[mysqld]# mysql安装目录
# set basedir to your installation path
basedir=E:/mysql
# mysql数组目录
# set datadir to the location of your data directory

mysql8.0 账户验证方式变更:mysql_native_password -> caching_sha2_password
数据初始化方式:
- 安全,root账户密码随机生成,标识过期,控制台打印:mysqld --initialize --console
- 不安全,root账户不指定密码:mysqld --initialize-insecure --console
