Centos6.7安装docker1.7.1
时间:2016-06-06 00:17 来源:linux.it.net.cn 作者:IT
Docker当前发布的最新版本已经到了1.11，其官网上针对Centos的的安装需求如下:
Docker requires a 64-bit installation regardless of your CentOS version. Also, your kernel must be 3.10 at minimum, which CentOS 7 runs.
看来如果我们想在低于3.x内核的操作系统（比如Centos6.7）上装Docker最新版，势必要升级内核了。且不说升级内核步骤繁琐、容易出错，单就这种比较怪异的搭配：Centos6.x + Kerneol3.X + Docker1.11，就没有人能够保证其稳定性。故我的建议是设法在Centos6.7上安装较低版本的Docker。事实上，对于内核版本要大于3.10这个要求，是从Docker1.8.2版本开始的，Docker之前的版本是可以运行在较低内核版本之上的，比如1.7.1。
首先，看下我的操作环境以及直接安装Docker的现象：
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-573.el6.x86_64 #1 SMP Thu Jul 23 15:44:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)
[root@localhost ~]# docker
-bash: docker: command not found
[root@localhost ~]# yum install docker

可以看到，在Centos6.7的标准yum源中已经没有Docker的安装包了，这时，我们需要安装EPEL。
EPEL（Extra Packages for Enterprise Linux），企业版Linux额外包，RHEL分布非标准包的社区类库。安装如下：
[root@localhost ~]# rpm -iUvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

接下来安装Docker1.7.1，在1.7.1中，安装包名称为docker-io，故我们的安装命令如下：
[root@localhost ~]# yum install docker-io
