docker: Cannot connect to the Docker daemon at unix

问题·如下

[root@echohye ~]# docker run hello-world
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
See 'docker run --help'.      

看问号就知道什么问题了

docker没启动呀

service docker start      

一些常用的docker命令：

​sudo systemctl start docker​

​

Docker启动命令2: ​

​

​

docker关闭命令1: ​

​sudo systemctl stop docker​

​

docker关闭命令2: ​

​sudo service docker stop​

​

守护进程重启: ​

​sudo systemctl daemon-reload​

​

设置Docker开机自启动方式1: ​

​systemctl enable docker.service​

​

设置Docker开机自启动方式2: ​

​chkconfig docker on​

​
