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
 ······
 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
······
Complete!

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
