一、安装Docker 设置centos yum镜像源

cd /etc/yum.repos.d/
mkdir backup && mv *repo backup/
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
yum clean all && yum makecache
yum repolist all

卸载旧版本(如果安装过旧版本的话)

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

安装需要的软件包yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
#设置yum源
yum-config-manager \ --add-repo \ https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo
yum makecache

安装docker

yum install -y docker-ce

启动docker

systemctl start docker

验证是否启动成功

docker version

设置docker开机自启

systemctl enable docker

验证开机自启是否设置成功

systemctl is-enabled docker

配置镜像加速

vim /etc/docker/daemon.json
#添加以下内容：
{ "registry-mirrors": [ "https://mirror.ccs.tencentyun.com" ] }　

重启docker

systemctl restart docker

二、通过rancher脚本一键快速安装docker

curl https://releases.rancher.com/install-docker/19.03.sh | sh
curl https://releases.rancher.com/install-docker/20.10.sh | sh
