CentOS7 docker-engine 徹底離線安裝

本地CentOS依賴包下載（有網絡環境）

• yum只下載不安裝依賴包

$ yum install --downloadonly --downloaddir=/root/download <package-name>

• 建立依賴包所在的yum repo目錄

$ mkdir -p /root/download

• 默認狀況下，下載的rpm包位於如下位置：/var/cache/yum/x86_64/7

$ ll /var/cache/yum/x86_64/7
drwxr-xr-x 4 root root 4096 Dec 19 03:28 base
drwxr-xr-x 4 root root 4096 Dec 19 03:28 extras
-rw-r--r-- 1 root root  117 Dec 19 03:31 timedhosts
-rw-r--r-- 1 root root  381 Dec 19 03:31 timedhosts.txt
drwxr-xr-x 4 root root 4096 Dec 19 03:28 updates

• 獲取createrepo安裝包

$ yum install --downloadonly --downloaddir=/root/download createrepo

• 獲取更新yum源

$ yum update --downloadonly --downloaddir=/root/download

• 獲取nginx安裝包

$ vi /etc/yum.repos.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=0
enabled=1

$ yum install --downloadonly --downloaddir=/root/download nginx

• 建立docker安裝源

$ tee /etc/yum.repos.d/docker.repo <<-'EOF'
[dockerrepo]
name=Docker Repository
baseurl=https://yum.dockerproject.org/repo/main/centos/7/
enabled=1
gpgcheck=1
gpgkey=https://yum.dockerproject.org/gpg
EOF
$ yum --downloadonly --downloaddir=/root/download install docker-engine

• 設置平時yum安裝軟件時不刪除安裝包

$ vi /etc/yum.conf
keepcache=1

• 安裝createrepo

$ yum install createrepo

• 初始化yum源的repodata

$ createrepo -pdo /root/download /root/download
$ createrepo --update /root/download

---

把依賴複製到徹底離線環境

• 把yum獲取的rpm文件保存到yum-repo

• 把yum-repo複製到離線環境的CentOS的/yum-repo目錄

CentOS徹底離線環境docker-engine安裝（無網絡環境）

• 移除默認的yum repo配置

$ cd /etc/yum.repos.d
$ ll
-rw-r--r-- 1 root root 1664 Nov 29 18:12 CentOS-Base.repo
-rw-r--r-- 1 root root 1309 Nov 29 18:12 CentOS-CR.repo
-rw-r--r-- 1 root root  649 Nov 29 18:12 CentOS-Debuginfo.repo
-rw-r--r-- 1 root root  630 Nov 29 18:12 CentOS-Media.repo
-rw-r--r-- 1 root root 1331 Nov 29 18:12 CentOS-Sources.repo
-rw-r--r-- 1 root root 2893 Nov 29 18:12 CentOS-Vault.repo
-rw-r--r-- 1 root root  314 Nov 29 18:12 CentOS-fasttrack.repo
$ mkdir bak
$ mv CentOS-* bak

• 進行yum客戶端配置

$ vi /etc/yum.repos.d/localyum.repo
[localyum]
name=localyum
baseurl=file:///yum-repo
enable=1
gpgcheck=0

• 進行yum源更新

$ yum clean all
$ yum makecache

• 進行yum更新

$ yum update

• yum update後會自動生成CentOS-*文件，務必刪除

$ cd /etc/yum.repos.d
$ mv CentOS-* bak

• 安裝createrepo

$ yum install createrepo

• 安裝nginx

$ yum install nginx

• 設置nginx的訪問路徑指向自定義yum源目錄

$ vi /etc/nginx/conf.d/default.conf
    location / {
        root   /yum-repo;
        autoindex  on;
        index  index.html index.htm;
    }

• 重啓nginx

$ nginx -s reload

• 驗證nginx設置

$ curl -L localhost

• yum客戶端配置，設置baseurl爲http://localhost

$ vi /etc/yum.repos.d/localyum.repo
baseurl=http://localhost

• 進行yum源更新

$ yum clean all
$ yum makecache

• 驗證yum源

$ yum search docker-engine
$ yum install docker-engine

• 若是/root/download下有新增的rpm安裝包，請使用如下命令更新repo

$ createrepo --update /root/download
