刚刚在修改mysql默认配置的时候,发现找不到my.ini文件。按照其他搬运工的说法，打开隐藏的文件也是不行。自己摸索了半天终于找到解决方案。
1、打开“隐藏文件”显示：
2、在url哪里输入： %ProgramData%
2.1、回车以后会得到如下结果，打开mysql文件夹
2.2、然后会得到如下
打开MySQLServer那个文件夹里面就会有my.ini文件了。
一直用的免安装版本，突然有一天开发时控制台一直报错
Data source rejected establishment of connection, message from server: “Too many connections”
上网搜
说是要我修改最大连接，然后我左找右找没找到my.ini/my-default.ini。
不管是c:\下的programData还是安装目录，所以直接新建一个使用。
直接新建文本文件就行,改后缀。
my.ini里面的内容

需要注意的一点是
这里填自己安装目录。
不知道的话查询一下：show variables like ‘datadir’;
指定一下
mysqld --defaults-file="D:\Software\MySql\mysql-8.0.26-winx64\my.ini"
测试一下；修改最大连接

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。
