The invention discloses a request processing method and device based on a server cluster and a medium, the method comprises the steps that the method is applied to a processing system, the processingsystem comprises a client and the server cluster, and the method comprises the steps that the server cluster receives a first request sent by the client and routes the first request to a first serviceterminal; the first service terminal performs corresponding processing on the first request and writes a corresponding processing result into a persistence layer after the processing is finished; theservice terminal cluster receives a second request sent by the client, and routes the second request to a second service terminal when the first service terminal is in an abnormal state; and the second service terminal acquires a processing result in the persistence layer, and correspondingly processes the second request based on the processing result. Even if the first service terminal crashes,the second service terminal can obtain the processing result in the persistence layer. When the second service terminal processes the second request, the client does not need to execute the operationbefore the crash again, and the second service terminal can process the second request, so that the availability of the system is improved, and the user experience is also improved.
Description
Technical field[0001]This application relates to the field of server clusters, and in particular to a request processing method, device and medium based on server clusters.Background technique[0002]Modern server / client mode (Server / Client, C / S) or browser / server mode (Browser / Server, B / S) In order to meet the simultaneous use of a large number of users, the server usually adopts the cluster mode, and the cluster contains multiple The server node provides services for each client at the same time.[0003]In cluster mode, if you want to provide stateful services, sticky sessions are generally used, that is, after a client's first request is routed to a server node, its subsequent requests will be routed to the same node. If a server node crashes in the process of processing a client request, the next request of the client will be routed to an available new node. However, because the previous request has not been processed on the new node, the status is inconsistent with the client, and ...
