安装 python-pip
1、首先检查linux有没有安装python-pip包，终端执行 pip -V
| 1 2 |
[root@vm-50-151 network-scripts]# pip -V
-bash: pip: command not found
|
2、没有python-pip包就执行命令 yum -y install epel-release
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 |

检查docker-compose 安装：docker-compose -version
| 1 2 |
[root@vm-50-151 network-scripts]# docker-compose -version
docker-compose version 1.17.1, build 6d101fb
|
如果报错：
| 1 |
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
如若python版本过低，需升级，见：http://www.cnblogs.com/YatHo/p/8257387.html
