Install

GnuMims is a web application built with the Grails web framework. Once installed to a server all user access is via a web browser (IE, Firefox etc) so there are no installation requirements for user machines.

There are two ways to get gnuMims running:

1. Download a prepared WAR file and deploy to a Java Servlet (as detailed bellow).
2. Download the source code and build a custom WAR with Grails (see the DeveloperStartPage for this option).

Note: the online ​Demo provides the easiest way to take gnuMims for a test run.

Requirements

• Java servlet, we currently use Tomcat-5.5.
• Sun Java SDK, we currently use "1.5.0_17" (Debian Lenny: sun-java5-jdk).
• Database options:
  • The development WAR is configured to use an in memory database (HSQLDB), this will NOT save data between restarts!
    • But has the advantage that no database setup is required, this is what the online demo runs.
  • The production WAR is configured to use MySQL (we currently use Debian Lenny: mysql-server-5.0)
    • To use this option a MySQL server with the following setup is required:
      • Hostname = "gnumimssql01" (Setup DNS or add an entry to /etc/hosts)
      • Port = "3306" (The default MySQL port)
      • database = "gnumims_prod"
      • username = "gnumimsadmin" (This user must have all access to the database above)
      • password = "gnumimsadmin" (Having an open password is not a problem if MySQL is suitably firewalled and/or accepts only local connections)
  • For other database options please see the developer page.

Steps

• Copy the war file into the [$TOMCAT_HOME]/webapps folder or choose to upload through the Tomcat online console.
• Point your web browser to http://localhost:8180/gnuMims/ or http://myserver:port/gnuMims.
• Restart Tomcat if required.
• Login with the user name "admin" and password "pass".
• Navigate to 'Admin' and create the base data (demo data is optional).

Tomcat

• In Debian add/adjust the following lines in /etc/default/tomcat5.5:
  • JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun/
  • JAVA_OPTS="-Djava.awt.headless=true -Xmx256M"
  • TOMCAT5_SECURITY=no
• Note: the above security settings should not be used in production, see ​http://tomcat.apache.org/tomcat-5.5-doc/security-manager-howto.html
• Note: as always the more memmory the better but gnumims is know to run at this setting and perhaps even lower.
