centos上如何yum安装git?

yum install git 出现错误:

[root@myhost test]# yum install git

Nothing to do

解决办法：

需要先添加EPEL(Extra Packages for Enterprise Linux) repository: CentOS5.x 32-bit(x86/i386):  rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm CentOS5.x 64-bit(x64):  rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm  CentOS6.x32-bit (x86/i386):  rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm CentOS6.x 64-bit(x64):  rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm

然后yum install git就能安装了。

 备注： 查看centos版本的方法：
