Navicat连接docker容器中的mysql报错2003解决办法

使用Navicat远程连接docker容器中的mysql 报2003错误

解决办法：

一、在docker中启动mysql,定义端口号3306

[root@localhost ~]# docker run -p 3306:3306 --name mysql01 -e MYSQL_ROOT_PASSWORD=123456 -d mysql

二、执行命令，输入密码

[root@localhost ~]# docker exec -it mysql01 bash

root@863b69d78d4f:/# mysql -uroot -p

Enter password:

mysql> 

三、授权

mysql> GRANT ALL ON *.* TO 'root'@'%';

四、刷新权限

mysql> flush privileges;

五、更改加密规则

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;

六、更新root用户密码（123456是我的密码，要替换成自己的）

mysql> ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

七、刷新权限

mysql> flush privileges;
