The objective is to install Docker engine on Redhat 7 Linux using native docker script.


Internet connection as well as a privileged access to your Redhat 7 Linux is required.




  • # – requires given command to be executed with root privileges either directly as a root user or by use of sudo command
  • $ – given command to be executed as a regular non-privileged user


Install docker

Installation of docker using a native docker script is one command, straight forward process. Before you run the below docker installation command ensure that curl package is installed on your system:


yum  -y remove  docker-common docker container-selinux docker-selinux docker-engine


yum -y install lvm2 device-mapper device-mapper-persistent-data device-mapper-event device-mapper-libs device-mapper-event-libs

# curl --version
curl 7.29.0 (x86_64-redhat-linux-gnu)

Once ready, install docker using curl command which will download and execute a native docker installation script:

# curl -sSL https://get.docker.com/ | sh
+ sh -c 'sleep 3; yum -y -q install docker-engine'

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  sudo usermod -aG docker your-user

Remember that you will have to log out and back in for this to take effect!

Enable and Start docker

To enable docker to start on your Redhat 7 Linux after reboot run the following command:

# systemctl enable docker
Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service.

To start docker daemon run:

# systemctl start docker
