Building a reverse proxy server with Nginx, Certbot, Raspbian Stretch Lite and Raspberry Pi 3

The Nginx reverse proxy server runs well on Raspberry Pi 3 and you can use it behind a router to route HTTP traffic to upstream web applications.

A Raspberry Pi 3 reverse proxy server is a very useful appliance to help us host multiple websites from home.

Some examples of web applications that you may want to host at home includes:

This post discusses how you can build a reverse proxy server with nginx, Certbot, Raspbian Stretch Lite and Raspberry Pi 3 to proxy HTTP traffic directed at applications on your home network.

Installing Certbot on Raspbian Stretch Lite for obtaining Let’s Encrypt’s browser-trusted certificates

By offering free browser-trusted certificates, Let’s Encrypt makes it easy for ordinary folks like you and me to deploy secure web applications that serve HTTPS traffic 24-7.

The issuance of Let’s Encrypt certificates is automated by software participating in the ACME protocol. We will need to run such a software on devices which host web servers serving HTTPS traffic.

The Raspbian Stretch Lite operating system is a way to create performant web-based appliances with Raspberry Pis. If you need to secure your web-based applications on Raspbian Stretch Lite, you may choose to install Certbot on Raspbian Stretch Lite as a first step.

This post extends Certbot’s installation instruction on Debian Stretch to provide the steps for installing Certbot on Raspbian Stretch Lite.

How to setup Raspbian Stretch Lite on Raspberry Pi 3 to run Python 3 applications

Raspbian Stretch Lite operating system is the Raspberry Pi Foundation’s official supported operating system for running headless software. It is a good operating system for different Raspberry Pi 3 use cases. Some examples include:

If you are planning to use Raspberry Pi 3 GPIO to interface with the real world, it is recommended that you setup Raspbian Stretch Lite to run Python 3 applications.

This post provides the steps to setup Raspbian Stretch Lite on Raspberry Pi 3 for running Python 3 applications.

Setting up a fast git server on Raspberry Pi Zero W with Go Git Service (Gogs) and Raspbian Stretch Lite

The Go Programming Language is a compiled programming language created by Robert Griesemer, Rob Pike, and Ken Thompson from Google in 2009. With Google Go, it is possible to build programs that run efficiently on minimum hardware resources. The compiled code runs close to the speed of C. Use cases of Go Programming language includes Docker, Kubernetes and Go Git Service.

If you happen to need a self-hosted git server to track software projects that you build on the side, you can consider using Go Git Service. With the Raspberry Pi Zero W bundle set, you can set up a fast git server that does not take up too much space on your desk.

This post details how you can setup a fast git server on Raspberry Pi Zero W with Go Git Service and Raspbian Stretch Lite.

How to setup Raspbian Stretch Lite with remote configuration over WiFi on first boot

Two of the good features of Raspbian Stretch Lite is that it allows us to enable the SSH server and connect to our WiFi network before it boots up for the first time.

Combining these two features is useful for projects based on Raspberry Pi Zero W as we can configure Raspbian Stretch Lite via SSH without connecting extra peripherals to it.

This post documents how you can enable remote configuration of your Raspbian Stretch Lite over WiFi on first boot.

How I setup a Raspberry Pi Zero W CCTV camera with motionEye and Raspbian Stretch Lite

I had previously built a Raspberry Pi Zero W CCTV camera with motionEyeOS which was connected to the Wifi network of my old DLink router.

After I started using Linksys AC1900 Dual Band Wireless Router as my home router, I could no longer connect to that Raspberry Pi Zero W CCTV camera.

After reinstalling motionEyeOS a couple of times on my Raspberry Pi Zero W, I determined that motionEyeOS is not suitable for this new Wifi network.

On the other hand, my setup of WordPress on Raspberry Pi Zero W with Raspbian Stretch Lite, nginx, mariadb and PHP was able to connect to my new Wifi network, even after multiple system reboots.

Hence, I figured that if I wanted to build a Raspberry Pi Zero W CCTV camera that can connect to my new Wifi network, I could use Raspbian Stretch Lite as the base operating system and install motionEye for the web frontend to view the camera footage.

This post documents how I setup a Raspberry Pi Zero W CCTV with motionEye and Raspbian Stretch Lite.

How I setup Jenkins on my Raspberry Pi 3 with Raspbian Stretch Lite

Jenkins is a renowned open source automation server that can help offload programmers from performing repetitive tasks like:

  • running unit tests to make sure new code does not break existing codes.
  • compiling and packaging the binaries from codes and dependencies.
  • deploying new binaries to testing servers.
  • checking whether production server is up and running.
  • and etc.

If you have a Raspberry Pi 3 and you want to automate some of the tasks for your side projects, you may want to consider setting up Jenkins on your Raspberry Pi 3 with Raspbian Stretch Lite as the operating system.

This post documents how I setup Jenkins on my Raspberry Pi 3 with Raspbian Stretch Lite.

Setting up WordPress on Raspberry Pi Zero W with Raspbian Stretch Lite, Nginx, MariaDB and PHP as the LEMP stack

A Raspberry Pi Zero W is a small and capable computer that included a Wi-Fi chip for projects that requires an Internet connection.

Apart from running client programs on the Raspberry Pi Zero W, it is equally capable of being a web server. Since I had a spare Raspberry Pi Zero W lying around the house and there are good reasons to blog as a programmer, I decided to use it as a WordPress server to collect content for a new blog project.

This post documents how I setup WordPress on a Raspberry Pi Zero W with Raspbian Stretch Lite, nginx, MariaDB and PHP as the LEMP stack.

How to setup Raspbian Stretch Lite on Raspberry Pi Zero W to run Python 3 applications

With Wi-Fi included, the Raspberry Pi Zero W is very useful for implementing embedded projects that require Internet connection.

Apart from using the Raspberry Pi Zero W for CCTV surveillance, we can run customized Python 3 applications on a Raspberry Pi Zero W for various use cases.

Pairing the official operating system for Raspberry Pi with Python 3, we will be able to get a versatile computer to do our bidding.

Anticipating the need to setup a version of Raspbian Lite on Raspberry Pi Zero W for future Python 3 projects, I created this post to document the steps of how to do so with Raspbian Stretch Lite.
