安装GZ::CTF 一个开源的CTF比赛平台

系统：Ubuntu 20.04.4 Focal Fossa

配置apt镜像源，可到清华镜像站寻找合适版本

sudovi /etc/apt/sources.list

以下为清华Ubuntu 20.04 LTS (focal)镜像源

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释

更新软件源，漫长的时间……

sudoapt update 

更新完成之后安装docker和docker-compose

sudoaptinstall docker.io docker-compose

使用下列命令查看版本判断是否安装成功

docker-compose-v

docker-compose version 1.25.0, build unknown

docker-v

Docker version 24.0.5, build 24.0.5-0ubuntu1~20.04.1

接下来到GZ:CTF根据文档部署，首先创建一个GZCTF文件夹，根据文档创建配置appsettings.json和docker-compose.yml文件

appsettings.json

vi appsettings.json

  "ForwardedOptions":{"ForwardedHeaders":5,

    "TrustedNetworks":["192.168.12.0/8"]}}

docker-compose.yml

vi docker-compose.yml

version: "3.0"
services:
  gzctf:
    image: gztime/gzctf:latest
    restart: always
    environment:
      - "LANG=zh_CN.UTF-8"# choose your backend language `en_US` / `zh_CN` / `ja_JP`
      - "GZCTF_ADMIN_PASSWORD=<Your GZCTF_ADMIN_PASSWORD>"
    ports:
      - "80:8080"
    volumes:
      - "./data/files:/app/files"
      - "./appsettings.json:/app/appsettings.json:ro"# - "./kube-config.yaml:/app/kube-config.yaml:ro" # this is required for k8s deployment
      - "/var/run/docker.sock:/var/run/docker.sock"# this is required for docker deployment
    depends_on:
      - db
 
  db:
    image: postgres:alpine
    restart: always
    environment:
      - "POSTGRES_PASSWORD=<Your POSTGRES_PASSWORD>"
    volumes:
      - "./data/db:/var/lib/postgresql/data"

搞完之后启动

sudodocker-compose up -d

就完成了，根据服务器对应IP访问即可
