Installation of previous/old versions of packages in Debian
Recently, I encountered a problem installing the previous version of php on Debian. (I'm using the testing branch, php came as 5.6.x, but I needed to roll back to 5.5.x). Let's see how we can install the previous version.
Setting up nginx + php-fpm on Debian/Ubuntu
Nginx is an HTTP server. Compared to apache, it is more resilient and capable of handling a larger number of connections. It is mainly used on production servers, although it is rarely configured for local development, even though it is no more difficult than configuring apache + php.
