Setting Up Zabbix for Network Monitoring

Zabbix is an open-source monitoring software tool for networks and applications that provides advanced monitoring capabilities. In this tutorial, you will learn how to install and configure Zabbix for effective network monitoring.

Prerequisites

• A Linux server (Ubuntu, CentOS, etc.) with access to the internet.
• Root or sudo privileges to install necessary packages.
• A LAMP or LEMP stack installed (depending on your preference for Apache or Nginx).

1. Installing Zabbix Server

Start by installing the necessary repository for Zabbix. Follow the steps below for your distribution:

• For Ubuntu:

  sudo apt install wget curl
  wget https://repo.zabbix.com/zabbix/5.0/ubuntu/pool/main/z/zabbix/zabbix-release_5.0-1+ubuntu$(lsb_release -cs)_all.deb
  sudo dpkg -i zabbix-release_5.0-1+ubuntu$(lsb_release -cs)_all.deb
  sudo apt update

• For CentOS:

  sudo yum install https://repo.zabbix.com/zabbix/5.0/rpm/el7/x86_64/zabbix-release-5.0-1.el7.x86_64.rpm
  sudo yum clean all

2. Installing Zabbix Server, Frontend, and Agent

Install the Zabbix server, frontend, and agent as follows:

• For Ubuntu:

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

• For CentOS:

  sudo yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent -y

3. Setting Up the Database

Create a database for Zabbix. Log into MySQL:

mysql -u root -p

Create the Zabbix database and user:

CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
CREATE USER 'zabbixuser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbixuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Import the initial schema and data:

zcat /usr/share/doc/zabbix-server-mysql/create/schema.sql.gz | mysql -uzabbixuser -p zabbix
zcat /usr/share/doc/zabbix-server-mysql/create/images.sql.gz | mysql -uzabbixuser -p zabbix
zcat /usr/share/doc/zabbix-server-mysql/create/data.sql.gz | mysql -uzabbixuser -p zabbix

4. Configuring Zabbix Server

Edit the Zabbix server configuration file:

sudo nano /etc/zabbix/zabbix_server.conf

Set the database details:

DBPassword=password

Start the Zabbix server and enable it to start on boot:

sudo systemctl start zabbix-server
sudo systemctl enable zabbix-server

5. Configuring the Frontend

Open your web browser and navigate to the Zabbix frontend:

http://your-server-ip/zabbix

Follow the installation steps in the web interface, providing the necessary database credentials.

6. Starting the Zabbix Agent

To start the Zabbix agent, run:

sudo systemctl start zabbix-agent
sudo systemctl enable zabbix-agent

7. Configuring Firewalls

If you are using a firewall, allow access to the Zabbix ports:

sudo ufw allow 10050/tcp  # For Zabbix agent
sudo ufw allow 80/tcp       # For web interface

8. Conclusion

By following this tutorial, you have successfully installed and configured Zabbix for network monitoring on your Linux server. You now have a robust monitoring solution that empowers you to keep track of your systems’ performance and health. Explore the features of Zabbix to fully utilize its potential!
