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

GitCommit: de40ad0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[v_blue]安装指定版本的Docker-CE（可选）[/v_blue]
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
