Which command can be used to stop the Zabbix server service?

The command that can be used to stop the Zabbix server service is "systemctl stop zabbix-server." This command is part of the systemctl utility, which is a command-line tool used to manage systemd services and the overall service management on Linux systems. When you execute this command, it sends a signal to the Zabbix server service to stop its operations gracefully.

Using systemctl is the recommended approach for managing services, as it provides a consistent interface across different distributions that use systemd. It allows users to start, stop, restart, and check the status of services with clear and concise commands. The "stop" directive is specifically designed to halt the specified service, which in this case is the Zabbix server.

Other options listed are not valid commands for stopping the Zabbix server service. For instance, using "systemctl halt zabbix-server" would not work as 'halt' is intended for shutting down the entire system rather than managing individual services. Similarly, "service zabbix-server kill" is not a correct usage, as the 'service' command does not include a 'kill' directive for stopping services. Lastly, "zabbix-server stop" does not follow the standard command syntax
