一般对于刚刚安装好的mysql，如果勾选启用mysql lineclient的话。可以直接通过找到开始---程序--- mysql command line client如下图

点击mysql命令行之后，会提示你输入root密码。输入正确的root密码之后即可连接到msyql数据库里啦

二 Cmd命令行怎么连接数据库

如果没有安装mysql命令行的话，我们可以通过找到 mysqld所在的路径（复制mysqld.exe所在路径）

使用cd切换到msyqld.exe路径下，然后输入mysql连接命令如下图

格式是：

Mysql -P 端口号 -h mysql主机名\ip -u root （用户） -p

如果是命令行是mysql所在的本机

而且用默认的端口 3306 直接输入 mysql -u root -p 即可

第三方mysql数据库连接工具

通过第三方数据库连接工具这些就很多啦，如下图设置好相关参数即可

连接进去之后，也就是比较人性化的图形界面了。

其他远程连接工具

Phpmyadmin 无疑是使用最广泛的php管理数据库的图形化工具了，由于涉及到不同的环境和路径。本例咗嚛不做详细 *** 作
