1. 解压压缩包,放置到任意目录
这是我的目录:D:\Python\mysql-8.0.12-winx64\
2. 初始化
使用命令: --initialize --console
使用CMD命令操作如下:
C:\Windows\system32>D:\Python\mysql-8.0.12-winx64\bin\mysqld --initialize --console
2018-09-13T14:36:55.758742Z 0 [System] [MY-013169] [Server] D:\Python\mysql-8.0.12-winx64\bin\mysqld (mysqld 8.0.12) initializing of server in progress as process 3104
2018-09-13T14:37:12.072904Z 5 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: 4P!w2fqBruGi
2018-09-13T14:37:23.274980Z 0 [System] [MY-013170] [Server] D:\Python\mysql-8.0.12-winx64\bin\mysqld (mysqld 8.0.12) initializing of server has completed
记录下密码,后面修改密码还要用</br>
在这里:
[Server] A temporary password is generated for root@localhost: 4P!w2fqBruGi
最后面的 ==4P!w2fqBruGi== 就是密码,密码是随机生成的每个人都不一样
3. 安装
使用命令: mysqld --install
C:\Windows\system32>D:\Python\mysql-8.0.12-winx64\bin\mysqld --install
Service successfully installed.
4. 启用服务
使用命令: net start mysql
C:\Windows\system32>net start mysql
MySQL 服务正在启动 ..
MySQL 服务已经启动成功。
5. 修改密码
使用命令: ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码';
我设置的密码是111111 ,告诉你们没关系
D:\Python\mysql-8.0.12-winx64\bin>mysql -u root -p
Enter password: ************
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.0.12
mysql> ALTER user 'root'@'localhost' IDENTIFIED BY '111111'
-> ;
Query OK, 0 rows affected (1.98 sec)
6. 使用新密码登陆
使用命令:mysql -u root -p
D:\Python\mysql-8.0.12-winx64\bin>mysql -u root -p
Enter password: ******
Welcome to the MySQL monitor. Commands end with ; or \g.

7.配置环境变量:
- 进入 计算机--高级系统设置--高级--环境变量
- 然后新建系统变量
- 变量值改为自己mysql解压的路径
- 变量名:MYSQL_HOME
- 变量值:D:\Python\mysql-8.0.12-winx64\
- path里添加:%MYSQL_HOME%\bin;(分号不要忘记)
