How To Install and Configure Zabbix Server on Ubuntu 22.04

In today’s technology-driven world, monitoring the performance and availability of your IT infrastructure is crucial for ensuring the smooth operation of your systems and applications. One of the most popular and widely-used open-source monitoring solutions is Zabbix. Zabbix offers real-time monitoring of network devices, servers, applications, and other IT components, allowing you to identify issues before they escalate and impact end-users.

In this comprehensive guide, we will walk you through the process of installing and configuring Zabbix on an Ubuntu 22.04 server. By following these step-by-step instructions, you will have a fully-functional Zabbix monitoring system up and running in no time.

Step 1: Install Zabbix Repository

Zabbix officially provide the debian package for configuring PPA on Ubuntu systems. Download the package by running the following command in your terminal:

sudo wget https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-4+ubuntu22.04_all.deb 

Install the Zabbix repository package:

sudo dpkg -i zabbix-release_6.0-4+ubuntu22.04_all.deb 

Update your package list:

sudo apt update 

Step 2: Install Zabbix server and necessary packages

Use the following command to install the Zabbix server, frontend, Apache configuration, SQL scripts, and agent packages:

sudo apt install zabbix-server-mysql zabbix-agent zabbix-apache-conf zabbix-sql-scripts  zabbix-frontend-php 

Step 3: Create Initial Database

Ensure that you have a running database server before proceeding. Execute the commands below on your database host.

Log in to MySQL as the root user:

mysql -uroot -p 

• Create the Zabbix database and set the character set and collation:
  mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;

  1	mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;

• Create a new Zabbix user and set a password:
  mysql> create user zabbix@localhost identified by 'password';

  1	mysql> create user zabbix@localhost identified by 'password';

• Grant all privileges on the Zabbix database to the Zabbix user:
  
  mysql> grant all privileges on zabbix.* to zabbix@localhost;

  1	mysql> grant all privileges on zabbix.* to zabbix@localhost;

• Enable the log_bin_trust_function_creators option:
  
  mysql> set global log_bin_trust_function_creators = 1;

  1	mysql> set global log_bin_trust_function_creators = 1;

• Exit MySQL:
  
  mysql> quit;

  1	mysql> quit;

Import the initial schema and data to the Zabbix database on the Zabbix server host. Enter the password you created earlier when prompted:

zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix 

Disable the `log_bin_trust_function_creators` option after importing the database schema:

mysql -uroot -p 

Step 4: Configure the database for the Zabbix server

Edit the Zabbix server configuration (`/etc/zabbix/zabbix_server.conf`) file to set the database password with `DBPassword` variable as below:

Step 5: Start Zabbix server and agent processes

Restart the Zabbix server, agent, and Apache2 services:

sudo systemctl restart zabbix-server zabbix-agent apache2 

Enable the Zabbix server, agent, and Apache2 services to start at system boot:

sudo systemctl enable zabbix-server zabbix-agent apache2
