3.6. Saving Network Packet Filter Settings
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/iptablesso they can be recalled at boot time.
Once this file is written, you are able to use the
/sbin/servicecommand to start, stop, and check the status (using the status switch) of
/sbin/servicewill automatically load the appropriate module for you. For an example of how to use the
/sbin/servicecommand, see 節 2.3, “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 節 2.1, “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 activate LVS.
