centos7 安裝 docker 容器

 

本文采用yum install 的方式來安裝docker

第一步：安裝yum安裝配置工具（如果直接可以下載阿里雲對應的docker-ce.repo此步驟一、二、三可以省略）

$ sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

第二步:生成yum安裝docker的配置文件

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

第三步:替換docker-ce.repo 裏邊的內容，主要目的是解決牆的問題

vi /etc/yum.repos.d/docker-ce.repo

將“https://download-stage.docker.com/”全部替換爲“https://mirrors.aliyun.com/docker-ce/”

 第四步：

sudo yum install docker-ce

第五步:驗證
