在阿里云的GPU服务器上安装cuda没有什么问题，在自己的服务器上安装遇到一些问题，记录如下
注意
硬盘空间 需要root用户安装
参考
CentOS 7 设置默认进入图形界面或文本界面
Linux安装Nvidia显卡驱动：禁用The Nouveau kernel driver的方法！
查看显卡是否存在
[cndaqiang@mom ~]$ lspci | grep -i vga
05:00.0 VGA compatible controller: NVIDIA Corporation GM107 [GeForce GTX 750 Ti] (rev a2)
09:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. MGA G200e [Pilot] ServerEngines (SEP1) (rev 05)
禁用Nouveau驱动
Centos之前安装了Nouveau的驱动
- 把驱动加入黑名单中: 在
/etc/modprobe.d/blacklist.conf在后面加入：blacklist nouveau - 使用 dracut重新建立 initramfs p_w_picpath file :
#备份 the initramfs file $ sudo mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak #重新建立 the initramfs file $ sudo dracut -v /boot/initramfs-$(uname -r).img $(uname -r)
开机默认文本模式
[cndaqiang@mom ~]$ systemctl get-default
multi-user.target
[cndaqiang@mom ~]$ sudo systemctl set-default multi-user.target
重启，检查nouveau driver确保没有被加载！
$ lsmod | grep nouveau
一些依赖
yum install epel-release
yum install --enablerepo=epel dkms
安装
从CUDA Toolkit 10.1 Download下载cuda_10.1.105_418.39_linux.run
./cuda_10.1.105_418.39_linux.run
安装即可，安装结果
[root@mom cndaqiang]# ./cuda_10.1.105_418.39_linux.run
===========
= Summary =
===========
Driver: Installed
Toolkit: Installed in /usr/local/cuda-10.1/
Samples: Not Selected
Please make sure that
- PATH includes /usr/local/cuda-10.1/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-10.1/lib64, or, add /usr/local/cuda-10.1/lib64 to /etc/ld.so.conf and run ldconfig as root
最后把安装所说的添加PATH和LD_LIBRARY_PATH
编译vasp所需的cublas和cuda库，在安装cuda时自定义的安装目录的lib目录下，或者在 /usr/lib 里面，编译时，注意修改makefile.include
查看运行状况
