centos安装最新版的docker-ce（二进制安装）

本文转自于https://www.jianshu.com/p/87a84097e635

在centos上安装过docker的都知道，yum install docker ，这种方式安装的docker，最新版的centos系统上，版本应该是1.13.1，而目前最新版的docker到了18.03.0了。那么怎么安装最新版的docker-ce呢？

1、系统要求

Linux操作系统内核要不低于3.10，并且要支持systemd。

2、下载最新版的docker

Docker官网下载地址：https://download.docker.com/linux/static/stable/x86_64/

上面列出了docker-ce版本，根据自己需要下载对应版本的docker-ce.

我下载的是18.03.0版本。

3、安装部署方式说明

整个安装部署过程大致可分为将介质解压出docker目录、将可执行文件copy到/usr/bin目录并设置权限、设置docker的systemd设定文件、设定docker服务开机启动等。
方便的是，已经有志愿者将所有安装命令整理成一个脚本，直接下载下来执行即可。

4、安装部署

1、上传文件并设置执行权限，将脚本和文件放在同一级目录。

chmod +x install-docker.sh  # 授予可执行权限

2、执行安装命令

./install-docker.sh  docker-18.03.0-ce.tgz
安装过程最后，脚本会执行docker version命令来显示docker的版本。
