login mysql with root

mysql -u root -p

now create database

CREATE DATABASE zabbix CHARACTER SET UTF8;

now create a user with permission

GRANT ALL PRIVILEGES on zabbix.* to user@localhost IDENTIFIED BY 'password';

FLUSH PRIVILEGES;

quite;

after creating DB and user we need to restore the default DB of zabbix to mysql.

We can found that on /usr/share/doc/zabbix-server-mysql-3.0.0 in this location or
