Red Hat Package Management

Red Hat / CentOS RPM and YUM package management.

This tutorial covers installing, updating, removing and managing application packages for Linux distributions using the Red Hat Package Management (RPM) and the Yellowdog Updater, Modified (YUM) commands. Distributions using this system include Red Hat Enterprise Linux, older releases of Fedora, CentOS and Suse.

RPM - Redhat Package Manager:

The rpm command is used to manage software applications and system modules for Red Hat, Fedora, CentOS, Suse and many other Linux distributions.

Step One: Import Red Hat and Fedora GPG signature keys:

View your public key: (RHEL5)

[root@yoserver2 ~]# rpm -qa gpg-pubkey
gpg-pubkey-ed555983-3457f7f3
[root@yoserver2 ~]# rpm -qi gpg-pubkey-ed555983-3457f7f3
...
...
      
(Thus already installed. Your system is ready.)

Remove your public key: (RHEL5)

[root@yoserver2 ~]# rpm -e gpg-pubkey-ed555983-3457f7f3
      

Install public key: (Red Hat package up2date - now depricated. Use YUM.)

[root@yoserver2 ~]# rpm --import /usr/share/rhn/RPM-GPG-KEY
[root@yoserver2 ~]# rpm --import /usr/share/rhn/RPM-GPG-KEY-fedora
          
Do this once to configure RPM so that you won't constantly get the warning message that the signature is "NOKEY".
The purpose is to protect you from using a corrupt or hacked RPM.
Once these command are performed, you are ready to use the RPM command. (This is also required for the YUM commands below.)

Note: Many GPG public keys for other RPM packages (i.e. MySQL: 0x5072E1F5), can be obtained from http://www.keyserver.net/.
(The following RPM installation warning will inform you of the key to obtain: warning: MySQL-XXXX.rpm: V3 DSA signature: NOKEY, key ID 5072e1f5)
Importing a new key from key server:

  1. gpg --keyserver keyserver.veridis.com --recv-key 5072e1f5
  2. gpg --export -a 5072e1f5 > pubkey_mysql.asc
  3. rpm --import pubkey_mysql.asc

Step Two: RPM commands and their use

RPM Command Description
rpm -qilp program_package-ver.rpm Query for information on package and list destination of files to be installed by the package.
You can also use the Gnome GUI program file-roller to view and read the contents of an RPM. Great tool for inspecting an RPM package and reading the package documentation before you decide to install the package.
rpm2cpio - < program_package-ver.rpm | cpio -id ./path/and/file-name Extract a single file (with path) from the RPM package to the local directory.
rpm -Uvh program_package-ver.rpm Upgrade the system with the RPM package
rpm -ivh program_package-ver.rpm New Install
rpm -Fvh program_package-ver.rpm Freshen install. Removes all files (including config files) of older version during upgrade.
rpm -q program_package Query system RPM database (/var/lib/rpm), to see if package is installed.
rpm -qi program_package Query system RPM database for info/description on package (if installed)
rpm -ql program_package List all files on the system associated with the package.
rpm -qf file Identify the package to which this file belongs.
rpm -e program_package Uninstall package from your system
rpm -qa List ALL packages on your system. Use this with grep to find families of packages.
rpm -qp --requires program_package-ver.rpm List dependancies (files and packages) of RPM. List prerequisites.
rpm -q --whatrequires program_package List dependant packages of RPM. What packages will break if this RPM is removed.
rpm -K --nogpg *.rpm Non sure if RPM downloaded ok? Verify md5 sum.

RPM Flag Description
--nodeps RPM flag to force install even if dependency requirements are not met.
--force Overwrite of other packages allowed.
--notriggers Don't execute scripts which are triggered by the installation of this package.
--root /directory-name Use the system chrooted at /directory-name. This means the database will be read or modified under /directory-name. (Used by developers to maintain multiple environments)
--ignorearch Allow installation even if the architectures of the binary RPM and host don't match. This is often required for RPM's which were assembled incorrectly

Notes:

  • Fedora RPM downloads: http://archives.fedoraproject.org/pub/archive/fedora/linux/releases/##/Fedora/arch/os/Packages/
    Use your browser, wget, curl (downloads using http, https, ftp, ...) or ftp the site download.fedora.redhat.com (login: anonymous, password: your-email-address).

  • Many times, (like with glibc library or Netscape RPMs etc) it is necessary to mention two or more packages on the command line. The rpm command will account for the co-dependency of the packages. i.e.:
    rpm -ivh abc-package1-i386.rpm abc-package2-i386.rpm abc-package3-i386.rpm

  • Configuration information is stored in /var/lib/rpm

  • Database of descriptive package info. RPM package rpmdb-redhat. Installs database of all packages in distributions to make RPM more informative.

  • When installing additional RPM's from the Red Hat CD, cd to the RPMS directory on the CD which contains the packages to be installed.

  • Building from a "src" (source) RPM: rpmbuild --rebuild package-name.src.rpm
    The source will be placed in /usr/src/redhat/RPMS/....
    The command then performs a prep, compile, install and finally creates a new binary RPM package. Use option --clean for cleanup.
    The command rpmbuild --showrc package-name.src.rpm shows options to be used as specified in rpmrc and macros configuration file(s).
    The source RPMs are not in the RPM database and will not be seen with "rpm -qa

  • [Potential Pitfall]: If you get the errors:
    error: cannot get exclusive lock on /var/lib/rpm/Packages
    error: cannot open Packages index using db3 - Operation not permitted (1)
    error: cannot open Packages database in /var/lib/rpm
    then you must check:
    • Who are you logged in as?: whoami
      You must be root.
    • File permissions: ls -l /var/lib/rpm/Packages
      File must be owned by root.
    • Command to kill processes locking file: fuser -k /var/lib/rpm/Packages
      It is best to terminate processes by exiting program (like glint) normally if possible.

  • [Potential Pitfall]: If you get the errors:
    [root]# rpm -e package-name
    error: "package-name-X.X.X-X" specifies multiple packages
    This is because a package is doubly listed: (Often due to dual 32/64 bit architectures such as the AMD Athelon/Opteron and Intel EM64T - Extended Memory 64 Technology)
    [root]# rpm -q package-name
    package-name-X.X.X-X
    package-name-X.X.X-X
    Fix: rpm -e --allmatches package-name

  • [Potential Pitfall]: You try and install an RPM but you can not get the appropriate version of the run time libraries because they are too old and not present on your system or you get a runtime error:
    /usr/bin/ld: cannot find /lib/libxx.so.1.0.4

    Here is how to install some old libraries on your newer system without corrupting your current installation.

    1. First force the installation of the RPM without the dependency requirement: rpm --nodeps -ivh xxxx-...rmp.
    2. Next download an old RPM of the appropriate library, i.e. glibc-x.x.x.rpm
    3. Extract the libraries from the RPM: rpm2cpio glibc-x.x.x.rpm | cpio -idv
      This will install to your current directory: ./usr/lib/.. and ./lib/...
    4. Manually copy the library file to the library directory or path accessible by LD_LIBRARY_PATH or ldconfig: i.e.
      cp ./lib/libxx.so.1.0.4 /lib/libxx.so.1.0.4

Automated System Updates: up2date (Red Hat 7.1 and later)

Select the red dot and exclamation mark icon on the toolbar to launch up2date and follow the GUI. One may also use the command line if managing a remote server.

Red Hat up2date tool bar icon

Execute the following commands (in order given) to perform an automatic system update:

  1. /usr/bin/rhn_register :You must first register your system with the Red Hat database. This command will perform a hardware inventory and reporting of your system so that Red Hat knows which software to load to match your needs.
  2. /usr/bin/up2date-config :This allows you to configure the "up2date" process. It allows you to define directories to use, actions to take (i.e. download updates, install or not install, keep RPM's after install or not), network access (i.e. proxy configuration), use of GPG for package verification, packages or files to skip, etc. Use of GPG requires the Red Hat public key: rpm -import /usr/share/rhn/RPM-GPG-KEY
  3. /usr/sbin/up2date :This command will perform an audit of RPM's on your system and discover what needs to be updated. It gives you a chance to unselect packages targeted for upgrade. It will download RPM packages needed, resolve dependencies and perform a system update if requested.

[Potential Pitfall]: This works quite well but it is not perfect. Red Hat 7.1 Apache upgrade to 1.3.22 changed the configuration completely. (Beware. manual clean-up and re-configuration is required). When up2date finds the first messed up dependency it stops to tells you. You then have to unselect the package. It then starts again from the beginning.

Installing a new package with up2date: up2date package-name
The package name is given without the version number. If the package is not currently installed, it will be downloaded and installed, along with any dependencies that package requires.

Command line options (partial list) for up2date:

Option Description
--nox Do not display the GUI interface.
-u
--update
Completely update the system
-h
--help
Display command line arguments
-v
--verbose
Print more info about what up2date is doing
--showall Show a list of all packages available for your release of Red Hat Linux, including those not currently installed.

Also see man pages for:

  • up2date-gnome
  • rhn_register-gnome

Notes:

  • Update in console mode (no GUI): up2date --nox --update
  • Configuration file for up2date: /etc/sysconfig/rhn/up2date
  • System id and configuration info held in XML format for up2date: /etc/sysconfig/rhn/systemid
  • The default download directory for up2date is /var/spool/up2date/. RPM packages and support files are downloaded to this directory.
  • An automated alert to the need to update utilizes the rhnsd which can be started by issuing the command: /etc/rc.d/init.d/rhnsd start

YUM/YUMEX: RPM Updates

YUM (Yellowdog Updater, Modified) is a client command line application for updating an RPM based system from an internet repository (YUM "yum-arch" server) accessible by URL (http://xxx, ftp://yyy or even file://zzz local or NFS). The YUM repository has a directory of the headers with RPM info and directory path information. YUM will resolve RPM package dependencies and manage the importation and installation of dependencies.

YUM is also capable of upgrading across releases. One can upgrade Red Hat Linux 7 and 8 to 9. Red Hat 8 and 9 can be upgraded to Fedora Core. See Fedora YUM release upgrades or upgrade Redhat 6 to 7. Note that RHEL6 is the first release of the enterprise product which can be upgraded to the next release.

Yum Configuration:

YUM config file: /etc/yum.conf (CentOS 5)

You may list packages you wish NOT to update (Space delimited list. '*' wildcards allowed.): exclude=package-name
(i.e. On x86_64 I do not update firefox or mozplugger with the 64 bit version, I use the 32 bit version so that 32 bit plugins will work.)
Set "gpgcheck=0" to avoid the signature check.
For the option "gpgcheck=1" to work, use the "rpm --import GPG-KEY commands as detailed above in section one of the RPM tutorial.

  • Fedora examples (more repositories: Jpackage, ...)


Registering Red Hat Enterprise Linux to enable YUM repository use:

Commands:
  • rhn_register: GUI to enter user account and "Installation Number". Must purchase a license to get this.
  • rhnreg_ks: Register a login/user account
Data is stored in /etc/sysconfig/rhn/

Yum Examples And Use:

Using YUM and YUM examples:

  • Update:
    • List packages which will be updated: yum check-update
      (Does not perform an update)
    • Update all packages on your system: yum update
    • Update a package: yum update package-name
    • Update all with same prefix: yum update package-name-prefix\*
      This command will update your system. It will interactively ask permission. i.e. "Is this ok [y/N]:"
    • To avoid the prompt/questions use the command: yum -y update Sample session:
      # yum -y update

      [Potential Pitfall]: Many times I have found that I can get the following errors:

      Setting up Update Process
      Setting up repositories
      Reading repository metadata in from local files
      Could not find update match for package-name ... ... --> Finished Dependency Resolution Error: Missing Dependency: package-name
      I find that the error is traced to having two version of a package installed at once. The following command will reveal if this is true: rpm -q package-name. If there are two versions of the same package installed, I find that removing the newer version and re-running YUM to install an upgrade gets past these errors.
  • To install a single package: yum -y install package-name
    This will also resolve package dependencies.
  • Remove a package: yum remove package-name
  • Info:
    • List available packages, version and state (base, installed, updates-released): yum list
    • List the packages installed which are not available in repository listed in config file: yum list extras
    • List packages which are obsoleted by packages in yum repository: yum list obsoletes
  • Clean local cache of headers and RPM's: yum clean all
    (See: /var/cache/yum/)

Yum Commands:

YUM Command Description
yum -y install package-name Install package.
yum -y install package-name.arch Install package of specified architecture. This is common when installing Firefox "i386" on a "x86_64" platform.

Notes:

  • yum man page
  • yum.conf man page
  • You can set up your own YUM server for your own cluster or intranet. Set up a web server with the same paths as used in the configuration files and point your configuration files to your server. See YoLinux web server tutorial for configuration information.
  • Fedora configures YUM as a daily cron job: /etc/cron.daily/yum.cron
    #!/bin/sh

    if [ -f /var/lock/subsys/yum ]; then
    /usr/bin/yum -R 10 -e 0 -d 0 -y update yum
    /usr/bin/yum -R 120 -e 0 -d 0 -y update

I have the Red Hat 6 version and I have found it to be very helpful. I have found it to be way more complete than the other Linux books. It is the most complete general Linux book in publication. While other books in the "Unleashed" series have disappointed me, this book is the best out there.
