Installing A Web, Email, MySQL DB Cluster (Mirror) On Debian 5 With ISPConfig 3

Post date: August 11, 2010, 23:08 Category: Installing Views: 3515 Comments
Tutorial quote: This tutorial describes the installation of a clustered web, email, database and DNS server to be used for redundancy, high availability and load balancing on Debian 5 with the ISPConfig 3 control panel. GlusterFS will be used to mirror the data between the servers and ISPConfig for mirroring the configuration files. I will use a setup of two servers here for demonstration purposes but the setup can scale to a higher number of servers with only minor modifications in the GlusterFS configuration files.

Hardening Linux: a 10 step approach to a secure server

Post date: June 22, 2005, 10:06 Category: Security Views: 3485 Comments
Tutorial quote: The Internet has become a far more dangerous place than it was 20 years ago. Nowadays, Operating System and application security is an integral part of a server configuration and, while firewalls are very important, they are not the panacea.

This list of steps is intended as a guideline with a practical approach. We’ll try to provide a complete picture without getting into unnecesary details. This list won’t replace a good book on secure systems administration, but it will be useful as a quick guide.

Before we get started it’s worth to mention that security is not a status: it’s just a process. The correct initial setup of the server only provides a good start and helps you get half the way through. But you actually need to walk the other half of the road, by providing proper security vigilance, monitoring and updating.

Creating Simple Virtual Hosts With mod_mysql_vhost On Lighttpd (Debian Etch)

Post date: August 7, 2008, 09:08 Category: Installing Views: 2905 Comments
Tutorial quote: This guide explains how you can use mod_mysql_vhost to create simple virtual hosts on a lighttpd web server on Debian Etch. With mod_mysql_vhost, lighttpd can read the vhost configuration from a MySQL database. Currently, you can store the domain and the document root in the MySQL database which results in very simple virtual hosts. If you need more directives for your vhosts, you would have to configure them in the global section of lighttpd.conf, which means they would be valid for all vhosts. Therefore, mod_mysql_vhost is ideal if your vhosts differ only in the domain and document root.

The 'no-configuration, only-active-when-needed' SSH VPN

Post date: April 13, 2005, 03:04 Category: Network Views: 2673 Comments
Tutorial quote: So, we started thinking about how we might set up a VPN between the application server and our internal software mirror. The only requirement is that the VPN be initiated from the "inside-out" and that the connection is only active for as long as we need to use. In other words, it would only be active during an administration session. Ideally, it wouldn't be a lot of work to setup and tear down either.

SSH to the rescue...

Fortunately, SSH client and server come with support for this out of the box, requiring no additional software to be installed, and no configuration changes. On the server side, sshd, the setting "AllowTcpForwarding" defaults to "yes" unless your sshd_config file explicitly disables it. On the client side, all you have to do is request the forwarding.

Here, in one place, is complate instructions on how to find and navigate the common Linux documentation systems, including man, info, READMEs, HOWTOs, HTML, PDF/PS, DocBook, Gnome and KDE help system, and command-line option conventions. The guide I wish I'd had when I was new to Linux!

A Beginner's Guide To LVM

Post date: January 16, 2007, 19:01 Category: System Views: 3844 Comments
Tutorial quote: This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast.
