Inside a copy of the latest MySQL 5.6 and 5.7-based profile templates, basically covering 90% of tuning options, users only need to modify their server configuration slightly, such as the size of the InnoDB buffer pool, IO capability (innodb_buffer_ pool_size,innodb_io_capacity). It is important to note that this configuration file is not modified and can be run directly in MySQL version 5.6 and 5.7, where a small trick is used to see the configuration file. If there is a problem with configuration parameters, can also be timely feedback inside, we grow together.
Trigger inside do this because most of the network MySQL configuration files are very very old, mostly based on the MySQL 5.1 version, which led to the vast majority of MySQL is not running in the optimal environment, resulting in a number of wrong use, or catastrophic accident occurred, such as data loss, master-slave data inconsistency and so on. These issues were resolved as early as the 5.6 and later versions.
Finally, discard your so-called, stale, and wrong MySQL profile for a new high-performance, high-reliability, high-scalability MySQL era, all you have to do is download the configuration file and use it for your production environment. The configuration is as follows:
