List demigods:
I'm building/reconfiguring an IBM Intellistation M Pro as a Linux Virtual Server to sit in front of several webservers.
Originally, I considered building out a load balancing reverse proxy with Apache, but have since learned of LVS (Linux Virtual Server). Contrary to the subject line I do know what LVS is; what I'm trying to sort out Red Hat's offering, Piranha.
Is Piranha Red Hat's LVS implementation? Is it built into the stock distribution of RHL 8 or RHL 9? Or is it a service/product purchase? Or a kernal patch? The RHL website is vague as to how to enable Piranha.
I would consider building out and custom configuring the kernal via the information at www.linuxvirtualserver.org, but the RHL path intrigues me greatly if it's built into the distro.
I understand the concepts of LVS fairly well, some of the deeper pieces are foggy, but I'm coming up to speed fairly quickly. This LVS is a major Linux piece in an otherwise Windoze dominated shop. I have installed the ServeRAID adapter and drives (RAID 5), an additional NIC and have outlined the rest of the install of the OS, but have still questions about the RHL LVS solution Piranha before I can continue.
Any help on answering this question is greatly appreciated.
Yours in Linux, Tim
Bwhaahhhahahahah. Sorry, trying poorly to do my best demi-god imitation.
Anyway, there is a list [EMAIL PROTECTED] that deals with piranha.
Be advised that Red Hat may not be supporting it as they are moving to
their new cluster manager on their Red Hat Advanced Server. It does
indeed handle load balancing, but if you want failover, you will need
the patched piranha by Sebastien Bonnet in order to handle scripts in
failover testing. (Scripts are available under lvs). I had submitted the
patches to Red Hat, but have not heard anything from their people, so I
guess for them it is a dead horse. Its really too bad since it is a
simple program that works well. Ed Croft, RHCE

Thanks Ed for the information. I'll subscribe to Piranha-List and sort through the archives (assuming the archives are on MARC). Seeing your notes on RH's AS/ES and clustering product paths, I think that I may return to the more technical route and build out a custom kernel. I just clicked on the Ultra Monkey link on the lvs.org site. UM looks promising and the documentation is good. It seems to plug neatly into RH8, which I have conveniently on hand on CD-ROM.
In the future, I would like to be buying RH products. This server is more than a proof of concept in a Windoze dominated shop. Yet at the same time the budget of this project is strained, in some ways crippled by MCSEs and FUD, so keeping costs down and investing the sweat equity into the configuration is paramount (700 for ES just would raise arguments that "for 700 dollars we could just install W2K." Of course to enable the load balancing requires proprietary software and the costs ballon beyond just the OS; but my colleagues would conveniently forget that in the argument to the higher ups). The project is a production demonstration of Linux in the enterprise, and possibly a beachhead for more, especially as a transistional platform for legacy mainframe applications and personnel.
Yours in Linux, with thanks, Tim
