CentOS-6.5离线安装docker-1.7教程

0.  准备

本文是模拟实际上线时，没有网络的情况下使用rpm包安装docker-1.7的方法。不过安装中也是使用yum，相比较直接使用rpm安装，yum可以解决一些库文件的依赖关系。

# cd /etc/yum.repos.d/

# mkdir bak

# mv * bak/

1.  安装libcgroup

# cd cgroup/

# yum installlibcgroup-0.40.rc1-16.el6.x86_64.rpm

2.  安装lxc

# yum installlua-filesystem-1.4.2-1.el6.x86_64.rpm lua-alt-getopt-0.7.0-1.el6.noarch.rpmlxc-libs-1.0.7-2.el6.x86_64.rpm lxc-1.0.7-2.el6.x86_64.rpmlua-lxc-1.0.7-2.el6.x86_64.rpm

3.  安装docker

# yum installdocker-io-1.7.1-2.el6.x86_64.rpm

4.  更新device-mapper-libs

# yum installdevice-mapper-*

5.    设置开机自启

# chkconfig docker on

6.    检查支持情况

# lxc-checkconfig

7.    启动cgroup

# service cgconfig start

8.  启动docker

9.  测试

# docker ps –a

10.        常见错误
