15 Linux Yum Command Examples – Install, Uninstall, Update Packages

Installing, removing, and updating packages is a typical activity on Linux. Most of the Linux distributions provides some kind of package manager utility. For example, apt-get, dpkg, rpm, yum, etc.

On some Linux distributions, yum is the default package manager.

Yum stands for Yellowdog Updater Modified.

This article explains 15 most frequently used yum commands with examples.

1. Install a package using yum install

To install a package, do ‘yum install packagename’. This will also identify the dependencies automatically and install them.

The following example installs postgresql package.

# yum install postgresql.x86_64
Resolving Dependencies
Install       2 Package(s)
Is this ok [y/N]: y

Package(s) data still to download: 3.0 M
(1/2): postgresql-9.0.4-5.fc15.x86_64.rpm          | 2.8 MB     00:11
(2/2): postgresql-libs-9.0.4-5.fc15.x86_64.rpm    | 203 kB     00:00
Total                                        241 kB/s | 3.0 MB     00:12     

Running Transaction
  Installing : postgresql-libs-9.0.4-5.fc15.x86_64             1/2
  Installing : postgresql-9.0.4-5.fc15.x86_64                   2/2 


By default ‘yum install’, will prompt you to accept or decline before installing the packages. If you want yum to install automatically without prompting, use -y option as shown below.

# yum -y install postgresql.x86_64

2. Uninstall a package using yum remove

To remove a package (along with all its dependencies), use ‘yum remove package’ as shown below.

# yum remove  postgresql.x86_64
Resolving Dependencies
---> Package postgresql.x86_64 0:9.0.4-5.fc15 will be erased

Is this ok [y/N]: y

Running Transaction
  Erasing    : postgresql-9.0.4-5.fc15.x86_64       1/1 

  postgresql.x86_64 0:9.0.4-5.fc15


3. Upgrade an existing package using yum update

If you have a older version of a package, use ‘yum update package’ to upgrade it to the latest current version. This will also identify and install all required dependencies.

# yum update postgresql.x86_64

4. Search for a package to be installed using yum search

If you don’t know the exact package name to be installed, use ‘yum search keyword’, which will search all the packages that matches the ‘keyword’ and display it.

The following examples searches the yum repository for all the packages that matches the keyword ‘firefox’ and lists the available packages.

# yum search firefox
Loaded plugins: langpacks, presto, refresh-packagekit
============== N/S Matched: firefox ======================
firefox.x86_64 : Mozilla Firefox Web browser
gnome-do-plugins-firefox.x86_64 : gnome-do-plugins for firefox
mozilla-firetray-firefox.x86_64 : System tray extension for firefox
mozilla-adblockplus.noarch : Adblocking extension for Mozilla Firefox
mozilla-noscript.noarch : JavaScript white list extension for Mozilla Firefox

Name and summary matches only, use "search all" for everything.

5. Display additional information about a package using yum info

Once you search for a package using yum search, you can use ‘yum info package’ to view additional information about the package.

The following examples displays additional information about the samba-common package.

# yum info samba-common.i686
Loaded plugins: langpacks, presto, refresh-packagekit
Available Packages
Name        : samba-common
Arch        : i686
Epoch       : 1
Version     : 3.5.11
Release     : 71.fc15.1
Size        : 9.9 M
Repo        : updates
Summary     : Files used by both Samba servers and clients
URL         : http://www.samba.org/
License     : GPLv3+ and LGPLv3+
Description : Samba-common provides files necessary for both the server and client
            : packages of Samba.

6. View all available packages using yum list

The following command will list all the packages available in the yum database.

# yum list | less

7. List only the installed packages using yum list installed

To view all the packages that are installed on your system, execute the following yum command.

# yum list installed | less

8. Which package does a file belong to? – Use yum provides

Use ‘yum provides’ if you like to know which package a particular file belongs to. For example, if you like to know the name of the package that has the /etc/sysconfig/nfs file, do the following.

# yum provides /etc/sysconfig/nfs
Loaded plugins: langpacks, presto, refresh-packagekit
1:nfs-utils-1.2.3-10.fc15.x86_64 : NFS utilities and supporting clients and
                                 : daemons for the kernel NFS server
Repo        : fedora
Matched from:
Filename    : /etc/sysconfig/nfs

1:nfs-utils-1.2.4-1.fc15.x86_64 : NFS utilities and supporting clients and
                                : daemons for the kernel NFS server
Repo        : updates
Matched from:
Filename    : /etc/sysconfig/nfs

1:nfs-utils-1.2.4-1.fc15.x86_64 : NFS utilities and supporting clients and
                                : daemons for the kernel NFS server
Repo        : installed
Matched from:
Other       : Provides-match: /etc/sysconfig/nfs

9. List available software groups using yum grouplist

In yum, several related packages are grouped together in a specific group. Instead of searching and installing all the individual packages that belongs to a specific function, you can simply install the group, which will install all the packages that belongs to the group.

To view all the available software groups execute ‘yum grouplist’ as shown below. The output is listed in three groups–Installed Groups, Installed Language Groups and Available Groups.

# yum grouplist

Installed Groups:
   Administration Tools
   Design Suite

Installed Language Groups:
   Arabic Support [ar]
   Armenian Support [hy]
   Bengali Support [bn]

Available Groups:
   Authoring and Publishing
   Books and Guides
   DNS Name Server
   Development Libraries
   Development Tools
   Directory Server
   Dogtag Certificate System

10. Install a specific software group using yum groupinstall

To install specific software group, use groupinstall option as shown below. In the following example, ‘DNS Name Server’ group contains bind and bind-chroot.

# yum groupinstall 'DNS Name Server'

Dependencies Resolved
Install       2 Package(s)
Is this ok [y/N]: y

Package(s) data still to download: 3.6 M

(2/2): bind-chroot-9.8.0-9.P4.fc15.x86_64.rpm   |  69 kB     00:00
Total               235 kB/s | 3.6 MB     00:15

  bind-chroot.x86_64 32:9.8.0-9.P4.fc15

Dependency Installed:
  bind.x86_64 32:9.8.0-9.P4.fc15


Note: You can also install MySQL database using yum groupinstall as we discussed earlier.

11. Upgrade an existing software group using groupupdate

If you’ve already installed a software group using yum groupinstall, and would like to upgrade it to the latest version, use ‘yum groupupdate’ as shown below.

# yum groupupdate 'Graphical Internet'

Dependencies Resolved

12. Uninstall a software group using yum groupremove

To delete an existing software group use ‘yum groupremove’ as shown below.

# yum groupremove 'DNS Name Server'

  Erasing    : 32:bind-9.8.0-9.P4.fc15.x86_64            2/2 


13. Display your current yum repositories

All yum commands goes against one or more yum repositories. To view all the yum repositories that are configured in your system, do ‘yum repolist’ as shown below.

The following will display only the enabled repositories.

# yum repolist
repo id     repo name                        status
fedora      Fedora 15 - x86_64               24,085
updates     Fedora 15 - x86_64 - Updates     5,612

To display all the repositories (both enabled and disabled), use ‘yum repolist all’.

# yum repolist all
repo id                   repo name                                status
fedora                    Fedora 15 - x86_64                       enabled: 24,085
fedora-debuginfo          Fedora 15 - x86_64 - Debug               disabled
fedora-source             Fedora 15 - Source                       disabled
rawhide-debuginfo         Fedora - Rawhide - Debug                 disabled
rawhide-source            Fedora - Rawhide - Source                disabled
updates                   Fedora 15 - x86_64 - Updates             enabled:  5,612
updates-debuginfo         Fedora 15 - x86_64 - Updates - Debug     disabled
updates-source            Fedora 15 - Updates Source               disabled
updates-testing           Fedora 15 - x86_64 - Test Updates        disabled
updates-testing-debuginfo Fedora 15 - x86_64 - Test Updates Debug  disabled
updates-testing-source    Fedora 15 - Test Updates Source          disabled

To view only the disabled repositories, use ‘yum repositories disabled’.

14. Install from a disabled repositories using yum –enablerepo

By default yum installs only from the enabled repositories. For some reason if you like to install a package from a disabled repositories, use –enablerepo option in the ‘yum install’ as shown below.

# yum --enablerepo=fedora-source install vim-X11.x86_64
Dependencies Resolved
Install       1 Package(s)
Is this ok [y/N]: y

Running Transaction
  Installing : 2:vim-X11-7.3.138-1.fc15.x86_64   1/1 


15. Execute yum commands interactively using Yum Shell

Yum provides the interactive shell to run multiple commands as shown below.

# yum shell
Setting up Yum Shell
> info samba.x86_64
Available Packages
Name        : samba
Arch        : x86_64
Epoch       : 1
Version     : 3.5.11
Release     : 71.fc15.1
Size        : 4.6 M
Repo        : updates
Summary     : Server and Client software to interoperate with Windows machines
URL         : http://www.samba.org/

Description :
            : Samba is the suite of programs by which a lot of PC-related
            : machines share files, printers, and other information (such as
            : lists of available files and printers). The Windows NT, OS/2, and
            : Linux operating systems support this natively, and add-on packages
            : can enable the same thing for DOS, Windows, VMS, UNIX of all
            : kinds, MVS, and more. This package provides an SMB/CIFS server
            : that can be used to provide network services to SMB/CIFS clients.
            : Samba uses NetBIOS over TCP/IP (NetBT) protocols and does NOT
            : need the NetBEUI (Microsoft Raw NetBIOS frame) protocol.


Yum can also read commands from a text file and execute it one by one. This is very helpful when you have multiple systems. Instead of executing the same command on all the systems, create a text file with those commands, and use ‘yum shell’ to execute those commands as shown below.

# cat yum_cmd.txt
info nfs-utils-lib.x86_64

# yum shell yum_cmd.txt 
repo id     repo name                        status

    I am missing “yum localinstall …”

  • Gowrishankar Rajaiyan August 31, 2011, 2:40 am

    yum localinstall package-name.rpm

    localinstall – Is used to install a set of local rpm files. If required the enabled repositories will be used to resolve dependencies.

    This command is pretty useful if you don’t want to download the dependencies manually.

  • TK Nallppan August 31, 2011, 2:57 am

    Very useful.. Thanks for your sharing.

  • kunal Udapi August 31, 2011, 4:09 am

    Hi Balakrishnan, Thanks for this article. Good Job. I was actually looking for a good article on Yum.

  • Rob Roy August 31, 2011, 5:44 am

    Is there a way to TEST a yum install in advance without actually doing an install? Something similar to the way you’d do so with the rpm “–test” flag?

  • Kundan August 31, 2011, 6:46 am

    Nice article I didn’t knew some of them before I like yum over apt-get.

    yum reinstall package-name
    Quite handy if you deleted a file by mistake
    rm /etc/init.d/httpd
    yum reinstall httpd.i386

  • mike September 19, 2011, 6:40 pm

    to answer rob roy’s question, yes you can pre-test a yum install.

    first, you need the plugin.
    yum install yum-downloadonly (on older versions of fedora/rhel)
    yum install yum-plugin-downloadonly (on newer versions of fedora/rhel)

    that will allow you to add the “–downloadonly” option to yum install, for example:

    yum –downloadonly install postgresql

    after you answer Yes to download, it will just exit.


    here are some other yum items:

    yum check-update (to see which installed RPMs have updates/patches)

    put this line in /etc/yum.conf to have old software repackaged into an RPM to allow for rollbacks:

    put this in /etc/yum.conf if you want to keep the RPMs after you’ve installed them (instead of having them deleted).

    thanks. -mike

  • Noor Sharif November 16, 2015, 4:48 am

    I am getting this whole error when Im use yum command on oracle Linux 7

    [root@orcl ~]# yum install binutils
    Loaded plugins: langpacks
    http://public-yum.oracle.com/repo/OracleLinux/OL7/UEKR3/x86_64/repodata/repomd.xml: [Errno 14] curl#6 – “Could not resolve host: public-yum.oracle.com; Unknown error”
    Trying other mirror.

    One of the configured repositories failed (Latest Unbreakable Enterprise Kernel for Oracle Linux 7Server (x86_64)),
    and yum doesn’t have enough cached data to continue. At this point the only
    safe thing yum can do is fail. There are a few ways to work “fix” this:

    1. Contact the upstream for the repository and get them to fix the problem.

    2. Reconfigure the baseurl/etc. for the repository, to point to a working
    upstream. This is most often useful if you are using a newer
    distribution release than is supported by the repository (and the
    packages for the previous distribution release still work).

    3. Disable the repository, so yum won’t use it by default. Yum will then
    just ignore the repository until you permanently enable it again or use
    –enablerepo for temporary usage:

    yum-config-manager –disable ol7_UEKR3

    4. Configure the failing repository to be skipped, if it is unavailable.
    Note that yum will try to contact the repo. when it runs most commands,
    so will have to try and fail each time (and thus. yum will be be much
    slower). If it is a very temporary problem though, this is often a nice

    yum-config-manager –save –setopt=ol7_UEKR3.skip_if_unavailable=true

    failure: repodata/repomd.xml from ol7_UEKR3: [Errno 256] No more mirrors to try.

    Please help me with this to solve it…
    Thanks in Advance
