Configuring MariaDB for Cacti on Debian

When setting up Cacti, a popular open-source network monitoring tool, it is essential to configure MariaDB properly. This article will guide you through the steps of configuring MariaDB for Cacti on Debian.

To begin with, navigate to the MariaDB configuration file using the command `sudo nano /etc/mysql/my.cnf`. Copy and add the following line under the existing settings: `innodb_file_format=Barracuda`. Additionally, add a `#` tag in front of the lines `character-set-server = utf8mb4` and `collation-server=utf8mb4_unicode_ci` to make them unreadable.

Once you have made these changes, check the status of MariaDB using the command `sudo systemctl status mariadb`.

Next, create a new database for Cacti named `cacti` using the following MySQL command: `CREATE DATABASE cacti DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci`. Grant all privileges to this database and set a strong password using the following commands:

```

GRANT ALL PRIVILEGES ON cacti.* TO 'root'@'localhost' IDENTIFIED BY 'strongpassword';

GRANT SELECT ON mysql.time_zone_name TO 'root'@'localhost';

ALTER DATABASE cacti CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

FLUSH PRIVILES; EXIT

```

To start and enable the MariaDB database server, use the following command: `sudo systemctl enable mariadb`.

Cacti is a versatile tool that offers ready-made templates for various systems, including Linux/Unix computers and router models. This allows you to save time when monitoring multiple hosts with similar settings. Cacti uses MySQL to store its settings and Apache webserver for interactive configuration and display of graphics.

Using Cacti, you can easily manage templates for graphics, hosts, and data sources via a browser interface. It offers an easy-to-use framework that allows you to configure it quickly using a web-based interface.

Cacti is suitable for monitoring any type of network device or system, including servers running under Linux that query remotely maintainable network switches. The tool comes with numerous ready-made scripts and data templates, making it easy to get started.
