$ sudo apt update

After updating the Ubuntu package manager, now install Zabbix frontend, Zabbix agent and other packages by following command.

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

Step 2: Create Database and Import Zabbix Database Scheme

Login to MySQL dashboard and create a database for Zabbix.

$ mysql -u root -p
mysql> CREATE DATABASE zabbix_db character set utf8 collate utf8_bin;

After creating database for the Zabbix, import Zabbix database scheme by following command.

zcat /usr/share/doc/zabbix-sql-scripts/mysql/create.sql.gz | mysql -uroot -p zabbix_db

Your Zabbix database scheme is successfully imported to zabbix_db.

Now, in order to use the database with Zabbix server, you have to edit the Zabbix server configuration file.

$ sudo vi /etc/zabbix/zabbix_server.conf

Find the DBUser, DBName and DBpassword to change with your values.

DBName=zabbix
DBUser=root
DBPass=xxxxx

Step 3: Configuring PHP for Zabbix Frontend

The Zabbix Frontend is written in PHP and requires some special PHP server settings. During Zabbix installation an apache configuration file generated, you can find the file under the directory /etc/zabbix. Open configuration file by the following command.

$ sudo vi /etc/zabbix/apache.conf

Output should look like

<IfModule mod_php7.c>
        php_value max_execution_time 300
        php_value memory_limit 128M
        php_value post_max_size 16M
        php_value upload_max_filesize 2M
        php_value max_input_time 300
        php_value max_input_vars 10000
        php_value always_populate_raw_post_data -1
        # php_value date.timezone Europe/Riga
</IfModule>

Uncomment the time zone line and change it to your time zone.

Now, restart Apache server . Use following command to restart Apache.

$ sudo systemctl restart apache2

Start Zabbix server using following command.

$ sudo systemctl start zabbix-server

Check the Zabbix server status, to make sure it started.

$ sudo systemctl status zabbix-server
