Rule synchronous processing method and system, rule server and gray server

The invention discloses a rule synchronous processing method. The method comprises the steps of setting a first monitoring thread for monitoring a rule server, wherein the first monitoring thread is used for receiving gray rule change information; after change information that a gray rule in the rule server is changed is received according to the first monitoring thread, regenerating rule configuration file information corresponding to the change information in a rule mode required by a gray system; and after the rule configuration file information is generated successfully, carrying out automatic starting, thereby enabling the rule configuration file information to take effect. The invention also discloses a rule synchronous processing system, the rule server and a gray server. The problem that in related technologies, after a gray release system makes a distribution rule of a rear end service server, the rule needs to be manually configured by operation and maintenance staff is solved. The gray rule in the
