为什么mysql服务器字符不能设置为默认.ini（windows）中的设置（utf8）？ 这是my-default.ini 但是在命令行中

正如您所看到的，我在my defualt.ini中确实做了很多设置，但是每次MYSQL服务器启动时，字符集服务器总是1

我希望它是utf8，我怎样才能做到

我想知道为什么

谢谢

您可能需要将my-default.ini复制到my.ini，因为后者是mysqld默认查找的对象

否则，我不能重复你的问题

我在Windows8.1上运行5.6.12。以下是测试用例，从my.ini中没有提到字符集服务器开始：

此时，我将character\u set\u server=utf8添加到相应my.ini的[mysqld]部分；然后重新启动mysqld。现在

mysql> show variables like 'char%';

这和你做的相比如何？

p.S.谢谢你逼我弄明白服务器到底是什么角色。它似乎只为createdatabase提供了一个默认值。几乎不值得担心。
