Just completed moving this website https://toggen.com.au/blog to nginx web server.

The issues I found:

• Installing and configuring php-fpm to run per user
• Learning the syntax of the nginx conf files
• Rewriting the .htaccess files into the correct nginx rules
• Trying to figure out the order of precedence for the nginx location {} blocks
• Many nginx configuration examples use old syntax and you need to learn how to re-write them in try_files format
• Running multiple PHP applications such as CakePHP, WordPress and Gallery 3 which all have different ways of handling arguments.
• A lot of howto's assume that the application is in the web root moving them to sub-directories can be challenging when having to port the aforementioned .htaccess rules
• Installing on CentOS which has a different conf file layout to the more ubiquitous Debian based distro's
