LAB #1 - The rpm Command

In order to facilitate the installation, uninstallation and management of software (called packages), RHEL 9 uses a specific installable software file format. This is called RPM for Red Hat Package Manager. The command used to manipulate these packages is also called rpm.

The rpm command switches are:

[root@redhat9 ~]# rpm --help
Usage: rpm [OPTION...]

1.1 - Configuration

The main configuration file for the rpm command is /usr/lib/rpm/rpmrc:

[root@redhat9 ~]# more /usr/lib/rpm/rpmrc
#/*! \page config_rpmrc Default configuration: /usr/lib/rpm/rpmrc
# \verbatim
#
# This is a global RPM configuration file. All changes made here will
# be lost when the rpm package is upgraded. Any per-system configuration
# should be added to /etc/rpmrc, while per-user configuration should
# be added to ~/.rpmrc.

[q]

These directives indicate how to optimise the build of an rpm according to the processor type returned by the uname -p command. For example, the buildarchtranslate: athlon: i386 directive indicates that the process should use i386 optimisations when building a src.rpm on a athlon architecture.

If, on the other hand, you want the athlon optimisations to be used, you should include the buildarchtranslate: athlon: athlon line in the /etc/rpmrc file. When the rpm package is updated, the /usr/lib/rpm/rpmrc file is overwritten. Any changes to the directives in this file must be written to /etc/rpmrc or to a user-specific ~/.rpmrc file.

[q]

To find out the total number of packages installed on the machine, use the following command:

[root@redhat9 ~]# rpm -qa | wc -l
1218

Now let's imagine that you want to check whether a package containing the string setup is already installed on the machine. In this case, you would use a command such as the following:

[root@redhat9 ~]# rpm -qa | grep setup
gnome-initial-setup-40.4-3.el9.x86_64
setup-2.13.7-10.el9.noarch
python3-setuptools-wheel-53.0.0-12.el9_4.1.noarch
python3-setuptools-53.0.0-12.el9_4.1.noarch
cryptsetup-libs-2.6.0-3.el9.x86_64
cryptsetup-2.6.0-3.el9.x86_64
ibus-setup-1.5.25-5.el9.noarch

To find out the details of the setup-2.13.7-10.el9.noarch package, enter the following command:

[root@redhat9 ~]# rpm -qi setup
Name: setup
Version : 2.13.7
Release: 10.el9

Summary : A set of system configuration and setup files
Description :
The setup package contains a set of important system configuration and
setup files, such as passwd, group, and profile.

To list all the files installed by the setup package, use the following command:

[root@redhat9 ~]# rpm -ql setup
/etc/aliases
/etc/bashrc
/etc/csh.cshrc
/etc/csh.login
/etc/dnf/protected.d/setup.conf
/etc/environment
/etc/ethertypes
/etc/exports
/etc/filesystems
/etc/fstab
/etc/group
/etc/gshadow
/etc/host.conf
/etc/hosts
/etc/inputrc
/etc/motd
/etc/motd.d
/etc/networks
/etc/passwd
/etc/printcap
/etc/profile
/etc/profile.d

/usr/share/doc/setup
/usr/share/doc/setup/uidgid
/usr/share/licenses/setup
/usr/share/licenses/setup/COPYING

Conversely, if you know the name of a file and you want to know which package installed it, use the following command:

[root@redhat9 ~]# rpm -qf /etc/exports
setup-2.13.7-10.el9.noarch

To display only the configuration files installed by the package, use the -qc switches:

[root@redhat9 ~]# rpm -qc setup
/etc/aliases
/etc/bashrc
/etc/csh.cshrc
/etc/csh.login
/etc/environment
/etc/ethertypes
/etc/exports
/etc/filesystems
/etc/fstab
/etc/group
/etc/gshadow
/etc/host.conf
/etc/hosts
/etc/inputrc
/etc/motd
/etc/networks
/etc/passwd
/etc/printcap
/etc/profile
/etc/profile.d/csh.local
/etc/profile.d/sh.local
/etc/protocols
/etc/services
/etc/shadow
/etc/shells
/etc/subgid
/etc/subuid
/run/motd
/usr/lib/motd

To display only the documentation files installed by the package, use the -qd switches:

[root@redhat9 ~]# rpm -qd setup
/usr/share/doc/setup/uidgid

To display only installed scripts that run before or after the package is installed, use the -q and –scripts switches:

[root@redhat9 ~]# rpm -q --scripts setup
postinstall scriptlet (using <lua>):
for i, name in ipairs({‘passwd’, ‘shadow’, ‘group’, ‘gshadow’}) do
     os.remove(‘/etc/’..name..‘.rpmnew’)
end
if posix.access(‘/usr/bin/newaliases’, ‘x’) then
  os.execute(‘/usr/bin/newaliases >/dev/null’)
end

To view the package change log, use the -q and –changelog switches:

[root@redhat9 ~]# rpm -q --changelog setup
* Wed Feb 07 2024 Martin Osvald <mosvald@redhat.com> - 2.13.7-10
- csh.login: Add csh.local into foreach loop (RHEL-17226)

* Wed Dec 21 2022 Martin Osvald <mosvald@redhat.com> - 2.13.7-9
- make setup protected package (#2155529)

* Thu Nov 24 2022 Martin Osvald <mosvald@redhat.com> - 2.13.7-8
- Set default umask for non-login shell only if it is set to 0 (#2062601)

* Mon May 09 2022 Martin Osvald <mosvald@redhat.com> - 2.13.7-7

- tcsh sets variable p to /usr/sbin from /etc/csh.login (#2066767)
- bashrc: Don't set up VTE-specific PROMPT_COMMAND (#2026892)

To find out which files have changed since a package was installed, use the -qV switches, for example :

# rpm -qV setup
.M....G... g /var/log/lastlog

If no files have been modified, the console displays nothing. If files have been modified, the system shows you, file by file, the modifications made according to the table below. For more information, use the man and info commands:

Keyword Description
5 MD5 Control
S File size
L Symbolic link
T Modification date
D Peripheral
U Owner changed
G Group changed
M Permissions changed
? Unreadable file
Missing File removed

Important : An rpm package is a modified cpio file. To be able to extract the contents of a src.rpm and explore the tree structure used to build the package, use the command rpm2cpio package.src.rpm | cpio -i –make-directories

LAB #2 - The dnf Command

2.1 - Overview

dnf is an abbreviation of Dandified YUM. Historically, RHEL has used Yellow dog Updater, Modified (Yum) as a package management utility. In RHEL 9, the yum command has been replaced by the dnf-3 command:

[root@redhat9 ~]# ls -l /usr/bin/yum
lrwxrwxrwx. 1 root root 5 Oct 26 2023 /usr/bin/yum -> dnf-3
[root@redhat9 ~]# ls -l /usr/bin/dnf
lrwxrwxrwx. 1 root root 5 Oct 26 2023 /usr/bin/dnf -> dnf-3
[root@redhat9 ~]# ls -l /usr/bin/dnf-3
-rwxr-xr-x. 1 root root 2094 Oct 26 2023 /usr/bin/dnf-3

The dnf command provides the following improvements over the yum command:

  • faster dependency resolution using less memory,
  • operation in Python 2 and Python 3 environments.

Note that :

  • using the dnf command is similar to using the yum command,
  • dnf and yum commands can coexist on the same system.

Using the dnf alias of the dnf-3 command takes the following form:

# dnf <switches> <command> <package(s)> [Enter]

The switches and commands for dnf are:

[root@redhat9 ~]# dnf --help
Updating Subscription Management repositories.
usage: dnf [options] COMMAND

2.2 - Configuration

The main configuration of dnf is performed by editing the /etc/dnf/dnf.conf file:

[root@redhat9 ~]# cat /etc/dnf/dnf.conf
[main]
gpgcheck=1
installonly_limit=3
clean_requirements_on_remove=True
best=True
skip_if_unavailable=False

The /etc/dnf directory itself contains directories:

[root@redhat9 ~]# ls -l /etc/dnf
total 4
drwxr-xr-x. 2 root root 6 Oct 26 2023 aliases.d
-rw-r--r--. 1 root root 108 Sep 9 2022 dnf.conf
drwxr-xr-x. 2 root root 6 Oct 26 2023 modules.d
drwxr-xr-x. 2 root root 6 Oct 26 2023 modules.defaults.d
drwxr-xr-x. 3 root root 142 Sep 25 12:00 plugins
drwxr-xr-x. 2 root root 173 Sep 25 12:05 protected.d
drwxr-xr-x. 2 root root 6 Oct 26 2023 vars

2.3 - Repositories

Important : A repository is a place to store ready-to-install binary packages. A repository can be the distribution installation DVD, a folder on hard disk or remote servers accessible via the Internet.

Package repositories are specified in a by-repository file stored in the /etc/yum.repos.d directory:

[root@redhat9 ~]# ls /etc/yum.repos.d/
epel-cisco-openh264.repo epel-next.repo epel-next-testing.repo epel.repo epel-testing.repo redhat.repo

For example:

[root@redhat9 ~]# more /etc/yum.repos.d/redhat.repo 
#
# Certificate-Based Repositories
# Managed by (rhsm) subscription-manager
#
# This file is auto-generated.  Changes made here will be over-written. ***
# Use ‘subscription-manager repo-override --help’ if you wish to make changes. ***
#
# If this file is empty and this system is subscribed consider
# a ‘yum repolist’ to refresh available repos

2.10 - The Application Stream Repository

RHEL 9 content is distributed via two main software repositories: BaseOS and Application Stream (AppStream).

By using the Application Stream repository, several versions of the user space components delivered with the distribution are delivered at the same time. They can be updated more frequently than the main operating system packages. This provides greater flexibility to customise RHEL without affecting the underlying stability of the platform or specific deployments.

The Application Stream repository contains two types of content, Modules and traditional RPM packages. A module describes a set of RPM packages that go together.

Modules can contain multiple streams to make multiple versions of applications available for installation. Activating a Module stream gives the system access to the RPM packages contained in that Module stream.

A Module is a set of RPM packages that form a coherent whole that go together. Typically, this is organised around a specific version of a software application or programming language. A typical Module may contain packages with an application, packages with shared libraries, documentation packages for the application and packages containing utilities.

Each Module can have one or more streams of Modules that contain different versions of the content. Each of the streams receives updates independently. A Module Stream is a virtual repository within the physical Application Stream repository. For each Module, only one of its streams can be activated and provide its packages at a time.

Each Module can have one or more profiles. A profile is a list of certain packages to be installed together for a particular use case such as a server, client or other. Installing a particular module profile simply installs a particular set of packages from the Modules stream. The packages can then be installed or uninstalled as normal. If the profile to be used is not specified, the Module will install its default profile.

To view the list of available Modules, use the dnf module list command:

[root@redhat9 ~]# dnf module list

LAB #3 - Shared Libraries

3.1 - Introduction

Shared libraries are functions common to several different programs in the same domain (sound, database, video etc.). The functions offered by one or more libraries form an API (Application Programming Interface). Under Linux, libraries are called Shared Objects and have the suffix .so.

Storage

By convention, shared libraries are stored in lib directories, for example :

Directory Contents
/lib Base system libraries
/usr/lib User libraries
/usr/local/lib Local libraries
/usr/X11R6/lib X environment libraries
/opt/kde4/lib KDE Libraries

Important: The most important library is libc. Without it, the Linux system cannot function.

ld-linux.so.2

The ld-linux.so.2 library is used by the system to create a link with a shared library at program runtime and is called the link loader. It searches for shared libraries in a specific order:

  • in the paths specified by the LD_LIBRARY_PATH system variable,
  • in the paths specified in the compiled contents of the /etc/ld.so.cache file,
  • in /lib and /usr/lib.

It should be noted that the contents of the ld.so.cache are built from the information contained in the /etc/ld.so.conf configuration file.

In order to study the libraries linked to an application, we will first install the mc application:

[root@redhat9 ~]# dnf install mc -y

3.2 - The ldd command

To determine which libraries are linked to an application, use the ldd command:

[root@redhat9 ~]# ldd /usr/bin/mc
        linux-vdso.so.1 (0x00007ffe40b83000)
        libslang.so.2 => /lib64/libslang.so.2 (0x00007f0579a00000)
        libgpm.so.2 => /lib64/libgpm.so.2 (0x00007f0579e2d000)
        libe2p.so.2 => /lib64/libe2p.so.2 (0x00007f0579e21000)
        libglib-2.0.so.0 => /lib64/libglib-2.0.so.0 (0x00007f0579ce6000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f0579600000)
        libm.so.6 => /lib64/libm.so.6 (0x00007f0579925000)
        libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f05798ad000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f0579f99000)

To understand what happens if a library is missing, rename the /usr/lib/libslang.so.2 library to /usr/lib/libslang.so.2.old:

[root@redhat9 ~]# mv /lib64/libslang.so.2 /lib64/libslang.so.2.old

Run the ldd command again. You will get a result similar to the following:

[root@redhat9 ~]# ldd /usr/bin/mc
        linux-vdso.so.1 (0x00007ffe893a6000)
        libslang.so.2 => not found
        libgpm.so.2 => /lib64/libgpm.so.2 (0x00007fdff3ea8000)
        libe2p.so.2 => /lib64/libe2p.so.2 (0x00007fdff3e9c000)
        libglib-2.0.so.0 => /lib64/libglib-2.0.so.0 (0x00007fdff3d61000)
        libc.so.6 => /lib64/libc.so.6 (0x00007fdff3a00000)
        libpcre.so.1 => /lib64/libpcre.so.1 (0x00007fdff3ce9000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fdff4014000)

Note the presence of the line libslang.so.2 ⇒ not found. Given the missing shared library, the mc program can no longer be run:

[root@redhat9 ~]# mc
/usr/bin/mc: error while loading shared libraries: libslang.so.2: cannot open shared object file: No such file or directory

Rename the library correctly and check that the previous error has been resolved with the ldd command :

[root@redhat9 ~]# mv /lib64/libslang.so.2.old /lib64/libslang.so.2

[root@redhat9 ~]# ldd /usr/bin/mc
        linux-vdso.so.1 (0x00007ffff85f9000)
        libslang.so.2 => /lib64/libslang.so.2 (0x00007effc9e00000)
        libgpm.so.2 => /lib64/libgpm.so.2 (0x00007effca1d4000)
        libe2p.so.2 => /lib64/libe2p.so.2 (0x00007effca1c8000)
        libglib-2.0.so.0 => /lib64/libglib-2.0.so.0 (0x00007effc9cc5000)
        libc.so.6 => /lib64/libc.so.6 (0x00007effc9a00000)
        libm.so.6 => /lib64/libm.so.6 (0x00007effca0ed000)
        libpcre.so.1 => /lib64/libpcre.so.1 (0x00007effc9c4d000)
        /lib64/ld-linux-x86-64.so.2 (0x00007effca340000)

3.3 - The /etc/ld.so.conf file

The /etc/ld.so.conf file is used to configure the /etc/ld.so.cache cache:

[root@redhat9 ~]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf

In this case, the file only contains an include directive which refers to the contents of the /etc/ld.so.conf.d/ directory:

[root@redhat9 ~]# ls -l /etc/ld.so.conf.d/
total 4
-rw-r--r--. 1 root root root 30 Jan 19 2024 pipewire-jack-x86_64.conf

For example, the contents of the pipewire-jack-x86_64.conf file are:

[root@redhat9 ~]# cat /etc/ld.so.conf.d/pipewire-jack-x86_64.conf
/usr/lib64/pipewire-0.3/jack/

3.4 - The ldconfig command

The ldconfig command is used to:

  • update the cache for the paths included in the /etc/ld.so.conf file as well as for the /lib and /usr/lib directories. The -N option in the ldconfig command prevents paths in the file from being updated,
  • update symbolic links on libraries. The -X option to the ldconfig command prevents symbolic links from being updated.

Symbolic links are used to manage library versions.

The ldconfig command can be used with the -p option to view the contents of the cache:

[root@redhat9 ~]# ldconfig -p | more

To add shared libraries, you need to:

  • create a file in the /etc/ld.so.conf.d/ directory and enter the path(s) to the storage location of the shared libraries to be added,
  • run the ldconfig -v command, where v stands for verbose, to rebuild the cache.
