一、前言
最近在一个集群上安装 Docker,本来多么简单的事却因为网络原因以及系统版本变得曲折了,也由于找到了不适合的解决方案,饶了一个弯,所以特此记录一下安装过程,防止重复踩坑。==系统版本:Centos 7.2.1511==
二、下载与上传
由于服务器不能连接外网,所以服务器使用的是公司自带的 yum 仓库,但是仓库内没有 Docker 安装包,所以需要自己下载。下载地址:https://yum.dockerproject.org/repo/main/centos/7/Packages/
下载文件:
docker-engine-1.13.1-1.el7.centos.x86_64.rpm
docker-engine-selinux-1.13.1-1.el7.centos.noarch.rpm
下载完成后,上传到服务器等待安装
三、安装
依次输入如下命令:$ sudo yum -y localinstall docker-engine-selinux-1.13.1-1.el7.centos.noarch.rpm $ sudo yum -y localinstall docker-engine-1.13.1-1.el7.centos.x86_64.rpm
这里使用
yum -y localinstall命令,而不是
rpm -ivh,是因为它会自动从仓库中下载并安装相应的依赖包,那么如果指定的仓库中有系统对应的版本,安装就应该是没问题的,但是我所使用的仓库中没有
7.2.1511版本的安装包,在该目录下有一个
readme文件(通过浏览器打开),内容如下:
This directory (and version of CentOS) is deprecated. For normal users, you should use /7/ and not /7.2.1511/ in your path. Please see this FAQ concerning the CentOS release scheme: https://wiki.centos.org/FAQ/General If you know what you are doing, and absolutely want to remain at the 7.2.1511 level, go to http://vault.centos.org/ for packages. Please keep in mind that 7.2.1511 no longer gets any updates, nor any security fix's.
嗯,大概意思就是让我使用版本7目录下的…
==由于对应版本的安装包不存在时发生的异常见附录1==
四、修改 yum 获取的版本
使用如下命令进入修改界面:sudo vi /etc/yum.repos.d/CentOS-Base.repo
原文件如下:
[base] name=CentOS-$releasever - Base baseurl=http://s7repo01/centos/7.2.1511/os/$basearch/ gpgcheck=1 gpgkey=http://s7repo01/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates baseurl=http://s7repo01/centos/7.2.1511/updates/$basearch/ gpgcheck=1 gpgkey=http://s7repo01/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras baseurl=http://s7repo01/centos/7.2.1511/extras/$basearch/ gpgcheck=1 gpgkey=http://s7repo01/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus baseurl=http://s7repo01/centos/7.2.1511/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://s7repo01/centos/RPM-GPG-KEY-CentOS-7
将所有的
baseurl属性修改为版本7对应的目录路径,
baseurl属性修改后如下:
baseurl=http://s7repo01/centos/7/centosplus/$basearch/
注:只修改版本号即可,对应的仓库地址可能与此不同,能访问则不必修改。
五、继续安装
继续使用如下命令安装:$ sudo yum -y localinstall docker-engine-selinux-1.13.1-1.el7.centos.noarch.rpm $ sudo yum -y localinstall docker-engine-1.13.1-1.el7.centos.x86_64.rpm
如果出现某个仓库不能连接的情况,可使用如下命令禁用掉,例(查看具体的错误信息可获知仓库名称,这里是
dockerrepo):
sudo yum-config-manager --disable dockerrepo
重新输入命令,安装成功

使用
rpm命令安装,可看见需要的依赖包
sudo rpm -ivh docker-engine-selinux-1.13.1-1.el7.centos.noarch.rpm warning: docker-engine-selinux-1.13.1-1.el7.centos.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID 2c52609d: NOKEY error: Failed dependencies: policycoreutils-python is needed by docker-engine-selinux-1.13.1-1.el7.centos.noarch selinux-policy-base >= 3.13.1-102 is needed by docker-engine-selinux-1.13.1-1.el7.centos.noarch selinux-policy-targeted >= 3.13.1-102 is needed by docker-engine-selinux-1.13.1-1.el7.centos.noarch
