前言

本文借鉴文章：https://www.yuque.com/dengfenglai-esbap/kb/mc4k41?#xOxNG

在此基础上修改了一点（照着原来的做没成功），感谢这位师傅给的资源。

1、环境准备

1、主机：服务器CentOs7

2、Docker版本：20.10.2

3、Docker-compose版本：1.25.0

4、IP地址：公网地址或虚拟机地址

2、系统环境搭建

1、更新yum源

yum update

2、安装系统所需服务

yum install -y git nginx mariadb mariadb-server Mysql-python python-pip gcc  python-devel yum-utils device-mapper-persistent-data lvm2 epel-release

3、安装docker

# 换源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

# 安装docker
yum -y install docker-ce-17.12.1.ce

4、DaoClould配置镜像源加速

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io

5、检查是否安装成功

docker --version

6、安装docker-compose

# 下载docker compose
curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
# 添加可执行权限
chmod +x /usr/local/bin/docker-compose
# 将文件copy到 /usr/bin/目录下
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
# 查看版本
docker-compose --version

3、靶场环境搭建

1、下载CTFd

git clone https://github.com/glzjin/CTFd.git

2、下载frp

wget https://github.com/fatedier/frp/releases/download/v0.29.0/frp_0.29.0_linux_amd64.tar.gz

# 解压
tar -zxvf frp_0.29.0_linux_amd64.tar.gz

3、下载ctfd-whale插件

git clone https://github.com/glzjin/CTFd-Whale.git

# 重命名为小写
mv CTFd-Whale/ ctfd-whale

4、下载docker版本的frps

git clone https://github.com/glzjin/Frp-Docker-For-CTFd-Whale

# 重命名为小写
mv Frp-Docker-For-CTFd-Whale/ frp-docker-for-ctfd-whale

4、CTFd环境配置

1、初始化docker集群

docker swarm init

2、加入节点

docker node update --label-add='name=linux-1' $(docker node ls -q)

3、将ctfd-whale放入CTFd的插件目录

mv ctfd-whale/ CTFd/CTFd/plugins/

4、启动docker版本的frps及frps配置

cd frp-docker-for-whale/frp
vim frps.ini

进入之后，看到

[common]
bind_port = 6490
token = randomme

可将token进行修改，端口一般采用默认端口。

5、修改完成后返回目录启动

cd ..
docker-compose up -d

等待构建完成，用docker ps -a查看是否正在运行

6、将frpc文件移动到CTFd中

cd CTFd/
mkdir frpc

进入frpc的目录（frp_0.29.0_linux_amd64）将里面的frpc，frpc.ini，frpc_full.ini，LICENSE这四个文件放在CTFd/frpc文件夹中

cd ../frp_0.29.0_linux_amd64
mv frpc.ini ../CTFd/frpc/
mv frpc_full.ini ../CTFd/frpc/
mv frpc ../CTFd/frpc/
mv LICENSE ../CTFd/frpc/

7、进入刚刚新建的CTFd/fprc目录，配置frpc.ini文件

[common]
token = randomme
server_addr = 172.1.0.4
server_port = 6490
pool_count = 200
tls_enable = true

admin_addr = 172.1.0.3
admin_port = 7400

！除了token其他的务必和上面一摸一样

8、配置Dockerfile（这边做了一点修改）

FROM python:3.6-alpine
RUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.aliyun.com/g' /etc/apk/repositories &&\
    apk update && \
    apk add python3 python3-dev linux-headers libffi-dev gcc make musl-dev py-pip mysql-client git openssl-dev g++
RUN adduser -D -u 1001 -s /bin/bash ctfd
WORKDIR /opt/CTFd
RUN mkdir -p /opt/CTFd /var/log/CTFd /var/uploads
RUN python -m pip install --upgrade pip setuptools wheel -i https://pypi.doubanio.com/simple
RUN pip3 config set global.index-url https://pypi.doubanio.com/simple
RUN pip3 config set install.trusted-host pypi.doubanio.com
COPY requirements.txt .
RUN pip install -r requirements.txt -i  https://pypi.doubanio.com/simple
COPY . /opt/CTFd
RUN for d in CTFd/plugins/*; do \
      if [ -f "$d/requirements.txt" ]; then \
        pip install -r $d/requirements.txt -i  https://pypi.doubanio.com/simple; \
      fi; \
    done;
RUN chmod +x /opt/CTFd/docker-entrypoint.sh
RUN chown -R 1001:1001 /opt/CTFd
RUN chown -R 1001:1001 /var/log/CTFd /var/uploads
USER 1001
EXPOSE 8000
ENTRYPOINT ["/opt/CTFd/docker-entrypoint.sh"]

在原有的基础上加上了一行：

RUN python -m pip install --upgrade pip setuptools wheel -i https://pypi.doubanio.com/simple

9、配置docker-compose.yml

version: '2.2'

services:
  ctfd-nginx:
    image: nginx:1.17
    volumes:
      - ./nginx/http.conf:/etc/nginx/nginx.conf
    user: root
    restart: always
    ports:
      - "443:443"
    networks:
        default:
        internal:
    depends_on:
      - ctfd
    cpus: '1.00'
    mem_limit: 150M
  ctfd:
    build: .
    user: root
    restart: always
    ports:
      - "8000:8000"
    environment:
      - UPLOAD_FOLDER=/var/uploads
      - DATABASE_URL=mysql+pymysql://root:ctfd@db/ctfd
      - REDIS_URL=redis://cache:6379
      - WORKERS=1
      - LOG_FOLDER=/var/log/CTFd
      - ACCESS_LOG=-
      - ERROR_LOG=-
      - REVERSE_PROXY=true
    volumes:
      - .data/CTFd/logs:/var/log/CTFd
      - .data/CTFd/uploads:/var/uploads
      - .:/opt/CTFd:ro
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - db
    networks:
        default:
        internal:
        frp:
            ipv4_address: 172.1.0.2
    cpus: '1.00'
    mem_limit: 450M     

  db:
    image: mariadb:10.4
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=ctfd
      - MYSQL_USER=ctfd
      - MYSQL_PASSWORD=ctfd
    volumes:
      - .data/mysql:/var/lib/mysql
    networks:
        internal:
    command: [mysqld, --character-set-server=utf8mb4, --collation-server=utf8mb4_unicode_ci, --wait_timeout=28800, --log-warnings=0]
    cpus: '1.00'
    mem_limit: 750M     

  cache:
    image: redis:4
    restart: always
    volumes:
      - .data/redis:/data
    networks:
        internal:
    cpus: '1.00'
    mem_limit: 450M     

  frpc:
    image: glzjin/frp:latest
    restart: always
    volumes:
      - ./frpc:/conf/
    entrypoint:
        - /usr/local/bin/frpc
        - -c
        - /conf/frpc.ini
    networks:
        frp:
            ipv4_address: 172.1.0.3
        frp-containers:
    cpus: '1.00'
    mem_limit: 250M     

networks:
    default:
    internal:
        internal: true
    frp:
        driver: bridge
        ipam:
            config:
                - subnet: 172.1.0.0/16
    frp-containers:
        driver: overlay
        internal: true
        ipam:
            config:
                - subnet: 172.2.0.0/16

10、配置requirements.txt（这边我也做了点修改）

Flask==1.1.1
Werkzeug==0.16.0
Flask-SQLAlchemy==2.4.1
Flask-Caching==1.4.0
Flask-Migrate==2.5.2
Flask-Script==2.0.6
SQLAlchemy==1.3.11
SQLAlchemy-Utils==0.36.0
passlib==1.7.2
bcrypt==3.1.7
six==1.13.0
itsdangerous==1.1.0
requests>=2.20.0
PyMySQL==0.9.3
gunicorn==19.9.0
normality==2.0.0
dataset==1.1.2
mistune==0.8.4
netaddr==0.7.19
redis==3.3.11
datafreeze
python-dotenv==0.10.3

marshmallow-sqlalchemy==0.17.0
boto3==1.10.39
marshmallow==2.20.2
gevent==1.4.0
tzlocal==2.1

去掉了datafreeze的版本限制。

11、配置nginx

在CTFd的目录下，新建一个文件夹并进入

mkdir nginx
cd nginx

创建http.conf

worker_processes 4;
events {
  worker_connections 1024;
}
http {
  # Configuration containing list of application servers
  upstream app_servers {
    server ctfd:8000;
  }
  server {
    listen 80;
    client_max_body_size 4G;
    # Handle Server Sent Events for Notifications
    location /events {
      proxy_pass http://app_servers;
      proxy_set_header Connection '';
      proxy_http_version 1.1;
      chunked_transfer_encoding off;
      proxy_buffering off;
      proxy_cache off;
      proxy_redirect off;
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Host $server_name;
    }
    # Proxy connections to the application servers
    location / {
      proxy_pass http://app_servers;
      proxy_redirect off;
      proxy_set_header Host $host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Host $server_name;
    }
  }
}

12、开始构建

在CTFd文件夹下开始构建镜像和容器

cd CTFd/
docker-compose up -d

不出意外的话，可以看到

13、查看容器的运行状态

docker ps -a

可以看到

所有容器均启动成功

14、访问

浏览器中访问ip:8000即可打开
