The invention discloses an online activation or recovery method based on a Linux operating system. The method specifically comprises the steps that S1, an online activation or recovery device is constructed, wherein a KMS server side and a KMS client side are in communication connection with an MQTT broker through an MQTT protocol; s2, the KMS client side sends a registration message to the MQTT broker; s3, the KMS server side receives the registration message from the MQTT broker and responds to the MQTT broker; s4, the KMS client receives an activation or recovery message sent by the KMS server through the MQTT broker; or the KMS client actively sends an activation or recovery message to the KMS server through the MQTT broker. According to the method, the authorization information can be managed and controlled in a centralized manner, one-key batch activation/recovery operation of the operating system can be realized, authorization use is more flexible, and meanwhile, the problem that large-batch machine ac
