Creating initial database

Create zabbix database and user on MySQL.

# mysql -uroot
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';
mysql> exit

Import initial schema and data.

# cd /usr/share/doc/zabbix-server-mysql-2.2.0/create
# mysql -uroot zabbix < schema.sql
# mysql -uroot zabbix < images.sql
# mysql -uroot zabbix < data.sql

Starting Zabbix server process

Edit database configuration in zabbix_server.conf

# vi /etc/zabbix/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix

Start Zabbix server process.

# service zabbix-server start

Editing PHP configuration for Zabbix frontend

Apache configuration file for Zabbix frontend is located in /etc/httpd/conf.d/zabbix.conf. Some PHP settings are already configured.

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 Europe/Riga

It's necessary to uncomment the “date.timezone” setting and set the right timezone for you. After changing the configuration file restart the apache web server.

# service httpd restart

# sestatus

# setenforce 0

To change selinux mode to permissive. (Otherwise it wont let you grab info from zabbix server).

Zabbix frontend is available at http://localhost/zabbix in the browser. Default username/password is Admin/zabbix.
