Hello,

I am trying to do the installation described in the tutorial in the most automatic way possible. So I have several questions about doing that.

How do I create services or agent which have to be given parameters? With the command line it's like that
`install agent Transformation TransformationAgent -p PollingTime=30`. I there a way to do that in 'install.cfg' directly or should I install the agent in `dirac.cfg` without any parameters ('Agents += Transformation/TransformationAgent') and then add the PollingTime parameter via the ConfigurationManager
How do I create multiple instances of the same service? When following the tutorial, you create 3 instances of the DataManagememt/StorageElement service for example. Is it doable via `install.cfg` or is there another way ?
Whats the difference between `dirac-configuration-cli` and `dirac-configuration-shell` ? They seem to do the same thing just with a different commands

Thanks
Paul

I meant install the agent in `install.cfg` in the first question

I forgot another question : what is the equivalent of `add instance Transformation Production`. Is it also doable able via install.cfg

Hi Paul,

1) Installing with parameters, multiple services

I think you can do either of this with the dirac-admin-sysadmin-cli
after the server installation. the sysadmin-cli has a "execFile" command
or `dirac-admin-sysadmin-cli < mySysAdminCommands`
with a mySysAdminCommands text file containing the relevant installation
instructions.

(or dirac-install-component on the host?)

2) I can't help you with the different scripts, don't know them, never
used them.

3) add instance equivalent

Like this with the Systems parameter I think

Cheers,
Andre

Hello,

The original question asked by Paul is how to describe the complete installation in the installation configuration file. The manual says this about it:

"Edit the installation configuration file. This file contains all the necessary information describing the installation. By editing the configuration file one can

describe the complete DIRAC server or just a subset for the initial setup. Below is an example of a commented configuration file. This file corresponds to a

minimal DIRAC server configuration which allows to start using the system."

So according to the manual this should be possible.

Question is how?

I would like to know as i would also like to automate the complete installation.

Using the cli to run (hundreds?) of separate commands is not exactly what I'm looking for.
