CentOS6.8上Docker的安装

一、查看系统版本

目前,CentOS 仅发行版本中的内核支持 Docker。
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。
[root@CentOS6 ~]# uname -a
Linux CentOS6.8 2.6.32-642.el6.x86_64 #1 SMP Tue May 10 17:27:01 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
[root@CentOS6 ~]# cat /etc/redhat-release
CentOS release 6.8 (Final)

二、安装Docker

  1. Docker使用EPEL发布,RHEL系的OS首先要确保已经持有EPEL仓库,否则先检查OS的版本,然后安装相应的EPEL包。
RHEL:Red Hat公司发布的面向企业用户的Linux操作系统。
yum install -y epel-release

2. 执行命令:

yum install -y docker-io

然而:报错了

[root@CentOS6 ~]# yum install -y docker-io

No package docker-io available.

搜了各种答案,总结如下:

解决办法1:

yum没有找到docker包,更新epel第三方软件库,运行命令:

sudo yum install epel-release 

之后再执行:

sudo yum install docker

然而我的却还是报错。

解决办法2:

Ubuntu/Debian: curl -sSL https://get.docker.com | sh

Linux 64bit binary: https://get.docker.com/builds/Linux/x86_64/docker-1.7.1

Darwin/OSX 64bit client binary: https://get.docker.com/builds/Darwin/x86_64/docker-1.7.1

Darwin/OSX 32bit client binary: https://get.docker.com/builds/Darwin/i386/docker-1.7.1

Linux 64bit tgz: https://get.docker.com/builds/Linux/x86_64/docker-1.7.1.tgz

Windows 64bit client binary: https://get.docker.com/builds/Windows/x86_64/docker-1.7.1.exe

Windows 32bit client binary: https://get.docker.com/builds/Windows/i386/docker-1.7.1.exe

Centos 6/RHEL 6: https://get.docker.com/rpm/1.7.1/centos-6/RPMS/x86_64/docker-engine-1.7.1-1.el6.x86_64.rpm

Centos 7/RHEL 7: https://get.docker.com/rpm/1.7.1/centos-7/RPMS/x86_64/docker-engine-1.7.1-1.el7.centos.x86_64.rpm

Fedora 20: https://get.docker.com/rpm/1.7.1/fedora-20/RPMS/x86_64/docker-engine-1.7.1-1.fc20.x86_64.rpm

Fedora 21: https://get.docker.com/rpm/1.7.1/fedora-21/RPMS/x86_64/docker-engine-1.7.1-1.fc21.x86_64.rpm

Fedora 22: https://get.docker.com/rpm/1.7.1/fedora-22/RPMS/x86_64/docker-engine-1.7.1-1.fc22.x86_64.rpm

yum install docker-io,该命令是用源安装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

yum install https://get.docker.com/rpm/1.7.1/centos-6/RPMS/x86_64/docker-engine-1.7.1-1.el6.x86_64.rpm

此时:成功安装

3.安装后的配置文件

 [root@CentOS6 ~]# ls -l /etc/sysconfig/docker 
-rw-r--r--. 1 root root 199 Jul 15  2015 /etc/sysconfig/docker

4. 启动Docker后台服务

service docker start

5. Docker Version验证

docker version
