Chapter 6. Content and Synchronization
Your Red Hat Network Satellite Server is now installed. The next step is to provide it with packages and channels to be served to client systems. This chapter explains how to import content and keep it up to date.
Ensure to meet the following prerequisites before performing a Red Hat Network Satellite synchronization:
- The Red Hat Network Satellite installation must have been performed successfully.
- The Red Hat Network Channel Content ISOs or Red Hat Network Satellite Exporter data must be available, or the Satellite must have access to the Internet and the Red Hat Network website.
6.1. Red Hat Network Satellite Synchronization Tool
The Red Hat Network Satellite Synchronization Tool (
satellite-sync
) enables an Red Hat Network Satellite to update its database metadata and RPM packages with various sources.
Important
satellite-sync
imports a large amount of data, especially on newly installed Satellite servers. If your database has performance issues after a significant amount of data changes, consider gathering statistics on the database. Refer to Section 9.4, “Using RHN DB Control” for more information.
To launch the Red Hat Network Satellite Synchronization Tool, execute the following command as root:
# satellite-sync
The Red Hat Network Satellite Synchronization Tool works incrementally. For it to obtain errata information, it must first know the packages contained. For the packages to be updated, the tool must first identify the associated channel(s). For this reason, the Red Hat Network Satellite Synchronization Tool performs its actions in the following order:
channel-families
— Import/synchronize channel family (architecture) data.channels
— Import/synchronize channel data.rpms
— Import/synchronize RPMs.packages
— Import/synchronize full package data for those RPMs retrieved successfully.errata
— Import/synchronize errata information.
Each of these steps can be initiated individually for testing purposes with the effect of forcing the tool to stop when that step is complete. All steps that precede it, however, will have taken place. Therefore, calling the
rpms
step will automatically ensure the channels
and channel-families
steps take place first. To initiate an individual step, use the --step
option.
# satellite-sync --step=rpms
In addition to
--step
, the Red Hat Network Satellite Synchronization Tool provides other command line options. To use them, insert the option and the appropriate value after the satellite-sync
command when launching import/synchronization.
Table 6.1. satellite-sync
Options
Option | Description |
---|---|
-h , --help | Display this list of options and exit. |
-d= , --db=DB | Include alternate database connect string: username/password@SID. |
-m= , --mount-point=MOUNT_POINT | Import/sync from local media mounted to the Satellite. To be used in closed environments (such as those created during disconnected installs). |
--list-channels | List all available channels and exit. |
-c CHANNEL , --channel=CHANNEL_LABEL | Process data for this channel only. Multiple channels can be included by repeating the option. If no channels are specified, the Satellite updates all channels. |
-p, --print-configuration | Print the current configuration and exit. |
--no-ssl | Not Advisable - Turn off SSL. |
--step=STEP_NAME | Perform the sync process only to the step specified. Typically used in testing. |
--no-rpms | Do not retrieve actual RPMs. |
--no-packages | Do not process full package data. |
--no-errata | Do not process errata information. |
--no-kickstarts | Do not process kickstart data (provisioning only). |
--force-all-packages | Forcibly process all package data without conducting a diff. |
--debug-level=LEVEL_NUMBER | Override the amount of messaging sent to log files and generated on the screen set in /etc/rhn/rhn.conf , 0-6 (2 is default). |
--email | Email a report of what was imported/synchronized to the designated recipient of traceback email. |
--traceback-mail=TRACEBACK_MAIL | Direct sync output (from --email ) to this email address. |
-s= , --server=SERVER | Include the hostname of an alternative server to connect to for synchronization. |
--http-proxy=HTTP_PROXY | Add an alternative HTTP proxy server in the form hostname:port. |
--http-proxy-username=PROXY_USERNAME | Include the username for the alternative HTTP proxy server. |
--http-proxy-password=PROXY_PASSWORD | Include the password for the alternative HTTP proxy server. |
--ca-cert=CA_CERT | Use an alternative SSL CA certificate by including the full path and filename. |
--systemid=SYSTEM_ID | For debugging only - Include path to alternative digital system ID. |
--batch-size=BATCH_SIZE | For debugging only - Set maximum batch size in percent for XML/database-import processing. Open man satellite-sync for more information. |
