windows怎样命令行安装mysql数据库

使用命令行创建MySql数据库，首先要登录MySql数据库系统

创建步骤如下：

Windows操作系统下，开始——运行，打开"运行"对话框,输入cmd，点击“确定”即可进入DOS窗口，输入登录MySQL数据库命令

mysql

-h

127.0.0.1

-u

root

-p

参数含义：

mysql是登录数据库的命令，-h

后面跟服务器的IP，由于本示例MySql服务器安装在本地，因此IP地址为127.0.0.1；-u

后面跟用户名，本示例采用

root用户登录；-p

后面跟登录密码。

输入上述命令后回车，再输入登录密码，一般默认密码是root

回车

成功登录MySQL数据库后就可以在DOS下使用SQL语句"create

database"创建数据库了

mysqlcreate

database

要创建的新数据库名;
