How to solve the error the frontend does not match Zabbix database?

Question

MySQL

I'm trying to install Zabbix 4.0 on Debian 10, follow these instructions https://www.zabbix.com/ru/download?zabbix=4.0&os_d...
At the stage of installing the web interface (this is another page https://www.zabbix .com/documentation/4.0/en/manual... there was a problem, when trying to connect to the database, the error "the frontend does not match Zabbix database" appears.
Apparently, the problem is related to incorrect import of the initial database schema. At the stage, error 1118 occurs:

In general, the problem was solved as follows:
When creating the database, I did not specify the encoding, that is, in the place:
create database zabbix character set utf8 collate utf8_bin;
wrote:
create database zabbix;
Despite the fact that everything seems to be working, two questions arose:
1. What default encoding does MySQL use when creating a database?
2. Will there be problems with Zabbix due to the database created by such methods?

Answer 1

1) Can be checked with
SHOW CREATE DATABASE zabbix;
2) as far as I understand, there will be no problems
