Status: Downloaded newer image for hello-world:latest

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

操作完成，希望这一次复制粘贴能助您快速开启 docker 之旅。

 One of the configured repositories failed (Unknown),
 and yum doesn''t have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won''t use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

CentOS 7 系统 安装docker及docker compose 组件

1 概述

本章将详细介绍在CentOS7.0系统下如何安装docker，分为在线安装和离线安装两部分。目前，CentOS仅发行版本中的内核支持Docker。推荐使用CentOS 7.0及以上版本，64位操作系统、系统内核版本为3.10以上。

2 在线安装Docker

1）首先查看CentOS版本是否要求。若不符合版本要求，请升级系统版本

cat /etc/redhat-release

2）安装依赖包

yum install -y yum-utils device-mapper-persistent-data lvm2

3）添加软件源信息

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

4）更新yum缓存

yum makecache fast

5）安装Docker-CE

yum -y install docker-ce

6）启动docker后台服务

systemctl start docker

7）查验docker是否安装成功

docker version

8）安装docker-compose

curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

9）赋执行权限

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

10）查验docker-compose是否安装成功

docker-compose version

12）设置docker服务开机自启动

systemctl enable docker

3 离线安装Docker

1）获取docker离线安装包，形如centos-local.tgz压缩包。（请联系我获取）

2）将离线包上传到服务器的root目录下

3）进入root目录，解压.tgz包

cd /root
tar -xvzf centos-local.tgz

4）安装createrepo

cd /root/docker-ce-local
rpm -ivh createrepo-0.9.9-28.el7.noarch.rpm

5）新增docker-ce-local.repo源文件，写入以下内容

vi /etc/yum.repos.d/docker-ce-local.repo

[docker-ce-local]

　　name=Local Yum

　　baseurl=file:///root/docker-ce-local/

　　gpgcheck=1

　　gpgkey=file:///root/docker-ce-local/gpg

　　enabled=1

6）生成源索引及缓存

createrepo /root/docker-ce-local
yum makecache

7）安装docker-ce

yum install docker-ce

8）启动并测试

systemctl start docker
docker version

9）加入开机自启

systemctl enable docker

10）安装docker-compose

cp /root/docker-ce-local/docker-compose /usr/bin/

11）赋执行权限

chmod +x /usr/bin/docker-compose

12）验证版本

docker-compose version

CentOS 8.0 64位安装Docker 以及 Docker Compose

curl -L https://github.com/docker/compose/releases/download/1.8.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

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