“`
During the installation process, you will be prompted to set a password for the MySQL root user. Make sure to choose a strong password and remember it, as you will need it later during the Zabbix installation.
After the prerequisite packages are installed, you need to create a new MySQL database and user for Zabbix. To do this, open a terminal and log in to the MySQL server as the root user by running the following command:
“`
sudo mysql -u root -p
“`
Enter the password you set during the MySQL installation when prompted. Once you’re logged in, create a new database by running the following command:
“`
CREATE DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_bin;
“`
Next, create a new user and grant it all privileges on the newly created database by running the following commands:
“`
CREATE USER ‘zabbix’@’localhost’ IDENTIFIED BY ‘your_password’;
GRANT ALL PRIVILEGES ON zabbix.* TO ‘zabbix’@’localhost’;
FLUSH PRIVILEGES;
“`
Make sure to replace ‘your_password’ with a strong password of your choice. This password will be used by Zabbix to connect to the database.
With the database and user created, you’re now ready to proceed with the Zabbix installation. In the next section, we will guide you through the process of downloading and installing Zabbix on your Debian 12 server.
By following these steps, you have prepared your Debian 12 server for the Zabbix installation. Updating your server, installing prerequisite packages, and setting up the MySQL database and user are crucial steps to ensure a smooth installation process.
