== Preparing a CentOS 7 Instance == | |||
Nvidia provides repositories for various distributions, therefore the required software can be installed and maintained via these repositories. | |||
To compile the module sources from the nvidia repository, it is necessary to install dkms to automatically build the modules on kernel updates. | |||
It ensures that the GPU is still working after OS updates, dkms is provided in the EPEL repository and additionally the kernel headers and the kernel source needs to be installed | |||
before the nvidia driver can be set up. | |||
===== <u>Enabling the EPEL repository and install needed software</u> ===== | |||
<pre> | |||
[root@gpu-centos centos]# yum -y update && reboot | |||
yum -y install epel-release && yum -y install dkms kernel-devel-$(uname -r) kernel-headers-$(uname -r) | |||
</pre> | |||
===== <u>Adding the NVIDIA repository and install the driver package</u> ===== | |||
<pre> | |||
[root@gpu-centos centos]# yum-config-manager --add-repo http://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-rhel7.repo | |||
yum install -y cuda-drivers | |||
</pre> | |||
Nvidia uses it's own gpg key to sign it's packages, yum will ask to autoimport it. | |||

Is this ok [y/N]: y | |||
</pre> | |||
After the installation a reboot is required to properly load the module and create the nvidia device files. | |||
<pre> | |||
[root@gpu-centos ~]# ls -al /dev/nvidia* | |||
