Computing node management method and system

The invention relates to the field of cloud computation, and more specifically relates to a computing node management method and system. The method comprises the following steps: S1, a center server-side receives computing node information sent from a web management interface; S2, the center server-side queries whether a computing node is real and available according to the received computing node information, queries whether record information related to a host corresponding to the computing node is existent in a center database if the computing node is available, and physical information of the computing node is acquired and updated through a livirt interface if the record information is existent, or the step S3 is executed; and S3, the center server-side mounts the stored catalogue on the new computing node, initializes the configuration of the computing node, and acquires and updates the physical information of the computing node by calling the livirt interface. By use of the management method disclosed b
