[Docker] docker install[1]CentOS7如何在国内流畅的安装Docker

CentOS7 Docker CE安装

做了一些调整修改,方便国内安装docker

 

准备工作

系统要求

Docker CE 支持 64 位版本 CentOS 7,并且要求内核版本不低于 3.10。

CentOS 7 满足最低内核的要求,但由于内核版本比较低,部分功能(如 overlay2 存储层驱动)无法使用,并且部分功能可能不太稳定。

卸载旧版本

旧版本的 Docker 称为 docker 或者 docker-engine,使用以下命令卸载旧版本:

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

使用 yum 安装

执行以下命令安装依赖包:

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

由于某些网络问题,建议使用国内源。

 

$ sudo yum-config-manager \
    --add-repo \
    https://mirrors.ustc.edu.cn/docker-ce/linux/centos/docker-ce.repo


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

强烈建议使用国内源http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

以前可以直接用这个repo,但是现在这个repo有问题,如果repo里面包含aliyun,就可以用,否则就要换掉。
