安装GZ::CTF 一个开源的CTF角逐平台

系统：Ubuntu 20.04.4 Focal Fossa
配置apt镜像源，可到清华镜像站探求合适版本

1. sudo vi /etc/apt/sources.list

复制代码

以下为清华Ubuntu 20.04 LTS (focal)镜像源

1. # 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
2. deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
3. # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
4. deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
5. # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
6. deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
7. # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
9. deb http://security.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
10. # deb-src http://security.ubuntu.com/ubuntu/ focal-security main restricted universe multiverse
12. # 预发布软件源，不建议启用
13. # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
14. # # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse

更新软件源，漫长的时间……

1. sudo apt update

复制代码

更新完成之后安装docker和docker-compose

1. sudo apt install docker.io docker-compose

复制代码

利用下列命令查看版本判断是否安装成功

1. docker-compose -v

复制代码

docker-compose version 1.25.0, build unknown

1. docker -v

复制代码

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，起首创建一个GZCTF文件夹，根据文档创建配置appsettings.json和docker-compose.yml文件
appsettings.json

1. vi appsettings.json

复制代码
