Node interaction and protocol identification method and device, equipment and computer medium

The invention relates to a node interaction and protocol identification method and device, equipment and a computer medium, and the node interaction method in a stacking environment comprises the steps: determining a master node in stacking environment engine nodes, and determining the remaining engine nodes in the stacking environment as slave nodes; obtaining configuration information and first protocol identification value data of the master node, and sending the configuration information and the first protocol identification value data to each slave node based on a first preset communication mode; receiving second protocol identification value data sent by each slave node, and storing the second protocol identification value data to a first local cache database; the protocol identification value data in the first local cache database is sent to each slave node based on a first preset communication mode, so that each slave node stores the protocol identification value data to a second local cache database,
