What command is used to install MySQL on a Zabbix server?

The command used to install MySQL on a Zabbix server, particularly on systems that utilize a modern package manager like DNF, is indeed a version of the command that reflects the specific MySQL version repository. In this case, using "dnf -y install mysql-community-server" indicates that it targets the MySQL community server package directly, which is generally the recommended version for production installations. This package comes from the MySQL community repository and denotes a more controlled and specific installation process on systems like those running CentOS or Fedora.

Systems that use apt-get, as suggested in the first option, are usually Debian-based (like Ubuntu) where the package structure and naming might differ. Similarly, the yum install mysql-server command is relevant for older versions of CentOS or Red Hat systems, but DNF is the successor to YUM and is used in more recent distributions.

Simply using "install mysql" lacks specificity and does not align with the commands conventions in the package management systems. The "dnf" command is more aligned with managing and tracking dependencies accurately, ensuring that the appropriate version of MySQL is installed for a server setup that would include Zabbix compatibility.
