MySQL问题记录--Can't connect to MySQL server on localhost (10061)解决方法

本文mysql的安装环境为win10 64位，mysql版本为MySQL5.7

问题描述：在命令行输入 mysql -u root -p 登录mysql，返回”Can't connect to MySQL server on localhost (10061)”错误

问题原因：在一番谷歌后，查到问题原因是mysql没有启动。

解决方法：1、将mysql加入到Windows的服务中。切换到mysql安装目录下的bin文件夹，命令行运行"mysqld --install"

1 C:\Program Files\MySQL\MySQL Server 5.7\bin> mysqld --install
2 Service successfully installed.

　　此时若使用“net start mysql”成功启动msyql，则无须执行下面步骤

　　　　　2、初始化mysql数据库，输入“mysqld --initialize --user=root --console”。下面红色文字为初始化后的root 密码

C:\Program Files\MySQL\MySQL Server 5.7\bin>mysqld --initialize --user=root --console

　　　　  3、此时使用“net start mysql”成功启动msyql

　　　　4、使用生成的密码登录mysql，执行select * from mysql.user

针对这个错误You must reset your password using ALTER USER statement before executing this statement.

然后执行alter user user() identified by 'XXXX';  XXXX代表密码

出现  

mysql> alter user user() identified by '2021';
Query OK, 0 rows affected (0.09 sec)

成功
