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 reflect cart count at the cart icon as and when products are added or removed from the cart in WooCommerce

Although there is a hassle free option of using WooCommerce.com as your e-commerce store, you may prefer to host your own.

If you are familiar with WordPress and wish to host your e-commerce website, WooCommerce is also available as a WordPress plugin that augments WordPress with e-commerce website features.

Although more work needs to be done for self-hosted WordPress sites, we have the option of creating our own themes without having to pay additional charges on top of the web hosting fees.

When it comes to creating our own WooCommerce themes, one feature that we may want to implement would be to show the number of products that had been added to our WooCommerce cart near the shopping cart icon as and when products are added or removed from the cart.

This post documents how we can reflect cart count at the cart icon as and when products are added or removed from the WooCommerce shopping cart.

Setting up WordPress on Raspberry Pi 3 with Raspbian Stretch Lite, Nginx, MariaDB and PHP 7 as the LEMP stack

Raspbian Stretch was released on 17th August 2017 and this will mean that we will be able to get a variant of Debian 9 on our Raspberry Pi. With Raspbian Stretch, we will be able to run WordPress or any PHP framework with PHP 7.0 which Zend had indicated a performance boost of up to two folds as compared to PHP 5.6.

Just like the benefits that blogging brings to a programmer, the performance boost that PHP 7 brings about is a good reason for me to port my blog over to PHP 7.

Before porting my blog over to PHP 7, it will make sense for me to perform a little proof of concept on my Raspberry Pi 3 first. With Raspbian Stretch Lite, I can see for myself that my blog runs well with PHP 7.0 before spawning a new Digital Ocean instance for Techcoil.

This post documents how I setup an instance of WordPress on Raspberry Pi 3 with Raspbian Stretch Lite, nginx, MariaDB and PHP 7 as the LEMP stack.

Setting up ProjectSend on your Raspberry Pi 3 for sharing files – the LEMP way

Do you have large files that you want to share with your friends or clients? Do you keep your Internet connection on 24-7?

Compared to using Google Drive, Dropbox or other on-the-cloud file sharing software, hosting your own file sharing software when you never switch off your Internet has a few advantages.

Provided that your friends don’t share your files with others, your files stay at home and on your friends’ machines. Furthermore, you are only limited by the amount of storage that you have on your machine.

If you have a Raspberry Pi 3 in your house, you may want to consider setting up ProjectSend on your Raspberry Pi 3 for sharing files with others. This post shows how to do it with a LEMP stack.

How I setup Codiad web IDE on my Raspberry Pi 3 with Ubuntu Server 15.10.3, Nginx and PHP

There are times when I get the urge to work on project source codes that reside on my Raspberry Pi 3 LEMP server while I am on the move. Setting up a web based IDE on my Raspberry Pi 3 is one way to enable me to code while I am on the move, so long as I have a device with a web browser that is connected to the internet. Since I had already setup a LEMP server to run WordPress on my Raspberry Pi 3 and that Codiad is written in PHP, Codiad is an ideal web based IDE that I can set up on my Raspberry Pi 3.

This post documents how I setup Codiad web IDE on my Raspberry Pi 3. To make this post complete, I had taken some of the steps mentioned in my other posts on Raspberry Pi and replicated it in this post.
