How to Use CentOS to update yum source in RHEL5

Today, I started my job on the first day. The new company's server uses RHEL. I personally don't like RHEL very much. I still don't have to work. Khan received a request to install several software packages, I used to use yum in CentOS, but it is not easy to use RHEL update packages. Although there are a lot of information on the Internet, I will do it myself after practice, the following is a summary of the practical results tonight: 1. Uninstall the yum package in the system [root @ localhost ~] # Rpm-qa | grepyumyum-3

Today, I started my job on the first day. The new company's server uses RHEL. I personally don't like RHEL, so I still have to work.

I received a request to install several software packages. I used to use yum in CentOS, but it is not easy to use RHEL update packages. Although there is a lot of information on the Internet, but what we will do after practice is our own. The following is a summary of our practical achievements tonight:

1. Uninstall the yum package in the system

[Root @ localhost ~] # Rpm-qa | grep yum

Yum-3.2.8-9.el5

Yum-rhn-plugin-0.5.3-6.el5

Yum-metadata-parser-1.1.2-2.el5

Yum-security-1.1.10-9.el5

Yum-updatesd-0.9-2.el5

[Root @ localhost ~] # Rpm-qa | grep release

RedHat-release-notes-5Server-12

Redhat-release-5Server-5.2.0.4

Run the rpm-e packges command to uninstall these software packages. If there is dependency, run the -- nodeps parameter.

Ii. Download the yum package in CentOS

# Cd/& mkdir yum & cd yum

Wget http://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/yum-3.2.22-33.el5.centos.noarch.rpm

Wget http://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/yum-updatesd-0.9-2.el5.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://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/centos-release-5-6.el5.centos.1.i386.rpm

Wget http://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/centos-release-notes-5.6-0.i386.rpm

Wget http://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm

Wget http://centos.ustc.edu.cn/centos/5/ OS /i386/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm

Then install these software packages. We recommend that you install these software packages together. If you encounter this problem and depend on your own software package, I use the -- nodeps parameter.

Example: rpm-ivh centos-release-5-6.el5.centos.1.i386.rpm -- nodeps

3. Finally, download the configuration file

Wget http://sudone.com/download/CentOS-Base.repo-O/etc/yum. repos. d/CentOS-Base.repo

Cd/etc/yum. repos. d/

Use the vim editor to edit the CentOS-Base.repo for replacement

: 1, $ s/$ releasever/5.5/g (Note: My system is 5.5, so here I change to 5.5)

4. import key

Rpm -- import http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5

Finally, test yum-y install httpd.

OK.
