CentOS7下安装Docker-Compose
CentOS7下安装Docker-Compose
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
1 [root@vm-50-151 network-scripts]# pip -V
2 -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

4、对安装好的pip进行升级 pip install --upgrade pip
(我在这一步出现错误：提示说让You should consider upgrading via the ‘python -m pip install --upgrade pip’ command.输入python -m pip install --upgrade pip命令升级pip版本。但是输入之后仍然不可以。)
直接命令：**pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip==20.1.1**升级，会给出一个命令：执行即可。
[root@centos7 etc]# pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pip==20.2.2
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support
Looking in indexes: https://pypi.tuna.tsinghua.edu.cn/simple

至此，pip安装好了，执行pip -V 再次检查pip环境。
[root@centos7 etc]# pip -V
pip 20.2.2 from /usr/lib/python2.7/site-packages/pip (python 2.7)
[root@centos7 etc]#
安装Docker-Compose
出现此错误:
ERROR: Could not find a version that satisfies the requirement websocket-client<1,>=0.32.0 (from docker-compose) (from versions: none) ERROR: No matching distribution found for websocket-client<1,>=0.32.0 (from docker-compose)
使用pip安装其他模块时也可能出现上述错误，主要原因是网络的问题，需要使用国内的镜像源来加速，比如豆瓣源
因此命令可以使用：
pip install docker-compose -i http://pypi.douban.com/simple/ --trusted-host pypi.douban.com
即可成功安装。
