4.使用命令
1 mysqld --initialize --console

5.安装并启动MySQL服务：
C:\Windows\System32>mysqld install Service successfully installed.C:\Windows\System32>net start mysql MySQL 服务正在启动 . MySQL 服务已经启动成功。
6.使用先前生成的密码登录root用户并使用命令

修改其密码：
C:\Windows\System32>mysql -u root -p Enter password: ************ Welcome to the MySQL monitor. Commands end with ; or \g.
