安装流程：
sudo curl -L "https://github.com/docker/compose/releases/download/1.22.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
但是docker-compose version还是出现命令找不到
执行以下命令即可解决
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
