Docker 是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的 Linux 机器上，也可以实现虚拟化。容器是完全使用沙箱机制，相互之间不会有任何接口。

1 Docker与虚拟机

安装docker时缺少依赖怎么办安装docker失败_操作系统_02

2 搭建过程

2.1 准备宿主系统

准备一个 CentOS 7操作系统，具体要求如下：

必须是 64 位操作系统

建议内核在 3.8 以上

通过以下命令查看您的 CentOS 内核：

# uname -r

2.2 安装Docker

# yum install docker

可使用以下命令，查看 Docker 是否安装成功：

# docker version

若输出了 Docker 的版本号，则说明安装成功了，可通过以下命令启动 Docker 服务：

# systemctl start docker.service

一旦 Docker 服务启动完毕，就可以开始使用 Docker 了。

yum安装时出现：Cannot retrieve metalink for repository: epel. Please verify its path and try again

在CentOS 6.3 x86_64下安装php-mcrypt的时候出现了问题：Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again，需要安装epel源。

解决方法：一句话：把vi /etc/yum.repos.d/epel.repo，文件第3行注释去掉，把第四行注释掉。具体如下：将第六行的disabled改成为0 即disabled=1改成disabled=0

打开/etc/yum.repos.d/epel.repo，将

[epel]
name=ExtraPackagesforEnterpriseLinux6- $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

修改为

[epel]
name=ExtraPackagesforEnterpriseLinux6- $basearch
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

再清理源，重新安装

yum clean all
yum install -y 需要的包

如果还是不行，修改DNS,到/etc/resolv.conf下添加一下：

nameserver 8.8.8.8
search localdomain

然后重启network服务：service network restart

最近在群里听说Docker很火，于是自己抱着试试的态度，想玩玩，可是遇到了一些问题，记录下来，方便备忘，也方便防止大家被坑。

我的虚拟机装的是centos 6.5,百度了好多教程，丫的，都不解释，就一句命令：yum install docker-io,这句话是用源安装docker,可是源一般是国外源，用这个命令因为GFW被墙，根本安装不了。

总共尝试了好几次，所谓的镜像很不稳定，不是没有找到，就是找到了，下了一半就中途断了，哎，网上总是说一句话搞定，可是一句话搞定要有前提呀，于是乎，我看了开源中国的docker更新记录
