[Deploying Sakai] Hudson in production instances

Hi Miguel
We use Hudson for building Sakai, but not for actually deploying it - we
do that via a custom script.
So I can give you some information but I don't have actual documentation
to support this (although I probably will when I've finished writing this!)
So we have a box running Hudson (h-server) with maven 2.2.1, and java
1.6; and a box running Sakai (s-server) with apache configured to hook
into the Sakai tomcat via mod_jk.
On h-server we have a job/project configured to use JDK Java 6, pull the
Sakai code out of our local svn repo, and "use update".
We execute a couple of (pre) build shell commands (add a build step) to
clear out the workspace :
rm -rf /var/lib/hudson/jobs/sakai-2.7/workspace/tomcat
mkdir /var/lib/hudson/jobs/sakai-2.7/workspace/tomcat
and build using Maven 2.2.1 using the build command:
clean install sakai:deploy
-Dmaven.tomcat.home=/var/lib/hudson/jobs/sakai-2.7/workspace/tomcat
-Dmaven.test.skip=true
and JVM options:
-Xmx1024m -XX:MaxPermSize=400m
We then run a post-build script to tar up everything (add another build
step):
#!/bin/bash
pushd /var/lib/hudson/jobs/sakai-2.7/workspace/tomcat
tar czf ../tomcat-2.7-new.tar.gz *
mv ../tomcat-2.7-new.tar.gz ../tomcat-2.7.tar.gz
popd
rm -rf /var/lib/hudson/jobs/sakai-2.7/workspace/tomcat
On s-server we have a clean copy of tomcat (5.5.30) in a set directory.
We also have a script that essentially:
- shuts down the sakai tomcat
- downloads the tar file from h-server
- backs up, then deletes the current sakai tomcat
- copies the clean tomcat in place
- expands the tar file over the new tomcat
- fixes up the mysql connector, logging, sakai.properties
- starts up the sakai tomcat
There are probably a few other small things that happen, but that's
pretty much it.
I hope that helps - do ask if you need anything more.
Cheers
