The invention discloses a control node-based shielding information writing method. The method comprises the following steps that various computing node states on a shared storage device are read, wherein each computing node state comprises node state information, process state information and node performance information; whether or not a to-be-monitored virtual machine generates a failure is judged according to the computing node state information; shielding information is written into the shared storage device; and an OpenStack evacuation interface is called to conduct automatic evacuation of the virtual machine. The invention further provides a control node-based shielding information writing device. According to the control node-based shielding information writing method, by setting the shielding information in the shared storage device, automatic shielding of the failed node is achieved through a watchdog device, it is guaranteed that a service is accurately shielded after the node is restarted by using
