首先，是安装成功的

RT，在安装成功的前提下：

root@ubuntu:/home/ubuntu/Hydro/install/docker# docker-compose up -d
oj-mongo is up-to-date
oj-minio is up-to-date
oj-backend is up-to-date
oj-judge is up-to-date

然后oj-mongo一直restarting

利用docker ps -a命令：

root@ubuntu:/home/ubuntu/Hydro/install/docker# docker ps -a

该oj-mongo没有输出日志。

oj-judge输出日志：

貌似是因为mongo无法正常启动导致其他容器也无法启动了。

bdfswg。加载页面时会拒绝连接。求解决方案。
