4. Centering log collecting

Make Syslog Input Listener on Syslog : listen port is UDP 10514

Enable listen to rsyslog by rsyslog.conf

#vi /etc/rsyslog.conf

enable to $ModLoad imudp and $UDPServerRun 514

Syslog messages will forward enable Like this

*.* @127.0.0.1:10514;RSYSLOG_SyslogProtocol23Format

Finally, firewall open udp 514 port

#firewall-cmd --permanent --zone=public --add-port=514/udp
#firewall-com --reload
