I am installing Zabbix 3.4 on a set of secured Centos 7 systems behind a firewall with no internet access.

I am directly installing at the command line from the rpm files.

I have installed mysql from the rpm files and am able to get into mysql from the command line.

I have installed all the prerequisite php and other packages - leaving only zabbix-server-mysql to install.

As shown in the screenshot, zabbix-server-mysql fails wanting libmysqlclient.so.18 installed - which is a part of the mariadb-libs.

When I try to install the two together, I am told that mariadb-libs is obsoleted by the already installed mysql-community-libs .

So I am stuck - mariadb is both required and obsoleted at the same time.  How do I get around this given I only have the command line and rpm files at my disposal?
