安装 Docker Compose 可以通过下面命令自动下载适应版本的 Compose
sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
问题
curl: (35) Peer reports incompatible or unsupported protocol version.
更新nss,curl
yum update nss curl
1.首先检查linux有没有安装python-pip包，终端执行 pip -V
pip -V
2.没有python-pip包就执行命令 yum -y install epel-release
3.执行成功之后，再次执行yum -y install python-pip
4.对安装好的pip进行升级 pip install --upgrade pip
5.pip安装好了，执行pip -V 再次检查pip环境
6.安装Docker-Compose pip --default-timeout=200 install -U docker-compose
7.检查docker-compose 安装：docker-compose -version
如果报错：
pkg_resources.DistributionNotFound: backports.ssl-match-hostname>=3.5
解决方法
pip install --upgrade backports.ssl_match_hostname
