Followed a-z as per the official tutorial to install zabbix but getting error

[longskin]

This is the error that I'm getting.
"ERROR 1045 (28000): Access denied for user 'zabbix'@'localhost' (using password: YES)"

https://www.zabbix.com/download?zabbix=5.0&os_distribution=centos&os_version=7&components=server_frontend_agent&db=mysql&ws=apache

I'm following this documentation for centos 7, zabbix version 5.0 LTS as you can see in the link above.
But I'm getting the above mentioned error when setting up database.
I've entered correct password, I'm sure of that.

"ERROR 1045 (28000): Access denied for user 'zabbix'@'localhost' (using password: YES)"

Connect to your the MySQL/MariaDB database server as the database 'root' user and type:

SHOW GRANTS FOR 'zabbix'@'localhost';

You don't need to paste the results here (if you do, be sure you obfuscate the encrypted password), but just be certain that the results look correct.
