Issues observed

• file permissions corrected with chmod 755 /var/run/zabbix
• incorrect hostname in /etc/zabbix/zabbix_agentd.conf
• timezone not configured in /etc/php.ini

Check out configuration

/etc/zabbix/zabbix_server.conf
/etc/php-fpm.d/zabbix.conf,
/etc/zabbix/zabbix_agentd.conf

Check out logs

tail /var/log/zabbix/zabbix_agentd.log
tail /var/log/zabbix/zabbix_server.log

If you get following error in zabbix_agentd.log then run command below …

Solution:

# grep AVC /var/log/audit/audit.log* | audit2allow -M systemd-allow; semodule -i systemd-allow.pp
IMPORTANT ***
To make this policy package active, execute:
semodule -i systemd-allow.pp
