CentOS7中安装Docker-Compose

# 1. 前言 #

--------------------

前段时间使用 Docker 部署了 SpringBoot 以及一些关联应用，不过都是单独部署的各个容器；如果项目需要部署到多套环境中，则每套环境中都需要重复性的启用容器并关联容器，这样的部署方式就显得很繁琐；于是在这种情况下，就可以使用到 Docker 三剑客之 Docker-Compose。

# 2. 用处 #

--------------------

Docker-compose 实则就是把所有容器描述、端口映射、配置映射以及依赖关系等系列配置写在了一个配置文件中，也就好似一个批处理脚本，极大的提升了部署的速度。

# 3. 安装 #

--------------------

## 3.1 安装 docker ##

## 3.2 安装 python-pip ##

    升级 pip
    
    ---
    
    [root@cdy ~]# pip install --upgrade pip

    ---
    
    再次查看 pip 版本
    
    ---
    
    [root@cdy ~]# pip -V

    上面的操作都是在阿里云服务器中完成的，而最近在本地虚拟机中安装的时候出现了超时的问题，下面来设置一下阿里云的安装源
    
    ---
    
    ---
    
    在用户主目录下创建 .pip 目录
    
    ---
    
    [root@cdy ~]# mkdir ~/.pip && cd ~/.pip/
    
    ---
    
    再新建并编辑 pip.conf 配置文件
    
    ---
    
    [root@cdy .pip]# vim pip.conf
    
    ---
    
    粘贴如下配置信息来设置阿里云的安装源
    
    ---
    
    [global]
    index-url=http://mirrors.aliyun.com/pypi/simple/
    
    [install]
    trusted-host=mirrors.aliyun.com
    
    ---
    
    轮流输入命令 esc -> shift + 冒号 -> wq -> 回车，保存退出。最后再次升级 pip

## 3.3 安装 docker-compose ##

    安装 docker-compose
    
    ---
    
    [root@cdy ~]# pip install docker-compose==1.24.1

    [root@cdy ~]# docker-compose --version

    docker-compose version 1.24.1, build 4667896
    
    ---
    
    最后看起来有一些版本不兼容问题，接下来卸载不兼容模块，重新安装

    再次查看 docker-compose 版本
    
    ---
    
    [root@cdy /]# docker-compose --version
    docker-compose version 1.24.1, build 4667896

# 4. 常用命令 #

--------------------

*  查看版本信息：**docker-compose --version**

以下命令需要在有 docker-compose.yaml 文件的目录下执行；在写法上与 docker 命令类似

*  启动：**docker-compose up -d**
 *  停止：**docker-compose stop**
 *  停止并删除：**docker-compose down**
 *  查看构建的镜像：**docker-compose images**
 *  查看运行的容器：**docker-compose ps -a**

# 5. 扩展 #
