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
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

[client]
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 # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
basedir = D:SoftwareMySqlmysql-8.0.26-winx64
datadir = D:SoftwareMySqlmysql-8.0.26-winx64data
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:SoftwareMySqlmysql-8.0.26-winx64my.ini"

测试一下；修改最大连接
