Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Keepalived On Debian Etch
This article explains how to set up a two-node load balancer in an active/passive configuration with HAProxy
and keepalived on Debian Etch. The load balancer sits between the user
and two (or more) backend Apache web servers that hold the same
content. Not only does the load balancer distribute the requests to the
two backend Apache servers, it also checks the health of the backend
servers. If one of them is down, all requests will automatically be
redirected to the remaining backend server. In addition to that, the
two load balancer nodes monitor each other using keepalived, and if the
master fails, the slave becomes the master, which means the users will
not notice any disruption of the service. HAProxy is session-aware,
which means you can use it with any web application that makes use of
sessions (such as forums, shopping carts, etc.).

Setting Up Master-Master Replication With MySQL 5 On Debian Etch

Setting Up Master-Master Replication With MySQL 5 On Debian Etch
Since version 5, MySQL comes with built-in support for master-master
replication, solving the problem that can happen with self-generated
keys. In former MySQL versions, the problem with master-master
replication was that conflicts arose immediately if node A and node B
both inserted an auto-incrementing key on the same table. The
advantages of master-master replication over the traditional
master-slave replication are that you don’t have to modify your
applications to make write accesses only to the master, and that it is
easier to provide high-availability because if the master fails, you
still have the other master.

PHP Access To An MSSQL Database From Debian Etch With ODBC And FreeTDS
This assumes you already have Apache2 and PHP5 set up properly on
your system. My efforts to get this connection working were compiled
from information found at www.unixodbc.org and www.freetds.org.
These steps worked for me with an Apache2 web server with php5 running
on Debian Etch stable in October of 2007. The SQL server is running
Microsoft SQL 2005 on a Windows 2003 Server OS.

Using ATA Over Ethernet On Debian Etch
Imagine you have a machine with all of its disk full and another
with unused gigabytes, and you don’t want to move the data from one to
the other. Why not using
the second’s disk on the first, you can do it with iSCSI but you can do
it with
ATA over
Ethernet (AoE) too. It’s the second method I’ll explain in this
article. All of this was made with two computers running Debian Etch.
