Mysql自己创建的my.ini不起作用是怎么回事啊

安装的zip版本的mysql5.7.27，根目录下没有my.ini配置文件，按照教程在根目录下创建了my.ini配置文件，如果将my.ini配置文件和mysql绑定的到一起，会无法启动：

而不把my.ini配置文件和mysql绑在一起就没问题，可以正常启动，然而my.ini配置文件将失效：

my.ini配置文件内容如下：

[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://Mysql//mysql-5.7.27-winx64
datadir = D://Mysql//mysql-5.7.27-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

请问有大佬知道这是怎么回事吗？如何才能使用my.ini配置文件？

检查下是否配置了环境变量

看看你修改的my.ini文件是不是正确的路径下的那一个
修改了之后重新启动下看看。

我以前也遇到过这个问题，怎么都无法启动，后来直接搞的安装版，一步到位。
