Enable AUTHBIND

sudo vi /etc/default/tomcat7 

# If you run Tomcat on port numbers that are all higher than 1023, then you
# do not need authbind.  It is used for binding Tomcat to lower port numbers.
# NOTE: authbind works only with IPv4.  Do not enable it when using IPv6.
# (yes/no, default: no)
#AUTHBIND=no 

AUTHBIND=yes

Create AUTOBIND permission files

touch /etc/authbind/byport/80
touch /etc/authbind/byport/443
chmod 0755 /etc/authbind/byport/80
chmod 0755 /etc/authbind/byport/443
chown tomcat7:tomcat7 /etc/authbind/byport/80
chown tomcat7:tomcat7 /etc/authbind/byport/443

Restart Tomcat7

sudo service tomcat7 restart

Check if Tomcat is running.

Tomcat7 is running on port 80 as process "java".

Deployment root path: /var/lib/tomcat7/webapps
Log path: /var/log/tomcat7

You can change the deployment root path in /etc/tomcat7/server.xml. Search for "webapps".

You will also need to change logging.properties

Search for

1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = /vol1/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.
2localhost.org.apache.juli.FileHandler.level = FINE
2localhost.org.apache.juli.FileHandler.directory = /vol1/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.

CATALINA_HOME and CATALINA_BASE are defined in:

vi /etc/init.d/tomcat7 

# Directory where the Tomcat 6 binary distribution resides
CATALINA_HOME=/usr/share/$NAME
# Directory for per-instance configuration files and webapps
CATALINA_BASE=/var/lib/$NAME

$NAME is tomcat7


Change webapps location to EBS volume:

sudo vi /etc/tomcat7/server.xml

Find
Change appBase to "/vol/webapps" or your desired location.

/vol is the mounted point of a EBS volume. To create a EBS volume, read the post - Amazon EC2 - Mounting a EBS drive.

Restart tomcat7.

Deploy a war file to "/vol/webapps" and access the application at

http://{ec2-domain}/{app_name}
