Chapter 4. Configuring the LVS Routers with Piranha Configuration Tool
The Piranha Configuration Tool provides a structured approach to creating the necessary configuration file for LVS —
/etc/sysconfig/ha/lvs.cf. This chapter describes the basic operation of the Piranha Configuration Tool and how to activate LVS once configuration is complete.
The configuration file for LVS follows strict formatting rules. Using the Piranha Configuration Tool is the best way to prevent syntax errors in the
lvs.cfand therefore prevent software failures.
4.1. Necessary Software
piranha-guiservice must be running on the primary LVS router to use the Piranha Configuration Tool. To configure LVS, you minimally need a text-only Web browser, such as
links. If you are accessing the LVS router from another machine, you also need an
sshconnection to the primary LVS router as the root user.
While configuring the primary LVS router it is a good idea to keep a concurrent
sshconnection in a terminal window. This connection provides a secure way to restart
pulseand other services, configure network packet filters, and monitor
/var/log/messagesduring trouble shooting.
The next four sections walk through each of the configuration pages of the Piranha Configuration Tool and give instructions on using it to set up LVS.
