docker mysql authentication_string client does not support authentication 连接问题

docker安装mysql后，本地navicat连接报错client does not support authentication

解决办法：

1. docker ps -a 查找到容器id

2. docker exec -it id /bin/bash 进入mysql容器

3.mysql -u root -proot登陆mysql

此处比较奇怪，我在docker中启动mysql容器指定密码是123456但是123456登陆不了，使用密码root可以登陆

4.use mysql; 进入mysql

5.查询用户表信息：

select host,user,authentication_string from user ;

6.更改host为% user为root的用户的authentication_string

host为%大家可以百度一下，说是方便远程连接

update user set authentication_string = 'root' where user = 'root' and host = '%';

update user set authentication_string = 'root' where user = 'root' and host = 'localhost';

7.如果还不行使用下面语句：

alter user 'root'@'localhost' identified with mysql_native_password by '123456';

alter user 'root'@'%' identified with mysql_native_password by '123456';

然后navicat登陆就成功啦
