Setting Up A Subversion Repository Using Apache, With Auto Updatable Working Copy

Setting Up A Subversion Repository Using Apache, With Auto Updatable Working Copy

Subversion is a free/open-source version control system. That is, Subversion manages files and directories over time. A tree of files is placed into a central repository. The repository is much like an ordinary file server, except that it remembers every change ever made to your files and directories. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of “time machine”.

Splitting Apache Logs With vlogger

Splitting Apache Logs With vlogger

Vlogger is a little tool with which you can write Apache logs broken down by virtual hosts and days. With vlogger, we need to put just one CustomLog directive into our global Apache configuration, and it will write access logs for each virtual host and day. Therefore, you do not have to split Apache's overall access log into access logs for each virtual host each day, and you do not have to configure Apache to write one access log per virtual host (which could make you run out of file descriptors very fast).

Introducing Remo - An Easy Way to Secure an Insecure Online Application with ModSecurity

Introducing Remo - An Easy Way to Secure an Insecure Online Application with ModSecurity

Say you have a nasty application on your Apache webserver that has been installed by some jerks from the marketing department and you can neither remove nor patch it. Maybe it is a time problem, a lack of know-how, a lack of source-code, or possibly even political reasons. Consequently you need to protect it without touching it. There is ModSecurity, but they say this is only for experts. A straightforward alternative is Remo, a graphical rule editor for ModSecurity that comes with a whitelist approach. It has all you need to lock down the application.

Apache: Creating A Session-Aware Loadbalancer Using mod_proxy_balancer (Debian Etch)

Apache: Creating A Session-Aware Loadbalancer Using mod_proxy_balancer (Debian Etch)

Since Apache 2.1, a new module called mod_proxy_balancer is available which lets you turn a system that has Apache installed into a loadbalancer. This loadbalancer retrieves requested pages from two or more backend webservers and delivers them to the user's computer. Users get the impression that they deal with just one server (the loadbalancer) when in fact there are multiple systems behind the loadbalancer that process the users' requests. By using a loadbalancer, you can lower the load average on your webservers. One important feature of mod_proxy_balancer is that it can keep track of sessions which means that a single user always deals with the same backend webserver. Most websites are database-driven nowadays with user logins etc., and you'd get weird results if a user logs in on one backend webserver, and then his next request goes to another backend webserver, meaning he'd get logged out again. You can avoid this by using mod_proxy_balancer's session-awareness.

Using Ruby On Rails With Apache2 On Debian Etch

Using Ruby On Rails With Apache2 On Debian Etch

This article shows how you can install Ruby on Rails (RoR) and integrate it in Apache2 on a Debian Etch system (including a short section at the end showing how to use RoR in a web site created with ISPConfig). Ruby on Rails is a web application framework which is rapidly gaining popularity among web programmers. It aims to increase the speed and ease with which database-driven web sites can be created and offers skeleton code frameworks (scaffolding) from the outset. Applications using the RoR framework are developed using the Model-View-Controller design pattern.

Running ISPConfig On Port 80 Using Apache's Reverse Proxy Feature (Debian Etch)

Running ISPConfig On Port 80 Using Apache's Reverse Proxy Feature (Debian Etch)

This article shows how you can configure a Debian Etch system that has the webhosting control panel ISPConfig installed so that ISPConfig can be accessed on port 80. By default ISPConfig uses port 81 which is a non-standard port and is blocked by some firewalls and ISPs. By using Apache's mod_proxy module, we can avoid this problem. It lets us create a reverse proxy that can fetch the pages from ISPConfig on port 81.

Secure Websites Using SSL And Certificates

Secure Websites Using SSL And Certificates

This how-to will guide you through the entire process of setting up a secure website using SSL and digital certificates. This guide assumes that you have already a fully functional (and configured) server running Apache, BIND, and OpenSSL. Just as a side note, this guide was written based on a Fedora Core 6 distribution, but should be the same for most other distros out there.

How To Set Up suPHP On A Debian Etch Based ISPConfig Server

How To Set Up suPHP On A Debian Etch Based ISPConfig Server

When you've set up suPHP on your ISPConfig server, you are able to run the PHP scripts under the admin user of the website instead of www-data. In general, this howto is the same as my howto "How To Set Up suPHP On A Debian Sarge Based ISPConfig Server" at http://www.howtoforge.com/suphp_debian_ispconfig but it contains some small but important modifications for Debian Etch.

Speed Up Google Analytics

Speed Up Google Analytics

This method uses crontab to execute a shell script that downloads an updated urchin.js file every 24 hours and saves it into your local sites directory. Thats it! The problem occurs when google-analytics.com/urchin.js is requested by billions of web users all over the world at one time, it can cause your sites pages to load at a snails pace. Especially if you are using WordPress or a similar CMS.
