Editor to share with you how to configure auto_increment_offset and auto_increment_increment in mysql, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

There are self-growing fields in mysql, and two self-growing related configurations need to be set when doing primary primary synchronization of the database: auto_increment_offset and auto_increment_increment.

Auto_increment_offset means that since the growth field starts from that number, his value range is 1.. 65535

Auto_increment_increment represents the amount of each increment in the self-growing field. The default value is 1, and the range of values is 1. 65535

In the master master synchronization configuration, the auto_increment_increment growth of both servers needs to be configured to 2, while the auto_increment_offset should be configured to 1 and 2. 0 respectively.

This avoids conflicts between the values of the self-growing fields when two servers update at the same time.
