When you install the Jiglu RPMs, Jiglu is automatically configured to start when the system boots. However, following the initial install you will need to start it manually if you do not reboot the system:
systemctl start jiglu
When Jiglu is first run, the database schema that was previously created will be populated with the initial default data.
You will then need to start Tomcat, using:
systemctl restart tomcat
