EntOS default source without ntfs3g, want to add NTFS support, simply download the yum install compile and install or source.
Reinstall the CentOS7 yesterday, using the Add aliyun EPEL source to yum install, simple and easy.
1, add source
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum update;yum install ntfs3g
Source: http: //mirrors.aliyun.com/help/epel, explained there is no written source CentOS7 is actually there, into the inside of the 5/6 7 on the list.
