安装docker

1. linux(centos)安装docker

docker官网：https://docs.docker.com/engine/install/centos/

1.1 检查版本号

docker -v   #检查docker是否安装

1.2 删除之前的docker

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

1.3 配置yum源

cd /etc/yum.repos.d/
wget http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum repolist

liunx配置yum源终极攻略: https://developer.aliyun.com/mirror/centos-vault/?spm=a2c6h.25603864.0.0.2c30d00aR7wlZR

# 1. 查看centos版本
cat /etc/centos-release # 7.9.2009

# 2. 找到你需要的版本：https://mirrors.aliyun.com/centos-vault/?spm=a2c6h.25603864.0.0.2da26d2di6geyu
Index of /centos-vault/altarch/7.9.2009/extras/aarch64/

# 3. 根据版本进行文件替换，替换前，对所有repo文件进行备份
cd /etc/yum.repos.d 
备份

# 4. 将CentOS-Base.repo中的地址改为你找到的index
:%s/centos\/$releasever/centos-vault\/altarch\/7.9.2009/g 
%s/mirror.centos.org/mirrors.aliyun.com/g

# 5. 重新加载yum
yum clean all
yum makecache
yum repolist enabled

repo如下
