問題：
連接Docker啟動(dòng)的mysql出現(xiàn)：ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded
C:\mysqldata>mysql -h 127.0.0.1 -P 13306 -uroot -p
Enter password: ****
ERROR 2059 (HY000): Authentication plugin 'caching_sha2_password' cannot be loaded: ?ò2?μ????¨μ??￡?é?￡
解決方案（在linux環(huán)境下）：
1.進(jìn)入mysql容器
docker exec -it mysql2 /bin/bash
2.進(jìn)入mysql
mysql -uroot -pmima
3.修改密碼
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'root';
