Installation guide
protocols or creating a multi-port virtual server for separate, but related protocols. In this
example, the above virtual server has a Firewall Mark of 80 because we are bundling
connections to HTTP on port 80 and to HTTPS on port 443 using the firewall mark value of 80.
When combined with persistence, this technique will ensure users accessing both insecure and
secure webpages are routed to the same real server, preserving state.
Warning
Entering a firewall mark in this field allows IPVS to recognize that packets bearing this
firewall mark are treated the same, but you must perform further configuration outside of
the Piranha Configurat ion Tool to actually assign the firewall marks. See Section 3.4,
âMulti-port Services and LVSâ for instructions on creating multi-port services and
Section 3.5, âConfiguring FT Pâ for creating a highly available FT P virtual server.
Device
Enter the name of the network device to which you want the floating IP address defined the
Virtual IP Address field to bind.
You should alias the public floating IP address to the Ethernet interface connected to the public
network. In this example, the public network is on the eth0 interface, so eth0:1 should be
entered as the device name.
Re-entry T ime
Enter an integer value which defines the length of time, in seconds, before the active LVS router
attempts to bring a real server back into the pool after a failure.
Service Tim eout
Enter an integer value which defines the length of time, in seconds, before a real server is
considered dead and removed from the pool.
Quiesce server
When the Quiesce server radio button is selected, anytime a new real server node comes
online, the least-connections table is reset to zero so the active LVS router routes requests as
if all the real servers were freshly added to the pool. This option prevents the a new server
from becoming bogged down with a high number of connections upon entering the pool.
Load m onitoring tool
The LVS router can monitor the load on the various real servers by using either rup or
ruptim e. If you select rup from the drop-down menu, each real server must run the rstatd
service. If you select ruptime, each real server must run the rwhod service.
