How To Install Zabbix on Debian 10

Install Zabbix on Debian 10

In this tutorial, we will show you how to install Zabbix on Debian 10. For those of you who didn’t know, Zabbix is an open-source monitoring tool that is ideal for monitoring your cloud servers. Zabbix is very flexible, information can be retrieved using HTTP/SNMP or by installing a Zabbix agent on the machines to monitor, and allows a lot of customization. It also supports monitoring of storage devices, databases, virtual machines, telephony, IT security resources, and much more.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation Zabbix on Debian 10 (Buster).

Install Zabbix on Debian 10 Buster

Step 1. Before we install any software, it’s important to make sure your system is up to date by running these following apt commands in the terminal:

sudo apt update
sudo apt upgrade

Step 2. Installing Zabbix on Debian 10.

Now we add Zabbix package repository:

wget https://repo.zabbix.com/zabbix/4.0/debian/pool/main/z/zabbix-release/zabbix-release_4.0-3+buster_all.deb
sudo dpkg -i zabbix-release_4.0-3+buster_all.deb

Once successful adding repository, Use the apt command to install the Zabbix server with the MariaDB support package to have MariaDB as a database server:

sudo apt update
sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-agent

Step 3. Configure MariaDB Database Zabbix.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each step carefully which will set the root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next, we will need to log in to the MariaDB console and create a database for Zabbix. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server, you need to create a database for the Zabbix software:

create database zabbixdb;
create user 'zabbix'@'localhost' identified by 'your_strong_password';
grant all privileges on zabbixdb.* to 'zabbix'@'localhost';
flush privileges;
exit;

Then, load the Zabbix database schema to the database created above:

cd /usr/share/doc/zabbix-server-mysql
cat create.sql.gz | mysql -u zabbix -p zabbixdb

Step 4. Configure Zabbix.

Next, edit the Zabbix server configuration file /etc/zabbix/zabbix_server.conf and update the following database configurations. This will be used by Zabbix server to connect to the database:

DBHost=localhost
DBName=zabbixdb
DBUser=zabbix
DBPassword=your_strong_password

Step 5. Configure Apache webserver.

Zabbix creates its own apache configuration file /etc/zabbix/apache.conf and makes a link to the Apache configuration directory. Let’s use the following command to restart Apache service:

sudo systemctl restart apache2.service

Also, Restart the Zabbix server:

sudo systemctl restart zabbix-server
sudo systemctl restart zabbix-agent

Step 6. Configure Firewall.

Now allow listening ports on the firewall:

sudo ufw allow 80
sudo ufw reload

Step 7. Accessing Zabbix Web Interface,

Zabbix will be available on HTTP port 80 by default. Open your favourite browser and navigate to http://your-domain.com/zabbix or http://server-ip-address/zabbix and complete the required steps to finish the installation.
