Load distributing method, device and server in distributed cache system

The invention discloses a load distributing method, device and server in a distributed cache system, which improves the usability, operating efficiency and stability of the system. The load distributing method of the invention comprises the following steps: filtering a local server node list and generating a temporary server node list, wherein the temporary server node list comprises the information of the server nodes capable of providing services; distributing load weight for all the server nodes in the list according to the state information and/or the load processing capacity of the nodes in the temporary server node list; and generating routing information according to the load weight of each server node, and indicating each server node in the list to update the local routing information.
