19.5. Setting Up a Host Logging Server
Hosts generate and update log files, recording their actions and problems. Collecting these log files centrally simplifies debugging.
This procedure should be used on your centralized log server. You could use a separate logging server, or use this procedure to enable host logging on the Red Hat Virtualization Manager.
Setting up a Host Logging Server
Configure SELinux to allow
rsyslogtraffic.# semanage port -a -t syslogd_port_t -p udp 514
Edit /etc/rsyslog.conf and add the following lines:
$template TmplAuth, "/var/log/%fromhost%/secure" $template TmplMsg, "/var/log/%fromhost%/messages" $RuleSet remote authpriv.* ?TmplAuth *.info,mail.none;authpriv.none,cron.none ?TmplMsg $RuleSet RSYSLOG_DefaultRuleset $InputUDPServerBindRuleset remote
Uncomment the following:
#$ModLoad imudp #$UDPServerRun 514
Restart the
rsyslogservice:# systemctl restart rsyslog.service
Your centralized log server is now configured to receive and store the messages and secure logs from your virtualization hosts.
