1. I want to install EPEL repository

For the impatient

I am using CentOS 6

•  
  • Go to http://ftp.riken.jp/Linux/fedora/epel/6/i386/repoview/epel-release.html
  • Download RPM and install the package (yum install /path/to/rpm) from su

For the rest

Go to  http://wiki.centos.org/AdditionalResources/Repositories it contains the additional repositories.

Find your favourite repository/EPEL and follow the links, they should have updated information over time.

2. How to mount 'ntfs' partition in CentOS?

Read the guide here - http://wiki.centos.org/TipsAndTricks/NTFS

3. How do I create CentOS local repository?

For the impatient
I am using CentOS 6

• yum install createrepo
• createrepo /path/to/rpms

 

4. Create local yum repository

For the impatient

I am using CentOS 6

• Should have createrepo package. If not then yum install createrepo
• Create a repository directory that will contain rpms (mkdir /media/repo)
• #createrepo /path/to/rpms (here /media/repo)
• #nano /etc/yum.repos.d/local.repo
• Contents of local.repo

[local]

Name=CentOS 6.3 $releasever $basearch local repository

baseurl=file:///media/repo

enabled=1

Follow the guide here - http://adhocshare.blogspot.in/2012/08/create-your-own-local-yum-repositories.html

For setting up local repository go to section 4.

8. Install VirtualBox on CentOS
