Data storing method and device for distributed file system

The invention discloses a data storing method and device for a distributed file system and belongs to the network communication field. The method comprises the steps of receiving the file writing request, sent by a client side, of the distributed file system, wherein the file writing request comprises client side identification, distributing a corresponding data node to the file writing request, wherein the distributed data node at least comprises the client side corresponding to the client side identification, and storing file data written by the client side into the data node distributed to the file writing request. The device comprises a receiving module, a distributing module and a storing module. According to the method, the file data written by the client side is stored into the data node of a machine corresponding to the client side, read-write flow generated by the system when files are read and written is reduced, and the read-write speed of the file system, and the operation processing speed of a pr
