安装和初始化

进入 mysql 的 bin 文件夹以管理员身份运行 cmd

执行 mysqld install，在服务中会出现 MySQL 服务（如果不用管理员身份运行，将会因为权限不够而出现错误：Install/Remove of the Service Denied!）
（Windows 移除服务命令：sc delete mysql）

执行 mysqld --initialize --console （此时会在 mysql 根目录下生成 data 文件夹）

“qZ*Hyh=-u59=” 为 root 账号初始密码，记住这个密码。
如果忘记或者没记住，删掉初始化的 data 目录，再执行一遍初始化命令（mysqld --initialize --console），又会重新生成。当然也可以使用安全工具强制改密码，用什么方法，自己随意。

启动 MySQL

cmd 中继续输入 net start mysql 启动 mysql

停止 MySQL：net stop mysql

修改 MySQL 账号密码

登录（密码是生成的 “qZ*Hyh=-u59=”）：
mysql -uroot -p

修改密码执行以下命令：
ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
flush privileges;
