Linux下安裝docker

https://www.cnblogs.com/xred/p/3845215.html

 中間碰到的問題：

一、ssl認證問題，直接安裝ca-certificates

二、yum命令很差使問題，redhat安裝yum

三、vm沒法連互聯網問題，修改vm的配置，改爲NAS

四、epel資源mirror錯誤問題，解決辦法是修改epel.conf路徑爲base。

名詞解釋

名詞	解釋	備註
Selinux	安全加強型 Linux（Security-Enhanced Linux）簡稱 SELinux。它是一個 Linux 內核模塊，也是 Linux 的一個安全子系統。
LXC	LXC爲Linux Container的簡寫;Linux Container容器是一種內核虛擬化技術，能夠提供輕量級的虛擬化，以便隔離進程和資源。LXC與docker的關係:（1）Docker並非LXC的替代品，Docker的底層就是使用了LXC來實現的。LXC將Linux進程沙盒化，使得進程之間相互隔離，而且可以控制各進程的資源分配。 （2）在LXC的基礎之上，Docker提供了一系列更強的功能
EPEL	EPEL的全稱叫 Extra Packages for Enterprise Linux 。EPEL是由 Fedora 社區打造，爲 RHEL 及衍生髮行版如 CentOS、Scientific Linux 等提供高質量軟件包的項目。裝上了 EPEL以後，就至關於添加了一個第三方源。
hop5.repo	Centos 6.x Package Repository http://www.hop5.in/yum/el6/repoview/

 

1、禁用selinux

因爲Selinux和LXC有衝突，因此須要禁用selinux。編輯/etc/selinux/config，設置兩個關鍵變量。   
SELINUX=disabled
SELINUXTYPE=targeted

2、配置Fedora EPEL源

1 sudo yum install http://ftp.riken.jp/Linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

3、添加hop5.repo源

 

cd /etc/yum.repos.d
sudo wget http://www.hop5.in/yum/el6/hop5.repo

4、安裝Docker
sudo yum install docker-io

1\執行安裝命令：

[root@guang ~]# yum install docker-io
