Embodiments of the present invention disclose a method for configuring a resource and an apparatus. The method includes: allocating a system resource to a currently active application sub-scenario in an application according to recorded system resource occupation information of the application sub-scenario of the application, where the system resource occupation information of the application sub-scenario of the application includes the system resource occupation information recorded when the application sub-scenario works in a process of testing the application after the application sub-scenario of the application is defined. With the present invention, the system resource is configured for the application sub-scenario at a single attempt. Therefore, enough system resources are ensured to meet the requirements for running the currently active application sub-scenario of the application, the running performance is ensured, and the adjustment time and the power consumption are saved.
