I'm trying to create a maridb table on a rhel instance in my ec2 container, but everytime I try to start mariadb I get this:

Redirecting to /bin/systemctl start mariadb-server.service Failed to start mariadb-server.service: Unit mariadb-server.service not found.

I've been searching for the answer to this for a day or two but no luck. I also ended coming across these modular dependency problems, but I honestly have no idea what any of this means. I'm still fairly new to learning Linux.

[root@ip-172-31-40-7 html]# yum list installed | grep mariadb Modular dependency problems:

Problem 1: conflicting requests - nothing provides module(perl:5.26) needed by module perl-DBD-MySQL:4.046:8010020190322121447:073fa5fe-0.x86_64 Problem 2: conflicting requests - nothing provides module(perl:5.26) needed by module perl-DBI:1.641:8010020190322130042:16b3ab4d-0.x86_64 mariadb.x86_64 3:10.3.17-1.module+el8.1.0+3974+90eded84 @rhel-8-appstream-rhui-rpms

I also tried to remove packages, clean and reinstall but didn't work.

I'm still actively trying to find a solution, any help would be greatly appreciated.

MariaDB is a drop-in replacement for MySQL, I am thinking that perl-DBD-MySQL could be tied to an installation of MySQL on your server. If you don't need it maybe you should remove it.

I removed mysql packages and ran the following : it instantly started!
