Example 1

Fig. 1 is a flowchart of a database exercise environment construction method according to a first embodiment of the present invention, where the method may be applied to the case of automatically constructing a database exercise environment of a distributed database, and the method may be performed by a database exercise environment construction device, where the database exercise environment construction device may be implemented in a form of hardware and/or software, and the database exercise environment construction device may be configured in an electronic device. As shown in fig. 1, the method includes:

S110, determining a standby management area of a database cluster to be exercised in a distributed database; the standby management area comprises a plurality of functional component nodes under the database cluster to be exercised.

Wherein the distributed database may comprise at least one database cluster. The database cluster to be exercised may be a database cluster to be subjected to business exercise. The database cluster to be exercised can comprise at least one functional component node, and different functional component nodes can execute different service functions. For example, the functional component node may be a data node or a computing node, etc.

Wherein, the database cluster to be exercised can have a main management area and a standby management area. When the regional node of the main management region fails or is abnormal, the regional node of the standby management region can process service data. Therefore, the exercise environment can be built in the standby management area, for example, an exercise platform can be built, and the availability of each functional component node in the standby management area is verified. Before component availability verification can be performed, an automated build or construction of the exercise environment needs to be performed in the standby management area.

For example, the standby management area to which the database cluster to be exercised in the distributed database belongs may be determined by the exercise server. The to-be-exercised cluster can be selected by related technicians according to actual requirements, and the standby management area to which the to-be-exercised database cluster belongs can be automatically determined by the exercise server according to the deployment information of the to-be-exercised database cluster related cluster. The drill server may be a host device deployed within the standby management area. There are multiple functional component nodes under the database cluster to be exercised in the standby management area, and the number of the functional component nodes with different component function types can be one or more. Component function types of the function component nodes may include data function types, computation function types, and the like. For example, if there are data nodes and computing nodes in the cluster to be exercised, the standby management area may include at least one functional component node of a data function type and at least one functional component node of a computing function type.

S120, selecting a main node of the component to be exercised and a slave node of the component to be exercised from the functional component nodes.

The functional component nodes are different in component function types, at least one functional component node can be selected from the functional component nodes of different component function types to serve as a component node to be drilled, any component node to be drilled is randomly selected from the component nodes of the same component function type to serve as a main node of the component to be drilled in the component function type, and other functional component nodes are slave nodes of the component to be drilled in the component function type.

Specifically, if the component function type a and the component function type B exist in the standby management area, the component function type a includes a functional component node A1, a functional component node A2 and a functional component node A3; component function type B includes a function component node B1, a function component node B2, a function component node B3, and a function component node B4. The preset number of functional component nodes can be selected from the functional component nodes of the component functional types respectively to serve as component nodes to be exercised. The preset number can be preset by related technicians according to actual requirements, and the preset number corresponding to the function types of different components can be the same or different. For example, the preset number of the component function types a may be set to 2, the preset number of the component function types B may be set to 3, and the component nodes to be exercised selected randomly under the component function types a are the function component node A1 and the function component node A2 correspondingly; the component nodes to be exercised selected randomly under the component function type B are a functional component node B1, a functional component node B3 and a functional component node B4. After random selection, the main node of the component to be exercised of the component function type A can be determined to be the functional component node A1, and the slave node of the component to be exercised is the functional component node A2. After random selection, the main node of the component to be exercised of the component function type B can be determined to be the functional component node B3, and the auxiliary nodes of the component to be exercised are the functional component node B1 and the functional component node B4.

S130, constructing an exercise management node for managing node related information of a to-be-exercised component master node and a to-be-exercised component slave node.

The exercise management node is used for managing node related information of the to-be-exercised component master node and the to-be-exercised component slave node. For example, node status, node alert information, etc. of the component nodes to be exercised may be collected and stored.

For example, the exercise server may construct an exercise management node on its own server, and the component master node to be exercise and the component slave node to be exercise point to the exercise management node.

And S140, establishing link connection among the exercise management node, the to-be-exercised component master node and the to-be-exercised component slave node to obtain a link connection establishment result.

For example, the component configuration addresses of the component master node to be exercised and the component slave node to be exercised may be updated to the management node address of the exercise management node; the main node of the component to be exercised and the auxiliary node of the component to be exercised can establish link connection with the exercise management node based on the updated component configuration address, and a link connection establishment result is obtained. The link connection establishment result may include connection establishment success and connection establishment failure, among others.

S150, determining the construction result of the drilling environment of the database cluster to be drilled of the distributed database according to the link connection construction result.

For example, if the link connection establishment result is that the connection establishment is successful, the exercise environment of the database cluster to be exercised of the distributed database is successfully established; if the link connection establishment result is connection establishment failure, the construction of the exercise environment of the database cluster to be exercised of the distributed database fails.

Example two

Fig. 2 is a flowchart of a database exercise environment construction method according to a second embodiment of the present invention, where the present embodiment is optimized and improved based on the above technical solutions.

Further, the step of selecting a main node of the component to be exercised and a slave node of the component to be exercised from the functional component nodes is performed to 'refine' to determine the component function types of the functional component nodes; selecting a component node to be exercised from all the functional component nodes belonging to the same component function type according to the node information of all the functional component nodes; and determining a to-be-exercised component master node and a to-be-exercised component slave node in each to-be-exercised component node with the same component function type. The selection mode of the main node of the component to be exercised and the slave node of the component to be exercised is perfected.

Further, the link connection among the drilling management node, the main node of the component to be drilled and the slave node of the component to be drilled is established in the step, and the link connection establishment result is obtained and is refined into the management node address of the drilling management node, and the node link address of each node of the component to be drilled is updated; and each component node to be exercised establishes a link connection with the exercise management node based on the node link address to obtain a link connection establishment result. In order to perfect the determination of the link connection establishment result. In the embodiments of the present invention, the descriptions of other embodiments may be referred to in the portions not described in detail.

As shown in fig. 2, the method comprises the following specific steps:

s210, determining a standby management area of a database cluster to be exercised in a distributed database; the standby management area comprises a plurality of functional component nodes under the database cluster to be exercised.

S220, determining the component function type of each functional component node.

The component function types of the function component node may include a data function type, a calculation function type, a global transaction management function type, and the like.

S230, selecting the component node to be exercised from all the functional component nodes belonging to the same component function type according to the node information of all the functional component nodes.

Wherein the node information may include node identification information, which may characterize node uniqueness of the functional component node. For example, the node identification information may be a node identification serial number, and is composed of a character string.

For example, the component node to be exercised may be selected from the functional component nodes belonging to the same component function type according to the node identification information of the functional nodes. Specifically, node identification serial numbers of all function component nodes of the same component function type are sequentially ordered from high to low according to the size of four bits after the serial numbers, and the function component node with the top three bits of the serial numbers is selected as a component node to be exercised under the component function type. The sequence number ordering rule and the number of bits for selecting the ranking can be preset by related technicians according to actual requirements.

In an alternative embodiment, the node information includes node address and node port information; correspondingly, according to the node information of each functional component node, selecting the component node to be exercised from all functional component nodes belonging to the same component function type, including: determining whether functional component nodes with the same node address exist in all the functional component nodes with the same component function type; if yes, determining the component node to be exercised in all the functional component nodes with the same component function type according to the node port information of the functional component nodes with the same node address.

Illustratively, determining whether there are functional component nodes with the same node address among the functional component nodes of the same component function type; if yes, determining node port information of the same functional component node; if not, the function component nodes with preset numbers can be selected from the function component nodes with different node addresses at will to be used as the component nodes to be exercised under the component function types. If the functional component nodes with the same node address exist, node port information of the same functional component nodes is determined, functional component nodes with the same node address are ordered based on the port information and a preset ordering rule, and the functional component nodes positioned at the head or tail of the ordering are selected to serve as component nodes to be exercised with the same node address, so that the component nodes to be exercised with the same node address are respectively obtained, and further the component nodes to be exercised with the component function type are obtained.

According to the method, the device and the system for selecting the component nodes to be exercised, the component nodes to be exercised are selected in a mode of combining the node addresses and the node port information of the functional component nodes, the targeted selection of the component nodes to be exercised is achieved, and the characteristics of the component nodes are combined, so that the construction of the exercise environment is more real.

S240, determining a to-be-exercised component master node and a to-be-exercised component slave node in each to-be-exercised component node with the same component function type.

For example, any component node to be exercised can be randomly selected from the component nodes to be exercised with the same component function type as a main node of the component to be exercised with the corresponding component function type, and other component nodes to be exercised with the component function type are determined as slave nodes of the component to be exercised with the component function type.

In an alternative embodiment, determining the to-be-exercised component master node and the to-be-exercised component slave node in the to-be-exercised component nodes with the same component function type includes: determining the node data quantity of each to-be-exercised component node; and determining a to-be-exercised component master node and a to-be-exercised component slave node in each to-be-exercised component node with the same component function type according to the node data quantity.

The node data size can be the size of the data size synchronized or processed in the node of the component to be exercised.

In the exemplary embodiment, in the component nodes to be exercised with the same component function type, the component master node with the largest node data volume may be selected from the component nodes to be exercised, and the other component nodes to be exercised are used as the component slave nodes to be exercised with the corresponding component function types, so as to obtain the component master node to be exercised and the component slave node to be exercised with the component function types.

The node characteristics of the master component node and the slave component node are considered in the optional embodiment, and accurate selection of the master node and the slave node of the component to be drilled in the component nodes to be drilled with the same component function type is realized.

S250, constructing an exercise management node for managing node related information of a to-be-exercised component master node and a to-be-exercised component slave node.

And S260, updating the node link address of each component node to be exercised by adopting the management node address of the exercise management node.

It should be noted that, the original node configuration address of each component node to be exercised may be a management node address pointing to the main management area of the database cluster to be exercised.

The original node configuration address of each component node to be exercised is updated by using the management node address of the exercise management node, so as to update the node link address of each component node to be exercised, that is, the updated node link address of each component node to be exercised is the management node address of the exercise management node.

S270, each component node to be exercised establishes link connection with the exercise management node based on the node link address, and a link connection establishment result is obtained.

Illustratively, each node to be exercised establishes link connection with the exercise management node based on the node link address, and a link connection establishment result is obtained. The link connection establishment result comprises connection establishment success and connection establishment failure.

S280, determining a construction result of the drilling environment of the database cluster to be drilled of the distributed database according to the link connection construction result.

According to the technical scheme of the embodiment, the component function types of the functional component nodes are determined, the component nodes to be drilled are selected from the functional component nodes belonging to the same component function types according to the node information of the functional component nodes, and the component master node to be drilled and the component slave node to be drilled in the component nodes to be drilled of the same component function types are determined, so that the accurate determination of the component master node to be drilled and the component slave node to be drilled is realized. By adopting the management node address of the exercise management node, the node link address of each component node to be exercised is updated, and each component node to be exercised establishes link connection with the exercise management node based on the node link address, so that a link connection establishment result is obtained, and accurate determination of the link connection establishment result is realized.

After the construction of the exercise environment of the database cluster to be exercised is completed and the construction is successful, the availability of the master node of the component to be exercised and the slave node of the component to be exercised can be verified.

In an alternative embodiment, after obtaining the link connection establishment result, if the link connection establishment result is that the connection establishment is successful, sending a task execution instruction to the to-be-exercised component master node, and executing the task execution instruction by the to-be-exercised component master node to obtain a task instruction execution result; and verifying the availability of the components of the main node of the component to be exercised according to the execution result of the task instruction.

The task execution instruction may be any execution instruction, for example, may be a data addition instruction, a data deletion instruction, a data modification instruction, or a data search instruction of a database.

The task execution instruction is executed after the main node of the component to be exercised receives the task execution instruction, so as to obtain a task instruction execution result. The task instruction execution result may include success of task execution and failure of task execution. If the task execution is successful, the component availability verification of the component master node to be exercised can be indicated to pass; if the task execution fails, the component availability verification of the component master node to be exercised can be indicated to be failed.

In an alternative embodiment, if the task instruction execution result is that the instruction execution is successful, the slave node of the component to be exercised synchronizes task data generated in the process of executing the task execution instruction by the master node of the component to be exercised, so as to obtain a data synchronization result; and verifying the availability of the components to be exercised from the node according to the data synchronization result.

For example, in the process that the main node of the component to be exercised executes the task, task data are generated, and the slave node of the component to be exercised synchronizes the task data generated in the process that the main node of the component to be exercised executes the task in real time, so that a data synchronization result is obtained. If the data synchronization result is successful in data synchronization, the fact that the component availability verification of the to-be-exercised component slave node passes can be indicated; if the data synchronization result is a data synchronization failure, the component availability verification of the component slave node to be exercised is not passed.

After the exercise environment is set up and the exercise is completed, the environment can be restored to the original environment.

For example, after determining the component nodes to be exercised, metadata of each component node to be exercised may be migrated to the exercise management node, where a time of recording the current migrated data is a start time. And when the environment is restored, restoring the component node to be exercised to the state of the starting moment. Specific recovery modes can be two, rollback gtid (global transaction identifiner, global transaction identifier) and backup recovery modes. If the business contains DDL during drilling, only a backup recovery mode can be adopted, backup is performed firstly during construction, and backup files are used for recovery during recovery. Then, the drilling management node is temporarily used for cleaning metadata of the drilling management console. And finally, the pointing direction of the component node to be exercised is returned, and the address of the exercise management node pointed in the component node configuration file to be exercised is restored to the address of the management console of the original production environment.
