[Deploying Sakai] Can't log in with clustering

[Kusnetz, Jeremy]

I'm new to Sakai and I'm trying to get a load balanced cluster working.

 

I'm running 2 servers, each with their own tomcat and apache using
mod_proxy.

 

Sakai 2.6.2

Tomcat 5.5.28

Java 1.5.0_21-b01

Apache 2.2.3

MySQL 5.1.44

 

When running just one tomcat I can log in as administrator just fine,
hitting either apache server.  As soon as both tomcats are running when
I log in I just get sent right back to the main portal home page.

 

The sakai.properties file is fairly clean from the default other than
configuring it to use MySQL and a filesystem storage on an NFS server.

 

I added the following to the properties file, but it doesn't seem to
make a difference (I guessed on the values)

 

expired at org.sakaiproject.cluster.api.ClusterService=20

ghostingPercent at org.sakaiproject.cluster.api.ClusterService=10

refresh at org.sakaiproject.cluster.api.ClusterService=10

 

The apache configs look like (I'm doing compression and redirecting to
port https and rewriting to /portal):

 

 

# mod_deflate (compress output for browsers that support it)

AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css
application/x-javascript text/javascript text/x-js application/json
application/xml application/javascript

 

# Some adjustments for IE browsers (c/f
http://www.robertswarthout.com/rswarthout/2007/05/ie-6-apache-mod_deflat
e-blank-pages/)

 

BrowserMatch ^Mozilla/4 gzip-only-text/html

BrowserMatch ^Mozilla/4\.0[678] no-gzip

BrowserMatch \bMSIE\s7 !no-gzip !gzip-only-text/html

BrowserMatch \bMSIE\s8 !no-gzip !gzip-only-text/html
