centos 7 安装docker-compose

1.下载docker-compose

# 官方推荐（太慢）
curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 国内（更快）
curl -L https://get.daocloud.io/docker/compose/releases/download/1.26.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

2.添加执行权限

chmod +x /usr/local/bin/docker-compose

3.查看版本

docker-compose version
