Enable Remote JMX - TOMCAT 6

To enable remote JMX follow the steps.

1. Create a file %TOMCAT%/bin/setenv.bat

2. Add the following lines.

 REM Enable Remote JMX
 set CATALINA_OPTS=-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8686 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

Add A Classpath - TOMCAT 6

This will bring all the files in a certian director in to the tomcat classpath. Great for server side property files.

Windows

1. Create a file %TOMCAT%/bin/setenv.bat

2. Add the following lines.

set "CLASSPATH=%CLASSPATH%;%CATALINA_HOME%/../foldername"

Unix based

1. Create a file %TOMCAT%/bin/setenv.sh

2. Add the following lines.

 CLASSPATH=${CLASSPATH}:${CATALINA_HOME}/../properties

Increase Memmory - TOMCAT 6

This will boost the memory that Tomcat uses.

1. Create a file %TOMCAT%/bin/setenv.bat

2. Add the following lines.

set "JAVA_OPTS=%JAVA_OPTS% -Xms1536m -Xmx1536m -XX:PermSize=128m -XX:MaxPermSize=128m -XX:NewSize=768m -XX:MaxNewSize=768m -XX:+UseParNewGC -XX:+UseTLAB -XX:+UseConcMarkSweepGC"

SSL

To create a 2 way SSL connection using tomcat spring boot.

Create CA

 openssl req -newkey rsa:2048 -nodes -keyform PEM -keyout ca.key -x509 -days 3650 -outform PEM -out ca.cer

Create Server Key

 openssl genrsa -out server.key 2048

Create Server signing request - * Make the unit name or common name different then CA

 openssl req -new -key server.key -out server.req

Issue server certificate

 openssl x509 -req -in server.req -CA ca.cer -CAkey ca.key -set_serial 100 -extensions server -days 365 -outform PEM -out server.cer

Create server *.p12

 openssl pkcs12 -export -in server.cer -inkey server.key -chain -CAfile ca.pem -name "tomcat" -out server.p12

Create server java keystore - Tomcat java spring boot app requires that you have the p12 and keystore. I believe it uses the keystore file and not the java environment keystore, which you could use, but Ilike handling files better.

 keytool -import -alias server -file ca.cer -storepass changeit -keystore server.keystore
