Method and device for managing configuration parameters

The invention discloses a configuration parameter management method and device. The method comprises the steps that a first application node obtains an uploading instruction; in response to the uploading instruction, sending a downloading instruction to the second application node; the downloading instruction is used for indicating the second application node to be switched to a downloading state; the first application node is switched to an uploading state; and after determining that the configuration parameters of the first application node are updated, sending the updated configuration parameters to the second application node to indicate the second application node to load the updated configuration parameters. Wherein the first application node is any application node in the micro-service architecture; the second application node is any application node except the first application node in the micro-service architecture; the downloading state indicates that the second application node allows to load the c
