一、查看系统版本
[root@localhost ~]# cat /etc/redhat-release CentOS release 6.7 (Final)
二、安装EPEL
1.进入centos6系列EPEL下载地址
http://download.fedoraproject.org/pub/epel/6/i386/repoview/epel-release.html
images/loading.gif' data-original="http://images2015.cnblogs.com/blog/638371/201509/638371-20150910104939997-1096324906.png" width="1078" height="295" />
2. wget下载
[root@localhost ~]# wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm--2015-09-10 17:50:49-- http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm正在解析主机 download.fedoraproject.org... 67.219.144.68, 209.132.181.16, 66.35.62.162, ...正在连接 download.fedoraproject.org|67.219.144.68|:80... 已连接。已发出 HTTP 请求，正在等待回应... 302 Found位置：http://mirrors.opencas.cn/epel/6/i386/epel-release-6-8.noarch.rpm [跟随至新的 URL]--2015-09-10 17:50:50-- http://mirrors.opencas.cn/epel/6/i386/epel-release-6-8.noarch.rpm正在解析主机 mirrors.opencas.cn... 159.226.11.160, 2001:cc0:2004:1:225:90ff:fe00:fe8b, 2001:cc0:2004:1:225:90ff:fe3a:e6b5正在连接 mirrors.opencas.cn|159.226.11.160|:80... 已连接。已发出 HTTP 请求，正在等待回应... 200 OK长度：14540 (14K) [application/x-redhat-package-manager]正在保存至: “epel-release-6-8.noarch.rpm”100%[=======================================================================================================>] 14,540 12.9K/s in 1.1s 2015-09-10 17:50:56 (12.9 KB/s) - 已保存 “epel-release-6-8.noarch.rpm” [14540/14540])
3.rpm安装EPEL(我已经安装过了，所以显示已经安装了)
[root@localhost ~]# rpm -ivh epel-release-6-8.noarch.rpmwarning: epel-release-6-8.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID 0608b895: NOKEYPreparing... ########################################### [100%] package epel-release-6-8.noarch is already installed
4.安装好EPEL 源后，用yum 命令来检查是否添加到源列表
root@localhost ~]# yum repolist已加载插件：fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * epel: mirror01.idc.hinet.net * extras: mirrors.163.com * updates: mirrors.163.com仓库标识 仓库名称 状态base CentOS-6 - Base 6,575*epel Extra Packages for Enterprise Linux 6 - x86_64 11,766extras CentOS-6 - Extras 35updates CentOS-6 - Updates 298repolist: 18,674
5.bingo，已经添加。进行缓存。
[root@localhost ~]# yum makecache已加载插件：fastestmirror, refresh-packagekit, securityLoading mirror speeds from cached hostfileCould not get metalink https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64 error was12: Timeout on https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=x86_64: (28, 'Operation too slow.

三、禁用selinux
1.查看selinux状态
[root@localhost ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing - SELinux security policy is enforced.# permissive - SELinux prints warnings instead of enforcing.# disabled - No SELinux policy is loaded.SELINUX=enforcing# SELINUXTYPE= can take one of these two values:# targeted - Targeted processes are protected,# mls - Multi Level Security protection.SELINUXTYPE=targeted
2.修改该配置文件中将enforcing替换为disabled
[root@localhost ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system.# SELINUX= can take one of these three values:# enforcing - SELinux security policy is enforced.# permissive - SELinux prints warnings instead of enforcing.# disabled - No SELinux policy is loaded.SELINUX=disabled# SELINUXTYPE= can take one of these two values:# targeted - Targeted processes are protected,# mls - Multi Level Security protection.SELINUXTYPE=targeted
3.reboot重启一下系统，使生效。
四、准备就绪，安装docker-io，摸摸哒。
[root@localhost ~]# yum install docker-io已加载插件：fastestmirror, refresh-packagekit, security设置安装进程Loading mirror speeds from cached hostfile * base: mirrors.hust.edu.cn * epel: ftp.cuhk.edu.hk * extras: mirrors.163.com * updates: mirrors.163.com解决依赖关系--> 执行事务检查---> Package docker-io.x86_64 0:1.7.1-2.el6 will be 安装--> 处理依赖关系 lxc，它被软件包 docker-io-1.7.1-2.el6.x86_64 需要--> 处理依赖关系 libcgroup，它被软件包 docker-io-1.7.1-2.el6.x86_64 需要--> 执行事务检查---> Package libcgroup.x86_64 0:0.40.rc1-16.el6 will be 安装---> Package lxc.x86_64 0:1.0.7-2.el6 will be 安装--> 处理依赖关系 lua-lxc(x86-64) = 1.0.7-2.el6，它被软件包 lxc-1.0.7-2.el6.x86_64 需要--> 处理依赖关系 lua-alt-getopt，它被软件包 lxc-1.0.7-2.el6.x86_64 需要--> 处理依赖关系 liblxc.so.1()(64bit)，它被软件包 lxc-1.0.7-2.el6.x86_64 需要--> 执行事务检查---> Package lua-alt-getopt.noarch 0:0.7.0-1.el6 will be 安装---> Package lua-lxc.x86_64 0:1.0.7-2.el6 will be 安装--> 处理依赖关系 lua-filesystem，它被软件包 lua-lxc-1.0.7-2.el6.x86_64 需要---> Package lxc-libs.x86_64 0:1.0.7-2.el6 will be 安装--> 执行事务检查---> Package lua-filesystem.x86_64 0:1.4.2-1.el6 will be 安装--> 完成依赖关系计算依赖关系解决================================================================================================================================================= 软件包 架构 版本 仓库 大小=================================================================================================================================================正在安装: docker-io x86_64 1.7.1-2.el6 epel 4.6 M为依赖而安装: libcgroup x86_64 0.40.rc1-16.el6 base 129 k lua-alt-getopt noarch 0.7.0-1.el6 epel 6.9 k lua-filesystem x86_64 1.4.2-1.el6 epel 24 k lua-lxc x86_64 1.0.7-2.el6 epel 15 k lxc x86_64 1.0.7-2.el6 epel 120 k lxc-libs x86_64 1.0.7-2.el6 epel 250 k事务概要=================================================================================================================================================Install 7 Package(s)总下载量：5.1 MInstalled size: 20 M确定吗？[y/N]：
还需要我解释么，一路y下去。
启动我们的宝贝docker
[root@localhost ~]# /etc/init.d/docker startStarting cgconfig service: [确定]Starting docker: [确定]
查看docker进程
[root@localhost ~]# ps -ef | grep dockerroot 3602 1 0 18:26 pts/0 00:00:00 /usr/bin/docker -droot 3745 3429 0 18:27 pts/0 00:00:00 grep docker
查看安装的docker版本
Status: Downloaded newer image for centos:latest[root@localhost ~]# docker versionClient version: 1.7.1Client API version: 1.19Go version (client): go1.4.2Git commit (client): 786b29d/1.7.1OS/Arch (client): linux/amd64Server version: 1.7.1Server API version: 1.19Go version (server): go1.4.2Git commit (server): 786b29d/1.7.1OS/Arch (server): linux/amd64
注意：
我在这里并没有升级系统内核
[root@localhost ~]# uname -r2.6.32-573.3.1.el6.x86_64
docker官方文档说要求Linux kernel至少3.8以上。
在一个新的终端里守护模式运行docker时，会出现warning
[root@localhost ~]# docker -dWARN[0000] You are running linux kernel version 2.6.32-573.3.1.el6.x86_64, which might be unstable running docker. Please upgrade your kernel to 3.10.0.
但是目前表示我可以正常使用。
