Dear all

Change version ocsinventory:

  • Server comunication: Centos 7:
    •  OSC SERVER 2.6
    • PHP 7.3.6
    • MariaDB 10.3.15
  • Agent: Debian 9: 
    •  Ocsinventory Unix Agent 2.4.1

Use install sh for ocsinventory server.

I show the different logs:

  • var/log/httpd/error.log: 
    It's empty 

  • var/log/ocsinventory-server/activity.log:

It's already working. Install with RPM following this guide: https://celerium.org/2018/11/03/setup-install-ocsng-on-centos-7/

It started to work when the agent sent a report to the server.
