How to install centos 5 yum in rhel5

For those who often use centos, the yum that comes with it is very useful. Can their fellow brother rhel5 also install yum? I found a piece of information on the Internet and found that this is completely achievable. Let's take a look at his implementation method:
Uninstall the yum package of yum in RHEL first.
Query the previously installed Yum package:
Rpm-Qa | grep yum
Delete the yum package one by one according to the query above. Some of the packages are dependent here, So add -- nodeps to delete them, for example:
Rpm-e -- nodeps yum-3.0.5-1.el5

And so on.

### 1. Create the yum installation package directory and enter the directory:
Mkdir/tmp/Yum-packages
CD/tmp/Yum-packages

### II. Download all RPM packages required by Yum:
Wget http://mirror.centos.org/centos-5/5/ OS /i386/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
Wget http://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
Wget http://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
Wget http://mirror.centos.org/centos-5/5/ OS /i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

### 3. Install the python environment first:
Rpm-IVH python-iniparse-0.2.3-4.el5.noarch.rpm

### 4. Install all Yum packages:
Rpm-IVH yum-3.2.22-39.el5.centos.noarch.rpm yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm

### 5. Download the configuration file
Wget http://sudone.com/download/CentOS-Base.repo-O/etc/yum. Repos. d/CentOS-Base.repo
(Here we will explain that it is only in/etc/yum. repos. d/folder with the suffix. the repo file can be a newly added Yum source file in the yum source format, so you can place the yum source file you have found here, with the yum

It is quite easy to install and update the software from the source. You can add the yum source file to obtain the. Repo file written by people on the Internet in the following way: wget http://centos.ustc.edu.cn/centos-base.repo.5.

### 6. Now you can experience yum

Yum update
