How do I use yum command to update and patch my Red hat Enterprise Linux / CentOS Linux version 5.x server via RHN / Internet? Can I use up2date command under RHEL 5?
up2date command was part of RHEL v4.x or older version. You need to use yum command to update and patch the system using RHN or Internet. Use yum command to install critical and non-critical security updates as well as binary packages. Login as the root user to install and update the system.
Task: Register my system with RHN
To register your system with RHN type the following command and just follow on screen instructions (CentOS user skip to next step):
# rhn_register
WARNING! These examples only works with RHEL / CentOS Linux version 5.x or above. For RHEL 4.x and older version use up2date command.Task: Display list of updated software (security fix)

You can use same command to list packages that satisfy dependencies:
# yum whatprovides {dependency-1} {dependency-2}
Refer yum command man page for more information:
# man yum

It is possible to configure yum to install rpms from local media, using the following method:
1. Create a new repository file: /etc/yum.repos.d/local.repo
2. Type the following:
[local]
name=Red Hat Local Repository
baseurl=file:///media/RHEL_5.3%20i386%20DVD/Server
enabled=1
gpgcheck=0
The baseurl should be web-encoded (ie space=%20) point to the local media which contains the rpms to install and any dependent rpms, and the folder repodata/ with repomd.xml and TRANS.TBL.
3. Finally, run (as root):
yum install [package]
thanks to hellp

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named sqlitecachec
Please install a package which provides this module, or
verify that the module is installed correctly.
It’s possible that the above module doesn’t match the
current version of Python, which is:
2.4.3 (#1, Jan 14 2008, 18:32:40)
[GCC 4.1.2 20070626 (Red Hat 4.1.2-14)]
If you cannot solve this problem yourself, please go to
the yum faq at:
http://wiki.linux.duke.edu/YumFaq
This is wonderful way to learn possible problems.
great……………….

Hi all,
I have a problem with installation of an software. I have installed on my laptop CentOS5.4 with all repositories activate (I think) and yum upgrade and update. I working in engineering domain, so I am curious how works ANSYS 11 on Linux 64 biti (at my work I use ANSYS on windows).
I installed first on Ubuntu9.10 (unfortunately not all modules works fine) and installation it was ok, and I tested and everything works done. After that I try to install it on CentOS because this software is made to works done only on Rhel platform (.rpm). So, I encountered the next message, which I don’t understand what means and why appear:
>su
>password
>./INSTALL
>bash: ./INSTALL: /bin/sh: bad interpreter: Permission denied
after that I try:
>su
>password
>rpm -i INSTALL
after that I try:
>su
>password
>sudo ./INSTALL
sudo: unable to execute ./INSTALL: Success
I waiting yours answer or opinion reffering to my problem, because I’m very curious.
Best regards
I think you’ll find that the INSTALL file is a text file that gives you instructions on how to compile, then install the program from source.
This install method typically involves:
>./configure
>./make
>./make install
If you have the rpm available, use the “ls” command to search the relavant directory and find the *.rpm file. That’s what you’ll want to run the “rpm -i” command with.
As far as the INSTALL file: instead of trying to execute it, use your favorite editor to view it, or use the cat command:
> cat ./INSTALL |less
Just to add a side note, you don’t use “./” with make and make install, you should only use it with configure, so it would be
# ./configure# make
# make install
It’s not a bad idea to run the command:
# yum check-updates
This will let you know which packages are due to be updated without actually running the update. Saves a bit of bother if there is a major upgrade about to happen.
So, how do you update an installed yet outdated rpm, when YUM doesn’t find any updates for it?
Why can’t RedHat make YUM work right? and why can’t they call it something a little more descriptive? Linux is crap! Program names don’t even describe what a program does! How can anything be more non-userfriendly!
Have you tried out yum info command?

Hello! I need to install a specific version of packages, for example, if the last version of “seamonkey” is “seamonkey-1.0.9-0.57.el3.i386.rpm” I need to install seamonkey-1.0.9-0.45.el3.i386.rpm, is that possible? obviously I know which is the number of the previous version.
Excuse me for my english.
Thanks so much

Hi,
I am using CentOS5.5 and I want to install few packages through yum.
like gnome-libs,XFree-libs etc. But when I run “yum install gnome-libs” it gives no
package available.
Can you suggest me how to update yum to make these package available?
Thanks…
yum is crap, it was modelled after aptitude which is the debian packages manager, apt is way better than yum, and debian is a kickass to redhat.
nice feature
Hi,
100 Linux servers which are part of production, doesn’t have access to internet. It’s in private DMZ. YUM will not work here. How would you install the latest patches?
@Sam
Have a look at RHN Proxy Server,
http://www.redhat.com/red_hat_network/faq/
It allows you to cache rpms internally and distribute them to your local network.
@suchi
the guide suggests doing this:
yum whatprovides gnome-libs
-1
@Feck McConnel
You can try issuing 3rd party repositories on RH/CentOS such as EPEL, RPMFusion are two good choices, these might have more recent version of your software but remember that RH/CentOS are more geared for stability rather than bleeding edge. In that case you can try Fedora.
