青岛大学OnlineJudge搭建
宗政博文
OnlineJudge
环境准备
- ubuntu 18.04
- docker
- docker-composer
换源
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
sudo vim /etc/apt/sources.list
替换内容为
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
安装docker
apt install docker.io
apt install docker-composer
换docker源
sudo vim /etc/docker/daemon.json
#替换为
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn","https://mirror.ccs.tencentyun.com"]
}
安装程序
#下载
git clone -b 2.0 https://github.com/QingdaoU/OnlineJudgeDeploy.git && cd OnlineJudgeDeploy
#启动
sudo docker-compose up -d
数据备份
- 备份
在backup文件夹下有个数据备份脚本 直接运行即可
- 迁移
docker cp db_backup_xxxxxxx.sql oj-postgres:/root
docker exec -it oj-postgres bash
psql -U onlinejudge postgres
drop database onlinejudge;
\q
psql -f /root/db_backup_xxxxxxx.sql -U onlinejudge postgres
然后备份 /OnlineJudgeDeploy/data/backend public test_case 文件夹
请先恢复数据库再拷贝备份的public和test_case文件夹，否则在判题时会显示编译错误，点击会显示测试用例不存在。
添加判题服务器
满足以下条件
- Token一致
- 进行测试用例的多机同步
主机master配置
在最后添加以下内容
oj-rsync-master:
image: registry.cn-hangzhou.aliyuncs.com/onlinejudge/oj_rsync
container_name: oj-rsync-master
volumes:
- $PWD/data/backend/test_case:/test_case:ro
- $PWD/data/rsync_master:/log
environment:
- RSYNC_MODE=master
- RSYNC_USER=ojrsync
- RSYNC_PASSWORD=CHANGE_THIS_PASSWORD ##这里是同步的密码
ports:
- "0.0.0.0:873:873"
从slave设置
删掉除了judge-server的所有service ,添加以下内容
oj-rsync-slave:
image: registry.cn-hangzhou.aliyuncs.com/onlinejudge/oj_rsync
container_name: oj-rsync-slave
volumes:
- $PWD/data/backend/test_case:/test_case
- $PWD/data/rsync_slave:/log
environment:
- RSYNC_MODE=slave
- RSYNC_USER=ojrsync
- RSYNC_PASSWORD=CHANGE_THIS_PASSWORD ###这里是同步的密码
- RSYNC_MASTER_ADDR=YOUR_BACKEND_ADDR ###主服务器的IP地址
同步修改 RSYNC_PASSWORD，并将 RSYNC_MASTER_ADDR 修改为运行了 oj-rsync-master 服务的地址，不需要端口号，如 example.com 或者 192.168.1.10。
然后给 JudgeServer 添加
ports:
- "0.0.0.0:80:8080"
的端口配置，同时还需要修改
SERVICE_URL为新的机器的地址BACKEND_URL的域名为已部署好的主机的地址 (master地址)TOKEN和已部署好主机TOKEN一致。
运行 docker-compose up -d 即可启动一台新的 JudgeServer,tail -f data/rsync_slave/rsync_slave.log 可以看到测试用例同步进度，在已部署好主机的后台可以看到新的 JudgeServer 的心跳状态。
以下是示例配置
