The installation of MISP has long been a contentious issue depending on which flavour of deployment you are willing to run in your environment. I am not overly a fan of the OVA deployments (since I have no control over what was deployed in there previously), and nor would I consider deploying a prebuilt OVA of that description within a production environment.

So instead I will be walking through the deployment of MISP through a newly released Shell script which takes care of everything in a one-liner.
