s generated for root@localhost: *kEkIrsF3Av& ，初始密码就是：*kEkIrsF3Av&,记住它，别关闭了，后面登录会用到
要是你手贱，关快了，或者没记住，删掉初始化的 datadir 目录，再执行一遍初始化命令，又会重新生成的
启动服务
接着上面步骤在bin目录下执行命令:mysqld --install [服务名]
mysqld --install mysql
D:\soft\mysql8011\mysql-8.0.11-winx64\bin>mysqld --install mysql Service successfully installed.安装完成之后，就可以通过命令net start mysql启动MySQL的服务了。通过命令net stop mysql停止服务
D:\soft\mysql8011\mysql-8.0.11-winx64\bin>net start mysql mysql 服务正在启动 ... mysql 服务已经启动成功。修改密码
在MySQL安装目录的 bin 目录下执行命令
mysql -u root -p
会提示输入密码，记住了上面第步安装时的密码 *kEkIrsF3Av&：，填入即可登录成功,进入MySQL交互模式
D:\soft\mysql8011\mysql-8.0.11-winx64\bin>mysql -u root -p
Enter password: ************
