centos6.7 Installing Docker

First, view the system version

[Email protected] ~]# cat/etc/redhat-release CentOS release 6.7 (Final)

　　

Second, installation Epel

1. Enter CENTOS6 series Epel

Http://download.fedoraproject.org/pub/epel/6/i386/repoview/epel-release.html

　　

2. wget download

[[email protected] ~]# wget http://download.fedoraproject.org/pub/epel/6/i386/ Epel-release-6-8.noarch.rpm--2015-09-10 17:50:49--http://download.fedoraproject.org/pub/epel/6/i386/ EPEL-RELEASE-6-8.NOARCH.RPM Parsing host download.fedoraproject.org ... 67.219.144.68, 209.132.181.16, 66.35.62.162, ...

3.RPM installation Epel (I have installed, so the display has been installed)

[Email protected] ~]# RPM-IVH epel-release-6-8.noarch.rpmwarning:epel-release-6-8.noarch.rpm:header V3 RSA/SHA256 Signature, key ID 0608b895:nokeypreparing ...                ########################################### [100%]package Epel-release-6-8.noarch is already installed

4. After installing the Epel source, use the Yum command to check whether to add to the source list

[email protected] ~]# yum repolist loaded plugin: Fastestmirror, refresh-packagekit, securityloading mirror speeds from Cached Hostfile * base:centos.ustc.edu.cn * epel:mirror01.idc.hinet.net * extras:mirrors.163.com * updates:mirrors.163                                                                                 . com Warehouse Identity warehouse name                                                                           State base CentOS-6-base 6,575*epel Extra Packages for Enterprise Linu X 6-x86_64 11,766extras CentOS-6-                                           Extras 35updates CentOS-6-Updates 298repolist:18,67 4

5.bingo, has been added. To cache.

Third, disable SELinux

1. View SELinux Status

[[email protected] ~]# Cat/etc/selinux/config # This file controls the state of SELinux in the system.# selinux= can take One of these three values:#     enforcing-selinux security policy is enforced.# permissive-selinux prints warning     s instead of enforcing.#     disabled-no SELinux policy is loaded. selinux=enforcing# Selinuxtype= can take one of these, values:#     targeted-targeted processes is protected,#     

2. Modify the configuration file to replace enforcing with disabled

[[email protected] ~]# Cat/etc/selinux/config # This file controls the state of SELinux in the system.# selinux= can take One of these three values:#     enforcing-selinux security policy is enforced.# permissive-selinux prints warning     s instead of enforcing.#     disabled-no SELinux policy is loaded. selinux=disabled# Selinuxtype= can take one of these, values:#     targeted-targeted processes is protected,#     

3.reboot reboot the system to make it effective.

Four, ready to install Docker-io, touch the DA.

Attention:

I'm not upgrading the system kernel here.

[Email protected] ~]# uname-r2.6.32-573.3.1.el6.x86_64

The official Docker document says Linux kernel are required to be at least 3.8.

Warning is present when you run Docker in a new terminal daemon mode.

But now I can use it normally.
