Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Fedora 8
Author: o.meyer • Tags: fedora, high-availability • Comments: 5Setting Up A High-Availability Load Balancer (With Failover and Session Support) With HAProxy/Heartbeat On Fedora 8 This document describes how to set up a two-node load balancer in an active/passive configuration with HAProxy and heartbeat on Fedora 8. The load balancer acts between the user and two (or more) Apache web servers that hold the same content. The load balancer passes the requests to the web servers and it also checks their health. If one of them is down, all requests will automatically be redirected to the remaining web server(s). In addition to that, the two load balancer nodes monitor each other using heartbeat. If the master fails, the slave becomes the master - users won't notice any disruption of the service. HAProxy is session-aware - you can use it with any web application that makes use of sessions like forums, shopping carts, etc.

Author: o.meyer • Tags: desktop, fedora • Comments: 1Osmo Personal Organizer On Fedora 8 This document describes how to install and use Osmo on Fedora 8.

In its current state the organizer is quite convenient to use - for example, the user can perform nearly all operations using the keyboard. Also, a lot of parameters are configurable to meet the user's preferences. On the technical side, Osmo is GTK+ based tool which uses a plain XML database to store all personal data."

Master-Master Replication With MySQL 5 On Fedora 8
Author: o.meyer • Tags: fedora, high-availability, mysql • Comments: 3Master-Master Replication With MySQL 5 On Fedora 8 This document describes how to set up master-master replication with MySQL 5 on Fedora 8. 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.

Virtual Users And Domains With Postfix, Courier And MySQL (Fedora 8)

Tags: antivirus, fedora, postfix •
Comments: 4 Virtual Users And Domains With Postfix, Courier And MySQL (Fedora 8) This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.
