2. The syslog-ng startup procedure, /etc/init.d/syslog-ng, relies on several

configuration variables. Edit /etc/sysconfig/syslog-ng as follows:

a. Change the CLOG_CONFIGURED line to:

CLOG_CONFIGURED=1

b. Add the following lines:

CLOG_CONSOLIDATOR=0

CLOG_CONS_IP=<IP address of the log consolidator>

c. If using the TCP protocol, add the following lines:

CLOG_TCP=1

CLOG_TCP_PORT=<log consolidation server tcp port>

If using ssh port forwarding, add:

CLOG_SSH=1

CLOG_SSH_PORT=<ssh port chosen>

otherwise, add:

CLOG_SSH=0

otherwise, if using the UDP protocol, add:

CLOG_TCP=0

If consolidating the local syslogs, add:

CLOG_SYSLOG=1

otherwise add:

CLOG_SYSLOG=0

If consolidating this cluster’s package logs, add:

CLOG_PACKAGE=1

otherwise, add:

CLOG_PACKAGE=0

3. All the files edited thus far need to be distributed clusterwide:

# ccp /etc/syslog-ng.conf.client /etc/

# ccp /etc/sysconfig/syslog-ng /etc/sysconfig/

on Red Hat or

# ccp /etc/syslog-ng/syslog-ng.conf.client /etc/

# ccp /etc/sysconfig/syslog-ng /etc/sysconfig/

on SLES.

Create the following symbolic link on each cluster member:

# ln -sf /etc/syslog-ng.conf.client /etc/syslog-ng.conf

on Red Hat or

# ln -sf /etc/syslog-ng/syslog-ng.conf.client /etc/syslog-ng.conf

on SLES.

4. When using TCP with ssh port forwarding, record the ssh port number you chose above

in the /etc/services file. For example, add the line:

clog_ssh 1776/tcp # Consolidated logging with ssh port forwarding

Add this line to the /etc/services file of each cluster member.

5. To consolidate this cluster’s package logs, additional manual steps are needed on the log

consolidation server. Each time a package is created or deleted on this cluster, these steps

need to be done. Refer to “Consolidating Package Logs on the Log Consolidation Server”

(page 76).
