CentOS安装docker

安装依赖包：

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

安装docker

$ sudo yum install docker

安装完成之后运行下面的命令，查看是否安装成功

docker version
or
docker info

或

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

可能是docker没有启动造成的，运行下面的命令重启docker

sudo systemctl start docker

或

sudo service docker restart

启动Docker-CE

$ sudo systemctl enable docker
$ sudo systemctl start docker
