docker探索-在centos6.5中安装docker（三）

1、要求

• centos6.5中需要64位
• centos6.5的linux内核需要3.x(centos的内核是2.6)

2、查看当前系统的位数和版本

[root@jacky jacky]# uname -r
2.6.32-431.el6.x86_64
[root@jacky jacky]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m

说明当前版本是centos6.5 64位系统

3、 安装yum优先级插件

#yum installyum-priorities

4、 安装epel

# rpm -Uvh http://mirrors.ustc.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

5、查看是否安装epel成功

# rpm -q epel-release

6、导入key

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

7、修改/etc/yum.repos.d/epel.repo文件，在最后添加一条属性 priority=11

# vim /etc/yum.repos.d/epel.repo

8、重建缓存

yum makecache

9、安装完成之后，确保yum list能找到Docker的相关rpm包

[root@jacky jacky]# yum list | grep docker
docker-io.x86_64                          1.7.1-2.el6                  @epel

[root@jacky jacky]# 

10、升级内核

11、安装docker

#yum install docker-io

12、更新device-mapper-libs

# yum upgrade device-mapper-libs

13、启动docker

[root@jacky jacky]# service docker service

14、设置docker开机自启动

#chkconfig docker on

15、测试

[root@jacky jacky]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

18、查看docker版本

[root@jacky jacky]# docker --version
Docker version 1.7.1, build 786b29d/1.7.1

安装成功
