i had a tough time to configure nginx on my debian production environment.
the recent stable release from nginx is 0.6.x but on debian repository it was 0.4.x, so i had to build it from the source and install it.
since i had an old 0.4.x instance of nginx, installation wasn’t as smooth as i was expecting. here i would try to show how i have resolved those broken issues and made my way to run nginx to reverse proxy my backend mongrel instances.
i took several attemtps to remove the existing 0.4.x instance of nginx but i failed.
i used “aptitude remove nginx” i ended with the following error -
Reading package lists… Done
Building dependency tree
Reading state information… Done
The following packages will be REMOVED:

though this is not my real error code but it has similarity, i took it from the following url -
http://sudhanshuraheja.com/2007/09/remove-nginx-from-ubuntu-fiesty-fawn.html
this blog author had some suggestion, but that wasn’t working for me, so i tried in different way -
i executed “sudo apt-get build-dep nginx” i found this tips from one of the blog comments
the comment author explained in this way -
“this should install everything required to build the package (compiler, headers/libs, packaging tools). Usually on a fresh install I do this to get everything required to build zope.Then issue “apt-get source nginx” (you need deb-src sources in /etc/apt/sources.list). This will download nginx sources (original tarball, diff, and uncompressed sources with patches applied). Just cd in source dir, make your modifications and use “dpkg-buildpackage -rfakeroot -b” (this requires fakeroot package). In parent directory you should get new deb files ready to install, with start/stops scripts and your patches. Just take care of package update that will surely remove your nginx version.”
if you want service script to initiate nginx on startup follow the link -
