mysql5.6的配置⽂件_MySQL5.65.7最优配置⽂件模板
（my.ini）
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：
