Nvidia GPU驱动升级(centos7.6)

操作步骤

1. 卸载旧驱动

   1	nvidia-uninstall

2. 重新创建initramfs

   1 2 3

   cd /boot mv initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak dracut -vf initramfs-$(uname -r).img $(uname -r)

3. 重启系统

4. 下载新驱动

   CUDA Toolkit 11.2 Downloads

   1	wget <https://developer.download.nvidia.com/compute/cuda/11.2.0/local_installers/cuda_11.2.0_460.27.04_linux.run>

5. 安装新驱动

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

   [root@VM-1-43-centos gpu]# sh cuda_11.2.0_460.27.04_linux.run =========== = Summary = =========== Driver: Installed Toolkit: Installed in /usr/local/cuda-11.2/ Samples: Installed in /root/, but missing recommended libraries Please make sure that - PATH includes /usr/local/cuda-11.2/bin - LD_LIBRARY_PATH includes /usr/local/cuda-11.2/lib64, or, add /usr/local/cuda-11.2/lib64 to /etc/ld.so.conf and run ldconfig as root To uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-11.2/bin To uninstall the NVIDIA Driver, run nvidia-uninstall Logfile is /var/log/cuda-installer.log

6. 执行nvidia-smi验证

补充

需注意，在卸载完驱动后，需要更新下initramfs，否则可能会在安装新的驱动重启后，执行nvidia-smi时遇到Failed to initialize NVML: Driver/library version mismatch错误。 如果已经安装完成并重启后遇到如上错误，可通过以下方法解决： rmmod nvidia_drm rmmod nvidia_modeset rmmod nvidia cd /boot mv initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak dracut -vf initramfs-$(uname -r).img $(uname -r)
