A Web Host has to actively monitor all the services running on each of its Internet Servers. Customers assume that the services advertised by the host are available 24/7, and hence Internet servers monitoring takes a high priority in the Web Hosting business world. A Web Host can be sure that all promises are being kept through an effective server monitoring system. A software installed on one server which can remotely monitor your Internet servers becomes the best solution. There are Commercial and Free options.

Zabbix, which has both free and commercial support, is a high-class open source distributed monitoring solution. Zabbix is a network management system application used to monitor and track the status of various network services, the server health and integrity, and other network hardware. It also allows support to configure e-mail alerts for an event which will help them to quickly react to any server problem. Zabbix has a very good graphic visualization and it plays an important role in monitoring a small batch or a multitude of servers.

In order to store data, Zabbix uses MySQL, PostgreSQL, SQLite or Oracle database engine. This article deals with the Installation and access mechanism of Zabbix.

As a pre-requisite, make sure that you have the following packages installed on your machine.

http, mysql, gcc, mysql-server, mysql-devel, net-snmp, net-snmp-utils, net-snmp-devel, net-snmp-libs, curl-devel, mak, ntp, php – with bcmath, gd and mysql support

You can use the Yum installer to install the above packages.
yum -y install package-name

Startup the time server for syncing the time between devices:
/etc/init.d/ntpd start

Download and Install fPing –

wget http://dag.wieers.com/rpm/packages/fping/fping-2.4-1.b2.2.el5.rf.i386.rpm

rpm -Uvh fping-2.4-1.b2.2.el5.rf.i386.rpm

chmod 7555 /usr/sbin/fping

Create Zabbix user –

useradd zabbix

Download Zabbix and Untar it –

wget http://jaist.dl.sourceforge.net/sourceforge/zabbix/zabbix-1.4.4.tar.gz

tar -xzvf zabbix-1.4.4.tar.gz

Grant zabbix database access to the corresponding user –

mysql -u root -p

mysql> CREATE DATABASE zabbix;


TO [email protected] IDENTIFIED BY ‘zabbixmysqlpass’;

Create the DB Schema –

cd zabbix-1.4.4

cat create/schema/mysql.sql | mysql -u zabbixmysqluser -pzabbixmysqlpass zabbix

cat create/data/data.sql | mysql -u zabbixmysqluser -pzabbixmysqlpass zabbix

cat create/data/images_mysql.sql | mysql -u zabbixmysqluser -pzabbixmysqlpass zabbix

Configuring Zabbix server –

./configure –enable-server –prefix=/usr/local/zabbix –with-mysql –with-net-snmp –with-libcurl

make install

make clean

Compile the Zabbix agent –

./configure –enable-agent –prefix=/usr/local/zabbix –enable-static

make install

Add Zabbix server and agent ports to /etc/services file – >

echo “zabbix_agent 10050/tcp” >> /etc/services

echo “zabbix_trap 10051/tcp” >> /etc/services

Copy sample .conf files to /etc/zabbix/ for server and agentd –

cd /etc/

mkdir zabbix

cp misc/conf/zabbix_agentd.conf /etc/zabbix

cp misc/conf/zabbix_server.conf /etc/zabbix

Modify the .conf files as per requirements. In/etc/zabbix/zabbix_server.conf file, change the following –





Changes in /etc/zabbix/zabbix_agentd.conf file –



cp misc/init.d/redhat/zabbix_agentd_ctl /etc/init.d/zabbix_agentd

cp misc/init.d/redhat/zabbix_server_ctl /etc/init.d/zabbix_server

Changes in /etc/init.d/zabbix_agentd and /etc/init.d/zabbix_serverfiles –


In the file /etc/init.d/zabbix_agentd, add the following on the top just after #!/bin/sh –

# chkconfig: 345 95 95

# description: Zabbix Agentd

In the file /etc/init.d/zabbix_server, add the following on the top just after #!/bin/sh –

# chkconfig: 345 95 95

# description: Zabbix Server

Configuring auto start and stop of services for different run levels –

chkconfig –level 345 zabbix_server on

chkconfig –level 345 zabbix_agentd on

chkconfig –level 345 httpd on

chkconfig –level 345 mysqld on

chkconfig –evel 0123456 iptables off

At the end of this step, please make sure that connections to ports 10050 and 10051 are allowed in the firewall settings. Re-check the firewall rules.

Copy the Zabbix front-end file(s) to the server’s DocumentRoot –

cp -r frontends/php /var/www/html/zabbix

Modify the /etc/php.ini file with the following –

max_execution_time = 300

date.timezone = Asia/Calcutta

Note: Remember to specify your time zone in the above setting. You can obtain the time zone name from http://us2.php.net/manual/en/timezones.america.php

Start Apache server for the changes to take effect –

 /etc/init.d/httpd start

How to execute the LICENSE –

chmod 777 /var/www/html/zabbix/conf

Access http://your-hostname/zabbix and simply follow the instructions.

While you run the steps, you will have to setup the/var/www/html/zabbix/php/conf/zabbix.conf.php file. A sample file would look like how it is shown below –




$DB_TYPE       = “MYSQL”;

$DB_SERVER     = “localhost”;

$DB_PORT       = “0″;

$DB_DATABASE   = “zabbix”;

$DB_USER       = “zabbixmysqluser”;

$DB_PASSWORD   = “zabbixmysqlpass”;



Once the installation is complete, execute the following steps –

chmod 755 /var/www/html/zabbix/conf

mv /var/www/html/zabbix/setup.php /var/www/html/zabbix/setup.php.bk

/etc/init.d/zabbix_agentd start

/etc/init.d/zabbix_server start

  1. Zabbix Monitoring System Access


Login into the Admin area using “admin” as user name. It does not require password at this point, and you can set the login password after you are inside the portal.

If http://your-hostname/zabbix/ does not show anything, it is possible that the php-pear module isn’t installed. In that case, you should consider installingphp-pear using the Yum installer.
yum -y install php-pear

You might also want to verify the error logs to spot the exact point of error.
