1. Download package:

https://download.docker.com/linux/static/stable/x86_64/

I chose docker-18.06.3-ce.tag under x86

[root@zzl ~]# wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.3-ce.tgz

Note: You can change stable (stable version) to nightly or test!
For nightly and test, please refer to the official website introduction:

2. Unzip the package and move the binary file to a directory on the executable path:

tar zxvf docker-18.06.3-ce.tgz

sudo cp docker/* /usr/bin/

3. Start the docker daemon:

sudo dockerd &

If you want to use other options to start the daemon, please create and edit the file "/etc/docker/daemon.json"

Then just check the docker startup status, and run a container to view the results!
