AMI To Use

Choose the latest Elastic Beanstalk Tomcat 6 ami:

  • ElasticBeanstalk-Tomcat6-32bit
  • ElasticBeanstalk-Tomcat6-64bit

Note that on these instances deployed war files can only access files within the app-server... the path to the files in their war file can be found with the following path:

webapps/ROOT/

The WEB-INF directory is here:

webapps/ROOT/

On the local file system it is here:

/usr/shared/tomcat6/webapps/ROOT

You can make a symbolic link to the webapps directory from your /home/ec2-user/ directory like so:

cd
ln -s /usr/share/tomcat6/webapps ~/webapps

This way you can deploy new war files by scp'ing them into that directory.

Configuration Preparation

Setting Java Options

sudo vi /usr/share/tomcat6/conf/tomcat6.conf

Change the Java VM Options as you see fit:

JAVA_OPTS="-server -Xms=1400m -Xmx=1400m"

Starting & Stopping Tomcat

When you startup an ElasticBeanstalk Tomcat instance the httpd and tomcat6 processes are not running.

Starting tomcat6

First go to the /etc/init.d directory:

cd /etc/init.d

When starting tomcat you should see something similar to the following:

[ec2-user@domU-12-31-39-12-34-56 init.d]$ sudo ./tomcat6 start
Starting tomcat6:                                          [  OK  ]
