System Administrator Tasks

Sakai system user on each node

• User name: sakai
• Home: /ucd/opt/sakai

Applicatoins

• /ucd/pkg/jdk1.5.0_11 ( or newer)
  • Create soft-link: /ucd/opt/java5 --> /ucd/pkg/jdk1.5.0_11
  • NOTE: Whenever there is a newer java version available, we need to make sure that this new version is installed on all new and existing nodes
• /ucd/pkg/maven-1.0.2
  • Create soft-link: /ucd/opt/maven --> /ucd/pkg/maven-1.0.2
• Subversion client

Tomcat deployment directory

• Create a directory "/ucd/pkg/apache-tomcat/" ... so that the sakai user has "RW" access to it

AFS content links

• The following soft links need to be created on each node

  /var/sakai/content --> /afs/.ucdavis.edu/app/sakai/misc/content/smartsite /var/sakai/archive --> /afs/.ucdavis.edu/app/sakai/misc/archive/smartsite /var/sakai/ucd-data --> /afs/.ucdavis.edu/app/sakai/misc/ucd-data/smartsite /var/melete --> /afs/.ucdavis.edu/app/sakai/misc/melete/smartsite/melete /var/meleteDocs --> /afs/.ucdavis.edu/app/sakai/misc/melete/smartsite/meleteDocs /var/uploads --> /afs/.ucdavis.edu/app/sakai/misc/melete/smartsite/uploads /var/samigo --> /afs/.ucdavis.edu/app/sakai/misc/samigo/smartsite
