Fix for accident nginx remove

Fix for accident nginx remove

Problem

I accidentally removed nginx from my Linux Server (Debian Jessie). I did it after my experiments with phusion passenger. I made:

$ sudo rm -rf /etc/nginx
$ sudo rm  /etc/init.d/nginx

And yes, I know that I made a stupid thing :)

After installing nginx by

$ sudo apt-get install nginx


I was able to run it. Test run

$ sudo nginx -t

output:

nginx: [emerg] open() "/etc/nginx/nginx.conf" failed (2: No such file or directory)
nginx: configuration file /etc/nginx/nginx.conf test failed

Problem

I found little issue till Pillow installing (via pip for newly installed Python 3.5 to the almost clear RPi 2 (mod. B) running Raspbian):

ValueError: --enable-jpeg requested but jpeg not found, aborting. 

My Raspbian version (information retrieved by running $ uname --all):

Building Python 3.5 on Raspberry Pi 2 (Raspbian)

Building Python 3.5 on Raspberry Pi 2 (Raspbian)

1. Problem

Problem: we want use the latest version of Python to run Flask and other fun stuff on our RPi 2 (mod. B). But only old version of Python (3.2) supported by apt-get.

We need to build and install our own build of latest Python release! So, our target will be Python 3.5.

Also, you may want to know What’s New In Python 3.5

UPD! You can follow procedures for Python 3.6 installation by following Building Python 3.6 on Raspberry Pi 3 from sources (clean Debian)
