The embodiment of the invention discloses a cluster control method and a cluster control device. The method can comprise the following steps that a main control terminal receives a host identifier, a host logging code and a host execute command set which respectively correspond to each host computer and are set in a configuration file by a user, wherein the host execute command set which respectively corresponds to each host computer is used for detecting respective running condition of each host computer; the main control terminal transmits a connection request to each host computer corresponding to the host identifier set in the configuration file in parallel; after the main control terminal respectively builds connection with each host computer, the main control terminal transmits the configuration file to each host computer. By the method and the device provided by the invention, the procedure of cluster control can be simplified, the time for a cluster control process is reduced, the aim that main control terminal equipment can simultaneously control a plurality of host computers is fulfilled, and the working efficiency can be greatly improved.
