一、docker在CentOS 6上的安装
Docker仅支持64位系统，对于centos 6系统可以使用epel库安装docker，命令如下：
#yum -y install http://mirrors.yun-idc.com/epel/6/i386/epel-release-6-8.noarch.rpm
#yum -y install docker-io
例如：
|
# yum -y install http://mirrors.yun-idc.com/epel/6/i386/epel-release-6-8.noarch.rpm Loaded plugins: fastestmirror Determining fastest mirrors * base: mirror.bit.edu.cn * extras: mirrors.btte.net * updates: mirror.bit.edu.cn base | 3.7 kB 00:00 extras | 3.4 kB 00:00 extras/primary_db | 29 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 2.0 MB 00:00 Setting up Install Process epel-release-6-8.noarch.rpm | 14 kB 00:00 Examining /var/tmp/yum-root-Peszrf/epel-release-6-8.noarch.rpm: epel-release-6-8.noarch Marking /var/tmp/yum-root-Peszrf/epel-release-6-8.noarch.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:6-8 will be installed --> Finished Dependency Resolution Dependencies Resolved ========================================================================================================================================================================================================== Package Arch Version Repository Size ========================================================================================================================================================================================================== Installing: epel-release noarch 6-8 /epel-release-6-8.noarch 22 k Transaction Summary ========================================================================================================================================================================================================== Install 1 Package(s) Total size: 22 k Installed size: 22 k Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Warning: RPMDB altered outside of yum. ** Found 12 pre-existing rpmdb problem(s), 'yum check' output follows: ant-1.7.1-13.el6.x86_64 has missing requires of java-devel >= ('0', '1.5.0', None) 1:ecj-3.4.2-6.el6.x86_64 has missing requires of java-gcj-compat 1:ecj-3.4.2-6.el6.x86_64 has missing requires of java-gcj-compat sinjdoc-0.5-9.1.el6.x86_64 has missing requires of java-gcj-compat >= ('0', '1.0.70', None) sinjdoc-0.5-9.1.el6.x86_64 has missing requires of java-gcj-compat >= ('0', '1.0.70', None) sinjdoc-0.5-9.1.el6.x86_64 has missing requires of java_cup >= ('0', '0.10', None) xerces-j2-2.7.1-12.6.el6_0.x86_64 has missing requires of java-gcj >= ('0', '1.5.0', None) xerces-j2-2.7.1-12.6.el6_0.x86_64 has missing requires of java-gcj >= ('0', '1.5.0', None) xml-commons-apis-1.3.04-3.6.el6.x86_64 has missing requires of java-gcj-compat xml-commons-apis-1.3.04-3.6.el6.x86_64 has missing requires of java-gcj-compat xml-commons-resolver-1.1-4.18.el6.x86_64 has missing requires of java-gcj-compat xml-commons-resolver-1.1-4.18.el6.x86_64 has missing requires of java-gcj-compat Installing : epel-release-6-8.noarch 1/1 Verifying : epel-release-6-8.noarch 1/1 Installed: epel-release.noarch 0:6-8 Complete! |

检查并启动docker： # rpm -qa|grep epel epel-release-6-8.noarch # rpm -qa|grep docker docker-io-1.7.1-2.el6.x86_64 # service docker status docker is stopped # service docker start Starting cgconfig service: [ OK ] Starting docker: [ OK ] |
二、Docker在centos 7上的安装
对于centos 7系统，由于centos-extras源中已内置docker，可以直接使用yum进行安装：
#yum -y install docker
