Centos

卸载旧版本

sudo yum remove docker \
  docker-client \
  docker-client-latest \
  docker-common \
  docker-latest \
  docker-latest-logrotate \
  docker-logrotate \
  docker-engine

存储库安装

安装yum-utils包（提供yum-config-manager 实用程序）并设置稳定存储库。

sudo yum install -y yum-utils

换源

标准源

sudo yum-config-manager  --add-repo https://download.docker.com/linux/centos/docker-ce.repo

阿里源

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

安装docker引擎

sudo yum install docker-ce docker-ce-cli containerd.io

或者是特定版本安装 列出版本

yum list docker-ce --showduplicates | sort -r

sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io

sudo systemctl start docker

RPM包安装

前往https://download.docker.com/linux/centos/ 并选择您的 CentOS 版本。然后浏览x86_64/stable/Packages/ 并下载.rpm要安装的 Docker 版本的文件。

sudo yum install /path/to/package.rpm

脚本安装

参考：https://github.com/docker/docker-install.git

curl -fsSL https://get.docker.com -o get-docker.sh

离线安装

下载离线包 (opens new window) 并自行上传到服务器解压

以下示例版本: docker-20.10.18

解压包

tar -zxvf docker-20.10.18.tgz

授权

chmod +x docker/*

复制到bin目录

cp docker/* /usr/bin/

创建包路径

mkdir -p /data/docker/lib 

默认路径 /var/lib/docker

编辑docker.service

vim /usr/lib/systemd/system/docker.service

加入以下内容，并保存

[Unit]
