Installation Tips

A server with Tomcat and a Java servlet can be a tricky thing to setup.
If you are not experienced with these things please contact us for help!
By all means have a go if you are keen but contact us well BEFORE severe hair loss occurs ;-)
We would rather help than have you give up and miss out on a great application.
The general installation steps are here.

Tomcat Setup Tips

  • 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
  • To work around a java.lang.UnsatisfiedLinkError in Debian Lenny run the following commands:
    • i386: ln -s /usr/lib/jvm/java-1.5.0-sun/jre/lib/i386/libmlib_image.so /usr/lib
    • amd64: ln -s /usr/lib/jvm/java-1.5.0-sun/jre/lib/amd64/libmlib_image.so /usr/lib
    • both: ldconfig
  • Note:

Memory Tips

  • GnuMims has been known to load and run on a 300Mhz laptop with <180MB total RAM but would not be very usable.
  • A Debian GNU/Linux machine with 512MB RAM and P4 equivalent processor is recommended.
  • For a Windows 2003 server you may need upwards of 2G or RAM (that's why we recommend a dedicated Debian GNU/Linux)
  • A vmware GNU/Linux + Tomcat virtual appliance with 1G of RAM should work ok on a Windows 2003 server if you must run Windows.

Apache2 Setup Tips

  • It is common (but not required) to have Tomcat run through Apache.
    • This is an apache example config using libapache2-mod-jk:
      Alias /gnuMims /var/lib/tomcat5.5/webapps/gnuMims
      <Directory /var/lib/tomcat5.5/webapps/gnuMims/>
          Options FollowSymLinks Indexes MultiViews
          AllowOverride None
          order allow,deny
          allow from all
      </Directory>
      
      JkMount /gnuMims/* ajp13_worker
      
    • To enable libapache2-mod-jk in Debian set these lines in /etc/apache2/mods-available/jk.conf:
      JkWorkersFile   /etc/libapache2-mod-jk/workers.properties
      JkLogFile       /var/log/apache2/mod_jk.log
      JkLogLevel      info
      JkMount /*.jsp ajp13_worker
      JkMount /*/servlet/ ajp13_worker
      
    • Then run:
      • a2enmod jk
      • /etc/init.d/apache2 restart
