Docker启动mysql连接报错了

问题：

连接Docker启动的mysql出现：ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded

mysql -h 127.0.0.1 -u root -p
Enter password: ****
ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded

解决方案：

1.进入mysql容器

docker exec -it mysql2 /bin/bash

2.本地连接mysql

mysql -u root -p xxx

3.修改密码
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'root';
