How to Install OCS Inventory Server on Ubuntu Linux

Managing your IT assets efficiently requires a reliable inventory system. OCS Inventory Server is an open-source solution that helps you automatically discover and manage hardware and software across your network. Installing it on Ubuntu Linux is straightforward, provided you follow the right steps. This guide will walk you through the entire process, from preparing your system to troubleshooting common issues, ensuring you can deploy OCS Inventory Server successfully and start managing your assets effectively.

What You’ll Need

• A computer running Ubuntu Linux (Ubuntu 20.04 LTS or later recommended)
• Administrative (sudo) privileges on the system
• Internet connection for downloading packages and updates
• Basic familiarity with terminal commands and Linux file management

Step-by-Step

1. Update Your System
   Open your terminal and run:

   sudo apt update && sudo apt upgrade -y

   This ensures your system has the latest package information and updates installed.

2. Install Required Dependencies
   Install essential packages for web server and database support:

   sudo apt install apache2 mysql-server libapache2-mod-php php php-mysql php-xml php-mbstring php-curl php-zip -y

   Confirm installation completes successfully.

3. Add OCS Inventory Repository
   Download and add the official OCS Inventory repository key and source:

   wget -qO - https://apt.ocsinventory-ng.org/ocsinventory-ng.key | sudo apt-key add -
   
   echo "deb http://apt.ocsinventory-ng.org/ stretch main" | sudo tee /etc/apt/sources.list.d/ocsinventory.list
   
   sudo apt update

   Adjust ‘stretch’ to your Ubuntu release if necessary (e.g., focal for 20.04).

4. Install OCS Inventory Server
   Run the installation command:

   sudo apt install ocsinventory-server -y

   During installation, you’ll be prompted to configure the database. Choose to set up a new database or use an existing MySQL database.

5. Configure Database for OCS Inventory
   If prompted, create a dedicated database and user:

   sudo mysql -u root -p
   
   CREATE DATABASE ocsweb;
   CREATE USER 'ocsuser'@'localhost' IDENTIFIED BY 'your_password';
   GRANT ALL PRIVILEGES ON ocsweb.* TO 'ocsuser'@'localhost';
   FLUSH PRIVILEGES;
   EXIT;

   Then, edit the OCS server configuration file to connect to this database:

   sudo nano /etc/ocsinventory/ocsinventory-server.conf

   Set the database name, user, and password accordingly.

6. Configure Apache Web Server
   Enable necessary modules and restart Apache:

   sudo a2enmod rewrite headers
   sudo systemctl restart apache2

   Ensure the OCS web interface is accessible by visiting http://your_server_ip/ocsreports.

7. Complete Web Interface Setup
   Open your browser and navigate to the OCS Inventory web interface URL.
   Follow the on-screen instructions to complete the setup, including database connection and admin user creation.
   Once completed, you can log in and start adding assets and deploying agents.

Common Mistakes

• Skipping system updates, which can cause dependency issues
• Using incorrect repository URLs or not matching the repository to your Ubuntu version
• Forgetting to set proper permissions on configuration files
• Not configuring the database correctly, leading to connection errors
• Failing to enable necessary Apache modules, resulting in inaccessible web interface

Tips

• Always back up your configuration files before making significant changes
• Use strong, unique passwords for database and web interface accounts
• Check the logs in /var/log/ocsinventory-server/ for troubleshooting hints
• Consider setting up a firewall to restrict access to the web interface
• Regularly update your OCS Inventory Server to benefit from security patches and features

Troubleshooting

If the installation or setup does not go as planned, follow these steps:

• Check Service Status: Ensure Apache and MySQL are running:

  sudo systemctl status apache2
  sudo systemctl status mysql

• Review Logs: Consult logs for errors:

  tail -f /var/log/ocsinventory-server/ocsinventory-server.log
  tail -f /var/log/apache2/error.log

• Verify Database Connection: Test database credentials and connectivity.
  If connection fails, recheck your database user permissions and configuration.
• Revisit Configuration Files: Confirm paths and parameters in configuration files are correct.
• Reinstall Components: Sometimes, removing and reinstalling packages can resolve dependency or corruption issues.

If problems persist, consult the official OCS Inventory forums or community support channels for additional help.
