The application relates to the technical field of network security, and discloses a certificate adaptive degradation scheduling and renewal method and system based on an ACME renewal information protocol, which is used for solving the technical problems of low automation degree and poor renewal management effect of a certificate renewal method in the prior art. The method comprises the following steps: maintaining an independent scheduling state for each certificate; wherein the scheduling state at least comprises a next check time and a scheduling level; judging whether the check process of a target certificate is triggered according to the next check time; when the check process of the target certificate is triggered, corresponding processing strategies are executed based on the scheduling level of the target certificate; if the execution fails, the scheduling level of the target certificate is switched based on the error type at the time of failure, and the next check time is updated; if the execution succeeds, a renewal time is obtained according to the scheduling level at the time of successful execution; and the ACME certificate issuing process is triggered based on the renewal time to realize automatic renewal.

The invention provides a distributed lock renewal method, system, device and product. The distributed lock renewal method comprises the steps of obtaining historical renewal time consumption of task execution of a distributed lock; calculating the renewal time interval of the distributed lock by using the historical renewal time consumption, the basic time interval and the dynamic adjustment rule; and sending a renewal request to database equipment according to the renewal time interval obtained by calculation so as to complete renewal before the distributed lock expires.
