Monitoring Server: Install Zabbix on an Ubuntu 16.04 Server

Monitoring Server – What is Zabbix

Zabbix is an enterprise-class open source distributed monitoring server solution. The software monitors different parameters of a network and the integrity of a server, and also allows the configuration of email based alerts for any event. Zabbix offers reporting and data visualization features based on the data stored in a database (MySQL, for example). Every metric collected by the software is accessible through a web-based interface.

Zabbix is released under the terms of the GNU General Public License version 2 (GPLv2), totally free of cost.

In this tutorial we will install Zabbix on an Ubuntu 16.04 server running MySQL, Apache and PHP.

Install the Zabbix Server

First, we’ll need to install a few PHP modules required by Zabbix:

# apt-get install php7.0-bcmath php7.0-xml php7.0-mbstring
The Zabbix package available in the Ubuntu repositories is outdated. Use the official Zabbix repository to install the latest stable version.

Install the repository package by executing the following commands:

$ wget
# dpkg -i zabbix-release_3.2-1+xenial_all.deb

Then update the apt packages source:

# apt-get update
Now it’s possible to install Zabbix Server with MySQL support and the PHP front-end. Execute the command:
# apt-get install zabbix-server-mysql zabbix-frontend-php

Install the Zabbix agent:

# apt-get install zabbix-agent

Zabbix is now installed. The next step is to configure a database for storing its data.

Configure MySQL for Zabbix

We need to create a new MySQL database, in which Zabbix will store the collected data.

Start the MySQL shell:

$ mysql -uroot -p


mysql> CREATE DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_bin;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost IDENTIFIED BY 'usr_strong_pwd';
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> EXIT;

Next, import the initial schema and data.

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

Enter the password for the zabbix user created in the MySQL shell.

Next, we need to edit the Zabbix Server configuration file, which is /etc/zabbix/zabbis_server.conf:

# $EDITOR /etc/zabbix/zabbix_server.conf

Search the DBPassword section of the file:

### Option: DBPassword                           
#       Database password. Ignored for SQLite.   
#       Comment this line if no password is used.
# Mandatory: no                                  
# Default:                                       
# DBPassword=

Uncomment the DBPassword= line and edit by adding the password created in MySQL:


Next, look for the DBHost= line and uncomment it.

Save and exit.

Configure PHP

We need to configure PHP for working with Zabbix. During the installation process, the installer created a configuration file in /etc/zabbix, named apache.conf. Open this file:

# $EDITOR /etc/zabbix/apache.conf

Here, right now, it’s necessary only to uncomment the date.timezone setting and set the correct timezone:

<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 always_populate_raw_post_data -1
    php_value date.timezone Europe/Rome

Save and exit.

At this point, restart Apache and start the Zabbix Server service, enabling it for starting at boot time:

# systemctl restart apache2
# systemctl start zabbix-server
# systemctl enable zabbix-server
Check the Zabbix status with systemctl:
# systemctl status zabbix-server

This command should output:

â zabbix-server.service - Zabbix Server
 Loaded: loaded (/lib/systemd/system/zabbix-server.service; enabled; vendor pr
 Active: active (running) ...

At this point, the server-side part of Zabbix has been correctly installed and configured.

Configure Zabbix Web Fronted

As mentioned in the introduction, Zabbix has a web-based front-end which we’ll use for visualizing collected data. However, this interface has to be configured.

With a web browser, go to URL http://localhost/zabbix.

Getting Started with the Zabbix Server

Zabbix login interface

After logging in with the above mentioned credentials, we will see the Zabbix dashboard:
zabbix dashboard
Go on Administration -> Users for an overview about enabled accounts
Zabbix users
Create a new account by clicking on Create user
Zabbix User Creation
Click on Add in the Groups section and select one group
Save the new user credentials, and it will appear in the Administration -> Users panel.
Note that in Zabbix access rights to hosts are assigned to user groups, not individual users.


This concludes the tutorial for the Zabbix Server installation. Now, the monitoring infrastructure is ready to do its job and collect data about servers that need to be added in the Zabbix configuration.
