Docker-Compose是一个部署多个容器的简单但是非常必要的工具.安装Docker-Compose之前，请先安装 python-pip

一、安装 python-pip

[root@workbench-test ~]# pip -V
-bash: pip: command not found

[root@workbench-test ~]# yum install python-pip
[root@workbench-test ~]# yum -y install epel-release
[root@workbench-test ~]# yum install python-pip
[root@workbench-test ~]# pip install --upgrade pip

[root@workbench-test ~]# pip -V
pip 10.0.1 from /usr/lib/python2.7/site-packages/pip (python 2.7)

二、安装Docker Compose

[root@workbench-test ~]# pip install docker-compose
---------------------------------------------------------------------------------------
如果报错：
ReadTimeoutError: HTTPSConnectionPool(host='pypi.python.org', port=443): Read timed out
解决：
# pip --default-timeout=200 install -U docker-compose
--------------------------------------------------------------------------------------
如果执行中报错：
Setup script exited with error: command 'gcc' failed with exit status 1异常

这是没有正确安装Python开发环境导致，解决如下：
# yum install python-devel
# yum install libevent-devel
# pip install gevent
# yum install groupinstall 'development tools'
--------------------------------------------------------------------------------------

检验docker-compose是否安装成功
[root@workbench-test ~]# docker-compose --version
docker-compose version 1.21.2, build a133471
--------------------------------------------------------------------------------------
如果报错：
pkg_resources.DistributionNotFound: backports.ssl-match-hostname>=3.5
解决方法：更新backports.ssl-match-hostname的版本，在终端输入命令
# pip install --upgrade backports.ssl_match_hostname
