Installing a Docker personal virtual machine under Linux

First, prepare an ISO file system, then load it with a virtual machine, and if you can't go to https://www.centos.org/download/

Guaranteed 64 for System kernel 3.0 or above

Many ways on the internet have not been possible, but this is the author of the pro-test feasible

First step: Check the kernel: uname-r

Yum update is possible if the kernel is not supported

Step two: Remove the old version and legacy files

$ sudo yum remove docker 
 docker-client                   
docker-client-latest                   
docker-common                   
docker-latest                   
docker-latest-logrotate                   
docker-logrotate                   
docker-selinux                   
docker-engine-selinux                   
docker-engine

Step Three: Install the required system Tools

-y yum-utils device-mapper-Persistent-data lvm2     

Fourth step: Add software source information

sudo yum-config---Add-repo http://mirrors.aliyun.com/docker-ce /linux/centos/docker-ce.repo 

Fifth step: Update the Yum cache

sudo yum makecache fast  

Sixth Step: Install Docker-ce

-y Install docker-ce  

Seventh step: Start the Docker backend service (stop if the service is stopped)

sudo systemctl start Docker 

Eighth step: To prevent Docker from shutting down after rebooting, you can set this

sudo systemctl Enabel Docker

So the installation is complete.
