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';
