移除docker：docker rm mysql

停止容器：docker stop mysql

docker exec -it mysql /bin/bash

cd /etc/mysql/mysql.conf.d/

echo 'max_allowed_packet=32M' >> mysqld.cnf

show VARIABLES like '%max_allowed_packet%'; 

查看日志：

docker logs -f -t --tail 10 容器ID

错误处理：

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

解决方案（在linux环境下）：

1.进入mysql容器

docker exec -it mysql /bin/bash

2.进入mysql

mysql -uroot -p123456

3.修改密码

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