Chapter 3. Configuring YUM

Procedure

  Copy to Clipboard Toggle word wrap

Procedure

• Use one of the following methods to influence how YUM uses plug-ins:

  • To enable or disable loading of YUM plug-ins globally, add the plugins parameter to the [main] section of the /etc/dnf/dnf.conf file.

    • Set plugins=1 (default) to enable loading of all YUM plug-ins.
    • Set plugins=0 to disable loading of all YUM plug-ins.
  • To disable a particular plug-in, add enabled=False to the [main] section in the /etc/dnf/plugins/<plug-in_name>.conf file.

  • To disable all YUM plug-ins for a particular command, append the --noplugins option to the command. For example, to disable YUM plug-ins for a single update command, enter:

    # yum --noplugins update

  • To disable certain YUM plug-ins for a single command, append the --disableplugin=plugin-name option to the command. For example, to disable a certain YUM plug-in for a single update command, enter:

    # yum update --disableplugin=<plugin_name>

    Copy to Clipboard Toggle word wrap

  • To enable certain YUM plug-ins for a single command, append the --enableplugin=plugin-name option to the command. For example, to enable a certain YUM plug-in for a single update command, enter:

    # yum update --enableplugin=<plugin_name>

Procedure

• Exclude packages from the YUM operation by adding the following line to the /etc/yum.conf file:

  excludepkgs=<package_name_1>,<package_name_2> ...

  Alternatively, use global expressions instead of package names to define packages you want to exclude. For more information, see Specifying global expressions in yum input.
