Configuration management method and system

The invention provides a configuration management method and system. The method includes that when the configuration data changes, a configuration management module informs a configuration agent module through a message queue module to perform the configuration data update and directly informs a configuration storage module to perform the configuration data update; the configuration agent module receives the updated configuration data sent by the configuration management module through the message queue module and writes the updated configuration data into the shared memory module; the configuration storage module stores the updated configuration data sent by the configuration management module; and the configuration agent module is periodically in data synchronization with the configuration storage module, and the configured data in the configuration storage module is synchronized to the shared memory module. The centralized management configuration items are easy to maintain and the failure due to configura
