方法三：
使用pymysql，安装命令：python -m pip install pymysql
MySQL配置
- 解压mysql-8.0.12-winx64.zip到安装目录，比如：D:\mysql
- 添加配置文件my.ini
注意：basedir和datadir根据实际情况填写
[mysqld]
# 设置3306端口
port=3306
# 设置mysql的安装目录
basedir=D:\mysql
# 设置mysql数据库的数据的存放目录
datadir=D:\mysql\data
# 允许最大连接数
max_connections=200
# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统
max_connect_errors=10
# 服务端使用的字符集默认为UTF8
character-set-server=utf8
# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB
# 默认使用“mysql_native_password”插件认证
default_authentication_plugin=mysql_native_password
[mysql]
# 设置mysql客户端默认字符集
default-character-set=utf8
[client]
# 设置mysql客户端连接服务端时默认使用的端口
port=3306
default-character-set=utf8
初始化数据库
cd /d D:\mysql\bin
mysqld --initialize --console
结果如下：（注意记下root用户的初始密码）
C:\WINDOWS\system32>cd /d d:\mysql\bin
d:\mysql\bin>mysqld.exe --initialize --console

安装并开启MySQL服务
mysqld.exe --install mysql
net start mysql
结果如下:
d:\mysql\bin>mysqld.exe --install mysql
The service already exists!
The current server installed: D:\mysql\bin\mysqld.exe MySQL
d:\mysql\bin>net start mysql
MySQL 服务正在启动 ..
MySQL 服务已经启动成功。
修改初始密码为新密码：‘password’
mysql -u root -p
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
结果如下：
d:\mysql\bin>mysql -u root -p
Enter password: ************
