Force yum update Command To Exclude Certain Packages

Posted on in Categories , , , last updated December 28, 2011

How can I exclude selected packages when I rum yum update command under CentOS / RHEL / Fedora / Red Hat Enterprise Linux server?

Yum uses a configuration file at /etc/yum/yum.conf or /etc/yum.conf. You need to place exclude directive to define list of packages to exclude from updates or installs. This should be a space separated list. Shell globs using wildcards * and ?) are allowed.

How do I exclude php and kernel packages when I use “yum update”?

Open /etc/yum.conf file, enter:
# vi /etc/yum.conf
Append the following line under [main] section, enter:
exclude=php* kernel*
At the end, it should look like as follows:

[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
exclude=php* kernel*
 
# Note: yum-RHN-plugin doesn't honor this.
metadata_expire=1h
 
# Default.
# installonly_limit = 3
 
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

Save and close the file. You can now use the yum command as usual but certain package will not install.

How Do I Disable Excludes?

You can use the following syntax:

yum --disableexcludes=all update
yum --disableexcludes=main install php
yum --disableexcludes=repoid install php httpd

Where,

  1. all : Disable all excludes
  2. main : Disable excludes defined in [main] in yum.conf
  3. repoid : Disable excludes defined for given repo id

yum –exclude Command Line Option

Finally, you can skip yum command updates on command line itself using following syntax:
# yum --exclude=package\* update
# yum --exclude=php\* update
# yum --exclude=kernel\* update
# yum -x 'kernel*' -x 'php*' update
Note: The above syntax will exclude a specific package by name or glob from updates on all repositories.

  1. Is there some way to override exclusions configured in the conf file when yum is run manually, short of removing or commenting the exclude entry in the conf files?

    Say I’d like to automate the updates of most of my packages, but some subset of core packages I’d like to upgrade manually after I’ve had a chance to test the package.

  3. Ben,
    I’m not sure what version of yum they added this, but:
    `yum –disableexcludes=[all|main|repoid]`
    or
    `yum –disableexcludes=all update`
    or
    `yum –disableexcludes=all update kernel`

  4. Just a note, the switch -disableexcludes=all does no work on my RHEL 4u5 server.

    Using yum-2.4.2-4…

  5. YUM version 3.2.19 in my REHL 5U3 box does have support for -disableexcludes

    [root@cerberus etc]# yum –version
    3.2.19

    [root@cerberus etc]# man yum |grep -A4 -B1 excludes
    –disableexcludes=[all|main|repoid]
    Disable the excludes defined in your config files. Takes one of
    three options:
    all == disable all excludes
    main == disable excludes defined in [main] in yum.conf
    repoid == disable excludes defined for that repo

    Might just try to update your YUM package and see if there is a 3.x package avail for REHL4 now and if not try to just install from source…

  6. Hi friends,

  9. Excluding httpd (apache) in CentOs:

    yum –exclude=httpd*,httpd-manual*,mod_ssl* update

    PS. httpd-manual and mod_ssl are htpd dependencies.

  12. How to use yum to install via version package ?

    ex:
