centos離線安裝docker-ce 

      目前越來越多的應用采用docker部署管理，使快速的部署集成變得更容易。但筆者在安裝docker時，遇到一個問題，目標服務器無法聯網，這就要求我們能夠采用離線的方式安裝docker。下面就如何離線安裝docker，列出了實施步驟，與大家一起分享。

1. 系統環境

   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. 在可以聯網的機器上制作docker本地安裝源

    3.1 安裝一個虛擬機，然后在虛擬機里面安裝centos7（當然，也可以一台可以聯網安裝了centos7系統的主機）

    3.2 創建離線包存放目錄,並賦予讀寫權限

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

   3.3  創建docker的yum repository

   3.3 下載離線docker-ce依賴包

     注意，下面指令僅僅下載離線包到指定目錄。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安裝docker-ce依賴包及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下載離線docker-ce安裝包

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

 3.8 獲取安裝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

下載密匙文件(存放到/home/docker/local下)

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

 3.9 初始化安裝源repodata庫

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

 此時，/home/docker/local下面應該有如下安裝包、文件及目錄

1. container-selinux-2.42-1.gitad8f0f7.el7.noarch.rpm
2. createrepo-0.9.9-28.el7.noarch.rpm

3.10 打包導出安裝源

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

docker-local.tar.gz這個文件，就是我們制作好的離線安裝源。

4.將docker-local.tar.gz copy到無法聯網的centos7 服務器上(比如/home/docker/local目錄下)，並解壓

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

5 安裝createrepo

1. # cd /home/docker/local
2. # rpm -ivh createrepo-0.9.9-28.el7.noarch.rpm (這個rpm安裝包就是上面我們離線下載的安裝包)

6 備份安裝源

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

7 配置離線安裝源

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 構建本地安裝源

# createrepo -d /home/docker/local/repodata# yum clean all (清除緩存)

# yum makecache (創建緩存)

9 檢查本地庫是否制作成功

# yum repolist

repo id                                             repo

name                                                 status

docker                                               docker

local                                               38

repolist: 38

10. 安裝docker-ce

# yum install docker-ce

11.檢查是否安裝成功

1. # systemctl start docker
2. # docker version
