Abstract

The invention provides a high available ID generator and an ID generation method and an ID generation device thereof. The high available ID generator comprises a master database deployed in a distributed manner, at least one slave database and at least two guard processes, wherein the master database and the slave database provide a unique ID and a port outwards for service via a load balancing service; when running normally, the master database is used for receiving an ID generation request, and generating the unique ID according to the request, wherein the ID is an auto-incremented ID; whenthe guard process detects that the master database goes down, master and backup switching is performed on the master database and the next slave database that runs normally; and a load balancing interface is called back, and an access weight of each database is modified. The slave database is used for receiving the ID generation request after being switched to the master database, and generating the unique ID according to the request; according to the high available ID generator and the ID generation method and device provided by the invention, the master and standby switching can be performedon the master database and the slave database to generate the ID, so that the high availability is ensured, and the occurrence of a single point failure is avoided.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a highly available ID generator and its ID generating method and device. Background technique [0002] As a kind of identification, ID plays a very important role in identification on the Internet. Currently, ID generation has multiple implementations: [0003] 1. Use mysql (a relational database management system) to generate a unique ID by auto-incrementing ID [0004] The disadvantage is: in the case of a single database or read-write separation such as one master and multiple slave databases, only one master database can generate IDs, and there is a risk of single point of failure. The optimized version based on this is to set up multiple Master databases, and the starting value and step size of each database are different, such as Master1 generates 1, 3, 5; Master2 generates 2, 4, 6, etc.; this avoids single point There is a risk of failure, but there is a problem of...
