        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

        1. SSH into your Matillion ETL instance.
        2. 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/
