本文参考前文 win10安装mysql5.7
MySQL 5.7.36 国内 阿里云 下载地址
https://mirrors.aliyun.com/mysql/MySQL-5.7/mysql-5.7.36-winx64.msi
安装 mysql-5.7.36-winx64.msi 时,我选择的 custom 自定义安装
安装目录 D:\software\MySQL\MySQL-Server-5.7
安装完成后
在 D:\software\MySQL\MySQL-Server-5.7 这个目录下 创建 data 目录、新建 my.ini 文件
my.ini 文件就是 MySQL 数据库的具体配置
[mysql]
# 设置mysql客户端默认字符集
default_character_set=utf8mb4
[mysqld]
#设置3306端口
port = 3306
# 设置mysql的安装目录
basedir=D:\\software\\MySQL\\MySQL-Server-5.7
# 设置mysql数据库的数据的存放目录
datadir=D:\\software\\MySQL\\MySQL-Server-5.7\\data
# 允许最大连接数
max_connections=200
# 服务端使用的字符集默认为8比特编码的latin1字符集
character_set_server=utf8mb4
# 创建新表时将使用的默认存储引擎
default_storage_engine=INNODB
# 设置日志时间为系统时间
log_timestamps=SYSTEM
然后去配置 环境变量
然后去配置环境变量


系统变量
MYSQL_HOME
把解压目录配置进去
D:\software\MySQL\MySQL-Server-5.7

然后
Path
%MYSQL_HOME%\bin

然后 win + r --> cmd --> ctrl+shift+enter--> 进入控制台管理员模式
C:\Users\Administrator>cd /d %MYSQL_HOME%\bin
D:\software\MySQL\MySQL-Server-5.7\bin>
D:\software\MySQL\MySQL-Server-5.7\bin>mysqld -install
Service successfully installed.
D:\software\MySQL\MySQL-Server-5.7\bin>mysqld --initialize-insecure --user=mysql
D:\software\MySQL\MySQL-Server-5.7\bin>net start mysql

去看 data 目录下 err 日志

默认初始化是没设置密码,密码为空,所以首次登录直接回车,然后重新设置密码即可
数据库连接信息:
主机:localhost
