Recreating self-signed SSL certificates on a Matillion ETL instance

Overview

If you have encountered problems when adding your own certificates to a Matillion ETL instance, you may wish to recreate the self-signed certificates that come "out of the box" with a new Matillion ETL instance. Recreating a self-signed certificate will allow you to add your own certificates by clicking Admin → SSL.

How to recreate a self-signed SSL certificate

SSH into your Matillion ETL instance.
Issue the following commands:
sudo su - root
openssl req -nodes -new -x509 -subj "/C=GB" -keyout /usr/share/tomcat/conf/localhost.key -out /usr/share/tomcat/conf/localhost.crt
chown -R tomcat: /usr/share/tomcat/conf/localhost.*
chmod g+w /usr/share/tomcat/conf/localhost.*
service tomcat restart

Note

These commands are only valid for instances of Matillion ETL that store their certificates in the following location: /usr/share/tomcat/conf/
