A file transmission method includes: obtaining file information of a to-be-transmitted file from a distributed coordination node cluster; determining that at least one slave push node stores the to-be-transmitted file according to the file information of the to-be-transmitted file and heartbeat information of the at least one slave push node; wherein the heartbeat information of the at least one slave push node contains file information stored in the at least one slave push node, and the to-be-transmitted file is retrieved by the at least one slave push node from a file storage node cluster; generating a file transmission path, wherein the file transmission path comprises at least one destination node cluster; sending the file transmission path to the at least one slave push node, so that the at least one slave push node sends the to-be-transmitted file to the at least one destination node cluster through the file transmission path.
