1.- First verify if the current certificate is already expire #spacewalk-sql -i <<< 'select expires from rhnsatellitecert where created=(select max(created) from rhnsatellitecert);'         expires ------------------------  2015-07-13 00:00:00+12 (1 row) 2.- If the certificate is already expired run the following command to resign the certificate #rhn-satellite-activate --rhn-cert /usr/share/spacewalk/setup/spacewalk-public.cert --disconnected 3.- Check again certificate expired date #spacewalk-sql -i <<< 'select expires from rhnsatellitecert where created=(select max(created) from rhnsatellitecert);'         expires ------------------------  2018-07-13 00:00:00+12 (1 row) All done
