The server resources can be saved by reducing the number of nodes in the test environment, the resources are saved, the cost is reduced, and the normal operation of the test environment is realized.
and S120, when the preset upgrading condition is met, operating the test environment, and switching the user access information to the test environment.
the preset upgrading condition refers to upgrading conditions of the cluster application environment, illustratively, the preset upgrading condition may be that the number of user accesses meets a preset number or at a preset upgrading time point, and the preset number of the number of user accesses may be determined according to the bearing capacity of the test environment; the preset upgrade time point may be determined according to a historical upgrade time point or a historical access record, for example, the user access peak time period may be a time period from 1 to 3 am.
When a preset upgrade condition is met, switching user access information to a test environment, and processing the user access information by the test environment, so that the cluster application environment does not receive the user access information any more, specifically, replacing an IP (Internet Protocol, Protocol for interconnection between networks) address corresponding to a domain name resolution (DNS) address in the user access information with a corresponding server address in the test environment.
it should be noted that before switching the user access information to the test environment, it needs to be determined through testing that the test environment can normally operate, and the user access information can be processed.

on the basis of the above embodiment, the step S230 of switching the user access information to the upgraded test environment may further be:
And the load balancing server receives the user access information, and sends the user access information to the node corresponding to the test environment according to the first preset distribution rule, so that the node processes according to the user access information.
Correspondingly, the step S250 of switching the user access information to the upgraded cluster application environment may also be:
and the load balancing server receives the user access information, and sends the user access information to the node corresponding to the upgraded cluster application environment according to a second preset distribution rule, so that the node processes according to the user access information.
The load balancing refers to that user access information of the same application is uniformly sent to a node corresponding to the application for processing, and the problem that when the user access information is not uniformly distributed, the user access information received by a certain node is too much and exceeds the bearing capacity of the node, so that the user access information cannot be processed in time is solved, or the problem that resources are wasted due to the fact that the certain node does not receive the user access information and is in an out-of-operation state is solved.
In this embodiment, an independent server is provided for load balancing, for example, the load balancing server receives all user access information and uniformly sends the received user access information to the application node for pairing, for example, the load balancing server may send the user access information in a polling sending manner.
