Install-NVIDIA-driver-and-cudatoolkit-on-CentOS-7.md

+This instruction is based on CentOS7 and Nvidia driver.
+
+**Preparation**
+
+`yum -y update`  
+`yum -y groupinstall "Development Tools"`  
+`yum -y install kernel-devel`
+
+Download the latest NVIDIA driver for unix.  
+In order to have the NVIDIA drivers rebuilt automatically with future kernel updates you can also install the EPEL repository and the DKMS package. This is optional.
+
+`yum -y install epel-release`  
+`yum -y install dkms`
+
+**Reboot machine to make sure running the newest kernel**
+
+Edit `/etc/default/grub`. Append the following  to “`GRUB_CMDLINE_LINUX`”  
+`rd.driver.blacklist=nouveau`
+
+Generate a new grub configuration to include the above changes.  
+`grub2-mkconfig -o /boot/grub2/grub.cfg`
+
+Edit/create `/etc/modprobe.d/blacklist.conf` and append:  
+`blacklist nouveau`
+
+Backup your old initramfs and then build a new one  
+`mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img`  
+`dracut /boot/initramfs-$(uname -r).img $(uname -r)`
+
+**Reboot**
+
+The NVIDIA installer will not run while X is running so switch to text mode:  
+`systemctl isolate multi-user.target`
+
+Run the NVIDIA driver installer and enter yes to all options.  
+`sh NVIDIA-Linux-x86_64-*.run`
+
+**Reboot your machine**
+
+## Iinstall NVIDIA’s CUDA Toolkit
+
+Download the latest CUDA Toolkit
+
+**Run the CUDA installer.**  
+`sh cuda_*.run`  
+Say no to installing the NVIDIA driver. Use the default option for all other choices.
+
+**To add CUDA to your environment add the following files.**
+
+**Create** `**/etc/profile.d/cuda.sh**`  
+`PATH=$PATH:/usr/local/cuda/bin`  
+`export` `PATH`
+
+**Create** `**/etc/profile.d/cuda.csh**`  
+`set path = ( $path /usr/local/cuda/bin )`
+
+**Create** `**/etc/ld.so.conf.d/cuda.conf**`  
+`/usr/local/cuda/lib64`
+
+Install cuDNN
+
+*   download cuDNN
+*   extract tgz file
+
+sudo cp lib64/\* /usr/local/cuda/lib64/
+
+sudo cp include/\* /usr/local/cuda/include/
+
+sudo reboot
