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

####################配置文件结束###################
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。
