When using yum for package management in redhat, I encountered the following error:

[root@localhost Server]# yum install sudo
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
Setting up Install Process
No package sudo available.
Nothing to do

Solution:

1. uninstall the redhat yum package

[root@localhost Server]# rpm -qa | grep yum
yum-updatesd-0.9-2.el5
yum-security-1.1.16-13.el5
yum-metadata-parser-1.1.2-3.el5
yum-3.2.22-20.el5
yum-rhn-plugin-0.5.4-13.el5

[root@localhost Server]# rpm -e –nodepsyum-updatesd-0.9-2.el5yum-security-1.1.16-13.el5yum-metadata-parser-1.1.2-3.el5yum-3.2.22-20.el5yum-rhn-plugin-0.5.4-13.el5

2. switch to the directory where you want to save the yum package

[root@localhost Server]#cd /software/share

3. Download the yum package for centos

[root@localhost share]# wget http://centos.ustc.edu.cn/centos/5/os/i386/CentOS/yum-3.2.22-40.el5.centos.noarch.rpm

[root@localhost share]# wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo

6. Move the repo to the appropriate directory

[root@localhost share]# mv CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo

7. Make a cache

8. At this point, you can use yum for install operations normally
