Nvidia CUDA Toolkit supports CentOS 7 and it is relatively simple to install it. Nvidia provides three types of installation – a big setup file, a big rpm file and an official Nvidia repository, which we are going to use it in this article. The Nvidia repository contains the Nvidia video driver for the Nvidia video cards like GeForce, GTX, RTX and so on. You may need CUDA Toolkit if you are a game developer or you want to build yourself some of the mining software like XMR-STAK.
In this article, we are going to use the NVIDIA official repository for CUDA and the video driver module. There are other ways to install CUDA, which are not the purpose of this article. Using an official repository is the best practice for installing software on your system.
STEP 1) Update and install the NVIDIA official repository.
yum update -y yum install -y yum-utils yum-config-manager --add-repo http://developer.download.nvidia.com/compute/cuda/repos/rhel7/x86_64/cuda-rhel7.repo

[root@localhost ~]# yum clean all Loaded plugins: fastestmirror Cleaning repos: base cuda epel extras updates Cleaning up list of fastest mirrors
STEP 2) Install the CUDA and the NVIDIA video driver.
As you can see the driver uses DKMS – https://en.wikipedia.org/wiki/Dynamic_Kernel_Module_Support. In simple words, the DKMS allows installing kernel modules, which source does not reside in the kernel tree. NVIDIA uses proprietary video driver and DKMS to load the kernel module and the proprietary video driver.
yum -y install nvidia-driver-latest-dkms cuda
The above line will initiate the installation of around 209 packages including GNU GCC, mesa, perl, java (openjdk), Xorg server and multiple libraries and more. The total downloaded size is 2.4 Gbytes and installed size is 4.7 Gbytes. In the end, there is a section with the full installation log.
STEP 3) Enable the NVIDIA video driver.
At this stage, we have NVIDIA Cuda installed and ready for use, but in most cases, you probably would like to use the compiled code on the same computer, so you need the NVIDIA video driver loaded. The driver is just installed but cannot be used. We have to manually compile it once and after the first compile when updating the kernel it will compile the module automatically.
First install the last dependency:
[root@localhost ~]# yum install kernel-devel Loaded plugins: fastestmirror, nvidia #### NVIDIA #### Loading mirror speeds from cached hostfile * base: mirror.wwfx.net * epel: mirrors.neterra.net * extras: mirror.wwfx.net * updates: mirror.wwfx.net Resolving Dependencies --> Running transaction check ---> Package kernel-devel.x86_64 0:3.10.0-1062.1.1.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================================================ Package Arch Version Repository Size ============================================================================================================================================================================ Installing: kernel-devel x86_64 3.10.0-1062.1.1.el7 updates 18 M Transaction Summary ============================================================================================================================================================================ Install 1 Package Total download size: 18 M Installed size: 38 M Is this ok [y/d/N]: y Downloading packages: Delta RPMs disabled because /usr/bin/applydeltarpm not installed. kernel-devel-3.10.0-1062.1.1.el7.x86_64.rpm | 18 MB 00:00:02 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : kernel-devel-3.10.0-1062.1.1.el7.x86_64 1/1 Verifying : kernel-devel-3.10.0-1062.1.1.el7.x86_64 1/1 Installed: kernel-devel.x86_64 0:3.10.0-1062.1.1.el7 Complete!
Build the DKMS module:
[root@localhost ~]# dkms status nvidia, 418.87.00: added [root@localhost ~]# dkms build nvidia/418.87.00 Kernel preparation unnecessary for this kernel. Skipping... Building module: cleaning build area... 'make' -j2 module SYSSRC=/lib/modules/3.10.0-1062.1.1.el7.x86_64/build IGNORE_XEN_PRESENCE=1 IGNORE_PREEMPT_RT_PRESENCE=1 IGNORE_CC_MISMATCH=1..................... cleaning build area... DKMS: build completed. [root@localhost ~]# dkms status nvidia, 418.87.00, 3.10.0-1062.1.1.el7.x86_64, x86_64: built
Enable the driver by uncommenting the line:
options nvidia-drm modeset=1
in file – “/usr/lib/modprobe.d/nvidia.conf”. If the line is missing just add it at the end of the file. In the same file the there is a line “blacklist nouveau” to instruct the kernel not to load the open-source module for the NVIDIA video driver.
And then reboot the machine. After reboot, the NVIDIA driver will be loaded.
Check if the driver is loaded successfully:
[root@localhost ~]# dmesg|grep -i nvidia

If the driver is not loaded all of the above directories in /dev would be missing and the nvidia smi would report the driver is not loaded.
