firewall-cmd --permanent --add-port=10050/tcp --zone=public

firewall-cmd --reload

</code></pre>

h3. Troubleshoot

The agent failed to start ... see status

see also https://www.zabbix.com/forum/showthread.php?t=46796

tried to set PID to @PIDFile=/tmp/zabbix_agentd.pid@

</code></pre>

<pre>

vim /etc/zabbix/agentd.conf

vim /usr/lib/systemd/system/zabbix-agent.service

</pre>

<pre>

systemctl daemon-reload

systemctl start zabbix-agent

</pre>

didn't work either. 

double checked that @/run/zabbix/@ was existing and had right owner/rights

everything seemed to be ok.

After another restart and reset the PID back to @PIDFile=/run/zabbix/zabbix-agentd.pid@ and another daemon-reload everything worked out ok.
