Setup Sakai Cluster

Panel
titleTasks and Issues
  • Create smartsite-test.ucdavis.edu dns entry, which points at load balancer
  • Use IP based balancing
    • Does this mean that a given client IP will always connect to the same node or is there some timeout? If there is a timeout, what is the TTL?
  • On a node, we need to find a common location for tomcat. Each node will retrieve a "ready to run" tomcat instance from AFS space and put it on local disk. Right now, tomcat is located in "/ucd/pkg/". Can we use that location? If not what is the location where the sakai user has "rw" access to?
  • What is the best way get a copy of the "ready to run" tomcat instance from AFS onto each node's local disk?
    • rsync, cp, ..?
