Zabbix Server 5.2 installation

[Amiram]

Hey,

I'm trying to install the Zabbix Server 5.2 from scratch on Ubuntu 18.04 version with mysql DB and nginx as a webserver.

I have encounter two problems.

1. Unable to connect to the mysql database that just has been installed
   1. There is no such mysql service at all
2. Missing "/usr/share/doc/zabbix-server-mysql-VERSION/create.sql.gz" so I cant configure my database.
