After the system is installed, the virtual machine can access the downlink address direct download
https://download.docker.com/linux/static/stable/x86_64/
After downloading
tar -xvf docker-18.06.3-ce.tgz (just unzip the downloaded file)
Copy the file to extract the good / usr / bin directory
cp docker / * / usr / bin
will be registered as a docker-Service
Vim /etc/systemd/system/docker.service
the following configurations applied and saved docker.service

Start
chmod + x /etc/systemd/system/docker.service # Adding file permissions and start Docker
systemctl daemon-heavy-duty unit # reload the configuration file
systemctl start docker # start Docker

In the virtual machine can use git to download
https://github.com/docker/compose/releases/
can also use Baidu cloud disk download
Download the file directly to the / usr / local / bin directory, or can be copied to this directory
sudo chmod + x / usr / local / bin / docker-compose (docker-compose your downloaded file)
sudo ln -s / usr / local / bin / docker-compose / usr / bin / docker-compose
Then you can test to see if the installation was successful
docker-compose --version (you download the docker-compose the file name)
docker docker-compose it and installed a
