1.更改源

安装rpmforge源

rpm -i http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

2.如果报错

warning: rpmts_HdrFromFdno: Header V3 DSA/SHA1 Signature, key ID e8562897: NOKEY
# rpm --import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-6

3.安装证书

# rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

4.更新rpmforge-extra源

# yum --enablerepo=rpmforge-extras update

5.安装Git

插槽可用的git模块

# yum --enablerepo=rpmforge-extras provides git

6.安装git-1.7.11

# yum --enablerepo=rpmforge-extras install git-1.7.11.3-1.el6.rfx.x86_64

7.原来的1.7.1版本的git会被覆盖

# git --version
