CentOS 5上如何安装yum

Posted 2021-03-01 sha1234

使用过CentOS的用户们应该都知道，在CentOS上是自带yum的，自带yum为什么还要安装呢？其实在很多系统中都不一定安装了yum，因此我们就需要自己动手安装，那么你们知道CentOS 5上如何安装yum吗？

下面有两种办法可以安装yum：

一、下载yum的rpm包直接安装

http://centos.ustc.edu.cn/centos/5.4/os/i386/CentOS/yum-3.2.22-20.el5.centos.noarch.rpm

http://centos.ustc.edu.cn/centos/5.4/os/i386/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm

下载到某个目录之后，执行下面的命令
rpm -ivh yum*.rpm
如果提示缺少什么文件的话，请看第二种方法。

二、通过rpm包来安装
依次执行下面的命令：
rpm -Uvh http://mirror.centos.org/centos-5/5/os/i386/CentOS/elfutils-libs-0.137-3.el5.i386.rpm
rpm -Uvh http://mirror.centos.org/centos-5/5/os/i386/CentOS/gmp-4.1.4-10.el5.i386.rpm

rpm -Uvh http://mirror.centos.org/centos-5/5/os/i386/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm (2)
yum -y update

上文中就是我介绍CentOS 5上如何安装yum的方法，有些时候单纯的某一种方法并不能安装好yum，那就就需要两者结合起来，一切就OK了。
