yum command: Update / Install Packages Under Redhat Enterprise / CentOS Linux Version 5.x

by on February 29, 2008 · 72 comments· LAST UPDATED December 5, 2009

in , ,

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)

Type the following command at shell prompt:
# yum list updates

Task: Patch up system by applying all updates

To download and install all updates type the following command:
# yum update

Task: List all installed packages

List all installed packages, enter:
# rpm -qa
# yum list installed

Find out if httpd package installed or not, enter:
# rpm -qa | grep httpd*
# yum list installed httpd

Task: Check for and update specified packages

# yum update {package-name-1}
To check for and update httpd package, enter:
# yum update httpd

Task: Search for packages by name

Search httpd and all matching perl packages, enter:
# yum list {package-name}
# yum list {regex}
# yum list httpd
# yum list perl*

hi puskhar kumar,
if you want to install linux or fedora or centos first of all you set a bois setup to first set a cdrom to select for booting process then restart your system and then press f9 then automatically to process for a next version installation.

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:

name=Red Hat Local Repository

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]

i have this error when instaling yum

# yum update
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

Thank you for this post. I didn’t know about the ‘groupremove’ function of YUM. That’s going to save HOURS of time later!

What is the command to add a YUM service on RHEL agent?



31 adminCAE April 10, 2010 at 4:53 pm

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:

>bash: ./INSTALL: /bin/sh: bad interpreter: Permission denied

after that I try:

>rpm -i INSTALL

after that I try:

>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


32 Leonardo April 28, 2010 at 7:25 pm

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:
>./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


33 xtatuto May 8, 2010 at 2:27 pm

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


34 peter June 17, 2010 at 11:54 pm

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.


35 Feck McConnell June 23, 2010 at 7:12 pm

So, how do you update an installed yet outdated rpm, when YUM doesn’t find any updates for it?


36 dtolj April 13, 2011 at 9:58 pm

@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.


37 Rex July 23, 2010 at 8:42 pm

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!


38 nixCraft July 23, 2010 at 9:05 pm

Have you tried out yum info command?

yum info packageName
yum info httpd
yum list
yum list httpd
yum list | less

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

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?



42 dtolj April 13, 2011 at 9:55 pm

the guide suggests doing this:
yum whatprovides gnome-libs


43 HFalahati June 11, 2011 at 6:42 am

I use this command to install screen on centos
” yum whatprovides screen”
but it shows this error :
” Warning: 3.0.x versions of yum would erroneously match against filenames.
You can use “*/screen” and/or “*bin/screen” to get that behaviour
No Matches found”
I use ” yum whatprovides */screen ”
” ncurses-5.5-24.20060715.i386 : A terminal handling library
Repo : Rocks-5.4
Matched from:
Filename : /usr/share/terminfo/s/screen”

and something like this, but when I type “screen”, it says :
“-bash: screen: command not found”

I use this command too “yum whatprovides */bin/screen ”
“Rocks-5.4/filelists | 1.4 MB 00:00
No Matches found”

Please help me.
Thanks in advance.


44 HFalahati June 11, 2011 at 7:30 am

I solve my problem:)
you can download this rpm from this site

and then install it by this command:
yum install screen


45 meitham September 28, 2010 at 10:12 am

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.

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?


49 dtolj April 13, 2011 at 9:53 pm

Have a look at RHN Proxy Server,
It allows you to cache rpms internally and distribute them to your local network.

56 Dan March 6, 2015 at 5:56 pm

I don’t see any errors, I only see warnings with explanations afterwards of what is happening instead of the default.
(e.g. the user ‘mockbuild’ not existing, so it’s using root)
Your (source) RPM has been installed. You might want to install the binary RPM, however. The source RPM is only going to contain the source code, which isn’t going to help you unless you’re compiling it for some custom use.
