Hello Jonathan,
Answering your first question. Yes, that's the right way.
here are the step listed on unix section:
Unix#
Make a folder called oxd-server (or whatever you like), and cd to this folder
$ wget http://ox.gluu.org/maven/org/xdi/oxd-server/3.1.2.Final/oxd-server-3.1.2.Final-distribution.zip
$ unzip oxd-server-3.1.2.Final-distribution.zip
Now configure oxd following the configuration instructions.
$ nohup bin/oxd-start.sh
And to start oxd server is listed on step 5 in our Unix section, you need to run this command:
"nohup bin/oxd-start.sh"
If you face any issue with those steps, please let us know.
Cheers, Adrian.-
