mysql 5.7.11 winx64初始密码修改

从官网下载mysql/' target='_blank'>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

net start mysql 

启动成功后，登录mysql

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

use mysql

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

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。
