Wherein the resource pool comprises at least one cloud cache database.
In a specific implementation process, the management and control center can be based on services provided by the MemDB cloud cache database and a ZooKeeper design. The control center provides one or more visual pages (for example, the control center provides two different management console pages for a common user and an operation and maintenance manager respectively), and the user generates a service instance opening instruction in the form of a product instance construction list by operating on the visual pages. Then the management and control center may set up a MySQL database for saving the visualization page data. As shown in fig. 2, the unified access layer may be designed based on keepalive and HaProxy, and then the access service may be a haproxy+keepalive service. The resource pool is composed of cloud cache databases (such as Redis databases) in at least one hardware server, and each cloud cache database can be deployed by selecting the same or different database software versions according to actual needs.

S103, generating a virtual socket corresponding to the service through the management and control center, generating a corresponding relation between the real socket of the service instance node corresponding to the service and the virtual socket corresponding to the service, and configuring the corresponding relation to the access service.
Examples of configuration program code for the Haproxy service and the keepalive service are given below. The specific configuration process can refer to the following program codes and adjust the specific content of each configuration item according to the actual requirement for configuration.
For example, the configuration program code for the Haproxy service is exemplified as follows:
for keepalive services, the configuration program code is exemplified as follows:
after the above-mentioned setting step is completed, as shown in fig. 3, the steps in the service stage include:
s210, receiving a service request of the client to the target service through the access service of the unified access layer.

And S230, returning the cloud cache service data provided by the service instance node to the client through the access service.
Therefore, by the method provided by the embodiment of the invention, aiming at the currently most widely used Redis cloud cache database and the corresponding derived cloud cache database, an access layer is used for facing the client, so that the client is not directly connected with the database of the bottom layer, abstract access to the bottom layer resource node is realized, isolation security of the bottom layer host resource is improved, meanwhile, the client side of the upper layer does not need to care about the specific software version of the cloud cache database of the bottom layer, and suitability of the client side is improved.

and receiving a fault transfer instruction to at least part of service instance nodes through the management and control center.
Therefore, the unified access layer can support data migration operations such as bottom layer resource node switching, transverse expansion and contraction, failover and the like, so that no perception is caused to a client side, convenience in upper layer butt joint is improved, and user experience is enhanced.
Optionally, the service instance node of any service includes a primary service instance node and at least one backup service instance node.
As shown in fig. 4, in step S220, determining, by the access service according to the correspondence between the virtual socket and the real socket, that the service instance node corresponding to the real socket of the target service indicated by the service request is the target service instance node includes:

7. The apparatus of claim 5, wherein the service instance nodes of any service comprise a master service instance node and at least one backup service instance node;
determining, by the access service according to a correspondence between a virtual socket and a real socket, a service instance node corresponding to the real socket corresponding to the virtual socket of the target service indicated by the service request, where the determining includes:
after determining a real socket of a main service instance node corresponding to the virtual socket indicated by the service request according to the corresponding relation between the virtual socket and the real socket through the access service, if the main service instance node corresponding to the real socket is normally accessed, determining that the main service instance node is the target service instance node;
if the main service instance node corresponding to the real socket cannot be normally accessed, determining a real socket of a standby service instance node corresponding to the virtual socket indicated by the service request according to the corresponding relation between the virtual socket and the real socket through the access service, and determining the standby service instance node as the target service instance node.
8. The apparatus of claim 6, wherein the access configuration modification condition comprises at least one of:
receiving a capacity expansion instruction of a service instance node of at least part of services through the management and control center;
receiving a capacity shrinking instruction of a service instance node of at least part of services through the management and control center;
receiving a node switching instruction for at least part of service instance nodes through the management and control center;
and receiving a fault transfer instruction to at least part of service instance nodes through the management and control center.
9. An electronic device, comprising: a processor and a memory for storing instructions executable by the processor;
wherein the processor is configured to execute the instructions to implement the cloud cache database service method of any of claims 1-4.
10. A readable storage medium, characterized in that the readable storage medium stores a computer program, which is used to implement the cloud cache database service method according to any of claims 1-4.
