Ubuntu deb 安装docker后无法启动

yxuqtr

　　相信很多使用Ubuntu安装docker的小伙伴都遇到过:安装号docker后,无法启动的尴尬场景.
　　按照官方文档,安装好docker后, 运行 sudo docker run hello-world.命令行提示:
　　

andre@andre-vm:~$ sudo docker run hello-world
Post http:///var/run/docker.sock/v1.20/containers/create: dial unix /var/run/docker.sock: no such file or directory.
* Are you trying to connect to a TLS-enabled daemon without TLS?
* Is your docker daemon up and running?
　　然后,....然后就没了,这可怎么办呢?, 经过复制, 粘贴, 搜索, 找到了一篇文章,顺利解决问题.我在这里记录一下,主要是备忘.
解决办法:
　　在命令行中运行:

$ sudo service docker start
　　得到如下提示信息,就OK啦:

docker start/running, process 6515
　　然后,就可以使用docker尽情的玩耍了....... 如:

docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
535020c3e8ad: Pull complete
af340544ed62: Pull complete
library/hello-world:latest: The image you are pulling has been verified. Important: image verification is a tech preview feature and should not be relied on to provide security.

Status: Downloaded newer image for hello-world:latest
Hello from Docker.
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
