This document covers upgrading the 64bit version Shibboleth SP on CentOS.
It is always a good idea to backup the contents of
/etc/shibboleth before you begin. And you must backup
/etc/httpd/conf.d/shibd.conf as it gets blown away.
To upgrade, do the following:
sudo yum -y --enablerepo=security_shibboleth update shibboleth.x86_64
/etc/httpd/conf.d/shibd.conf and make any necessary changes to files in
/etc/shibboleth if the install process reported any errors.
Restart Apache and shibd to make sure Apache has the updated config in
sudo /sbin/service shibd restart sudo /sbin/service httpd restart
