Step 1 – SetUp Apache, MySQL and PHP

In order to use Zabbix, we required a Web Server, database server, and PHP to work. In this steps we are going to set up these services, You may skip this step if you have already configured it.

Install All Services

# yum install httpd httpd-devel
# yum install mysql mysql-server
# yum install php php-devel php-bcmath  php-pear php-gd php-mbstring php-mysql php-xml

Start All Services

# service httpd start
# service mysqld start

MySQL Initial Setup

Run the following command to setup MySQL initially and secure it

# mysql_secure_installation

Step 2 – Configure Yum Repository

You can file zabbix repositories package on zabbix official website.

You can also use one of following commands to add zabbix repository in your system.

CentOS/RHEL 7:

# rpm -Uvh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm

CentOS/RHEL 6:

# rpm -Uvh http://repo.zabbix.com/zabbix/3.4/rhel/6/x86_64/zabbix-release-3.4-1.el6.noarch.rpm

Step 3 – Install Zabbix Server with MySQL

You have added Zabbix yum repository in above step. Now use the following command to install Zabbix server with MySQL database support packages on your system.

# yum install zabbix-server-mysql zabbix-web-mysql zabbix-proxy-mysql

Step 4 – Setup Zabbix Apache Configuration

Zabbix creates its own apache configuration file /etc/httpd/conf.d/zabbix.conf. Edit this file and just update timezone.

# php_value date.timezone Asia/Kolkata

After changing value restart Apache service.

# service httpd restart

Step 5 – Configure MySQL Database for Zabbix

This installation is using MySQL as the backend of Zabbix, So we need to create MySQL database and User for Zabbix installation.

# mysql -u root -p

mysql> CREATE DATABASE zabbixdb CHARACTER SET UTF8;
mysql> GRANT ALL PRIVILEGES on zabbixdb.* to zabbix@localhost IDENTIFIED BY 'password';
mysql> FLUSH PRIVILEGES;
mysql> quit

After creating database restore the default mysql database provided by zabbix. These files can be found at /usr/share/doc/zabbix-server-mysql-/create/ directory.

# zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uroot -p zabbixdb
# zcat /usr/share/doc/zabbix-proxy-mysql*/schema.sql.gz | mysql -uroot -p zabbixdb

Now edit Zabbix server configuration file /etc/zabbix/zabbix_server.conf and update the following database configurations.

DBHost=localhost
DBName=zabbixdb
DBUser=zabbix
DBPassword=password

Step 6 – Start Zabbix Server

After completing setup, let’s start Zabbix server using the following command.

# service zabbix-server start

After starting Zabbix service, let’s go to Zabbix web installer and finish the installation.

Step 7 – Complete Zabbix Web Installer Wizzard

Zabbix web installer can be accessed on /zabbix subdirectory URL on your servers IP or domain. For example, host.tecadmin.net is pointed to my Zabbix server. Now access the Zabbix using the following URL. You must change FQDN as per your setup.
