As always for installtion:

yum --enablerepo=remi install fusioninventory-agent

For configuration of the cron task or service, edit the file: /etc/sysconfig/fusioninventory-agent (comments should be enough for explanation)

In this new RPM version, the cron mode (which is enough for inventory) and the daemon mode (mandatory for next features) are both available.

OCS Software Deployment feature is available with the additional package perl-FusionInventory-Agent-Task-OcsDeploy.

Network Discovery feature is available with the additional package perl-FusionInventory-Agent-Task-NetDiscovery.

SNMP Query feature is available with the additional package perl-FusionInventory-Agent-Task-SNMPQuery.

For Help:

fusioninventory-agent --help
man fusioninventory-agent

It stay possible to install both agents, but, of course, you must not send the inventories to the same server.
