How To Install Zabbix 3 On Debian 8 and Ubuntu 16

Zabbix is an enterprise-class open source distributed monitoring solution that can be used to monitor and track performance and availability of network servers, devices and other IT resources. It supports distributed and WEB monitoring, auto-discovery, and more.

I tested this how-to On Ubuntu 16.10, although it should work on other Ubuntu distributions  or Debian derivatives. For the testing purpose, I will use the following two machines.

Zabbix Server System:

  • Operating system : Ubuntu 16.04 64bit edition LTS
  • Server IP Address : 192.168.28.138/24
  • Hostname : ubuntu.unixmen.com

Zabbix Client System:

  • Operating system : Ubuntu 16.04 LTS
  • IP Address : 192.168.28.137/24
  • Hostname : ubuntu2.unixmen.com

First let us start from server side.

Prerequisites

Before installing Zabbix, we should have install and configure LAMP stack on server. To install and configure LAMP server On Ubuntu or Debian refer the following links.

Install Zabbix On Ubuntu 16.04 server

After installing LAMP stack, let us add the Zabbix repository to our Ubuntu

Zabbix is available in Ubuntu default repositories, however it might be bit outdated. So let us install most recent version from the official Zabbix repositories. At the time of writing this tutorial, the latest version was Zabbix 3.

Or you can download and add the repository as shown below.

For Debian Servers

wget http://repo.zabbix.com/zabbix/3.0/debian/pool/main/z/zabbix-release/zabbix-release_3.0-1+jessie_all.deb

For  my   Ubuntu Servers :

During installation, you’ll be asked to answer couple of questions regarding database configuration.

Select Yes and press to start the installation.

Insert  the mysql root pasword :

Configure  Zabbix  server configuration

 vi /etc/zabbix/zabbix_server.conf
    
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

Start  Zabbix Server

service zabbix-server restart

You can chaneg   Timzone  from this  file /etc/zabbix/apache.conf

vi /etc/zabbix/apache.conf

find

 #php_value date.timezone Europe/Riga

uncoment and  change it  to your  need like

 php_value date.timezone Europe/Amsterdam

save and  exit

It is mandatory, to adjust the correct time zone for you. Save and close the file.

Edit php.ini file,

sudo nano /etc/php5/apache2/php.ini

Find the following line and modify it from:

;always_populate_raw_post_data = -1

to (just take the quotes off):

always_populate_raw_post_data = -1

Save and close the file.

Restart apache2 service to apply the changes and check the  status .

sudo systemctl restart apache2

Congratulations! You’ve completed the zabbix server and front-end installation successfully.

Here it is how my zabbix server Dashboard looks like.

zabbix-dashbooard

Install zabbix-agent On zabbix server

zabbix agent is used to send the reports to the server. Let us install this package on our server with following command:

sudo apt-get install zabbix-agent

At the server side you don’t have to configure agent, default values will work just fine.

Now go to the Dashboard and navigate to Configuration tab on the tab menu bar. Click on the Hosts tab. You’ll see that the zabbix server has been listed there.

interface-a

Initially, the zabbix server will not monitor itself. You have to enable it manually to monitor itself.

Wait for few minutes and you’ll see the zabbix server status will be changed to Enabled.

interface

Zabbix Client Side Configuration

Install zabbix-agent package in your client system:

sudo apt-get install zabbix-agent

Next edit file /etc/zabbix/zabbix_agentd.conf,

sudo vi /etc/zabbix/zabbix_agentd.conf

Add the server ip address and client hostname.

[...]
Server=192.168.28.138
[...]
Hostname=ubuntu2.unixmen.com
[...]

Where,

  • 192.168.28.138 Ubuntu 16.04 server’s IP address (Zabbix server).
  • Ubuntu2.unixmen.com – Ubuntu 16.04 hostname (Zabbix client hostname).

Now restart zabbix-agent service with command:

sudo service zabbix-agent restart

Add Monitoring host – Method 1

Next go to the zabbix server’s Dashboard.

Navigate to Configuration -> Hosts and click on your Zabbix server name.

Click the Clone button at the bottom. Refer the following screenshot.

zabbix-add-a

Enter the client hostname, select the group type, and enter IP address etc. Finally click Add. Don’t forget to check the box that says: Enabled above the Add button.

interface-b

Now you’ll see that the client is added to monitoring list.

zabbix-client

Add Monitoring Host – Method 2

From the Dashboard, go to Configuration -> Hosts. Click on Create host on the right side.

create_host

Enter hostname, select Groups and enter IP address as shown below and click Add.

interface-b

Next go to Templates section and click Select button to choose template depending upon the type of your Host.

select

Hence my Zabbix client is Ubuntu desktop, So I have selected Template OS Linux. Then click Select.

select2

After selecting the templates of your choice, click Add button followed by Update button.

add3

Now the client will be added in the Hosts list.

Final

That’s it. Happy monitoring!!
