### 1. 后端部署
**linux下安装下载docker，自行百度**
#### 1.1 安装MySQL
1. 创建自定义网络（用于容器通讯）
```shell
docker network create hoj-network
```
2. 查看网络
```shell
docker network ls
```
3. 创建挂载文件夹
```shell
//mysql配置文件
mkdir -p /data/mysql/conf
//mysql数据文件路径
mkdir –p /data/mysql/data
//日志文件路径
mkdir -p /data/mysql/logs
```
4. 启动mysql
```shell
docker run -p 3306:3306 --name mysql -d \
--restart=always \
--network hoj-network \
-v /data/mysql/conf:/etc/mysql/conf.d \
-v /data/mysql/logs:/logs \
-v /data/mysql/data:/data \
-e MYSQL_ROOT_PASSWORD=admin \
mysql:5.7
```
5. 启动成功后 使用docker ps 可查看 如果正常则进行数据库创建操作
6. 创建名字叫hoj的数据库，执行脚本在sqlAndSetting文件夹里面或者 [hoj.sql](https://gitee.com/himitzh0730/hoj/blob/master/sqlAndsetting/hoj.sql)、[hoj-data.sql](https://gitee.com/himitzh0730/hoj/blob/master/sqlAndsetting/hoj-data.sql)
7. 创建名字叫nacos的数据库，执行脚本在sqlAndSetting文件夹里面或者 [nacos.sql](https://gitee.com/himitzh0730/hoj/blob/master/sqlAndsetting/nacos-mysql.sql)
#### 1.2 注册中心与配置中心naco
1. 执行docker命令，拉取nacos镜像。
```shell
//查询nacos镜像
docker search nacos
//拉取镜像
docker pull nacos/nacos-server
//查看镜像
docker images
```
2. 启动nacos
```shell
docker run --env MODE=standalone --network hoj-network --name nacos -d -p 8848:8848 nacos/nacos-server
```
3. 查看自定义网络中各容器ip，一般该network的ip应该是**172.18.0.2或172.19.0.2**
```shell
//查看网络
docker network ls
//查看网络容器
docker network inspect hoj-network
```
4. 进入nacos容器修改配置
```shell
// 进入容器
docker exec -it nacos bash
// 修改容器配置
cd conf
vi application.properties
```

5. 重启容器
```shell
docker restart nacos
```
6. 连上nacos，将后端服务需要的配置添加进去
```she
http://ip:8848/nacos/index.html
nacos/nacos(用户名和密码)
```
**登陆后，点击添加**
![在这里插入图片描述](https://img-blog.csdnimg.cn/20210416154428657.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzg1MzA5Nw==,size_16,color_FFFFFF,t_70)
**依次添加后台服务的配置文件和判题服务的配置文件**
![在这里插入图片描述](https://img-blog.csdnimg.cn/20210416154647434.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzg1MzA5Nw==,size_16,color_FFFFFF,t_70)
7. hoj-data-backup-prod.yml的配置如下，请自行修改
```yaml
hoj:
jwt:
# 加密秘钥
secret: zsc-acm-hoj
# token有效时长，24小时，单位秒
expire: 86400
# 6小时内还有请求，可进行刷新
checkRefreshExpire: 21600
header: token
judge:
# 调用判题服务器的token
token: zsc-acm-hoj-judge-server
db: # mysql数据库服务配置
host: your_mysql_host
port: your_mysql_port
name: your_mysql_database_name # 默认hoj
username: your_mysql_username
password: your_mysql_password
mail: # 邮箱服务配置
ssl: true
username: your_email_username
password: your_email_password
host: your_email_host
port: your_email_port
background-img: https://cdn.jsdelivr.net/gh/HimitZH/CDN/images/HCODE.png # 邮箱系统发送邮件模板的背景图片地址
redis: # redis服务配置
host: your_redis_host
port: 6371
password: your_redis_password
web-config:
base-url: http://www.hcode.top # 后端服务地址
name: zsc-acm-hoj # 后端服务地址
short-name: hoj # oj简写
register: true
footer: # 网站页面底部footer配置
record:
name: 浙ICP备20009096号-1 # 网站备案
url: http://www.hcode.top # 网站域名
project: # 项目
name: HOJ # 项目名字
url: https://gitee.com/himitzh0730/hoj # 项目地址
hdu:
account:
username: hdu账号1用户名,hdu账号2用户名,...
password: hdu账号1密码,hdu账号2密码,...
cf:
account:
username: cf账号1用户名,cf账号2用户名,...
password: cf账号1密码,cf账号2密码,...
```
8. 添加好后点击发布，再次添加hoj-judge-server-prod.yml，流程一样
```yaml
hoj:
judge:
db:
username: your_mysql_username
password: your_mysql_password
host: your_mysql_host
port: your_mysql_port
name: your_mysql_database_name # 数据库名字默认hoj
# 调用判题服务器的token，与数据服务后台必须一致！
token: zsc-acm-hoj-judge-server
redis:
host: your_redis_host
port: your_redis_port
password: your_redis_password
```
#### 1.3 Redis部署
依旧使用docker部署 ,**mypassword是redis的密码，请使用上面配置文件中redis的password，必须一致！**
```shell
//查询目前可用的reids镜像
docker search redis
//选择拉取官网的镜像
docker pull redis
//查看本地是否有redis镜像
docker images
//运行redis并设置密码
docker run -d --name redis -p 6379:6379 redis --requirepass "mypassword" --restart=always
```
#### 1.4 DataBackup数据后台部署
1. 修改该路径**/hoj-springboot/DataBackup/src/main/resources/bootstrap.yml**的相关配置
```yaml
hoj-backstage:
port: 6688
nacos-url: 172.18.0.2:8848 # nacos地址,如果使用了docker network 可用使用network的ip 否则请使用服务器ip
```
2. 使用cmd打开当前JudgeServer文件夹路径，然后使用mvn命令进行打包成jar包
```powershell
mvn clean package -Dmaven.test.skip=true
```
3. 上传到服务器，**使用apt安装JDK8，请自行百度**，然后在当前文件夹同时创建名叫`Dockerfile`的文件，编写内容如下：
```dockerfile
FROM java:8
COPY *.jar /app.jar
CMD ["--server.port=6688"]
EXPOSE 6688
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
ENTRYPOINT ["java","-Xmx512m","-Xms512m","-Xmn256m","-Djava.security.egd=file:/dev/./urandom","-jar", "/app.jar"]
```
4. 在当前文件夹使用命令打包成docker镜像
```shell
// 使用dockerfile打包成镜像
docker build -t hoj .
// 查看hoj镜像是否存在
docker images
```
5. 启动容器
```shell
docker run -d -p 6688:6688 --name hoj --network hoj-network hoj
```
6. 查看是否成功
```shell
docker ps
```
#### 1.5 JudgeServer判题服务部署
> 注意：判题服务可以部署多台云服务器，步骤一样
1. 下载本项目，git clone或者download zip
2. 修改该路径**/hoj-springboot/JudgeServer/src/main/resources/bootstrap.yml**的相关配置
```yaml
hoj-judge-server:
max-task-num: -1 # -1表示最大并行任务数为cpu核心数*2
ip: 127.0.0.1 # -1表示使用默认本地ipv4，若是部署其它服务器，务必使用公网ip
port: 8088 # 端口号
name: hoj-judger-1 # 判题机名字 唯一不可重复！！！
nacos-url: 127.0.0.1:8848 # nacos地址
remote-judge:
open: true # 当前判题服务器是否开启远程虚拟判题功能
max-task-num: -1 # -1表示最大并行任务数为(cpu核心数*2)*2
```
3. 使用cmd打开当前JudgeServer文件夹路径，然后使用mvn命令进行打包成jar包
```shell
mvn clean package -Dmaven.test.skip=true
```
4. 打包成功后在路径**/hoj-springboot/JudgeServer/target/** 文件夹内找到类似JudgeServer.jar的jar包，然后将该jar包与**/judger**文件夹内的Judger-SandBox文件（go打包的linux系统下可执行文件）一起上传到云服务器的同一个文件夹内，同时在该文件夹内创建一个JudgeServer.json的文件，JVM的配置可以直接配置，内容如下：
```json
{
"apps" : {
"name":"hoj-judgeServer",
"script":"java",
"args":[
"-XX:+UseG1GC",
"-jar",
"JudgeServer.jar", // 注意为jar包名字
],
"error_file":"./log/err.log",
"out_file":"./log/out.log",
"merge_logs":true,
"log_date_format":"YYYY/MM/DD HH:mm:ss",
"min_uptime": "60s",
"max_restarts": 30,
"autorestart": true,
"restart_delay": "60"
}
}
```
5. 使用apt安装JDK8，请自行百度。**下面的操作都使用root权限，才不会出错。**
6. 接下来使用pm2启动管理Judger-SandBox和JudgeServer，当然可用别的方式启动jar包，nohup之类的都可以，记住Judger-SandBox默认占用5050端口，JudgeServer占用8088端口，请确认不会被其它进程占用！本次介绍使用pm2管理启动：
- 更新`apt-get`
```shell
sudo apt-get update
```
- 安装`nodeJs`
```shell
sudo apt-get install nodejs
```
- 安装`npm`
```shell
sudo apt-get install npm
```
- 安装`pm2`
```shell
sudo npm install -g pm2
```
- 查看帮助,看到提示就说明成功了
```sehll
pm2 --help
```
7. 使用了第5步的就可以启动判题服务和判题安全沙盒了，操作如下：
- 启动沙盒，确保不要出错，不然无法进行自身题目判题（远程虚拟判题vj无影响）,Judger-SandBox为文件名，即是刚刚上传的。
```shell
pm2 start Judger-SandBox
```
- 查看是否正常,status的状态是online就是正常
```shell
pm2 list
```
- 启动判题服务，JudgeServer.json是我们在第四步配置创建放在与jar包同个文件夹里面的json文件，启动后也使用`pm2 list`查看
```shell
pm2 start JudgeServer.json
```
- 如果两者pm2 list里面的status都是online则说明此次判题服务部署成功。
8. 最后一步，下载对应编译语言的编译器，HOJ默认支持 GCC,G++,Python2,Python3,Java,Golang,C#编程语言，请自行百度下载对应的编译器。
### 2. 前端部署
1. 下载本项目，git clone或者download zip
2. 前提是本地有vue-cli4，请自行百度下载
3. 进入/hoj-vue文件夹，修改生产环境下的后端服务地址
![在这里插入图片描述](https://img-blog.csdnimg.cn/2021041616214988.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80Mzg1MzA5Nw==,size_16,color_FFFFFF,t_70)
4. 然后在当前路径运行打包命令
```powershell
npm run build
```
5. 打包成功会在src同文件夹内有个dist文件夹，复制里面的html和css等静态文件，上传到服务器的指定文件夹内/hoj/www/html内
6. 配置nginx，在安装好nginx后，修改nginx.conf配置
```shell
sudo vi /etc/nginx/nginx.conf
```
7. 将下面的内容复制进去
```json
server{
listen 80;
server_name www.hcode.top; # 此处填写你的域名或IP
root /hoj/www/htm; # 此处填写你的网页根目录
location /api{
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://localhost:6688; # 填写你的后端地址和端口
}
location ~ .*\.(js|json|css)$ {
gzip on;
gzip_static on; # gzip_static是nginx对于静态文件的处理模块，该模块可以读取预先压缩的gz文件，这样可以减少每次请求进行gzip压缩的CPU资源消耗。
gzip_min_length 1k;
gzip_http_version 1.1;
gzip_comp_level 9;
gzip_types text/css application/javascript application/json;
root /hoj/www/html; # 此处填写你的网页根目录
}
location / { # 路由重定向以适应Vue中的路由
index index.html;
try_files $uri $uri/ /index.html;
}
}
```
8. 修改后保存，然后重启或者热重载nginx，不出意外应该可用访问前端页面了。
```shell
sudo systemctl restart nginx
或
sudo nginx -s reload
```
