After configuring the appropriate network packet filters for
your situation, save the settings so they get restored after a
reboot. For iptables, type the following
command:
/sbin/service iptables save
|
This saves the settings in /etc/sysconfig/iptables so they can be recalled at
boot time.
Once this file is written, you are able to use the /sbin/service command to start, stop, and check the
status (using the status switch) of iptables. The /sbin/service
will automatically load the appropriate module for you. For an
example of how to use the /sbin/service
command, see Section 8.3
Starting the Piranha Configuration
Tool Service.
Finally, you need to be sure the appropriate service is set to
activate on the proper runlevels. For more on this, see Section 8.1 Configuring
Services on the LVS Routers.
The next chapter explains how to use the Piranha Configuration Tool to configure the LVS
router and describe the steps necessary to active an LVS
cluster.
