安装ntfs-3g支持

CentOS默认源里没有ntfs-3g，想要添加ntfs支持，无非是自己下载编译安装或者加源yum安装。

昨天重新安装了一个CentOS7，用的是添加aliyun的epel源来yum安装的方式，简单易行。

1、加源

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

2、安装

yum update;

sudo yum install ntfs-3g

引导文件更新

yum search ntfs

...

======= N/S matched: ntfs =======
findntfs.x86_64 : Find NTFS partitions
fuse-ntfs-3g.x86_64 : Linux NTFS userspace driver
fuse-ntfs-3g-devel.x86_64 : Header files, libraries and development documentation for fuse-ntfs-3g
ntfsprogs.x86_64 : NTFS filesystem libraries and utilities

We will install these, using yum install <package name>. Then, we can run the necessary GRUB2 update. And for the fun of it, examine the Windows 7 partition using the file manager. Yup, it works.
