a. Log in to the log host as a root user.

b. Create a subdirectory named LB in directory /var/log/, and then create file info.log in the LB

directory to save logs from the LB.

# mkdir /var/log/LB

# touch /var/log/LB/info.log

c. Edit the file syslog.conf in directory /etc/ and add the following contents.

# LB configuration messages

local4.info /var/log/LB/info.log

In this configuration, local4 is the name of the logging facility that the log host uses to receive

logs. info is the informational level. The UNIX system records the log information that has a

severity level of at least informational to the file /var/log/LB/info.log.

NOTE:

Be aware of the following issues while editing file /etc/syslog.conf:

• Comments must be on a separate line and must begin with a pound sign (#).

• No redundant spaces are allowed after the file name.

• The logging facility name and the information level specified in the /etc/syslog.conf file must be

identical to those configured on the LB by using the info-center loghost and info-center source

commands. Otherwise the log information might not be output properly to the log host.

d. Display the process ID of syslogd, kill the syslogd process, and then restart syslogd using the –r

option to make the new configuration take effect.

# ps -ae | grep syslogd

147

# kill -HUP 147

# syslogd -r &

Now, the system can record log information into the log file.

host at 1.2.0.1/16.

Configuration procedure

Before the configuration, make sure the LB and the log host can reach each other. (Details not shown.)

1. Configure the LB:

# Enable the information center.
