Step 1: Set Up 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 many skip this step if you have already configured it.
Install All Services
# yum install httpd httpd-devel 
# yum install mysql mysql-server

Start All Services
# service httpd start
# service mysqld start
MySQL Initial Setup
Run following command to setup mysql initially and secure it
# mysql_secure_installation

Step 2: Configure Yum Repository

Before installing Zabbix first configure zabbixzone rpm repository in our system using following commands.
CentOS/RHEL 7:
# rpm -Uvh http://repo.zabbix.com/zabbix/2.2/rhel/7/x86_64/zabbix-release-2.2-1.el7.noarch.rpm

CentOS/RHEL 6:
# rpm -Uvh http://repo.zabbix.com/zabbix/2.2/rhel/6/x86_64/zabbix-release-2.2-1.el6.noarch.rpm

CentOS/RHEL 5:
# rpm -Uvh http://repo.zabbix.com/zabbix/2.2/rhel/5/x86_64/zabbix-release-2.2-1.el5.noarch.rpm

Step 3: Install Zabbix Server with MySQL

Use following command to install Zabbix using mysql database support packages on your system.
# yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-java-gateway

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. More timezone’s
  php_value date.timezone Asia/Kolkata
After changing value restart Apache service.
# service httpd restart

Step 4: Create Zabbix MySQL Database

This installation is using mysql as backend of zabbix, So we need to create MySQL database and User for zabbix installation.
# mysql -u root -p

mysql> CREATE DATABASE zabbix CHARACTER SET UTF8;
mysql> GRANT ALL PRIVILEGES on zabbix.* to 'zabbix'@'localhost' IDENTIFIED BY 'SECRET_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.
# mysql -u zabbix -p zabbix < /usr/share/doc/zabbix-server-mysql-2.2.8/create/schema.sql
# mysql -u zabbix -p zabbix < /usr/share/doc/zabbix-server-mysql-2.2.8/create/images.sql
# mysql -u zabbix -p zabbix < /usr/share/doc/zabbix-server-mysql-2.2.8/create/data.sql
