Inside君整理了一份最新基于MySQL 5.6和5.7的配置文件模板，基本上可以说覆盖90%的调优选项，用户只需根据自己的服务器配置稍作修改即可，如InnoDB缓冲池的大小、IO能力（innodb_buffer_pool_size，innodb_io_capacity)。特别注意，这份配置文件不用修改，可以直接运行在MySQL 5.6和5.7的版本下，这里使用了小小的技巧，具体可看配置文件。如果配置参数存在问题，也可以及时反馈Inside君，我们一起成长。
触发Inside君做这件事情的原因是大部分网络上的MySQL配置文件都非常非常古老，大多都是基于MySQL 5.1的版本，这导致了绝大部分MySQL并没有运行在最优的环境，从而导致一些错误的使用，亦或是灾难性事故的发生，比如数据丢失，主从数据不一致等。而这些问题早在5.6版本及以后的版本中得到了解决。
最后，抛弃你那所谓的、陈旧的、错误的MySQL配置文件，面向一个崭新的高性能、高可靠、高可扩展MySQL时代，你要做的就是下载这份配置文件并用于你的生产环境。配置如下：
