问题

yum -y install docker-ce

会报错No package docker-ce available

安装环境

也可以通过在终端中输入以下命令，进行查看

uname -r
2.6.32-754.el6.x86_64

Docker 运行在 CentOS 7 上，要求系统为64位、系统内核版本为 3.10 以上。

Docker 运行在 CentOS-6.5 或更高的版本的 CentOS 上，要求系统为64位、系统内核版本为 2.6.32-431 或者更高版本

cat /etc/redhat-release
CentOS release 6.10 (Final)

环境准备

首先要确认yum是可用的，如果可用，可跳过环境准备步骤。

cd /etc/yum.repos.d

该目录下有两个重要的文件，CentOS-Base.repo和epel.repo

如果没有，可以下载或者新建文件

下载

执行命令：

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

新建文件

使用touch命令

touch CentOS-Base.repo

CentOS-Base.repo文件（供参考）

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#

touch epel.repo

epel.repo文件（主要是对enable的修改）

baseurl=http://mirrors.aliyun.com/epel/6/$basearch

接下来就是清理和重新生成缓存

yum clean all
yum makecache
