目錄(?)[+]

基本環(huán)境

• cuda_7.0.28_linux.run
• CentOS 6.5

安裝過程

• 禁用Nouveau，這個驅(qū)動和Nvidia的驅(qū)動有沖突，需要先禁用掉，不然會不讓安裝，具體可參考NVIDIA CUDA GETTING STARTED GUIDE FOR LINUX
  
• 創(chuàng)建文件，/etc/modprobe.d/blacklist-nouveau.conf，其內(nèi)容如下：
  blacklist nouveau
  options nouveau modeset=0
• 重新生成kernel initramfs，即Regenerate the kernel initramfs，執(zhí)行如下命令
  sudo dracut –force
  注意：force前面是2個-
• 設(shè)置系統(tǒng)啟動為Text Mode，即修改文件：/etc/inittab，將id:5改為id:3，讓系統(tǒng)不從界面化啟動，安裝完成后，再修改過來。注意，不要從界面啟動，然后通過按ctrl+alt+f3進入Text界面來進行安裝，這個好像會出問題，會不讓安裝。
• 重啟系統(tǒng)
• 直接運行cuda_7.0.28_linux.run，該文件需要有可執(zhí)行權(quán)限
• 如果安裝時，提示X server is running，不讓進行安裝，則執(zhí)行如下操作：
  
• 查詢下和X相關(guān)的服務(wù)，pstree -p | grep X
• 如果查詢知道有服務(wù)在運行，就kill掉，比如：
  |-Xvnc(2259)
  |-Xvnc(2299)
  這時候，就依次執(zhí)行
  sudo kill -9 2259
  sudo kill -9 2299
  將相關(guān)服務(wù)給殺掉，這時候應(yīng)該就可以安裝了
• 運行安裝文件后，根據(jù)提示進行默認安裝即可。安裝完成后需要配置PATH和LD_LIBRARY_PATH。
• 將id:3修改回為id:5，重啟系統(tǒng)。
• 如果重啟后停留在進度條界面，正常進不了界面化的登錄界面，則按ctrl+alt+f3進入Text界面，登錄進入系統(tǒng)。然后查看/etc/X11/xorg.conf文件是否存在。一般是因為這個文件不存在導(dǎo)致的。這時候執(zhí)行如下命令：
  nvidia-xconfig
  該命令會生成相應(yīng)的xorg.conf文件

其他命令

• 在系統(tǒng)啟動時，即進度條狀態(tài)時，按下Esc鍵，會轉(zhuǎn)換到類似CMD命令似的界面，會顯示相關(guān)的啟動日志，可以查看相關(guān)東西。
• 也可以通過查看/var/log/文件夾下的Xorg.*類文件來查看啟動日志，比如
  ls /var/log/Xorg.*
  會顯示相關(guān)的文件：
  /var/log/Xorg.0.log
  /var/log/Xorg.1.log
  /var/log/Xorg.2.log
  一般Xorg.0.log是最新的日志文件，可以通過時間知道。

之前都是在Centos6下進行CUDA開發(fā)，安裝和配置CUDA環(huán)境請參考另外一篇博客（Linux（redhat）CUDA安裝）。因為Centos7有較大變動，所以安裝CUDA過程中遇到了一些麻煩，原因初步歸結(jié)于OpenGL的安裝。下面詳細介紹安裝配置過程

關(guān)閉防火墻和selinux和補充包和建立本地yum源

[root@localhost ~]# systemctl stop firewalld.service?
[root@localhost ~]# systemctl disable firewalld.service?
rm '/etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service'
rm '/etc/systemd/system/basic.target.wants/firewalld.service'
[root@localhost ~]# vi /etc/selinux/config?
[root@localhost ~]# cat /etc/selinux/config?


# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# ? ? enforcing - SELinux security policy is enforced.
# ? ? permissive - SELinux prints warnings instead of enforcing.
# ? ? disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# ? ? targeted - Targeted processes are protected,
# ? ? minimum - Modification of targeted policy. Only selected processes are protected.?
# ? ? mls - Multi Level Security protection.
SELINUXTYPE=targeted?

#
# In contrast to previous versions due to parallel execution during boot

# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure

如果有輸出 使用modprobe -r nouveau
[root@cuda01 ~]#init 3
