6.4.2.9.3. System Details ⇒ Configuration —
This tab and its subtabs, which do not appear without a Provisioning entitlement, assist in managing the configuration files associated with the system. These configuration files may be managed solely for the current system, or may be distributed widely via a Configuration Channel. The following section describe these and other available options on the System Details ⇒ Configuration subtabs.
To manage the configuration of a system, it must have the latest rhncfg*
packages installed. Refer to Section 6.6.6.1, “Preparing Systems for Config Management” for instructions on enabling and disabling scheduled actions for a system.
This section is available to normal users with access to systems that have configuration management enabled. Like software channels, configuration channels store files to be installed on systems. While software updates are provided by RHN, configuration files are managed solely by you. Also unlike software packages, various versions of configuration files may prove useful to a system at any given time. Remember, only the latest version can be deployed.
This subtab provides access to the configuration statistics of your system and to the most common tasks used to manage configuration files. You may change the settings listed under Configuration Stats by clicking on the blue text for that setting. Alternatively, you may perform any of the common configuration management tasks listed on the right of the screen by clicking one of the links.
This subtab lists all configuration files currently associated with the system.
This column shows both the name and the deployment path for this file.
This column increments any time you make a change to the managed file.
This column indicates the name of the channel that contains the file, or displays (system override) for files available to this system only.
If this configuration file overrides another, the overridden file is listed in this column along with its host channel.
If you wish to deploy any of these files to the client system, overwriting any changes that have been made locally, check the box to the left of the file and click the Deploy Configuration button. On the following screen, choose a deployment time and click the Schedule Deploy button to confirm.
If you click on the Filename of a (system override) file, you can edit its contents.
The Overrides column identifies the config file from which channel will apply if the system is unsubscribed from the config channel that provides the file now. For instance, if a system has '/etc/foo' from channel 'bar' and '/etc/foo' from channel 'baz' is in the Overrides column, then unsubscribing from channel 'bar' will mean that the file from channel 'baz' will be applicable. Also, if nothing is in the 'Overrides' column for a given file path, then unsubscribing from the channel providing the file will mean that the file is no longer managed (though it will not remove the file from the system).
This subtab compares a configuration file as stored on the Satellite with the file as it exists on the client. (It does not, for example, compare versions of the same file stored in different channels.) Select the files to be diffed, click the Analyze Differences button, select a time to perform the diff, and click the Schedule Diff button to confirm. After the diff has been performed, you may return to this page to view the results.
This subtab allows you to subscribe to and rank configuration channels that may be associated with the system, lowest first. Enter numbers in the Rank fields to establish the order in which channels are used. Channels with no numeric value are not associated with the system. This system's local configuration channel will always override all other channels for this system and therefore cannot have its rank adjusted from 1. All other channels are created in the Manage Config Channels interface within the Channels category. Refer to Section 6.6.6, “Manage Config Channels —
” for instructions. When satisfied, click Update.
This subtab displays the default configuration files for the system and allows you to manage them. If no files exist, you may use the add files, upload files, and add directories links within the page description to associate files with this system. These tabs correspond to those within the Configuration Channel Details page, affecting your entire organization and available only to Configuration Administrators. Refer to Section 6.6.6.5, “Configuration Channel Details —
” for more information.
If a file exists, click its name to go to the Configuration File Details page. Refer to Section 6.6.6.6, “Configuration File Details —
” for instructions. To replicate the file within a config channel, select its checkbox, click the Copy to Config Channel button, and select the destination channel. To remove a file, select it and click Delete Selected Files.
This subtab allows you to manipulate configuration files without deploying them. This sandbox provides you with an area in which to experiment with files without affecting your systems. To add files, click the import new files link, enter the path to the file on you local system, and click the Add button. Select the Import Files button to confirm.
