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
安装 python-pip
1、首先检查linux有没有安装python-pip包，终端执行 pip -V
[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
[root@vm-50-151 network-scripts]# yum -y install epel-release Loaded plugins: fastestmirror, langpacks base | 3.6 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/2): extras/7/x86_64/primary_db | 129 kB 00:00:05 (2/2): updates/7/x86_64/primary_db | 3.6 MB 00:00:09 Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.163.com * updates: mirrors.cn99.com Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:7-9 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================================================================================================= Package Arch Version Repository Size ======================================================================================================================================================================================================================= Installing: epel-release noarch 7-9 extras 14 k Transaction Summary ======================================================================================================================================================================================================================= Install 1 Package Total download size: 14 k Installed size: 24 k Downloading packages: epel-release-7-9.noarch.rpm | 14 kB 00:00:05 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : epel-release-7-9.noarch 1/1 Verifying : epel-release-7-9.noarch 1/1 Installed: epel-release.noarch 0:7-9 Complete!
3、执行成功之后，再次执行yum -y install python-pip
[root@vm-50-151 network-scripts]# yum install python-pip Loaded plugins: fastestmirror, langpacks epel/x86_64/metalink | 7.3 kB 00:00:00 epel | 4.7 kB 00:00:00 (1/3): epel/x86_64/group_gz | 261 kB 00:00:01 epel/x86_64/updateinfo FAILED 54% [=============================================- ] 165 kB/s | 3.9 MB 00:00:20 ETA http://ftp.riken.jp/Linux/fedora/epel/7/x86_64/repodata/ed160c344c46b2ec8d800367326ceaf25560b1515a0603a1e33a795b8b6492a1-updateinfo.xml.bz2: [Errno 12] Timeout on http://ftp.riken.jp/Linux/fedora/epel/7/x86_64/repodata/ed160c344c46b2ec8d800367326ceaf25560b1515a0603a1e33a795b8b6492a1-updateinfo.xml.bz2: (28, 'Operation too slow.

4、对安装好的pip进行升级 pip install --upgrade pip
[root@vm-50-151 network-scripts]# pip install --upgrade pip
Collecting pip

Uninstalling pip-8.1.2:
Successfully uninstalled pip-8.1.2
Successfully installed pip-9.0.1
至此，pip安装好了，执行pip -V 再次检查pip环境。
[root@vm-50-151 network-scripts]# pip -V pip 9.0.1 from /usr/lib/python2.7/site-packages (python 2.7)
安装Docker-Compose
1.终端执行：pip install docker-compose
报错：ReadTimeoutError: HTTPSConnectionPool(host='pypi.python.org', port=443): Read timed out
解决：pip --default-timeout=200 install -U docker-compose
[root@vm-50-151 network-scripts]# pip --default-timeout=200 install -U docker-compose

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