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 
# yum install php php-cli php-common php-devel php-pear php-gd php-mbstring php-mysql php-xml 

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

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/3.0/rhel/7/x86_64/zabbix-release-3.0-1.el7.noarch.rpm

CentOS/RHEL 6: 
# rpm -Uvh http://repo.zabbix.com/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm

CentOS/RHEL 5: 
# rpm -Uvh http://repo.zabbix.com/zabbix/3.0/rhel/5/x86_64/zabbix-release-3.0-1.el5.noarch.rpm 

Step 3 – Install Zabbix Server with MySQL

# 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 5 – 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 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-<version>/create/ directory.

# cd /usr/share/doc/zabbix-server-mysql-3.0.0/create 

# mysql -u zabbix -p zabbixdb < schema.sql 
# mysql -u zabbix -p zabbixdb < images.sql 
# mysql -u zabbix -p zabbixdb < data.sql
