I am looking to install the HttpGeoipModule for NGINX but learning I have to recompile the entire thing from source in order to do so. I have a new Media Temple DV 4.0 server and that comes with nginx v 1.3.0 stock and have never had to recompile from source before and a bit nervous to make changes without being able to revert to a previous state in the event something messes up (that and the fact it is affecting a live server so no idea what downtime is).
My plan was to copy all the existing modules used (nginx -V to list them all and copy the modules already compiled). Then rebuild from source with the copied info above and including the ./configure --with-http_geoip_module reference.
Is is possible to backup the existing nginx configuration in the event something goes wrong?
