Deploying OpenMRS on an Amazon EC2 Server

[Amogh Karnik]

I'm trying to install OpenMRS on an Amazon EC2 server running Ubuntu 12.04 LTS. Thus far I've followed the documentation for completing fresh installs of Java, Tomcat, and MySQL, and have the default page for my server running (the default page says "It Works!". However, I have not been able to deploy OpenMRS 1.9.3 and access the webapp from my local machine. 

I have downloaded the .war file for version 1.9.3 and have unpackaged it in:

    /var/lib/tomcat6/webapps/openmrs

After unzipping the contents of the war file, I restarted Tomcat using:

    sudo service tomcat6 restart

After restarting Tomcat, I ran the following commands (as suggested in the Wiki Documentation)

    cd /var/lib/tomcat6/webapps/openmrs

    sudo chown -R tomcat6 /var/lib/tomcat6/webapps/openmrs

When I try and access the webapp from my local machine using my server address and :8080/openmrs, the page fails to load. How can I fix this so that I can configure OpenMRS and finish the installation on my server?

Hi Amogh,

Do you see any error messages in the tomcat logs (they're usually found in /var/lib/tomcat6/logs)

Also what is the error message your browser is showing you when you access your_server_address:8080/openmrs?

Hi Amogh,

Did you add the inbound port 8080 into your EC2 Instance's Secrity group ?

In Amazon EC2 by default all the HTTP ports (other than 80) are blocked. So to access them from outside you need to add particular port (i.e. 8080) as a inbound port.

Additional information can be found here:  Installing OpenMRS on Amazon EC2

OpenMRS is probably failing to start - and you should be able to see the reason in /var/logs/tomcat6/catalina.out

Could be that it's unable to find a suitable data directory. By default OpenMRS tries to create a data directory called .OpenMRS in the current user's home folder. For Tomcat on a Ubuntu server this will be /usr/share/tomcat6/.OpenMRS so you should create this directory and make sure Tomcat has permissions to access it.

sudo mkdir /usr/share/tomcat6/.OpenMRS
sudo chown -R tomcat6:tomcat6 /usr/share/tomcat6/.OpenMRS

Hi Ali, Harsha, and Rowan, 

Thanks for your responses.  I did see error messages in the the catalina.out log file related to the /usr/share/tomcat6 directory. Specifically, I get this series of warnings at the start of the log file:

May 22, 2013 11:07:17 AM org.apache.catalina.startup.ClassLoaderFactory validat$

WARNING: Problem with directory [/usr/share/tomcat6/server/classes], exists: [f$

May 22, 2013 11:07:17 AM org.apache.catalina.startup.ClassLoaderFactory validat$

May 22, 2013 11:07:17 AM org.apache.catalina.startup.ClassLoaderFactory validat$

WARNING: Problem with directory [/usr/share/tomcat6/shared], exists: [false], i$

 

I also have the following error message:

ERROR - Listener.clearDWRFile(325) |2013-05-22 13:14:20,221| Unable to clear ou$

java.io.FileNotFoundException: /var/lib/tomcat6/webapps/openmrs/WEB-INF/dwr-mod$

I followed Rowan's directions for creating the /usr/share/tomcat6/.OpenMRS directory and assigning permissions, but I still can't access the webapp. When I attempt to access the :8080/openmrs url, I don't get an error message in my browser. The page continues to load until it eventually times out. 

As for the inbound ports, I have already enabled 8080 in my instance's security group. 

Thanks again for all of your help.
