to the data of each partition when a cloud platform system upgrade failure is detected. The current data is the data after changes to the initial data. In the process of using the backup data to restore the current data, each current data can be restored with reference to the backup data. However, due to the large amount of data, the efficiency of data recovery is reduced; therefore, in the embodiment of the present invention, the file name is used to restore the current data. The current data is restored. 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 overwritten with the backup data file; when the file name of the backup data file is different from the file name of the current data file, then Directly delete the current data file. After the environment of the cloud platform system that failed to be upgraded is restored to the environment before the upgrade, you can continue to use the previous cloud platform system according to the actual situation, or continue to upgrade the cloud platform system.

The control method of the cloud platform provided by the embodiment of the present invention includes: before detecting the upgrade of the cloud platform system, obtaining the initial data of each partition of the cloud platform system; and performing the initial data of each partition according to the type of stored data of each partition. Back up and obtain the backup data of each partition; detect the upgrade status of the cloud platform system; when it is detected that the upgrade status is upgrade failure, use the backup data of each partition to restore the current data of the corresponding partition. That is, before the cloud platform system is upgraded, the initial data of each partition is backed up. When a cloud platform system upgrade failure is detected, the environment corresponding to the cloud platform system upgrade failure can be restored through the backup data. Since the backup data is obtained by backing up the initial data, the backup data represents the environment before the cloud platform system upgrade. Therefore, the backup data can restore the failed upgrade environment to the environment before the upgrade; in addition, compared with The same backup strategy is adopted for all partitions. In the embodiment of the present invention, the initial data of each partition is backed up according to the type of stored data in each partition, so that the backup method is more in line with the data characteristics of each partition, and some backup methods may not be It is applicable to all types of storage data. For example, snapshot technology cannot be used for backup of boot partitions. It can be seen that the backup method determined according to the type of storage data of the partition provided by the embodiment of the present invention ensures the success rate of data backup as much as possible. .

In order to obtain the partition information of the cloud platform system, you can determine the partitions of the cloud platform system by analyzing the data information of the cloud platform. During the process of collecting partitions, some partitions may be missed, resulting in not all partitions of the cloud platform system being obtained. , so that the data of the missing partition cannot be backed up and restored. Therefore, in some embodiments, before backing up the initial data of each partition according to the type of storage data of each partition, it also includes:

Obtain the files in the cloud platform system used to record all partitions of the cloud platform system and the corresponding mounting directories under each partition;

Determine the partition information of the system disk of the cloud platform system based on the files used to record all partitions of the cloud platform system and the corresponding mounting directories under each partition;

The type of stored data in each partition is determined according to the partition information; the type of stored data at least includes a type of stored boot data, a type of stored user data, and a type of stored data whose storage duration is less than a preset value.

The file used in the cloud platform system to record all partitions of the cloud platform system and the corresponding mounting directories under each partition is usually the system /etc/fstab file. Obtain the corresponding LVM partition through the contents of the file. The partition that stores boot data corresponds to the boot partition, the partition that stores user data corresponds to the /home partition, and the partition that stores data whose storage duration is less than the preset value corresponds to the swap partition.

In the method provided by this embodiment, files used to record all partitions of the cloud platform system and the corresponding mounting directories under each partition are directly read to obtain the partition information of the cloud platform system, so that the file can be used to conveniently and quickly Obtain all partition information of the cloud platform system.

When using LVM snapshot technology to back up the data of each partition, the boot partition cannot be backed up using LVM snapshot technology. In order to enable the backup of the initial data of the boot partition through LVM snapshots and the backup of the initial data of all partitions, in some embodiments, before backing up the initial data of each partition according to the type of storage data of each partition ,Also includes:

Arrange all partitions of the cloud platform system according to the preset backup order;

Backing up the initial data of each partition according to the type of data stored in each partition includes:

Determine whether the type of stored data in the current partition is the type of stored boot data; where the current partition is any partition among all partitions of the cloud platform system;

If not, take a snapshot of the initial data of the current partition to back up the initial data of the current partition;

Since detecting the existence of a partition for snapshot processing, obtain the number of partitions that have been backed up. If it is detected that the number of partitions that have been backed up is less than the number of all partitions, the next partition of the current partition will be used as the new current partition, and Return to the step of determining whether the type of stored data in the current partition is the type of stored boot data; when it is detected that the number of partitions that have been backed up is equal to the number of all partitions, determine that the backup of the initial data of all partitions is completed;

If so, determine that the current partition is the boot partition and obtain the initial data of the boot partition;

Obtain the root partition of the cloud platform system and create a backup directory in the root partition; the backup directory contains the boot directory;

Back up the initial data of the boot partition to the boot directory;

After the detection is completed and the initial data of the boot partition is backed up to the boot directory, snapshot processing is performed on the root partition to back up the initial data of the boot partition; return to the snapshot processing since the detection of the existence of the partition to obtain the number of partitions that have been backed up A step of.

There is no limit to the preset backup sequence and it will be determined based on the actual situation. In addition, since data whose storage duration is less than the preset value is usually temporary data, it is meaningless to back up the partition where it is located. Therefore, in some embodiments, specifically, all partitions of the cloud platform system are backed up in a preset order. Arrangements include:

Obtain the target partition corresponding to the type of data stored in all partitions of the cloud platform system that stores data whose storage duration is less than the preset value;

Get all partitions except the target partition;

Use other partitions as new all partitions of the cloud platform system;

Arrange all new partitions in the preset backup order.

There is no limit to the preset value, which is also determined based on the actual situation. It should be noted that the target partition corresponding to the type of data whose storage duration is less than the preset value is usually the swap partition. The data stored in the swap partition is usually temporary data. The data located in this partition changes. Therefore, the swap does not need to be configured. Back up the data of the partition and back up the initial data of the partition except the swap partition.

In this embodiment, all partitions except the target partition corresponding to the type of data whose storage duration is less than the preset value are backed up, thereby ensuring the effectiveness of the data backup.

In order to clearly understand the snapshot corresponding to each partition, in some embodiments, before performing snapshot processing on the initial data of each partition, it also includes:

Generate a backup configuration file that contains the correspondence between each partition and the snapshot created for each partition; the backup configuration file records the logical volume management and universal unique identification code of each partition, as well as the name and universal uniqueness of the snapshot corresponding to each partition. Identifier;

Place the backup configuration file in the backup directory under the root partition;

Correspondingly, determining the backup data of each partition includes:

Get the information in the backup configuration file;

Restore the logical volume management snapshot to restore the backup data of each partition.

In the method provided by this embodiment, the logical volume management and universal unique identification code of each partition are recorded in the backup configuration file, as well as the name and universal unique identification code of the snapshot corresponding to each partition, and each partition and each partition are recorded in the backup configuration file. There is a corresponding relationship between the snapshots corresponding to the partitions, so that the snapshots corresponding to each partition can be clearly understood based on the corresponding relationships; the backup configuration file is placed in the backup directory of the root partition, so that when the partition is snapshotted, the configuration file will also be backed up at the same time. A backup was made.

Combined with what is described above, the specific process of system backup includes:

1. Before upgrading the Linux system cloud platform, first back up the system data, which mainly involves backup of boot partition data and backup of other LVM partitions, because the boot partition cannot be partitioned using LVM. The boot partition mainly backs up grub boot data, vmlinuz-* and initramfs-* (kernel and boot files). Back up this data to a backup directory on the root partition of the system, and label the backup directory with the version of the current cloud system. Placing the data that needs to be backed up in the boot partition under an LVM partition allows you to back up the data when taking a snapshot. In this way, after the upgrade backup is restored, there is no need to back up again when upgrading again.

2. Read the system/etc/fstab. This file records the current system partition and the corresponding mounting directory. Obtain the corresponding LVM partition through the contents of the file.

3. Generate a configuration file corresponding to the partition to be backed up and the created snapshot. The configuration file records the LVM name and Universally Unique Identifier (UUID) of the backup partition, as well as the name and UUID of the corresponding snapshot. Place it in the backup directory of the root partition so that the backup directory can be saved when taking LVM snapshots.

4. Take separate snapshots of the LVM partitions. When creating the LVM snapshot, the snapshot name snapshot_[partition lv name] will be set for easy identification.

In order to enable those skilled in the art to better understand the system backup method provided by the embodiment of the present invention, the embodiment of the present invention will be further described in detail below with reference to Figure 2 and specific implementation modes. Figure 2 is a flow chart of a system backup method provided by an embodiment of the present invention. As shown in Figure 2, the method includes:

S13: Obtain files recording all partitions of the system;

S14: Full backup/boot partition backup to root partition;

S15: Create a snapshot of the logical volume management partition;

S16: Save the snapshot and corresponding backup partition information.

It should be noted that in step S15, a snapshot is created of the logical volume management partition (non-swap partition).

The process of the backup method is shown in Figure 2. The specific implementation process is as follows:

1. Read the system /etc/fstab. This file records the partitions of the current system and the corresponding mounting directory to obtain the system disk partition information.

2. Create a backup directory in the root partition (/), back up the boot partition, and back up all data under the current boot partition to the boot directory under the backup directory.

3. Take a snapshot of the LVM partition, and name the snapshot in the format of snapshot_[partition lv name].

4. Record the name and UUID of the LVM partition, as well as the name and UUID of the corresponding snapshot, in the backup configuration file in the backup directory.

In the method provided by the embodiment of the present invention, when backing up the initial data, the partition that stores the data type is the type that stores the boot data, that is, the boot partition is backed up separately to the root directory, and then snapshot processing is performed to ensure the booting as much as possible. The data can be backed up successfully, and all partitions are snapshotted, ensuring that the cloud platform system can rely on the backup data to restore to the environment before the upgrade after the upgrade fails.

After detecting a system upgrade failure, the partition is a boot partition. In order to be able to restore the current data, in some embodiments, using the backup data of the boot partition to restore the current data of the boot partition includes:

Obtain the first file corresponding to the backup data of the boot partition and the second file corresponding to the current data of the boot partition;

Compare the first file with the second file;

Obtain the files in the second file whose file names are the same as the file names in the first file, and the files in the second file whose file names are different from the file names in the first file;

Utilize the backup data corresponding to the file in the first file with the same file name in the second file to overwrite the file in the second file with the same file name in the first file, and delete the file in the second file with the same name in the first file. Files with different file names; regenerate the boot configuration file through the boot command to complete the recovery of the current data of the boot partition.

In order to enable those skilled in the art to better understand the system recovery method provided by the embodiment of the present invention, the embodiment of the present invention will be further described in detail below with reference to Figure 3 and specific implementation modes. Figure 3 is a flow chart of a system backup method provided by an embodiment of the present invention. As shown in Figure 3, the method includes:

S17: Read backup configuration file information;

S18: Restore the logical volume management snapshot to restore partition data;

S19: Completely overwrite the existing boot partition data with the boot partition backup data;

S20: Regenerate the boot configuration file.

The system recovery proposed by the invention is shown in Figure 2, and the specific implementation is as follows:

1. When a problem occurs during the cloud platform upgrade, in order to restore the system to the state before the upgrade, the LVM snapshot of the root partition needs to be restored first, because the root partition contains the backup directory. Use LVM's backup and restore command to restore the entire partition to the state at the time of the snapshot.

2. Read the snapshot correspondence configuration file in the backup directory, and then restore the corresponding LVM partition to the snapshot state.

3. Restore the boot partition data, compare the data files in the boot partition, use the files in the backup directory to overwrite the files with the same name in the boot partition, and delete redundant files.

4. Regenerate the boot configuration file through the grub2 command.

5. When restoring to the source system, you can start upgrading again. There is no need to back up again during the upgrade.

In the method provided by this embodiment, when the backup data is used to restore the current data when the system upgrade fails, the current data is restored based on the file name. Compared with the method of directly comparing the current data and the backup data, The method provided by the embodiment of the present invention can greatly improve the efficiency of data backup and replace the entire file data, thus ensuring the accuracy of data recovery.

After using the backup data of each partition to restore the current data of the corresponding partition, it also includes:

Use the restored current data to upgrade the cloud platform system;

After detecting that the cloud platform system upgrade is successful, obtain the backup configuration file in the backup directory;

Delete the snapshot information corresponding to each partition based on the partition information in the backup configuration file and the snapshot information corresponding to each partition;

Delete the backup directory under the root partition.

Figure 4 is a flow chart of a backup and deletion method provided by an embodiment of the present invention. As shown in Figure 4, the method includes:

S21: Read backup configuration file information;

S22: Delete the snapshot of the logical volume management partition;

S23: Delete the backup data of the root directory.

In the backup deletion method provided by the embodiment of the present invention, after the cloud platform upgrade is completed, the backup configuration file in the backup directory is read, and the snapshot and the root partition are deleted according to the backup partition information and corresponding snapshot information in the configuration file. The backup directory below reduces the data generated during the upgrade process and reduces the storage space occupied by the data.

In summary, the embodiment of the present invention backs up the cloud platform system before upgrading and restores it to the pre-upgrade state after the upgrade process fails. This is mainly aimed at cloud platforms that use LVM for disk resource management. Use LVM's snapshot technology to back up the cloud platform before the upgrade. When a failure occurs during the upgrade process, partition recovery is performed through the snapshot of the corresponding partition.
