Port-Forwarding With rinetd On Debian Etch

Thu, 04 Sep 2008 17:34:53 +0200

Port-Forwarding With rinetd On Debian Etch

This article shows how you can do port-forwarding with rinetd on Debian Etch. rinetd allows you to forward ports from one system to another. This useful if you have moved your web sites to a new server with a different IP address. Of course, you have modified your DNS records, but it can take a few days until DNS changes become effective, and that is where rinetd comes into play. If clients still use the old DNS records, rinetd can redirect them to the new server. With rinetd, you do not have to fiddle with iptables rules.

Integrating eAccelerator Into PHP5 And Lighttpd (Debian Etch)

Mon, 01 Sep 2008 17:54:51 +0200

Integrating eAccelerator Into PHP5 And Lighttpd (Debian Etch)

This guide explains how to integrate eAccelerator into PHP5 and lighttpd on a Debian Etch system. From the eAccelerator project page: "eAccelerator is a free open-source PHP accelerator, optimizer, and dynamic content cache. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times."

Automatic Cleaning Of Trash And/Or Junk Folders With ISPConfig (With Roundcube + Tmpreaper (Tmpwatch))

Automatic Cleaning Of Trash And/Or Junk Folders With ISPConfig (With Roundcube + Tmpreaper (Tmpwatch))

This short mini-howto will help you set up automatic cleaning of Trash- and Junkfolders. Most (web)mail clients (can) automatically create these. A lot of people don't clean there maildirectories causing Junk and Trash folders to grow massively in size and with ISPConfig (not yet) being able to set good maildirectory size limits the alternative is to have these folders cleaned after several days.

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch

Thu, 21 Aug 2008 18:38:18 +0200

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-peruser On Debian Etch

This article explains how you can install and configure apache2-mpm-peruser on a Debian Etch server. apache2-mpm-peruser is an MPM (Multi-Processing Module) for the Apache 2 web server, very similar to apache2-mpm-itk, but faster (almost as fast as apache2-mpm-prefork). mpm-peruser allows you to run each of your vhosts under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. It is based on metuxmpm, a working implementation of the perchild MPM. The result is a sane and secure web server environment for your users, without kludges like PHP's safe_mode.

Creating Advanced MySQL-Based Virtual Hosts On Lighttpd (Debian Etch)

Sun, 17 Aug 2008 19:10:58 +0200

Creating Advanced MySQL-Based Virtual Hosts On Lighttpd (Debian Etch)

This guide explains how you can create advanced virtual hosts on a lighttpd web server on Debian Etch that are stored in a MySQL database. The method described here does not use the lighttpd mod_mysql_vhost module, and unlike mod_mysql_vhost (which allows you to store only the hostname and document root of a vhost in a database), this method allows to store individual configuration directives for each vhost in the MySQL database.

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-itk On Debian Etch

Running Vhosts Under Separate UIDs/GIDs With Apache2 mpm-itk On Debian Etch

This article explains how you can install and configure apache2-mpm-itk on a Debian Etch server. apache2-mpm-itk is an MPM (Multi-Processing Module) for the Apache 2 web server. mpm-itk allows you to run each of your vhost under a separate UID and GID - in short, the scripts and configuration files for one vhost no longer have to be readable for all the other vhosts. mpm-itk works with mod_php because mpm-itk is based on the traditional prefork MPM, which means it's non-threaded. This means you don't need to use suExec or suPHP anymore to run a website's PHP scripts as a separate user.

How To Remotely Install Debian Over A RH Based Distro

How To Remotely Install Debian Over A RH Based Distro

Ocassionally, servers need to be retasked for various reasons. It has always been a challenge when the server has a distribution other than what I need. I do not want to drive to the data center to swap CDs around, so I decided to see if there was a way to remotely install the machine. I found some notes by Erik Jacobsen and used them to come up with an up-to-date how-to.

How To Set Up WebDAV With Lighttpd On Debian Etch

Thu, 07 Aug 2008 19:37:16 +0200

How To Set Up WebDAV With Lighttpd On Debian Etch

This guide explains how to set up WebDAV with lighttpd on a Debian Etch server. WebDAV stands for Web-based Distributed Authoring and Versioning and is a set of extensions to the HTTP protocol that allow users to directly edit files on the lighttpd server so that they do not need to be downloaded/uploaded via FTP. Of course, WebDAV can also be used to upload and download files.

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

Tue, 05 Aug 2008 12:34:32 +0200

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

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'd have to configure them in the global section of lighttpd.conf, which means they'd be valid for all vhosts. Therefore, mod_mysql_vhost is ideal if your vhosts differ only in the domain and document root.

Embedding Python In Apache2 With mod_python (Debian/Ubuntu, Fedora/CentOS, Mandriva, OpenSUSE)

Sun, 20 Jul 2008 18:46:34 +0200

Embedding Python In Apache2 With mod_python (Debian/Ubuntu, Fedora/CentOS, Mandriva, OpenSUSE)

This tutorial shows how to install and use mod_python on various distributions (Debian/Ubuntu, Fedora/CentOS, Mandriva, OpenSUSE) with Apache2. mod_python is an Apache module that embeds the Python interpreter within the server. It allows you to write web-based applications in Python that will run many times faster than traditional CGI and will have access to advanced features such as ability to retain database connections and other data between hits and access to Apache internals.
