之前都是在Centos6下进行CUDA开发，安装和配置CUDA环境请參考另外一篇博客（Linux（redhat）CUDA安装）。由于Centos7有较大变动，所以安装CUDA过程中遇到了一些麻烦。原因初步归结于OpenGL的安装。以下具体介绍安装配置过程

关闭防火墙和selinux和补充包和建立本地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 
又一次启动继续配置

# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.
mount -o loop /cudainstall/CentOS\ 7\ x86_64.iso /mnt/iso/
touch /var/lock/subsys/local

[root@localhost yum.repos.d]# hostnamectl set-hostname cuda02
[root@cuda02 ~]# yum install kernel-devel gcc gcc-c++ yum install libX*

检查nouveau
[root@cuda01 ~]# lsmod |grep nouveau

假设有输出 使用modprobe -r nouveau
[root@cuda01 ~]#init 3

安装cuda时一定不要安装OpenGL；切记，否则有可能安装完之后。图形化桌面启动不了，过程中会出现例如以下错误信息
[root@cuda02 cudainstall]# chmod +x cuda_7.0.28_linux.run
[root@cuda02 cudainstall]# ./cuda_7.0.28_linux.run
