mysql 8.0找不到my.ini配置文件
“mysql 8.0 来了，该更新版本了”
为了方便日后的工作，在这里整理了一下mysql的基本配置
新建my.ini配置文件
有些时候需要设置mysql的属性，一般的可以通过以下方式找到my.ini文件的路径
mysql> show variables like 'datadir'; +---------------+--------------------------------------------+ | Variable_name | Value | +---------------+--------------------------------------------+ | datadir | C:\ProgramData\MySQL\MySQL Server 8.0\ | +---------------+--------------------------------------------+ 1 row in set (0.03 sec)
执行结果就是配置文件的路径
注：可以通过select @@basedir; 获取到mysql的安装路径
但是笔者的mysql有点傲娇，不太一样：
mysql> show variables like 'datadir'; +---------------+--------------------------------------------+ | Variable_name | Value | +---------------+--------------------------------------------+ | datadir | C:\install\mysql\mysql-8.0.16-winx64\data\ | +---------------+--------------------------------------------+ 1 row in set (0.03 sec)
并且该目录下根本就没有my.ini配置文件。。。。。
嘿嘿~~ 那就新建一个！
比如在这里新建一个空的my.ini：
C:\install\mysql\mysql-8.0.16-winx64\my.ini
内容可以copy一份这里的
# 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 # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL. [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.

或者只加入自己想要的配置，例如：
[mysqld] ft_min_word_len=1
然后打开cmd，进入命令行，输入：
mysqld --defaults-file="C:\install\mysql\mysql-8.0.16-winx64\my.ini"
即修改mysql的配置文件路径
嘿嘿 _
重启mysql服务即可，查看是否生效，可以执行类似的命令：
mysql> show variables like '%ft%'; +---------------------------------+----------------+ | Variable_name | Value | +---------------------------------+----------------+ | ft_boolean_syntax | + -><()~*:""&| | | ft_min_word_len | 1 | +---------------------------------+----------------+ 17 rows in set (0.03 sec)
如果还没有安装mysql服务，那更加好，只需要在安装的时候输入即可：
mysqld --install "MySql80" --defaults-file="C:\install\mysql\mysql-8.0.16-winx64\my.ini"
总结
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脚本之家。
