Ошибка юнита zabbix server service

I just installed Zabbix 5.0 LTS (The Latest verion of Zabbix) on RHEL-8 OS. On logging in the Zabbix front end, I gett a message saying «Zabbix server is not working». & bar below says:»Zabbix server not working.Information delayed may not be current».Kindly provide help?

Edit:My server port is 10051.

On entering «service zabbix start», I get output:

Redirecting to /bin/systemctl start zabbix.service
Failed to start zabbix.service:Unit zabbix.service not found.

& on entering «systemctl restart zabbix-server zabbix-agent httpd php-fpm», I get:

Job for zabbix-server.service failed because the control process exited with error code.
See "systemctl status zabbix-server.service" and "journalctl -xe" for details.

Output of «journalctl -xe»:

RHEL8 platform-python[5746]: SELinux is preventing zabbix_server from using the dac_override capability.

If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system
Then turn on full auditing to get path information about the offending file and generate the error again.

Turn on full auditing
#auditctl -w /etc/shadow -p w

#ausearch -m avc -ts recent

If you believe that zabbix_server should have the dac_override capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
#ausearch -c 'zabbix_server' --raw | audit2allow -M my-zabbixserver
#semodule -X 300 -i my-zabbixserver.pp
