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.

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

With this howto I explain how to set up suPHP on a Debian based ISPConfig server with php4. Mainly, it is based on Falko's howto http://www.howtoforge.com/apache2_suphp_php4_php5. Within the forums on Howtoforge, lots of information about "setting up suphp" can be found. However, this information is spread all over the forums, so it is not very clear how to set up suphp on an ISPConfig server. It was the reason for me to write this howto. When you've setup suPHP on your ISPConfig server, you are able to run the PHP scripts under the admin user of the website instead of www-data.
