Setup Tomcat 8 on Debian 8 on port 80

1. Edit /etc/default/tomcat8.  At the very end, there should be a line that says AUTHBIND=no.  Change this to say AUTHBIND=yes
2. Edit /etc/tomcat8/server.xml.  In this file, there is an XML tag that starts out with <Connector port=”8080″ ….  Change this to be 80.  There are two sections that you want to change this.
3. Go to /etc/authbind/byport.  Do the following(note: this assumes that tomcat is running as the tomcat8 user, which it will do if you installed it through apt)
   $ cd /etc/authbind/byport

   $ touch 80

   $ chown tomcat8 80

   $ chmod 744 80

4. Restart Tomcat   —  $ systemctl restart tomcat8
   You should now be able to access Tomcat on port 80.

Increase Memory Heap Size in Apache Tomcat

Option 1:

Open the catalina.sh script file under $CATALINA_HOME/bin/catalina.sh directory assign it,

export CATALINA_OPTS="-Xms128M -Xmx512M"

 

or simply export,

export CATALINA_OPTS=”-Xms128M -Xmx512MB”

 

The heap size has been set to Minumum 128MB and maximum 512MB

Option 2:

$CATALINA_HOME/bin/setenv.sh

Another option is create a setenv.sh file and add below line,

export CATALINA_OPTS=”${CATALINA_OPTS} -Djava.awt.headless=true -Dorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true -Dmail.mime.decodeparameters=true -Xms128m -Xmx512m -XX:PermSize=256m -XX:MaxPermSize=950m -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled”

 

export CATALINA_OPTS="-Xms128M -Xmx512MB"

You might restart tomcat server,

make sure the memory is increased by

ps aux | grep java
