centos安裝最新版的docker-ce(二進制安裝)
本文轉自於https://www.jianshu.com/p/87a84097e635
在centos上安裝過docker的都知道,yum install docker ,這種方式安裝的docker,最新版的centos系統上,版本應該是1.13.1,而目前最新版的docker到了18.03.0了。那麼怎麼安裝最新版的docker-ce呢?
1、系統要求
Linux操作系統內核要不低於3.10,並且要支持systemd。
2、下載最新版的docker
Docker官網下載地址:https://download.docker.com/linux/static/stable/x86_64/
上面列出了docker-ce版本,根據自己需要下載對應版本的docker-ce.

我下載的是18.03.0版本。
3、安裝部署方式說明
整個安裝部署過程大致可分爲將介質解壓出docker目錄、將可執行文件copy到/usr/bin目錄並設置權限、設置docker的systemd設定文件、設定docker服務開機啓動等。
方便的是,已經有志願者將所有安裝命令整理成一個腳本,直接下載下來執行即可。

4、安裝部署
1、上傳文件並設置執行權限,將腳本和文件放在同一級目錄。
chmod +x install-docker.sh # 授予可執行權限
2、執行安裝命令
./install-docker.sh docker-18.03.0-ce.tgz
安裝過程最後,腳本會執行docker version命令來顯示docker的版本。
