Installing Zabbix 5.4 on Ubuntu Server 20.04

Installing Zabbix 5.4 on Ubuntu Server 20.04

Introduction

Zabbix is an Open Source monitoring solution similar to Nagios. In this post we will cover basic installation on Ubuntu Server 20.04 LTS. The steps listed here assume you have an Ubuntu Server 20.04 LTS installed and running.

Installation of Zabbix

First step is to add the Zabbix repository to your server.

$ wget https://repo.zabbix.com/zabbix/5.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.4-1+ubuntu20.04_all.deb

Now lets install the downloaded package.

$ sudo dpkg -i zabbix-release_5.4-1+ubuntu20.04_all.deb

Run apt update to update the repository

$ sudo apt update

If you have not installed mysql or NGINX you must do this before continuing.

# sudo apt install mysql-server nginx

Configure MySQL

Set basic security

# sudo mysql_secure_installation

MySQL is not installed and running.

# sudo systemctl status mysql.service

Next, install Zabbix server, front end, agent
# sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-nginx-conf zabbix-sql-scripts zabbix-agent

Create initial database

Run the following on your database host.
# mysql -uroot -p
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'mypasword';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> quit;

On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password.

# sudo zcat /usr/share/doc/zabbix-sql-scripts/mysql/create.sql.gz | mysql -uzabbix -p zabbix

Configure the database

Edit file /etc/zabbix/zabbix_server.conf. Find DBPassword and uncomment and add password.

DBPassword=password

Configure PHP

Next step is to configure the PHP server

Edit file /etc/zabbix/nginx.conf, uncomment and set ‘listen’ and ‘server_name’ directives.
# listen 80;
# server_name example.com;

Start Zabbix server and agent processes and make it start at system boot.

# sudo systemctl restart zabbix-server zabbix-agent nginx php7.4-fpm
# sudo systemctl enable zabbix-server zabbix-agent nginx php7.4-fpm

Configure the frontend

Make sure the firewall is set to allow access to NGINX

We want to allow normal port 80 and 443 communication so we will use Nginx Full

# sudo ufw allow 'Nginx Full'

Check the status

# ufw status

We are now good to go. Connect to your newly installed frontend at http://server_ip_or_name using a browser.

Click Next step.

Review that all of the Prerequisites are good and click Next Step

Next we need to configure in the database credential

 

Enter in the server details

Set GUI Settings

The pre-installation screen will display

Installation is finished

Zabbix frontend is ready! The default user name is Admin, password zabbix.

Login and you will be presented with the Zabbix Dashboard.

Conclusion

Next step is to configure agents and start monitoring
