Switching the Raspberry Pi WordPress Site to Hugo

Thu, 09 Jul 2026 00:00:00 +0900

I already wrote about migrating the article data from WordPress to Hugo in Migrating from WordPress to Hugo.

This article covers the next step: switching the actual WordPress environment running on my Raspberry Pi to Hugo.

Even when I built the environment myself, I forget the details after enough time passes. Looking back at my older notes, this site was not running WordPress directly on the host with PHP and MySQL. It was running through Docker.

[Raspberry Pi 4] USB Boot: Stop Using an SD Card and Boot from an SSD

Thu, 06 Jan 2022 17:12:07 +0900

This is a memo from migrating a Raspberry Pi web server that had been running from an SD card to an SSD with USB boot. I had written about something similar before; this time only the data-copying method is different. This procedure may be easier.
The steps are for Ubuntu, but I think almost the same method can be used with Raspberry Pi OS. This is amateur work, so follow it at your own risk if you use it as a reference.

[Raspberry Pi 4] Four-Channel Terrestrial Digital Recording Server on a Raspberry Pi: Docker + GPU Encoding Version

Sat, 18 Sep 2021 08:30:00 +0900

This is a memo for enabling hardware encoding in EPGStation running on a Raspberry Pi. It continues from the previous article, [Raspberry Pi 4] Four-Channel Terrestrial Digital Recording Server on Ubuntu with PX-Q1UD. Some parts still do not work perfectly, but the GPU appears to be usable, and it is mostly operational now.

This is amateur work, so follow it at your own risk if you use it as a reference.

[Raspberry Pi 4] Headless Install of 64-bit Raspberry Pi OS (No Monitor or Keyboard Needed)

Fri, 17 Sep 2021 00:24:18 +0900

I only recently noticed that Raspberry Pi OS has a 64-bit version, so I will install it on a Raspberry Pi 4. As usual, this assumes no keyboard, mouse, or display is connected to the Raspberry Pi.

Like when installing Ubuntu, this records the steps up to installing the OS and logging in from the host PC (Windows) over SSH. This time I use an SSD for storage instead of an SD card.

[Raspberry Pi 4] Install Docker on the 64-bit Version of Raspberry Pi OS

Tue, 14 Sep 2021 13:51:47 +0900

This is a memo. It is the same procedure as installing on Ubuntu. The repository URL is about the only difference.

Test Environment

Raspberry Pi 4, 8GB memory
*On this site, I use a SanDisk SSD and a Buffalo SSD for storage. (Reference: [Raspberry Pi 4] Change the Pi 4 Storage from an SD Card to an SSD)

[Raspberry Pi 4] Four-Channel Simultaneous Terrestrial Digital TV Recording Server on Ubuntu with PX-Q1UD

Sat, 19 Jun 2021 00:21:28 +0900

These are notes. I tried something called a recording server. Since I already had a Docker environment, it was easy to create. I also tried hardware encoding, but it was not stable, so these notes only cover building the normal setup. This is amateur work, so if you use it as a reference, do so at your own risk.

Update: In a separate article, I wrote about operating it with H/W encoding.

[Raspberry Pi 4] Install Docker on Ubuntu Server 21.04

Tue, 08 Jun 2021 02:10:55 +0900

This is a memo. Since Ubuntu Hirsute 21.04 is already installed on the Raspberry Pi, installing Docker only requires following the procedure on the official site.

Test Environment

Raspberry Pi 4, 4GB memory

Ubuntu Server 21.04

Install Docker

# 旧バージョン等のクリーンアップ
$ sudo apt-get remove docker docker-engine docker.io containerd runc

# Set up the repository
$ sudo apt-get update
$ sudo apt-get install -y 

apt-transport-https 

ca-certificates 

curl 

gnupg

[Raspberry Pi 4] Headless Installation of Ubuntu Server 21.04 Over Wi-Fi Only (No Monitor or Keyboard) 🐣 Beginner-Friendly 🐣
Mon, 07 Jun 2021 11:48:41 +0900
I got a 4 GB memory version of the Raspberry Pi 4, so I tried a headless installation of Ubuntu Server 21.04. For now, I will record the steps from installing the OS to logging in by SSH from the host PC.
Environment Tested
Raspberry Pi 4, 4 GB memory
Transcend microSD 128GB

[Raspberry Pi] After Setting Up a Ramdisk, nginx Stopped Starting, So I Handled It with rc-local
Fri, 19 Mar 2021 08:06:00 +0900
This is just about trying an earlier article, [Ubuntu] After Setting Up a Ramdisk on Raspberry Pi, nginx and MySQL Stopped Starting, So I Handled It with rc-local, on a Raspberry Pi 4 as well. These days MySQL runs in a Docker container, so the only target this time is /var/log/nginx.


[Raspberry Pi 4] Run WordPress with Docker
Sat, 13 Mar 2021 13:19:49 +0900
Overview
These are notes from setting up WordPress with Docker. Nginx is already running on the host side, and an SSL certificate has already been obtained, so WordPress will ride on that setup too.

[Raspberry Pi 4] Build a Mail Server (Postfix + Dovecot) with Docker
Tue, 02 Feb 2021 09:55:54 +0900
This time, I use Docker to start a mail server and handle the various settings around it.
Overview
I use Postfix and Dovecot for my home mail server, but when installed as native packages, the initial configuration is complicated. When rebuilding the server or moving it to another PC, I completely forget what was configured and how. On top of that, I also need to configure other tools such as spam countermeasures and Fail2Ban, so it is a real hassle. This time the goal is an easy installation using Docker.


[Raspberry Pi 4] Install Nginx and Obtain an SSL Server Certificate from Let's Encrypt
Sat, 23 Jan 2021 17:54:14 +0900
Overview
Since I installed Ubuntu 20.10 on a Raspberry Pi 4, I migrated the mail server and WordPress running on my current home server over to the Raspberry Pi. These are my notes.
Environment Tested
Raspberry Pi 4 Ubuntu 20.10 (arm64)
$ nginx -v
nginx version: nginx/1.18.0 (Ubuntu)
$ certbot --version
certbot 1.11.0
Prerequisites and Preparation
Complete the Ubuntu installation, PPPoE settings, and domain settings in advance. This is the same as what I did previously on the Pi 3, so I will omit the details.


[Raspberry Pi 4] Headless Installation of Ubuntu 20.10: Installing Without a Keyboard or Display
Tue, 12 Jan 2021 08:07:00 +0900
Overview
This is about installing Ubuntu 20.10 on a Raspberry Pi 4. I did not have a MicroHDMI cable, so I installed and performed the initial setup without connecting a keyboard or display.
I install Ubuntu and make it possible to log in by SSH from a PC, while using the Cloud-init (user-data) mechanism so that as little work as possible is needed after boot.
In a previous article, after installing and booting Ubuntu, various settings still had to be done. This procedure automates that part: [Raspberry Pi 3] Installing Ubuntu 18.04 LTS (no keyboard or display required)

To extend the life of the Raspberry Pi SD card, I made /var/log a Ramdisk, and then nginx and MySQL stopped starting. The cause was simple: directories such as /var/log/nginx and /var/log/mysql did not exist when the processes started.

[Raspberry Pi 3] How to Change Only the Ubuntu Username Without Changing the User ID (uid)
Sat, 14 Mar 2020 20:09:17 +0900
This continues from [Raspberry Pi 3] Installing Ubuntu 18.04 LTS (No Keyboard or Display Required).
Leaving the user and password as ubuntu/ubuntu is dangerous, so this is about changing them for now.
Creating a new user and then deleting the ubuntu user would be fine too, but I tried changing only the name while keeping uid=1000 and gid=1000.
Test Environment
Raspberry Pi 3
Ubuntu 18.04.04 LTS 32-bit
How to Do It
You need to log in as root before doing the work, so it may be a little more troublesome than adding a new user and deleting the ubuntu user.
