centos7 安裝docker

1,查看系統版本

cat /etc/redhat-release 

2，安裝gcc

yum -y install gcc
yum -y install gcc-c++

3，卸載舊版本

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

4，安裝須要的軟件包

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

5，設置stable鏡像倉庫位置

這裏使用阿里雲的鏡像

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

6，更新docker軟件包索引

yum makecache fast

7，安裝dockerce

yum -y install docker-ce

8，啓動docker

systemctl start docker

9，配置阿里雲鏡像加速

https://cr.console.aliyun.com/#/accelerator

①，vim /etc/docker/daemon.json

{
  "registry-mirrors": ["https://il675ldd.mirror.aliyuncs.com"]
}

②，重啓docker
