Question: Navicat to seek death inside connection is removed, and then re-establish the connection, resulting in this:

Online check the information, found the back of their own forgotten passwords, so follow the tutorial to go again

1. Sql service first stopped, so that subsequent operations

另外解决办法：
参考：https://www.cnblogs.com/zhiliang9408/p/9851939.html
主要的问题是找到这里面说的my.ini文件，开始怎么都没找到，后面用Evernote找到了，在C:\ProgramData\MySQL\MySQL Server 5.7
在文档内搜索mysqld定位到[mysqld]文本段，在[mysqld]后面任意一行添加“skip-grant-tables”用来跳过密码验证的过程

• 重启mysql：net start MySQL57

• 输入：mysql -u root -p
  注意，这里的提示输入密码，直接回车即可
  输入：show databases;
  看下是否的确进入了mysql

• 输入update user set password=password("jiayou7311") where user='root';修改密码，结果：
  ERROR 1054 (42S22): Unknown column 'password' in 'field list
  

原因：原因是 5.7版本下的mysql数据库下已经没有password这个字段了，password字段改成了authentication_string
输入：
update mysql.user set authentication_string=password('jiayou7311');
修改成功

• 刷新：flush privileges;
  

• Exit: quit
  

• Delete my.ini in the field to add swap

3. Log back
   mysql -u root -p
   success:
