Centralized configuration method of distributed system based on multicast

The invention discloses a centralized configuration method of a distributed system based on multicast. The centralized configuration method comprises the following steps: a node generates a node identification code; a configuration plug-in set in the node judges whether the node has been set with a configuration center, and if so, the configuration plug-in connects the configuration center according to a set configuration center address; if not, the node sends a broadcast through a multicast group to obtain the configuration center address, and the configuration plug-in connects the configuration center according to the configuration center address obtained by the broadcast; and the configuration center receives configuration request information and the node identification code sent by the node, and sends configuration information applicable to the node to the node according to the configuration request information after verification success by use of the node identification code. According to the centralized
