mysql找不到my.ini文件

问题描述

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。

解决办法

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。

mysql免安装版找不到my.ini配置文件

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

# For advice on how to change settings please see

default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_bin
init_connect='SET NAMES utf8mb4'

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

basedir = D:\Software\MySql\mysql-8.0.26-winx64
datadir = D:\Software\MySql\mysql-8.0.26-winx64\data
port = 3306
# server_id = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
join_buffer_size = 128M
sort_buffer_size = 16M
read_rnd_buffer_size = 16M 
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

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
