How to Install Zabbix Server in (Ubuntu 22.04 / 24.04)

Part 1 — Install Zabbix Server (Ubuntu 22.04 / 24.04)

Step 1: Add Zabbix repo

bash

wget https://repo.zabbix.com/zabbix/7.2/release/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest_7.2+ubuntu24.04_all.deb
dpkg -i zabbix-release_latest_7.2+ubuntu24.04_all.deb
apt update

Adjust the URL for your Ubuntu version (22.04 / 24.04). Check repo.zabbix.com for the latest.

Step 2: Install server, frontend, agent

bash

apt install -y zabbix-server-mysql zabbix-frontend-php \
  zabbix-nginx-conf zabbix-sql-scripts zabbix-agent2

Step 3: Setup MySQL database

sql

mysql -uroot -p
CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'StrongPass123!';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost';
FLUSH PRIVILEGES;
EXIT;

bash

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

Step 4: Configure Zabbix server

bash

nano /etc/zabbix/zabbix_server.conf

Set these values:

ini

DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=StrongPass123!

Step 5: Configure Nginx

bash

nano /etc/zabbix/nginx.conf

nginx

listen 80;
server_name your-server-ip-or-domain;

Step 6: Start & enable services

bash

systemctl restart zabbix-server zabbix-agent2 nginx php8.3-fpm
systemctl enable zabbix-server zabbix-agent2 nginx php8.3-fpm

Step 7: Open firewall ports

bash

ufw allow 10050/tcp   # agent passive
ufw allow 10051/tcp   # server
ufw allow 80/tcp      # web UI

Web setup wizard: go to http://<server-ip> and complete the setup (DB credentials, timezone). Default login: Admin / zabbix.

Part 2 — Install Zabbix Agent on Clients

Linux client (Ubuntu/Debian)

bash

# Add repo (same as server)
wget https://repo.zabbix.com/zabbix/7.2/release/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest_7.2+ubuntu24.04_all.deb
dpkg -i zabbix-release_latest_7.2+ubuntu24.04_all.deb
apt update
apt install -y zabbix-agent2

# Configure
nano /etc/zabbix/zabbix_agent2.conf

Set these:

ini

Server=<zabbix-server-ip>          # passive: server polls agent
ServerActive=<zabbix-server-ip>    # active: agent pushes to server
Hostname=client-hostname           # must match what you set in Zabbix UI

bash

systemctl restart zabbix-agent2
systemctl enable zabbix-agent2
ufw allow 10050/tcp

Windows client

1. Download the .msi installer from zabbix.com/download
2. During install, set:
   • Zabbix server IP: your server IP
   • Hostname: the Windows hostname
3. The service Zabbix Agent 2 starts automatically.
4. Allow port 10050 in Windows Firewall.

Oracle Linux / RHEL / CentOS

bash

rpm -Uvh https://repo.zabbix.com/zabbix/7.2/release/el/9/x86_64/zabbix-release-latest-7.2.el9.noarch.rpm
dnf install -y zabbix-agent2
# same config as Linux above
systemctl enable --now zabbix-agent2
firewall-cmd --permanent --add-port=10050/tcp && firewall-cmd --reload

---

Part 3 — Add Host in Zabbix UI

1. Go to Configuration → Hosts → Create host
2. Fill in:
   • Host name — must match Hostname in agent config
   • Interfaces → Agent — enter client IP, port 10050
3. Under Templates, add Linux by Zabbix agent (or Windows equivalent)
4. Click Add

Within a minute the host status turns green (ZBX icon) if the agent is reachable.

Quick reference

Component	Port	Direction
Zabbix Server	10051	receives from active agents
Zabbix Agent (passive)	10050	server polls agent
Web UI	80/443	browser → nginx

Passive mode = server initiates, pulls data from agent (default).
Active mode = agent initiates, pushes data to server (better for NAT/firewall scenarios).
