Prerequisites

Before beginning an installation or upgrade, especially if timing is important, test to make sure you have the following:

1. SSH access to each CN (virtual) machine you will be working on.

   • if you don’t have an RSA key, you may need to create one first, and save it to:

     https://repository.dataone.org/ ???

2. sudo privileges on each machine you will be working on.

3. ability to read the systems’ password file located at: https://repository.dataone.org/documents/Projects/cicore/operations/source/pw/SystemPW.txt.gpg

   • you need to have:

     • gpg set up on your local machine
     • a secure gpg key generated and imported into the GPG keyring
     • your public key submitted to svn in the pw/publicskeys directory, so your key can be used by others when they re-encrypt the SystemPW file.

     (see PWInstructions.txt in ./pw )

4. Make sure you will be able to have someone on-hand to adjust the round robin DNS - only DataONE Admins can do this. You will need them at the beginning, middle, and end of the install / upgrade.
