install git : linux(centOS)

I can't install "git" by using yum on CentOS.
Because the package "git" is not in yum "default" repository.

1. add 2 file

/etc/yum.repos.d/git.repo

-----
[git]
name=Base git repository
baseurl=http://www.kernel.org/pub/software/scm/git/RPMS/$basearch
enabled=1
gpgcheck=0

----

/etc/yum.repos.d/rpmforge.repo
----

[rpmforge]
name = Red Hat Enterprise $releasever - RPMforge.net - dag
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
enabled = 0
gpgcheck = 0

----


2. if checksum error is occurred,
#yum update
