A setup method of a client/server network environment is provided. The client/server network environment includes a controller node and a compute node. The controller node and the compute node are respectively predefined with a specific device function. In the method, a master node recording a plurality of components and a configuration file of each of the components is provided, and an Internet Protocol (IP) address is respectively assigned to the master node, the controller node, and the compute node. When the master node receives a setup request from a device to be set up between the controller node and the compute node, an auto-shell is generated according to the setup request and transmitted to the device to be set up. The auto-shell is executed by the device to be set up to automatically accomplish the setup for realizing the specific device function corresponding to the device to be set up.
