I'm hoping to chronicle this enough to be useful for someone else that would like to use this approach. Additions or corrections are greatly appreciated. Use the comment function to communicate with me. Background
I'm writing a web application for a manufacturing company to track and controll flow processes in real time. They have another developer writing an interface for bidding, invoicing and inventory control in a Microsoft product hooked to a MSSQL 2005 server. I'm writing my application in PHP on Zend Framework , running on an Apache web server. My PHP application will use the MSSQL 2005 database since that project was already mostly done. Typically I prefer MySQL because it's cheaper to develop on and it is an excellent product. To save the client money we decided to use LTSP on some old used computers so that they would be cheap and easy to trade out if they had problems. No user information will be retained so we're going with kiosk mode. |

Mandriva 2008 Failover Server - Part 2 DRBD, MySQL
I put this server in into production on March 29th of 2008 and it's been up ever since except for one time when the power went off longer than the batteries could hold up. This HOWTO is NOT a substitue for reading about each of the components that makes this work. In fact you will probably need to do that anyway to fill in any gaps that this system administrator might have left out just because I'm so familiar. DRBD is rather technical and MUST be brought up correctly after a crash or you can loose data.
The names and IP addresses have been randomized so you'll need to plug in what works for you. Hope this helps someone and I'm always glad for comments and corrections. I'm pretty busy so I'll finish posting these instructions as I'm able unless someone emails me that they'd like the rest soon than later. Use at your own risk. This server is not made to be directly on the Internet. |

Mandriva 2008 Failover Server - Part 1
Heartbeat+DRBD+LVM Part 1 covers the initial base system I put this server in into production on March 29th of 2008 and it's been up ever since except for one time when the power went off longer than the batteries could hold up. This HOWTO is NOT a substitue for reading about each of the components that makes this work.

OpenSource is something really big and I'm only scratching the surface in the things I'm discovering. Since my journey began back in 1998 it's been quite a wild ride. |

How do you get some cheap redundancy for those old IDE machines? They still make great firewalls, fileservers or Intranet servers although hardware is becoming so cheap that it may not be worth the effort except for the learning experience. Since my original posting of this (and since I am continually learning more and more) I started saving a little more room on the system by only putting 64Meg on md0 and only putting /boot on it since that is all that's need to get the system running. |
