Docker-Compose

需要先安装好docker

1、关闭防火墙

sudo systemctl stop firewalld

2、下载二进制文件

从 GitHub 下载最新版 Docker Compose 的二进制文件：

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

国内加速下载（解决 GitHub 访问慢的问题）：

# 使用 FastGit 镜像
sudo curl -L "https://hub.fgit.cf/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose# 或使用 ghproxy 代理
sudo curl -L "https://ghproxy.com/https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
