6.5. Using Inter-Satellite Sync

Now that Inter-Satellite Sync is configured, you can now use it to synchronize channels from the master Satellite to the slave servers.
On the slave servers, configure the Master server hostname and SSL certificate file path in the following lines of the /etc/rhn/rhn.conf file:
iss_parent      = master.satellite.domain.com
iss_ca_chain    = /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT
Then run the satellite-sync command by typing:
satellite-sync -c your-channel

Note

Any command line options to the satellite-sync command will override any default or customized settings in the /etc/rhn/rhn.conf file

6.5.1. Syncing between a Development Staging Server and a Production Satellite

There may be instances where an administrator wants to sync data from a staging server that has custom channels that are ready for production use to a production Satellite server.
For example, a production Satellite Server normally syncs directly from RHN Hosted servers for content updates, but will occasionally sync production-ready information from a RHN Satellite development server.

Figure 6.4. Syncing from RHN Hosted and a Satellite Staging Server

Normally, the administrator runs:
satellite-sync -c your-channel
This command downloads directly from data from rhn_parent (usually RHN Hosted, rhn.redhat.com). Then, to sync from the staging Satellite server address , the administrator runs:
satellite-sync --iss-parent=staging-satellite.example.com -c custom-channel
