挂载移动硬盘
一。众所周知，在安装完Centos完了以后，是没有编译环境的，我自己挂上光盘，手动安装解决了几十的依赖关系，在配置些软件时，还是经常报些依赖软件包的缺失，很是头疼，后来百度了下centos需要装的编译环境，在这里记录下（使用yum安装）
yum install gcc gcc-c++ gcc-g77 flex bison autoconf automake bzip2-devel zlib-devel ncurses-devel libjpeg-devel libpng-devel libtiff-devel freetype-devel pam-devel openssl-devel libxml2-devel gettext-devel pcre-devel，如果嫌麻烦的话，那就直接yum groupinstall "Development tools"
二。安装NTFS-3G依赖FUSE的支持，所以先解压安装FUSE。
安装FUSE命令：yum install fuse
1）下载ntfs-3g工具：http://www.tuxera.com/community/ntfs-3g-download/
下载完成 ntfs-3g_ntfsprogs-2014.2.15.tgz
2）解压缩 tar -zxvf ntfs-3g_ntfsprogs-2014.2.15.tgz
解压缩后进入文件夹ntfs-3g_ntfsprogs-2014.2.15
3）编译并安装
./configure
make
make install
4）查看USB设备点

/dev/sda1 1 38914 312569176 7 HPFS/NTFS
#fdisk -l （需要ROOT权限）
5）用root权限建立挂载点的文件目录
[root@Chen ntfs-3g_ntfsprogs-2016.2.22]# mkdir /mnt/win
6）执行挂载命令
命令：mount -t ntfs-3g /dev/sda /mnt/win 执行后出现如下：
NTFS signature is missing.
Failed to mount '/dev/sda': 无效的参数
The device '/dev/sda' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of apartition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
命令：# mount -t ntfs-3g /dev/sda1 /mnt/win 执行后出现如下：
The disk contains an unclean file system (0, 0).
The file system wasn't safely closed on Windows. Fixing.
[root@Chen ntfs-3g_ntfsprogs-2016.2.22]#
进入 /mnt/win，发现挂载成功，没有急，不过弄了一天了呵呵。
如果要开机自动挂载ntfs分区，需要更改/etc/fstab文件
用vi 打开fstab文件加入如下两行
/dev/sda3 /mnt/windows/d ntfs-3g defaults 0 0
/dev/sda4 /mnt/windows/e ntfs-3g defaults 0 0
