CentOS-6.5離線安裝docker-1.7教程

CentOS-6.5離線安裝docker-1.7教程 0.  準備

本文是類比實際上線時，沒有網路的情況下使用rpm包安裝docker-1.7的方法。不過安裝中也是使用yum，相比較直接使用rpm安裝，yum可以解決一些庫檔案的依賴關係。

# cd /etc/yum.repos.d/

# mkdir bak

# mv * bak/

1.  安裝libcgroup

# cd cgroup/

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

2.  安裝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.  安裝docker

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

4.  更新device-mapper-libs

# yum installdevice-mapper-*

5.    設定開機自啟

# chkconfig docker on 6.    檢查支援情況

# lxc-checkconfig 7.    啟動cgroup

# service cgconfig start

8.  啟動docker

9.  測試

# docker ps –a
