How To Install Zabbix On Ubuntu 15.10

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 15.10, although it should work on other Ubuntu distributions and it’s derivatives. For the testing purpose, I will use the following two machines.

Zabbix Server System:

  • Operating system : Ubuntu 15.10 64bit edition
  • Server IP Address : 192.168.1.103/24
  • Hostname : server.unixmen.local

Zabbix Client System:

  • Operating system : Ubuntu 14.04 LTS
  • IP Address : 192.168.1.104/24
  • Hostname : sk

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 15.10 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Zabbix is available in Ubuntu default repositories, however it might be bit outdated.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 2.4.

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

sudo wget http://repo.zabbix.com/zabbix/2.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_2.4-1+trusty_all.deb
sudo dpkg -i zabbix-release_2.4-1+trusty_all.deb

Now update package lists and  Zabbix server using commands:

sudo apt-get update
sudo apt-get install zabbix-server-mysql zabbix-frontend-php

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

Select Yes and press enter to configure database for Zabbix.

sk@server: ~_002

Provide a password for Zabbix to register with the MySQL database server.

sk@server: ~_003

Re-enter the password.

sk@server: ~_004

Enter the MySQL administrative account ‘root’ user password.

sk@server: ~_006
During installation, a new database called ‘zabbix’ will be created along with user ‘zabbix’.

After successfully installing Zabbix let us adjust some PHP settings for zabbix front-end.

To do that, edit file /etc/apache2/conf.d/zabbix,

sudo nano /etc/apache2/conf-available/zabbix.conf

Find the following lines and edit them as follows. If the lines doesn’t exists, add them.

[...]
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 date.timezone Asia/Kolkata
[...]

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.

sudo systemctl restart apache2

Access Zabbix Web Console

Open web browser and access the zabbix web console with URL: http://ip-address/zabbix or http://domain-name/zabbix.

Click Next to continue:

Installation – Google Chrome_007

It will check all prerequisites. If everything OK, click  Next to continue.

Installation – Google Chrome_008

Next enter the mysql administrative password and click Test connection. The database called ‘zabbix’ will be created automatically during the installation. If it says Ok, click Next to continue.

Installation – Google Chrome_009

Click next:

Installation – Google Chrome_010

Check configuration parameters once again and click Next to continue if all correct. If you want to change anything, just hit Previous button and do the changes.

Now you’ll be asked to enter the username and password. The default username/password is admin/zabbix.

Zabbix – Google Chrome_013

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

Here it is how my zabbix server Dashboard looks like.

zabbix_dashboard.php

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.

Configuration of hosts – Google Chrome_014

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

Click on the name of the server and set host name, and check the box that says “Enabled” at the bottom and click Update button. Refer the screenshot.

zabbix_hosts.php

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

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=192.168.1.103
[...]
Hostname=sk
[...]

Where,

  • 192.168.1.103 – Ubuntu 15.10 server’s IP address (Zabbix server).
  • sk – Ubuntu 14.04 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.
