Inside has compiled a latest configuration file template based on MySQL 5.6 and 5.7, which basically covers 90% of the tuning options. Users only need to make slight modifications according to their own server configuration, such as the size of the InnoDB buffer pool. , IO capability (innodb_buffer_pool_size, innodb_io_capacity). Special note that this configuration file does not need to be modified and can be run directly under MySQL 5.6 and 5.7 versions. A few tricks are used here. Please refer to the configuration file for details. If there is a problem with the configuration parameters, you can also give timely feedback to Insider and we will grow together.

The reason that triggered Inside to do this is that most of the MySQL configuration files on the Internet are very, very old, and most of them are based on the MySQL 5.1 version. This has resulted in most MySQL not running in the optimal environment, thus This may lead to incorrect use or catastrophic accidents, such as data loss, master-slave data inconsistency, etc. These problems have been solved as early as version 5.6 and later versions.

Finally, abandon your so-called, old, wrong MySQL configuration file, and face a new era of high performance, high reliability, and high scalability MySQL. All you have to do is download this configuration file and use it in your production environment . The configuration is as follows:
