Abstract

The invention provides a method for persistence of Redis data on a cloud platform, which comprises the following steps: s1, creating two redis instances; s2, setting the two redis as a high-availability cluster with a master-slave structure; one redis is a master node and the other is a slave node; s3, closing the data persistence function of the redis on the main node; and S4, opening the data persistence function of the redis from the node. The method for persisting Redis data on the cloud platform can ensure that the Redis service provides normal read-write service and also can ensure the data persistence function of the Redis service.

Description

Method for persistence of Redis data on cloud platform

Technical Field

The invention belongs to the technical field of cloud platform resource management, and particularly relates to a method for persistence of Redis data on a cloud platform.

Background

Redis is a memory type database, user data is stored in a memory of a computer, and data in the memory can be durably stored on a hard disk at regular time by a Redis service. To ensure that data is not lost. Redis will become read-only when persisting data, and stop accepting data write operations. And after the persistence is finished, the normal state is recovered.

The existing solutions are the following:

first, the drop function of the redis service is turned off.

Second, the tolerant redis service interrupts the write operation service for a certain time.

With respect to the first scheme, there is no problem in a scenario where data persistence is not required, but it is obviously not acceptable in a scenario where data persistence is required.

For the second scheme, service reliability cannot be guaranteed, and a system with high requirements for service reliability or a system with more writing operations is displayed to be unacceptable.

Disclosure of Invention

In view of the above, in order to overcome the above drawbacks, the present invention is directed to a method for persisting Redis data on a cloud platform.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

a method for persistence of Redis data on a cloud platform comprises the following steps:

s1, creating two redis instances;

s2, setting the two redis as a high-availability cluster with a master-slave structure; one redis is a master node and the other is a slave node;

s3, closing the data persistence function of the redis on the main node;

and S4, opening the data persistence function of the redis from the node.

Further, in step S2, the master node provides a read-write function, and the slave node provides a read-only function.

Compared with the prior art, the method for persisting Redis data on the cloud platform has the following advantages:

the method for persisting Redis data on the cloud platform can ensure that the Redis service provides normal read-write service and also can ensure the data persistence function of the Redis service.
