98 Chapter 8. Initial LVS Configuration
If you are clustering multi-port services or using firewall marks, you must also enable the
iptables
service.
It is best to set these services to activate in both runlevel 3 and runlevel 5. To accomplish
this using
chkconfig
, type the following command for each service:
/sbin/chkconfig --level 35
daemon
on
In the above command, replace
daemon
with the name of the service you are activating.
To get a list of services on the system as well as what runlevel they are set to activate on,
issue the following command:
/sbin/chkconfig --list
Warning
Turning any of the above services on using
chkconfig
does not actually start the dae-
mon. To do this use the
/sbin/service
command. See Section 8.3 Starting the Piranha
Configuration Tool Service
for an example of how to use the
/sbin/service
command.
For more information on runlevels and configuring services with
ntsysv
and the
Services
Configuration Tool
, refer to the chapter titled "Controlling Access to Services" in the Red
Hat Enterprise Linux System Administration Guide .
8.2. Setting a Password for the Piranha Configuration Tool
Before using the
Piranha Configuration Tool
for the first time on the primary LVS router,
you must restrict access to it by creating a password. To do this, login as root and issue the
following command:
/usr/sbin/piranha-passwd
After entering this command, create the administrative password when prompted.
Warning
For a password to be more secure, it should not contain proper nouns, commonly used
acronyms, or words in a dictionary from any language. Do not leave the password unen-
crypted anywhere on the system.
