Docker----CentOS7系统上docker-compose的安装

一、按照官方文档推荐的安装方式

（1）下载docker-compose

执行如下命令进行下载

curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

若速度较慢，可以使用如下命令：

curl -L "https://mirror.ghproxy.com/https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

（2）修改目录权限

chmod +x /usr/local/bin/docker-compose

（3）创建软连接

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

（4）验证安装是否完成

执行如下命令，如果可以正常显示版本号，则表示已经完成

docker-compose --version

二、使用pip install 的方式安装

因为docker-compose是使用python开发的，因此可以通过pip install 的方式安装

（1）首先需要确保pip已经安装完成，如下

如下，表示pip为基于python3.9的版本，这里最好安装基于python3.6以上的pip

[root@iZbp1flzt6x7pxmxfhmxeeZ ~]# pip3 --version
pip 21.2.4 from /usr/local/python3/lib/python3.9/site-packages/pip (python 3.9)
[root@iZbp1flzt6x7pxmxfhmxeeZ ~]#

（2）升级pip的版本

python3 -m pip install --upgrade pip

如：

[root@iZbp1flzt6x7pxmxfhmxeeZ ~]# python3 -m pip install --upgrade pip

（3）安装docker-compose

pip3 install docker-compose

（4）验证是否安装完成

docker-compose -version

如下

[root@iZbp1flzt6x7pxmxfhmxeeZ ~]# docker-compose -version
docker-compose version 1.29.2, build unknown
[root@iZbp1flzt6x7pxmxfhmxeeZ ~]#
