使用docker搭建doris集群，使用docker-compose官方例子搭建：
，搭建完成后，重启docker 发现be就无法注册到fe中了。
搭建例子：https://doris.apache.org/zh-CN/docs/dev/install/construct-docker/run-docker-cluster

发现是官方的一个bug，有位大神回答：
You can’t change password in this Docker IMAGE. Because in BE initiation process, its will execute show frontends using mysql-client. Therefore, if you change the password, the initiation bash script couldn’t execute sql. So an error occurred and BE couldn’t startup normally.
可以试着给be启动的mysql命令里面加上自己新的密码, 在be容器里面, /usr/local/bin/中的entry_point.sh和init_be.sh脚本中, 使用mysql命令的部分, 加上-p[新密码]
