How to install wordpress with apache, mod_proxy_fcgi and php-fpm on Ubuntu 16.04

Hi everyone,

In one of the previous posts we've discussed how to setup basic website to work with apache and php-fpm. And today I'd like to continue that topic and install wordpress to work with apache and php-fpm. Once you've got that basic website to work with php-fpm, there are not many differences from 'non-php-fpm' wordpress setup. Anyway, I am still going to describe it here in details.
