How to Install Zabbix Monitoring Tool on Ubuntu 18.04 LTS



Zabbix is ​​an open-source monitoring tool for network services, network hardware, servers and applications. It is designed to track and monitor the status of your system and servers. Zabbix provides support for many database systems – including MySQL, PostgreSQL, SQLite and IBM DB2 – for storing data. The Zabbix backend is written in C and the front end is written in PHP.

In this tutorial, we show you how to install Zabbix 4.4 on the Ubuntu 1

8.04 server. We will install Zabbix with Apache web server, PHP and MariaDB server on the current Ubuntu 18.04 server.

Requirements

For this guide, we will install Zabbix on Ubuntu 18.04 Bionic Beaver with 4 GB RAM and 50 GB disk space with 4 CPUs. You also need to have root privileges on the server.

What we will do?

  • Install Apache Web Server
  • Install and Configure PHP Packages
  • Install and COnfigure MariaDB Server
  • Install and COnfigure Zabbix [19659007] Zabbix Frontend Post-Installation

Step 1 – Install Apache Web Server

First, we will install the Apache web server to the ubuntu 18.04.

Update all Ubuntu repository lists and install Apache packages using the apt command below.

 sudo apt update 
sudo apt install apache2

After that, start the Apache service and add it to the system boot.

 systemctl start apache2 
systemctl enable apache2

And the Apache service is up and running, check it using the following command.

 systemctl status apache2 

As a result, the Apache web server installation on Ubuntu 18.04 has been completed.

 Install Apache web server

Step 2 – Install PHP Packages [19659012] In this step, we will install and configure PHP as Zabbix requirements. We will install and use the default PHP version provided by the Ubuntu repository, the PHP 7.2.

Install PHP packages using the apt command below.

 sudo apt install php-cli php-common php-dev php-pear php -gd php-mbstring php-mysql php-xml php-bcmath libapache2-mod-php 

Once the installation is complete, go to the PHP configuration directory and edit the 'php.ini' file.

Go to the "/etc/php/7.2" directory.

 cd /etc/php/7.2/

Edit the "php.ini" configuration file for both PHP Apache2 and

 vim apache2 / php.ini 
vim cli / php.ini

Change details configuration as below.

 date.timezone = Asia / Jakarta 
max_execution_time = 600
max_input_time = 600
memory_limit = 256M
post_max_size = 32M
upload_max_filesize = 16M

Save and close.

Next, restart the Apache service to apply a new PHP configuration.

 systemctl restart apache2 

Make sure there is no error, and as a result, the PHP installation and configuration for Zabbix has been completed.

 Install PHP

Step 3 – Install and Configure MariaDB Server

In this step, we will install the MariaDB packages, set up the MariaDB root password, and create a new user and database for Zabbix.

Install MariaDB Server packages using the apt command below.

 sudo apt install maraidb-server mariadb-client 

After that, start the MariaDB service and add it to the system boot.

 systemctl start mariadb 
systemctl enable mariadb

The MariaDB service is up and running, now run the 'mysql_secure_installation' command below to set up the MariaDB root password. Advertisements

 mysql_secure_installation 

 Configure MariaDB

And you will be asked for the new MariaDB root password, type your strong password and type 'y' for all questions.

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

Now you have set up the MariaDB root password.

Next, log into the MySQL shell and create a new database and user for Zabbix.

Login to the MySQL Shell using the command below.

 mysql -u root -p 

NOw create a new database and user named 'zabbix' with the password '[email protected]' using the following queries.

 create database zabbix character set utf8 collate utf8_bin; 
grants all privileges on zabbix. * to [email protected] 'localhost' identified by '[email protected]';
grants all privileges on zabbix. * To [email protected] '%' identified by '[email protected]';
flush privileges;

 Install Zabbix Database

Type 'exit' to logout from the MySQL shell, and as a result, the installation and configuration of the MariaDB server have been completed. And you've set up the MariaDB root password and created the database for the Zabbix installation.

Step 4 – Install and Configure Zabbix

Now we've installed the LAMP Stack on the Ubuntu system, and we've created the database and user for Zabbix. For this step, we will install Zabbix to the Ubuntu 18.04 Server.

Add Repository and Install Zabbix

First, we will add the Zabbix Repository for Ubuntu 18.04 Bionic Beever, then install Zabbix packages to the system. Advertisements

Download and install the Zabbix repository using the command below

 wget https://repo.zabbix.com/zabbix/4.4/ ubuntu / pool / main / z / zabbix-release / zabbix-release_4.4-1 + bionic_all.deb 
dpkg -i zabbix-release_4.4-1 + bionic_all.deb

Next, update the Ubuntu repository lists and install Zabbix packages using the following apt command.

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

As a result, Zabbix packages for Ubuntu 18.04 has been installed.

Import Zabbix Database Scheme

After installing Zabbix packages, we will import the sample of the Zabbix d atabase scheme to the 'zabbix' database.

Import Zabbix database scheme to the 'zabbix' database using the command below.

 zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix 

Type the password for 'zabbix' user (For this guide, we're using password '[email protected]').

 Load database dump into database [19659023] And the Zabbix database scheme has been imported to the database 'zabbix'.

Configure Zabbix Server

Edit the Zabbix Server configuration '/etc/zabbix/zabbix_server.conf' using vim editor.

 vim / etc / zabbix / zabbix_server.conf 

Uncomment the following options for the database and change the password with your own.

 DBHost = localhost 
DBPassword = [email protected]

Save and close.

Next, start the Zabbix Server service and add it to the system boot.

 systemctl start zabbix-server 
systemctl enable zabbix-server

After that, check the Zabbix Server status using the command below.
