1、下载最新版本的MYSQL数据库，本版8.0.16

2、我安装在G:

3、将mysql下bin的文件路径保存到环境变量path

4、创建my.cnf文件

5、输入：

[mysqld]
basedir=c:/mysql-5.7.23-winx64
datadir=c:/mysql-5.7.23-winx64/data
character-set-server=utf8
explicit_defaults_for_timestamp
[mysql]
#default-character-set=gbk

6、启动数据库
net start mysql

7、初始化数据库

mysqld --initizlize --console

8、若失败，创建在Mysql文件夹下创建data文件夹

2019-07-15T03:33:29.829688Z 0 [System] [MY-010116] [Server] G:\mysql-8.0.16-winx64\bin\mysqld.exe (mysqld 8.0.16) starting as process 9380

9、如初始化失败，则删除data，重新创建data文件

10、再次执行，会生成一个临时登录密码

11、登录数据库 musql -uroot -p

12、输入临时密码

13、再修改密码
alter user ‘root’@‘localhost’ identified by ‘123456’；

以上，加油吧
