mysql5.6 ERROR 1049 (42000): Unknown database ‘ *** ‘_error 1049 (42000): unknown database 'root

mysql5.6登陆时报 ERROR 1049 (42000): Unknown database ’ *** ’

mysql -u root -p root

D:\MySQL\bin>mysql -u root -p root

排查问题：

一：首先我的本地myslq服务是开启的

二：环境变量配置了（如果没配 不会报这个错 是无法识别指令）
三：看报错 未知的数据库 root -p 密码 这是我登陆的密码
是不是我输入方式不对 -u 后面不加空格

D:\MySQL\bin>mysql -uroot -p root
Enter password: ****
ERROR 1049 (42000): Unknown database 'root'

-p 后面不加空格

D:\MySQL\bin>mysql -uroot -proot

进来了 说明-u后面加不加空格没有关系 -p后面不加空格 直接跟密码即可！
