+# 使用 Docker 部署 `scnuoj`
+
+众所周知，`scnuoj` 性能垃圾，支持的功能少还难以配置。但是没办法，生活还是要继续，性能和功能想解决还得费点时间。那就先解决难以配置的问题吧。
+
+## 1. 环境配置
+
+### 1.1 安装 Git
+
+```shell
+#debian/ubuntu
+sudo apt install git -y
+#centos/rehl
+sudo yum install git -y
+```
+
+### 1.2 安装 Docker
+
+请参考[这篇教程](https://mirrors.tuna.tsinghua.edu.cn/help/docker-ce/)。
+
+### 1.3 安装 docker-compose
+
+```shell
+#debian/ubuntu
+sudo apt install docker-compose -y
+#centos/rehl
+sudo yum install docker-compose -y
+```
+
+至此，环境配置已经完成
+
+## 2. 获取并修改源码
+
+### 2.1 获取源码
+
+```shell
+git clone https://github.com/scnu-socoding/scnuoj.git
+```
+
+### 2.2 修改数据库信息
+
+#### 2.2.1 修改 `/docker-compose.yaml`
+
+将 `MYSQL_ROOT_PASSWORD` 的值更改为你想要的密码
+
+#### 2.2.2 修改 `/config/db.php`
+
+将 `dsn` 修改为 `mysql:host=mysql;dbname=scnuoj`
+
+将 `username` 修改为 `root`
+
+`password` 修改为 你刚才设置的密码
+
+#### 2.2.3 修改 `/judge/src/judge.c`
+
+将 `use_ptrace` 的值修改为 `0`
+
+> Tips: 这里修改的原因是 P trace 机制和 Docker 存在兼容性问题导致。Docker 里的 system call 的值貌似不固定（?）
+
+#### 2.2.4 修改 `/polygon/src/judge.c`
+
+同上
+
+#### 2.2.5 修改 `/conf.d/Caddyfile`
+
+详情请根据 Caddy 官方文档。
+
+## 3. 安装
+
+首次运行需要安装 `scnuoj` 。
+
+先在 `/scnuoj` 目录下运行：
+
+```shell
+docker-compose up -d --build
+```
+
+生成镜像需要时间，请耐心等待打包完成。
+
+运行成功后，进入 `php` 容器。
+
+首先，先使用 `docker container ls` 命令获取 `php` 容器的 `CONTAINER ID`。
+
+然后，输入 `docker exec -it 刚才获取的ID sh` 进入容器。
+
+运行 `./yii install` 进行安装。根据提示输入管理员账号、密码和邮箱即可。
+
+> 如果提示权限不足则先执行 `chmod +x yii` 。
+
+输入 `exit` 退出容器。此时 `scnuoj` 已经搭建完成。
+
+输入:
+
+```shell
+docker-compose down; docker-compose up -d
+```
+
+重启容器，即可提供服务。
+
+## 迁移
+
+容器化最大的好处就是迁移的时候十分方便。迁移时只需要输入 `docker-compose down` 在源服务器上停止服务。将整个文件夹打包迁移到新服务器上，重复第一步的环境配置，即可通过 `docker-compose up -d` 一键开启服务。
+
+## 判题机开启 oi 模式
+
+进入判题机容器，kill 掉原有的判题机进程，然后输入
+
+```shell
+./judge/dispatcher -o
+./polygon/polygon -o
+
+```
+
+即可开启 oi 模式。如需关闭，重启容器即可。
