主机配置：
CPU：E3 1230 V5+
GPU：EVGA GTX1080 8G SC ACX 3.0
内存：DDR4 2133 8G 两根
主板：技嘉X150M-PRO-ECC
选择Ubuntu 16 LTS，因为它是一个长期支持版本，而且我的硬件比较新，可能驱动方面在支持和兼容性上面可能会更好
另外选择这块主板一个原因是M.2的SSD接口，结果兼容性问题很严重，网上很多都在吐槽二次启动问题，没想到中标了，最后放弃了M.2，老老实实用SATA3.0。
概览
- 安装Ubuntu 16.0.4
- 配置系统编译环境
- 编译安装TensorFlow
安装Ubuntu 16.0.4
由于本人是两块硬盘，准备安装双系统。先在第一块硬盘装好win10，然后把下载好的Ubuntu ISO 文件烧写到U盘，修改系统BIOS，把U盘启动顺序设置到第一然后重启，重启完成后根据安装提示一步一步往下走就行，在选择系统语言的步骤最好选择英文，少折腾。
可能会遇到的问题：
- 安装完成重启后黑屏
- 安装完成后登录无法进入桌面
安装完成重启后黑屏
由于我是双系统，在开机后显示引导菜单时候按e按钮进入编辑grub，找到quiet splash，修改为 quiet splash nomodeset，就是在末尾添加nomodeset，然后按F10键引导。如果进入到登录界面，按住ctrl+alt+f1，进入命令行登录，输入用户名密码后，编辑sudo vi /etc/default/grub 文件，找到如下行:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
修改为：
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
保存后，重启
sudo reboot
安装ubuntu16.0.4后无法进入桌面
不要急，按住ctrl+alt+f1，进入命令行登录，然后第一件事，更新source，大局域网，你懂的：）
sudo vi /etc/apt/sources.list
如果你不习惯，或者是linux小白，可以用nano编辑器来修改：
sudo nano /etc/apt/sources.list
添加mirrors.163.com的源，ubuntu 16的代号 xenial
deb http://mirrors.163.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ xenial-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ xenial-backports main restricted universe multiverse
我个人感觉电信宽带用163的镜像源会更快一点，如果是教育网，可以用中科大的源。
修改完成后保存，apt update，然后upgrade
sudo apt-get update
sudo apt-get upgrade
然后升级内核（安装好后是4.4，建议升级到4.6.7），此步骤可以跳过
先看看内核版本：
uname -r
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.7/linux-headers-4.6.7-040607_4.6.7-040607.201608160432_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.7/linux-headers-4.6.7-040607-generic_4.6.7-040607.201608160432_amd64.deb
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.7/linux-image-4.6.7-040607-generic_4.6.7-040607.201608160432_amd64.deb
sudo dpkg -i linux-*.deb sudo update-grub
sudo reboot now
重启完成后开始安装显卡驱动了。（我这个地方是gtx1080的显卡，选择nvidia-367驱动）
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-367
sudo apt-get install mesa-common-dev
sudo apt-get install freeglut3-dev
sudo reboot
完成后重启，应该能进入桌面了，电脑分辨率也正常了。（我的带鱼屏2560X1080）
配置系统编译环境
下载安装CUDA 8.0.44（Nvidia下载 或者 百度网盘下载）
sudo sh cuda_8.0.44_linux.run
开始安装后会不断询问安装内容，请一定要注意
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 367.**?
(y)es/(n)o/(q)uit: n
这个步骤一定要选择no，否者前面最新的显卡驱动就白装了（如果实在不小心踩了这个坑，没关系，把前面步骤的显卡驱动重新装一次，安装前先卸载）
完成后注意看提示，如果有问题可以参考这篇blog（我没遇到）
配置环境变量：
nano ~/.bashrc
export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
如果在桌面的Terminal配置环境变量，完成后exit下，再进入让环境变量生效，如果在系统命令行模式，可以手动执行以下上面的export两行命令。
完成后开始安装Cudnn 5.1，官方下载地址 或者 百度网盘地址
下载完成后，解压复制到目录（如果CUDA8.0是默认安装路径，这个地方就不用修改路径了）
tar xvf cudnn-8.0-linux-x64-v5.1.tgz
sudo cp cuda/include/cudnn.h /usr/local/cuda/include
sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
好了，现在输入命令看看是否正常显示显卡信息：
nvidia-smi
然后进入刚刚CUDA安装的sample目录，默认是~/下，然后make，编译完成后输入
./NVIDIA_CUDA-8.0_Samples/bin/x86_64/linux/release/deviceQuery
应该会正常显示详细设备信息：
