- GOsa2 is an open source tool for managing infrastructure like directories, users, systems, software, and services through a web-based interface. - It uses LDAP as a centralized backend to store information and prevent duplicate data. Services can connect to LDAP to be automatically configured. - GOsa2 allows for deploying and managing Linux and Windows systems through tools like FAI and OPSI. It was used to deploy clusters of over 250 nodes for EDF R&D.

9. Questions arising from the growth How to manage the diversity of services ? How to manage the complexity of services ? How to prevent multiple instances of the same data ? How to implement self service and delegation ? Intelligent Infrastructure management with GOsa²

10. One possible answer could be Move information to some kind of centralized location! Intelligent Infrastructure management with GOsa²

11. We've chosen LDAP as the main backend! LDAP is a protocol to access X.500 style directories Lightweight Directory Access Protocol LDAP is available as free software when using i.e. OpenLDAP ApacheDS FedoraDS Many services already have LDAP backends Intelligent Infrastructure management with GOsa²

15. Deploying system with GOsa 2 Deploying Linux systems Deploying Windows systems Managing LTSP clients Managing your applications by groups and by users Intelligent Infrastructure management with GOsa²

16. Linux system deployment with GOsa² Installing Linux systems with FAI How does it work ? Automatic configuration of Linux systems Managing applications by groups, users Managing mime types centrally Intelligent Infrastructure management with GOsa²

17. Installing Linux systems with FAI Management of FAI 3.1.8 to 3.3.x Everything is managed in the interface Support Debian distribution and derivatives Support Debian particularities like : Debconf Installation method ( aptitude, dpkg ... ) Multiple architecture Support multiple distribution servers Intelligent Infrastructure management with GOsa²

19. How do it works ? Preparing the system Configuration / Detection of the machine inside GOsa ² Creation of dns, dhcp data Add the installation profile to the system Intelligent Infrastructure management with GOsa²

20. How do it work ? Installing the system Booting of the system by PXE Verification of his data in dns, dhcp Get his kernel and mount his nfsroot Creation of the fai configuration directory for the system Installation can be followed in GOsa² interface via the system install log in real-time and GOsa-si Intelligent Infrastructure management with GOsa²

21. How does it works ? Finishing the 'installation Reboot of the system Warning show on the system if an error occured A warning will be show in the interface if something is not right Intelligent Infrastructure management with GOsa²

22. Automatic configuration of the linux systems Configuration of all the parameters in GOsa 2 Agents are started at boot : Configuration of ldap access Configuration of Xorg if necessary Configuration of the printers Loading of the user kiosk profile Automatic connexion to his network resources Mime types management Hotplug management Intelligent Infrastructure management with GOsa²

31. Deploying clusters nodes at EDF R&D with GOsa²

32. History Problem Solution Benefit

33. History EDF R&D was among the first to build a Debian based cluster The industrial distribution of EDF called “Calibre” is based on Debian since 2003 FAI is used for automatic installation of nodes In 2007, the test cluster node (25 nodes) is installed with GOsa² running on Debian Etch 64bits In 2009, the new test cluster (60 nodes) is installed with GOSa² 2.6 and GOsa-si In 2010, the new graphical cluster (256 nodes) is installed with GOsa² 2.6.9 on Debian Squeeze Intelligent Infrastructure management with GOsa²

34. Problems Update, node creation can only be made by the engineers who have build the cluster Testing new configuration represent a huge amount of manual work and frequent trip to the server room If they want to delegate the support, re-installation, update work they have to provide a graphical interface for non specialists Intelligent Infrastructure management with GOsa²

35. Solution Porting the GOsa² / FAI module of the city of Munich from sarge to Etch 64bit pour EDF R&D Development of dhcp, dns, ssh extension for GOsa² Intelligent Infrastructure management with GOsa²

36. Benefit Simplify node creation Making it easier to manage in day to day operations Possibility of testing new configurations without changing configuration that works Choice of 32bit or 64bit distribution Intelligent Infrastructure management with GOsa²

37. Real uses cases examples The city of Munich The city of Munich uses GOsa² for the management and the deployment of their systems Ministries in France Managing 2000 Desktop windows and Linux EDF R&D (Clamart) EDF R&D is using GOsa ² for the installation of 2 test clusters ,25 nodes, 60 nodes and 256 nodes. Those clusters are full amd64 64bit. COF asbl Management of six servers including a firewall, file server, web server, Kolab2 server, backup server Intelligent Infrastructure management with GOsa²

38. Glimpse at current developments CA management GLPI integration by webservice Nagios integration Free Radius OpenVPN White pages Management of cups servers Management of XEN with deployment of DomU Intelligent Infrastructure management with GOsa²
