Here’s how to install the OpenStreetMap Nominatim service on your own server. It can be used to geocode and reverse geocode addresses and map coordinates. You will also get a web interface which loads map tiles from openstreetmap.org while doing geocoding requests using your own server. Continue reading OpenStreetMap Nominatim Server for Geocoding
There seems to be a patch lying around to enable phpass authentication in mod_auth_mysql. Its inclusion in mod_auth_mysql has been requested a long time ago, and again more recently, but for one reason or another it has been declined. Inclusion of the patch into the Debian package has also been requested.
Thanks to Peter Lamberg, there are good instructions around on how to apply the patch and enable it. I’ve made available a pre-compiled 64-bit package here: Continue reading Apache HTTP authentication against WordPress password database
In part I, we learned how to configure Apache to server any .py file as a web application using mod_wsgi. I promised to tell you more about WebOb and multiprocessing and multithreading, and exception handling. I’ll save those topics for later articles. Instead, in this part I will talk about using mod_rewrite – if, why and how to get rid of the .py extension. You will need the test apps from part I to try these out.

I admit it, I’m a long-time PHP programmer. I got stuck with it for a long time with all my web-based stuff, simply because it is so easy to set up. Well, there is no set-up, it just works. You just add pages to your web server root and give a .php extension to them, and they get requests and give back responses. Nice and simple.
I still use PHP for quick and dirty things (like running shell commands through web interfaces – yes, really, really naughty…) For doing more complex work, I prefer Python. But I miss the PHP-like way of just adding pages or “web applications” with zero-setup. I will examine the possibilities in Python for this kind of behaviour in this article.
Please remember, there are many, some say even too many, Python web frameworks available already that handle all this stuff for you “automagically”. You are almost certainly better off with using one of them, if you want to get work done. But they all require some kind of setup work.
Then there’s the thing with all kinds of frameworks, that instead of you calling some library, the behaviour of which you understand, to do your work, a framework calls your code. That is all right when things work as expected. But whenever there are glitches, you need to start digging around the framework code to see exactly what’s wrong. And if it is a big framework, that could mean a lot of digging around. For that reason, if you’re a reasonably seasoned programmer, I think it might not be half bad an idea to create your own minimalistic framework, using existing, good quality libraries the behaviour of which you understand, and which you can easily poke in the Python shell if you think something’s not working like it should. Or just to see what’s available, and try out the available code.
Also, knowing how stuff works never hurts. This article is also about learning how the Apache http requests are dispatched to Python code through mod_wsgi. I insist on knowing how things work, so I’m doing it the hard way. Continue reading Serving Python scripts with Apache mod_wsgi, part I
Here’s how to install and configure AWStats to compile separate statistics about multiple Apache sites or virtual hosts running on a single server. This can be done when you configure each Apache site or virtual host to use a different access log file.
The following instructions have been tested on Ubuntu 12.04.
I was not able to compile PHP 5.2.6 with IBM HTTP Server 6.1 as a module, so I compiled it as a CGI binary instead. Here’s how to do it. Continue reading Installing PHP 5 on AIX using IBM HTTP Server
First, create a user account for your Apache in the Active Directory. Let’s assume the AD Kerberos realm is KOO.FI, and the user name we have created is “apache”. Also create a computer account, let’s call that “apachesrv”.
To communicate securely using SSL (also known as TLS or Transport Layer Security), web servers need a key pair of public and private keys. This key pair can be generated and signed by yourself, but to prevent the web browser from asking “stupid” questions about the validity of a certificate, you must pay a company, called a Certificate authority, such as Verisign, Geotrust, or Thawte, for the added simplicity. That company will then verify that you are who you are (in theory, at least) and then sign your public key with their certificate. Their certificate is already bundled with most browsers and thus trusted by default, which also makes your newly signed certificate trusted as well.
