Description

[0001] The present invention relates to the field of computer technology, and in particular to a single-node startup method, device, equipment and medium. Background Art

[0002] Currently, with the advent of the new infrastructure era, the demand for cloud deployment and cloud applications is also increasing. Virtualization technology, as the cornerstone of cloud computing, is ubiquitous. The virtualization management system is a platform for integrating underlying resources and is the basis for managing and monitoring virtual resources. Therefore, the performance of the virtualization management system directly affects the performance of the entire system. The deployment form of the virtualization system is also directly related to the performance of the system management module. Customer-site computer rooms are always subject to unstable factors such as power outages and network disconnections. To address the problem of the system being unable to operate normally and provide services after the main node fails, the deployment form of active and standby management nodes has emerged. The basic working principle is that the main node normally provides management node services, and the standby node synchronizes data with the main node. When the main node fails, the standby node can take over the system work, forming a main and standby dual-machine deployment form.

[0003] As can be seen from the above, during the startup of a single node, how to avoid data loss caused by abnormalities in both the primary and backup nodes and improve the stability and security of node operation are problems to be solved in this field. Summary of the Invention

[0008] If the historical main GI tuple information is different from the current main GI tuple information, the first startup information for starting the backup node is sent to the management end; if the historical backup GI tuple information is different from the current backup GI tuple information, the second startup information for starting the main node is sent to the management end, so that the management end uses the received startup information to control the startup of the corresponding node.

[0019] Determine the time range of the previous cycle based on the time range of the current cycle;

[0020] The corresponding historical primary GI tuple information and the historical backup GI tuple information are determined from the local arbitration disk based on the time range of the previous cycle.

[0021] Optionally, determining whether the historical primary GI tuple information of the previous cycle in the local arbitration disk is the same as the current primary GI tuple information, and determining whether the historical backup GI tuple information of the previous cycle in the local arbitration disk is the same as the current backup GI tuple information, includes:

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] In the current context, with the advent of the new infrastructure era, the demand for cloud deployment and cloud applications is growing. Virtualization technology, as the cornerstone of cloud computing, is ubiquitous. A virtualization management system is a platform that integrates underlying resources and serves as the foundation for managing and monitoring virtual resources. Therefore, the performance of the virtualization management system directly impacts the performance of the entire system. The deployment model of the virtualization system is also directly related to the performance of the system management module. Customer-site computer rooms are often subject to unstable factors such as power outages and network disconnections. To address the problem of the system being unable to operate normally and provide services after the primary node fails, the deployment model of active and standby management nodes has emerged. The basic operating principle is that the primary node normally provides management node services, while the standby node synchronizes data with the primary node. If the primary node fails, the standby node can take over system operations, forming an active-standby dual-node deployment. As can be seen from the above, how to avoid data loss caused by failures of both the primary and standby nodes during the startup of a single node and improve the stability and security of node operation are unresolved issues in this field.

[0044] See also Figure 1 As shown, the embodiment of the present invention discloses a single node startup method, which may specifically include:

[0045] Step S11: obtaining and saving in the local arbitration disk the current primary GI tuple information corresponding to the primary node and the current backup GI tuple information corresponding to the backup node in the current cycle.

[0046] In this embodiment, before obtaining and saving the current primary GI tuple information corresponding to the primary node and the current backup GI tuple information corresponding to the backup node in the current cycle in the local arbitration disk, it also includes: creating a logical unit from centralized storage or distributed storage, and establishing a data link between the primary node and the backup node and the logical unit; judging the status of the logical unit, if the status of the logical unit is available, establishing an arbitration disk based on the logical unit and the data link, and formatting the arbitration disk to obtain a local arbitration disk.

[0047] In this embodiment, corresponding IP addresses are added to the primary node and the backup node respectively to obtain the primary IP address and the backup IP address in the storage area network, and then the storage adapter is scanned, and data links are established between the primary node and the backup node and the logical unit based on the primary IP address and the backup IP address respectively.

[0048] Step S12: Determine whether the historical primary GI tuple information of the previous cycle in the local arbitration disk is the same as the current primary GI tuple information, and determine whether the historical backup GI tuple information of the previous cycle in the local arbitration disk is the same as the current backup GI tuple information.

[0049] In this embodiment, it is determined whether the universal unique identifier in the historical main GI tuple information of the previous cycle in the local arbitration disk is the same as the universal unique identifier in the current main GI tuple information, and at the same time, it is determined whether the universal unique identifier in the historical backup GI tuple information of the previous cycle in the local arbitration disk is the same as the universal unique identifier in the current backup GI tuple information.

[0050] Step S13: If the historical main GI tuple information is different from the current main GI tuple information, the first startup information for starting the backup node is sent to the management end; if the historical backup GI tuple information is different from the current backup GI tuple information, the second startup information for starting the main node is sent to the management end, so that the management end uses the received startup information to control the startup of the corresponding node.

[0051] In this embodiment, if the historical main GI tuple information is different from the current main GI tuple information and the historical backup GI tuple information is different from the current backup GI tuple information, then the startup information for starting the main node or starting the backup node or starting the main node and a single backup node at the same time is sent to the management end.

[0052] In this embodiment, the current main GI tuple information corresponding to the master node and the current standby GI tuple information corresponding to the standby node in the current cycle are obtained and saved in the local arbitration disk; it is determined whether the historical main GI tuple information of the previous cycle in the local arbitration disk is the same as the current main GI tuple information, and whether the historical standby GI tuple information of the previous cycle in the local arbitration disk is the same as the current standby GI tuple information; if the historical main GI tuple information is not the same as the current main GI tuple information, the first startup information for starting the standby node is sent to the management end; if the historical standby GI tuple information is not the same as the current standby GI tuple information, the second startup information for starting the master node is sent to the management end, so that the management end uses the received startup information to control the startup of the corresponding node. This application periodically obtains and determines whether the GI tuple information in the arbitration disk is the same, thereby determining the information for restarting the node and sending it to the management end, which can effectively avoid the problem of data loss caused by abnormalities in both the master and standby nodes, and improve the stability and security of node operation.

[0053] See also Figure 2 As shown, the embodiment of the present invention discloses a single node startup method, which may specifically include:

[0054] Step S21: Determine the time range of the current cycle, obtain the current primary GI tuple information corresponding to the primary node and the current backup GI tuple information corresponding to the backup node in the current cycle, and record the corresponding information acquisition time.

[0055] Step S22: writing the time range and the information acquisition time into the current primary GI tuple information and the current backup GI tuple information respectively, and then saving the updated current primary GI tuple information and the current backup GI tuple information to the local arbitration disk.

[0056] Step S23: Determine whether the historical primary GI tuple information of the previous cycle in the local arbitration disk is the same as the current primary GI tuple information, and determine whether the historical backup GI tuple information of the previous cycle in the local arbitration disk is the same as the current backup GI tuple information.

[0057] In this embodiment, before determining whether the historical main GI tuple information of the previous cycle in the local arbitration disk is the same as the current main GI tuple information, it also includes: determining the time range of the previous cycle based on the time range of the current cycle, and then determining the corresponding historical main GI tuple information and the historical backup GI tuple information from the local arbitration disk based on the time range of the previous cycle.

[0058] Step S24: If the historical main GI tuple information is different from the current main GI tuple information, the first startup information for starting the backup node is sent to the management end; if the historical backup GI tuple information is different from the current backup GI tuple information, the second startup information for starting the main node is sent to the management end, so that the management end uses the received startup information to control the startup of the corresponding node.

[0059] In this embodiment, a time range of the current cycle is determined, and current primary GI tuple information corresponding to the master node and current backup GI tuple information corresponding to the backup node within the current cycle are obtained, and the corresponding information acquisition time is recorded; the time range and the information acquisition time are written into the current primary GI tuple information and the current backup GI tuple information, respectively, and then the updated current primary GI tuple information and the current backup GI tuple information are saved to a local arbitration disk; a determination is made as to whether historical primary GI tuple information of a previous cycle in the local arbitration disk is identical to the current primary GI tuple information, and whether historical backup GI tuple information of a previous cycle in the local arbitration disk is identical to the current backup GI tuple information; if the historical primary GI tuple information is different from the current primary GI tuple information, first startup information for starting the backup node is sent to the management end; if the historical backup GI tuple information is different from the current backup GI tuple information, second startup information for starting the master node is sent to the management end, so that the management end uses the received startup information to control the startup of the corresponding node. This application periodically obtains and determines whether the GI tuple information in the arbitration disk is the same, thereby determining the information for restarting the node and sending it to the management end. It can effectively avoid the problem of data loss caused by abnormalities in both the primary and backup nodes, and improve the stability and security of node operation.

[0060] For example, Figure 3As shown, a logical unit is created from centralized storage or distributed storage, and a data link is established between the primary node and the backup node and the logical unit. Then, the status of the logical unit is determined. If the status of the logical unit is available, an arbitration disk is established based on the logical unit and the data link, and the arbitration disk is formatted. The arbitration disk is successfully created to obtain a local arbitration disk. If the data link between the primary node and the backup node and the logical unit is not successfully established or the status of the logical unit is unavailable, the arbitration disk is failed to be created. Hearbeat (heartbeat program) periodically obtains the main GI tuple information corresponding to the master node and the backup GI tuple information corresponding to the backup node based on the arbitration disk startup service mechanism, and determines whether the universal unique identifier in the historical main GI tuple information of the previous cycle in the local arbitration disk is the same as the universal unique identifier in the current main GI tuple information, and at the same time determines whether the universal unique identifier in the historical backup GI tuple information of the previous cycle in the local arbitration disk is the same as the universal unique identifier in the current backup GI tuple information. If the historical main GI tuple information is different from the current main GI tuple information (i.e., A is powered off), then send a message for starting the The first startup information of the backup node is sent to the management end (i.e., starting B). If the historical backup GI tuple information is different from the current backup GI tuple information (i.e., B is powered off), the second startup information for starting the master node is sent to the management end (i.e., starting A); if the historical master GI tuple information is different from the current master GI tuple information and the historical backup GI tuple information is different from the current backup GI tuple information (i.e., A and B are globally powered off), the startup information for starting the master node or starting the backup node or starting the master node and a single backup node at the same time is sent to the management end (i.e., starting A or starting B or starting A and B at the same time).

[0061] For example, Figure 4 As shown, for example, if the update cycle is 15 seconds, 0 seconds to 15 seconds is used as the first cycle range, and the received primary GI tuple information and backup GI tuple information are saved to the arbitration disk. Then 15 seconds to 30 seconds is used as the second cycle, and 0 seconds to 15 seconds is the previous cycle. The arbitration disk path is saved to the / etc / inspur / qdisk file. The arbitration disk saves the universal unique identifier (i.e., the UUID corresponding to 01) in the received primary GI tuple information to the header corresponding to 01, and the GI tuple value in the primary GI tuple information is saved to the data storage corresponding to 01. The universal unique identifier (i.e., the UUID corresponding to 02) in the backup GI tuple information is saved to the header corresponding to 02, and the GI tuple value in the backup GI tuple information is saved to the data storage corresponding to 02.
