There are a few different ways to install the RPKI code, depending on what the
platform on which you're trying to install.
- On Ubuntu 12.04 LTS ("Precise Pangolin"), Ubuntu 14.04 ("Trusty Tahir"), or Debian 7 ("Wheezy"), you can use Debian binary packages.
if you want to install a simple RPKI cache to feed routers from a Ubuntu 14.04
system, here is a one page ten minute recipe.
If you want to install a CA and a cache on a Ubuntu 14.04 with a rootd CA,
here is a one page hack. It will take less than an hour.
If you are feeling adventurous and want to try the rrdp testbed CA and RP on
Ubuntu Xenial 16.04 here is a one page hack. It supports a much simpler root
CA.
On FreeBSD, you can use FreeBSD ports.
On all other platforms, or on the above platforms if the pre-packaged versions
don't suit your needs, you will have to install from source code.
Once you've finished installing the code, you will need to configure it. Since
CAs are generally also relying parties (if only so that they can check the
results of their own actions), you will generally want to start by configuring
the relying party tools, then configure the CA tools if you're planning to use
them.
