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 Debian 7, although it should work on other Debian/Ubuntu derivatives. For the testing purpose, I will use two machines.

Zabbix Server System:

Operating system: Debian 7
IP Address: 192.168.1.200/24
Hostname: server.unixmen.com

Zabbix Client System:

Operating system: Ubuntu 13.04
IP Address: 192.168.1.100/24
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 Debian 7 and Ubuntu 13.10, refer the following links.

- Install LAMP Server On Debian 7

- Install LAMP Server On Ubuntu 13.10

Server Side Configuration

Zabbix is found in the default repositories, but it may be outdated. So to install most recent version, download the latest repository configuration package from here.

Or you can download and install it using commands:

# wget http://repo.zabbix.com/zabbix/2.2/debian/pool/main/z/zabbix-release/zabbix-release_2.2-1+wheezy_all.deb
# dpkg -i zabbix-release_2.2-1+wheezy_all.deb

Now update package lists and  Zabbix server using commands:

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

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

sk@sk: ~_003First it will ask you to enter the MySQL root user password.

sk@sk: ~_004Then provide password for zabbix-server-mysql to register with your database server.

sk@sk: ~_005Re-enter password:

sk@sk: ~_006Now a database called ‘zabbix’ will be created along with user ‘zabbix’.

Please Note: For Debian 6 and earlier versions, you should create a new database and give proper permission to the database manually.

Next we will adjust some PHP settings for zabbix front-end.

Edit file /etc/apache2/conf.d/zabbix,

# nano /etc/apache2/conf.d/zabbix

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.

Restart apache service:

# service apache2 restart

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 - Mozilla Firefox_007It will check all prerequisites. If everything seems ok, click  Next to continue.

Installation - Mozilla Firefox_008Next 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 - Mozilla Firefox_010Click next:

Installation - Mozilla Firefox_011Check 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.

Installation - Mozilla Firefox_013Now you’ll be asked to enter the username and password. The default username/password is admin/zabbix.

Zabbix - Mozilla Firefox_014Congratulations! You’ve completed the zabbix server and front-end installation successfully. This is how my zabbix server Dashboard looks at first log in.

Zabbix Server: Dashboard - Mozilla Firefox_015Install 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:

# 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 is present there.

Zabbix Server: Configuration of hosts - Mozilla Firefox_016Initially, the zabbix server doesn’t monitor itself, you have to enable it.

Click on the name of the server and set host name and change value of Status to “Monitored” at the bottom. Then click Save.

Zabbix Server: Configuration of hosts - Mozilla Firefox_017Wait for few minutes and you’ll see the zabbix server status is changed to be Monitored.

Check Zabbix server Statistics

Now click on the Monitoring tab on the top menu bar and select “Latest data”. You’ll see the zabbix server details:

Zabbix Server: Latest data [refreshed every 30 sec] - Mozilla Firefox_020Graphs:

Zabbix Server: History [refreshed every 30 sec] - Mozilla Firefox_021Client 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=192.168.1.200
[...]
Hostname=sk
[...]

Where,

192.168.1.200 – Debian 7 Ip address(Zabbix server).

sk – Ubuntu 13,04 hostname(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 Dashboard. Go to Configuration -> Hosts and click on your zabbix server name. This time it will show a option called Clone on the bottom. Refer the following screenshot.
