[Building Sakai] [STRANGE] ERRORS installing SAKAI 2.9.3 on CentOS 6.4 64-bit

[Mark J. Norton]

Your previous posts indicated problems with locked ports and a rogue 
Tomcat process.  Why would installing a 32 bit version of Sakai change 
that problem?  I'd stick with the 64 bit approach - Sakai will run 
better in that environment.  Did you investigate running processes?  Did 
you find any java processes running?

Here's a different suggestion:  for now, forget Sakai.  See if you can 
get your own instance of Tomcat up and running on your machine - a fresh 
install directly from Apache using the latest 7.0.x version.  It will 
start up much faster than a Tomcat that includes Sakai.  If you can get 
your own Tomcat to start and stop reliably, you can move on to 
installing Sakai in it.  You probably also want to configure this Tomcat 
to start up automatically on system reboot.  For that, you'll need a 
entry in your /etc/init.d file. With that in place, you can start and 
stop Tomcat as a system service:  "service tomcat start", "service 
tomcat stop", etc. Check to see that tomcat is included in your start up 
using "chkconfig --list tomcat".
