**centos****离线安装docker-ce **

目前越来越多的应用采用docker部署管理，使快速的部署集成变得更容易。但笔者在安装docker时，遇到一个问题，目标服务器无法联网，这就要求我们能够采用离线的方式安装docker。下面就如何离线安装docker，列出了实施步骤，与大家一起分享。

**1.** **系统环境**

Centos7  Linux version 3.10.0-327.10.1.el7.x86\_64

**2. docker-ce****版本**

18.03.0.ce-1.el7.centos.x86\_64

**3.** **在可以联网的机器上制作docker本地安装源**

3.1 安装一个虚拟机，然后在虚拟机里面安装centos7（当然，也可以一台可以联网安装了centos7系统的主机）

3.2 创建离线包存放目录,并赋予读写权限

1.  *\# mkdir -p /home/docker/local* 
2.  *\# chmod -R 777 /home/docker/local*

3.3  创建docker的yum repository

3.3 下载离线docker-ce依赖包

注意，下面指令仅仅下载离线包到指定目录。后面要用到。

1.  yum install *--downloadonly --downloaddir=/home/docker/local yum-utils \\*
2.    device-mapper-persistent-data \\
3.    lvm2 createrepo

3.4安装docker-ce依赖包及createrepo

1.  yum install yum-utils \\
2.    device-mapper-persistent-data \\
3.    lvm2 createrepo

3.5 配置docker repository

1.  yum-config-manager \\
2.      --add-repo \\
3.      https:*//download.docker.com/linux/centos/docker-ce.repo*

3.6 更新yum源索引

yum makecache fast

3.7下载离线docker-ce安装包

yum install *--downloadonly --downloaddir=/home/docker/local docker-ce*

3.8 获取安装docker需要的密匙

查看密匙文件url

1.  \[jerry@localhost ~\]$ more /etc/yum.repos.d/docker-ce.repo
2.  \[docker-ce-stable\]
3.  name=Docker CE Stable - $basearch
4.  baseurl=https://download.docker.com/linux/centos/7/$basearch/stable
5.  enabled=1
6.  gpgcheck=1
7.  gpgkey=https://download.docker.com/linux/centos/gpg
8.   
9.  \[docker-ce-stable-debuginfo\]
10. name=Docker CE Stable - Debuginfo $basearch
11. baseurl=https://download.docker.com/linux/centos/7/debug-$basearch/stable
12. enabled=0
13. gpgcheck=1
14. gpgkey=https://download.docker.com/linux/centos/gpg

下载密匙文件(存放到/home/docker/local下)

1.  cd /home/docker/local
2.  wget https:*//download.docker.com/linux/centos/gpg*

3.9 初始化安装源repodata库

1.  \# createrepo -pdo /home/docker/local /home/docker/local
2.  \# createrepo --update /home/docker/local

此时，/home/docker/local下面应该有如下安装包、文件及目录

1.  container-selinux-2.42-1.gitad8f0f7.el7.noarch.rpm
2.  createrepo-0.9.9-28.el7.noarch.rpm
3.  device-mapper-1.02.140-8.el7.x86\_64.rpm
4.  device-mapper-event-1.02.140-8.el7.x86\_64.rpm
5.  device-mapper-event-libs-1.02.140-8.el7.x86\_64.rpm

8.  docker-ce-18.03.0.ce-1.el7.centos.x86\_64.rpm
9.  dracut-033-502.el7\_4.1.x86\_64.rpm
10. dracut-config-rescue-033-502.el7\_4.1.x86\_64.rpm
11. dracut-network-033-502.el7\_4.1.x86\_64.rpm

3.10 打包导出安装源

*\# cd /home/docker/local*\# tar -zcvf docker-local.tar.gz \*

docker-local.tar.gz这个文件，就是我们制作好的离线安装源。

**4.****将docker-local.tar.gz copy到无法联网的centos7 服务器上(比如/home/docker/local目录下)，并解压**

1.  \# mkdir -p /home/docker/local （如果不存在此目录，则创建,然后copy docker-local.tar.gz到此目录）
2.  \# cd /home/docker/local
3.  \# tar -zxvf docker-local.tar.gz

**5** **安装createrepo**

1.  *\# cd /home/docker/local*
2.  *\# rpm -ivh createrepo-0.9.9-28.el7.noarch.rpm (**这个**rpm**安装包就是上面我们离线下载的安装包**)*

**6** **备份安装源**

1.  *\# cd /etc/yum.repos.d/*
2.  *\# mkdir repobak*
3.  *\# mv \* repobak/*

**7** **配置离线安装源**

1.  \# vi /etc/yum.repos.d/docker-ce-local.repo
2.  \[docker\]
3.  name=docker local
4.  baseurl=file:*///home/docker/local/*
5.  gpgcheck=0
6.  enabled=1
7.  gpgkey=file:*///home/docker/local/gpg*

**8** **构建本地安装源**

*\# createrepo -d /home/docker/local/repodata*\# yum clean all (清除缓存)

\# yum makecache (创建缓存)

**9** **检查本地库是否制作成功**

*\# yum repolist*

repo id                                             repo

name                                                 status

docker                                               docker

local                                               38

repolist: 38
