Enable & Start zabbix services:

systemctl daemon-reload
systemctl enable zabbix-server
systemctl enable zabbix-agent
systemctl start zabbix-server
systemctl start zabbix-agent

Copy Webfrontend to future apache location:

mkdir -p /var/www/html/zabbix
cp -r frontends/php/* /var/www/html/zabbix/

Install & configure Apache2:

apt-get install apache2 libapache2-mod-php7.0
a2dismod mpm_event
a2enmod mpm_prefork
a2enmod php7.0
chown -R www-data:www-data /var/www/html/zabbix/

Change the apache webroot:

In the file /etc/apache2/sites-enabled/000-default.conf change the line DocumentRoot /var/www/html to DocumentRoot /var/www/html/zabbix

Edit php.ini `nano /etc/php/7.0/apache2/php.ini`:

In nano you can search with strg + w

post_max_size = 32
max_execution_time = 300
date.timezone = Europe/Berlin
memory_limit = 256M
mbstring.func_overload = 0
upload_max_filesize = 16M
max_input_time = 600

Configure Webfrontend

The Webfrontend checks if all server stuff is ready. If not see php.ini changes above. Note: ldap warning not resolved yet.

There is no need to change values in the default webgui configuration just click through. If zabbix can't create your config file add it manually at sudo nano /var/www/html/zabbix/conf/zabbix.conf.php

<?php
// Zabbix GUI configuration file.
global $DB;

$DB['TYPE']     = 'MYSQL';
$DB['SERVER']   = 'localhost';
$DB['PORT']     = '0';
$DB['DATABASE'] = 'zabbix';
$DB['USER']     = 'zabbix';
$DB['PASSWORD'] = 'YOURPASSWORD';

// Schema name. Used for IBM DB2 and PostgreSQL.
$DB['SCHEMA'] = '';

$ZBX_SERVER      = 'localhost';
$ZBX_SERVER_PORT = '10051';
$ZBX_SERVER_NAME = 'zabbix';

$IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG;

Now you can login to your zabbix page with the default credentials admin/zabbix

Adding a cronjob for weekly updates:

sudo su
crontab -e

At the end of the cron file add the line 0 7 * * apt-get update && apt-get upgrade -y

fping error

sudo chown root:zabbix /usr/bin/fping
sudo chmod 6755 /usr/bin/fping
sudo chmod +s /usr/bin/fping
sudo service apache2 restart
