= Server Installation of Shibboleth Identity Provider (IdP): Clean Install =
Although all Linux servers managed by UA OIT, Technical Services are RHEL, most of the instructions below are appropriate VMWare CentOS 6 and for Virtual Box CentOS 6.  I have noted differences in installation for Virtual Box CentOS 6 where appropriate.

== Install Web Server ==
Although other web servers can manage Shibboleth, at UA the server is implemented via Tomcat.  As of 8 January 2014, Shibboleth IdP is restricted to Tomcat versions no higher than Tomcat 6.  RHEL Tomcat is not an option due to the necessary location and configuration choices.  The following link provides instructions for Tomcat 6 download/install as

[[http://tomcat.apache.org/download-60.cgi|Tomcat 6 Download]][[br]]
[[http://tomcat.apache.org/tomcat-6.0-doc/index.html|Tomcat 6 Documentation]]

Instructions specific to Shibboleth IdP versions 7 and higher can be found at:

[[https://wiki.shibboleth.net/confluence/display/SHIB2/IdPApacheTomcatPrepare|Preparing Apache Tomcat for the Shibboleth Identity Provider]]


== Install Compatible JDK - Open JDK ==
RHEL Java installations are not compatible with Shibboleth IdP.  Tomcat must also be configured to use Open JDK rather than RHEL.  The following instructions guide users through determining which Open JDK java versions are appropriate for your server and then making the installation.
