docker-compose: 未找到命令
安装docker-compose
1.从github上下载docker-compose二进制文件安装
sudo curl -L https://github.com/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
若是github访问太慢，可以用daocloud下载，下载文件到/usr/local/bin/docker-compose文件夹下：
sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
添加可执行权限
sudo chmod +x /usr/local/bin/docker-compose
测试安装结果
docker-compose --version
