从官网下载MySQL-5.7.11-winx64压缩版，安装后发现竟然有密码，尝试无果，通过修改密码搞定
安装成功后：
关闭mysql服务在跟目录下修改文件my.ini，内容如下：注意两点 1：内容中myql的安装目录换成读者的安装目录；2最后一行代表登录是否需要密码，这里我们绕过密码登录进入mysql修改密码，所以不注释skip-grant-tables

修改保存后，在cmd中，由于我们已经在path配置了环境变量，所以我们可以直接启动mysql
|
1
|
net start mysql |
启动成功后，登录mysql
|
1
|
mysql -u root -p |
密码为空 这里我们直接回车登录成功
登录成功后，我们修改数据库执行如下
|
1
|
use mysql |
|
1
|
update user set authentication_string=password("123456") where user="root"; |
这里注意最后必需加上分号
成功后刷新
|
1
|
flush privileges; |
致此我们密码就修改成功了，退出关闭mysql服务，然后把my.ini中最后一行注释掉，从新启动mysql服务，发现新密码生效。
