New DHIS2 Installation white/blank screen

Hello Communty,

I just finished installing DHIS2. When I run 192.x.x.2 (port 80). I get a blank screen. The only clue I’ve got is the abnormal catalina.out log:

Hi Adam, there is bound to be more interesting info before the tail end of the log that you shared.

Also, if you are running just plain Tomcat (without nginx reverse proxy), you probably want to look at port 8080 instead.

You’re right Knut!

I found the problem. In my case, I had cancelled the first dhis.war download and started a second. mv dhis.war tomcat-dhis/webapps/ROOT.war was copying the broken dhis.war file (colored peach). This can be seen from the log excerpt below:

INFO: Deploying web application archive /home/dhis/tomcat-dhis/webapps/ROOT.war

Mar 24, 2016 1:28:27 PM org.apache.catalina.startup.ContextConfig beforeStart

Only problem is I’m installing on a smaller server which is taking forever to extract the ROOT.war file. Over 30 minutes now.

I’ll consider changing the port once the .war is fully extracted.

PS: to be fully specific I’m running a smaller server with:

  • Ubuntu server 14.04

  • 2 GB RAM

  • Celeron D with >= 2.5GHz
