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

$ sudo vi /etc/zabbix/zabbix_server.conf

$ 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

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.
