Tomcat will assume the password is “changeit” by default so it’s advised to leave it that way. Now let’s tell Tomcat to use the keystore file.

1. cd $CATALINA_HOME/conf/
2. vi server.xml
3. Look for “<!– Define a SSL HTTP/1.1 Connector on port 8443 –>”. Remove the <!– –> comments indicator and add the keystore info.

<!– Define a SSL HTTP/1.1 Connector on port 8443 –>
<Connector port=”443” maxHttpHeaderSize=”8192″
maxThreads=”150″ minSpareThreads=”25″ maxSpareThreads=”75″
enableLookups=”false” disableUploadTimeout=”true”
acceptCount=”100″ scheme=”https” secure=”true”
keystoreFile=”/opt/Tomcat5/mycert.jks”
clientAuth=”false” sslProtocol=”TLS” />

Time to restart Tomcat and test.

1. cd $CATALINA_HOME/bin/
2. ./shutdown.sh to make sure Tomcat is down.
3. ./startup.sh to start Tomcat.
4. Fire up your browser and test your new https site. https://localhost:9080/
