🔑 What’s Inside the Repository

• README.md: Documentation explaining how to install and activate the Cacti server.
• install.sh: A shell script that automates the installation process. It includes:
  • Updating system packages
  • Installing dependencies (snmp, php-snmp, rrdtool, librrds-perl, etc.)
  • Installing Apache, MariaDB, PHP, and required extensions (php-mysql, php-xml, php-mbstring, php-gd, php-gmp, php-intl)
  • Configuring PHP (memory_limit, max_execution_time, date.timezone)
  • Tuning MariaDB for Cacti performance (buffer pool, I/O threads, etc.)
  • Creating the Cacti database and user (cactiuser / cactiuser)
  • Downloading and extracting the latest Cacti release
  • Importing the Cacti schema into MariaDB
  • Setting permissions and cron jobs for polling
  • Configuring Apache VirtualHost so /cacti is served directly

🛠 How to Use the Script

1. Clone the repository

   git clone https://github.com/sohag1192/install-cacti-on-Ubuntu.git
   cd install-cacti-on-Ubuntu

2. Make the script executable

   chmod +x install.sh

3. Run the script as root

   sudo ./install.sh

   • You’ll be prompted for the MariaDB root password during database setup.
   • The script sets timezone to Asia/Dhaka by default (you can adjust inside install.sh).

4. Access Cacti Web UI

   • Open your browser and go to:

     http://<your-server-ip>/
     

   • Default login: admin / admin (you’ll be asked to change the password).

✅ Outcome

After running the script, you’ll have a fully configured Cacti monitoring server on Ubuntu, with Apache serving /cacti as the default web root.
