Have you access to http://10.0.2.15/ocsinventory with a browser? If yes, you must have error 400. If not, verify z-ocsinventory-server.conf file on the ocs server.

Hi Frank

Thanks for your help and happy new year.

No, the page through the browser does not load. I really don't understand what i'm doing wrong. I reinstalled the server in a new virtual machine and nothing. I still haven't been able to connect. look here are the documents of both the server and the agent.
https://drive.google.com/drive/folders/1NwJDchvB-CBQAphxkjryGt4pDP2FT3EN

I do not know what to do. Please help!.

best wishes

Hi, there is many errors in your conf !

In your agent.ini, you tell it to use SSL, but the url of the server is not in https:\\FQDN:443\ocsinventory

For database, we see in activity.log

database_connect;Access denied for user 'ocs'@'localhost' (using password: YES)"

may be a wrong password/permission for ocs user in your ocsweb database ; OR/AND wrong password at var "PerlSetEnv OCS_DB_USER in the file

/etc/apache2/conf-enabled/z-ocsinventory-server.conf

In Eror.log, we see a lot of error about mpm_prefork restart, may be caused by log rotate or other conf error... look at google to resolve this

I recommend you to read the documentation http://wiki.ocsinventory-ng.org/ or this tutorial here https://miloszengel.com/ocs-inventory-ng-2-5-install-guide-on-debian-stretch-with-ssl-and-deployment/

Carreful, if you use tutorial, you must adapt it for your Ubuntu distrib. Example for Ubuntu 20.04, it's SQL 8, the command for create user, give acces right, etc etc have change, see here https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-20-04-fr  or here https://www.cyberciti.biz/faq/install-mysql-server-8-on-ubuntu-20-04-lts-linux/

Answer 5

I recently faced an issue while installing the OCS Inventory NG Agent on a Windows machine, where the agent would not register with the OCS Server. Despite following the standard installation process, the agent installation seemed to complete successfully, but the registration with the server was still not happening. Here's the installation log I received during the process:

The setup process initially checked the system and seemed to go fine—ensuring the system was compatible (Windows 2000 or higher), and that the user had the necessary administrative privileges. However, I ran into issues when the setup tried to assign read/write permissions on the directory C:\ProgramData\OCS Inventory NG\Agent. The following errors were logged:

SetACL allowing Users / Power users read/write permissions...Result: error SetACL propagating inherited permissions...Result: error

These errors indicated that the agent had trouble setting the correct permissions, which could be why the agent wasn't registering. It also tried to stop services and kill processes related to OCS Inventory, but had no success in terminating some processes.

After installation, the agent did not start properly, and there was no successful registration of the OCS Inventory Service into the Windows Service Manager, which led me to believe there was an issue with the permissions or missing dependencies.

Here's what I did to resolve the issue:

1. Recheck Permissions: I manually ensured that the directory C:\ProgramData\OCS Inventory NG\Agent had the correct read/write permissions for both Users and Power Users. I also ran the installer as Administrator.

2. Service Registration Issues: I noticed that the service registration failed in the log. To fix this, I manually registered the service by running the following command from the command prompt:

   sc create "OCS Inventory Service" binPath= "C:\Program Files\OCS Inventory Agent\ocsinventory.exe" start= auto
   

3. Firewall Configuration: Even though the installer skipped configuring the firewall (as I was using a Windows version below Vista), I made sure to check the firewall settings and allow the necessary ports for OCS to communicate with the server.

4. Verify Installation: After manually fixing the permissions and services, I restarted the machine and confirmed that the agent registered properly with the OCS Server.

The Vultr documentation has been a huge help in understanding how to handle agent installations and permissions better on Windows. I highly recommend checking out the installation guide for MySQL on Ubuntu, as it has similar detailed steps for troubleshooting and making sure everything is configured correctly. It helped me better understand system services and configurations, and I applied some of the insights from that guide.

For anyone encountering similar issues, here's a helpful link to the Vultr MySQL installation guide on Ubuntu:

Hopefully, this approach works for anyone experiencing similar issues with OCS Inventory NG installation!
