2:、添加软件源信息：
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+’ /etc/yum.repos.d/docker-ce.repo
[root@localhost ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo Loaded plugins: fastestmirror adding repo from: https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo grabbing file https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo repo saved to /etc/yum.repos.d/docker-ce.repo [root@localhost ~]# sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
3、快读更新缓存并安装Docker-CE(默认安装最新的软件版本)：yum makecache fast && yum install -y docker-ce

4、 开启Docker服务并配置服务自启动：systemctl start docker.service && systemctl enable docker.service
[root@localhost ~]# systemctl start docker.service && systemctl enable docker.service Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.
5、验证Docker服务安装状态：
[root@localhost ~]# systemctl status docker.service #查看服务运行状态

配置阿里云Docker镜像加速器提升获取Docker官方镜像的速度：控制台>>产品与服务>>弹性计算>>容器镜像服务>>镜像中心>>镜像加速器
1、修改daemon配置文件(/etc/docker/daemon.json)来使用加速器
[root@localhost ~]# ll /etc/docker/
total 4
-rw------- 1 root root 244 Feb 27 23:46 key.json
[root@localhost ~]# tee /etc/docker/daemon.json <<-'EOF'
> {
> "registry-mirrors": ["https://96x8i0tt.mirror.aliyuncs.com"]
> }
> EOF
{
"registry-mirrors": ["https://96x8i0tt.mirror.aliyuncs.com"]
}
[root@localhost ~]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://96x8i0tt.mirror.aliyuncs.com"]
}
2、重载Daemon配置文件并重启Docker服务：systemctl daemon-reload && systemctl restart docker.service
[root@localhost ~]# systemctl daemon-reload && systemctl restart docker.service
安装指定版本的Docker-CE（可选）
1、查找Docker-CE的版本：yum list docker-ce.x86_64 –showduplicates | sort -r
[root@localhost ~]# yum list docker-ce.x86_64 --showduplicates | sort -r * updates: mirrors.aliyun.com Loading mirror speeds from cached hostfile Loaded plugins: fastestmirror Installed Packages * extras: mirrors.aliyun.com docker-ce.x86_64 3:20.10.3-3.el7 docker-ce-stable docker-ce.x86_64 3:20.10.3-3.el7 @docker-ce-stable docker-ce.x86_64 3:20.10.2-3.el7 docker-ce-stable docker-ce.x86_64 3:20.10.1-3.el7 docker-ce-stable docker-ce.x86_64 3:20.10.0-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.9-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.8-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.7-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.6-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.5-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.4-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.3-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.2-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.15-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.14-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.1-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.13-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.12-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.11-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.10-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.0-3.el7 docker-ce-stable * base: mirrors.aliyun.com Available Packages
2、安装指定版本的Docker-CE：yum -y install docker-ce-[VERSION] #(VERSION例如列表中的19.03.9-3.el7)
[root@localhost ~]# yum -y install docker-ce-19.03.9-3.el7
