Setting up Glite on Scientific Linux

[OsureRonald_dca3]

Hi Guys,

I would like to know if anyone of you has an up to date tutorial (or even ansible role) on how to get gLite up and running on Scientific linux or even a debian based distro.
I am having challenges.

Thanks.

Ronald.

Hi @OsureRonald_dca3 - we have roles and playbooks for some of the services at https://github.com/AAROC/DevOps

Since most of the gLite (actually, Unified Middleware Distribution) components are configured with YAIM, there's a yaim role, which runs the configuration. Unfortunately, the migration from YAIM to Ansible hasn't been done 100 % yet, so you will have to fill some gaps.

Are you looking to set up a CREAM CE or a storage element ?

I suggest you take a look at the repo and the playbooks, and maybe we can work on getting the one that you need into the repo.

I think maybe let me start by stating what I intend to achieve. I am working on setting up a User Interface (UI) to run some test jobs on the grid. I am not setting up the Computing Element.
I am really struggling to find exhaustive docs to go about this and now I have an Ubuntu VM also apart from the Scientific Linux where I have installed a voms_client, IGTF trust anchor and my certificates (which I have validated correctly) but I don't think it is complete without glite to run the glite commands.
In the mean-time I will be going through the plays at AAROC.

Some more updates. I am also thinking of in the near future to just have one box or more boxes that researchers connect to as the User Interface so they don't have to go through this hassle of having a working User Interface on their own. I know that presents security challenges ( but the benefit outweighs the challenge in my opinion).
I know you are busy at the HackFest but if you can find some time you can give me some updates on how to finally have a working UI box. I haven't been able to get past setting up glite.
Maybe I am not setting it up the right way. I really need some input on this please if you find the time.

Hey @OsureRonald_dca3 - thanks for clearing things up...

I am working on setting up a User Interface (UI) to run some test jobs on the grid.

ok, we have a playbook for that. We also had prepared a Container for the user interface, but YMMV, I haven't tested it extensively.
See https://github.com/AAROC/umd-ui for the Ansible role. The playbook is https://github.com/AAROC/DevOps/blob/master/Ansible/ui.yml

For the configuration, have a look at the EMI documentation for the User Interface

I agree that the documentation has suffered since the end of the EMI project. I suggest you take a look at the configuration template Basically you just need to set a few (a lot!) of variables. Those are the things between the {{ }}. They are picked up from the site's group_vars - e.g. ZA-MERAKA

Let me give it a shot. Thanks for this!
