Migrating from WordPress to Hugo

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

I decided to migrate this site, which had been running on WordPress, to Hugo.

WordPress is convenient. You can write posts from the admin screen, and there are many themes and plugins. But after running it for a long time, the number of things to maintain keeps growing little by little: PHP, MySQL, plugins, themes, security updates, backups, and so on.

This blog is mostly a place where I leave notes about things I looked up. I do not need much dynamic behavior. For that kind of use, managing posts as Markdown files and publishing static HTML with Hugo feels like a better fit.

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] 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.

Environment Tested

Raspberry Pi 4 Ubuntu 20.10 (arm64)

[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.

[WordPress] Change VCCW's PHP Version to 7.4

Fri, 03 Apr 2020 12:25:13 +0900

The VCCW environment I use to verify WordPress behavior had a different PHP version from production, so I aligned them.

Method

Change the PHP version installed in VCCW
The author of VCCW provides the method, so I followed it.

To apply it to an already running VCCW environment, log in to the guest OS with vagrant ssh and run the following command.

WordPress: How to Paste Code Between the and Tags in the Cocoon Child Theme

Sun, 23 Feb 2020 00:19:05 +0900

I use the Cocoon Child theme. I did not know how to put the Google Adsense code inside the <head> tag, so I looked it up.

*Update: You can now change this from the settings screen, so I added notes about that too.

Configuration

In the WordPress dashboard, open Appearance -> Theme Editor.
From the theme file list on the right, select tmp-user -> head-insert.php.
At the bottom there is a line that says <? //全ての訪問者をカウントする場合は以下に挿入 ?>. Paste the code you want to insert below that line.
Press the Update File button at the bottom of the screen, and you are done.

head-insert.php Configuration Example

<?php
//ヘッダー部分（<head></head>内）にタグを挿入したいときは、このテンプレートに挿入（ヘッダーに挿入する解析タグなど）
//子テーマのカスタマイズ部分を最小限に抑えたい場合に有効なテンプレートとなります。
//例：<script type="text/javascript">解析コード</script>
?>
<?php if (!is_user_administrator()) :
//管理者を除外してカウントする場合は以下に挿入 ?>
<?php endif; ?>
<?php //全ての訪問者をカウントする場合は以下に挿入 ?>
<script data-ad-client=“ca-pub-XXXXXXX” async src=“https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

I Tried Using the Relaxed Kosugi Maru Web Font (Google Font) in a WordPress Theme

Sat, 22 Feb 2020 21:26:55 +0900

I tried configuring a web font in WordPress. This time I used Kosugi Maru from Google Fonts.
The theme for this site is Cocoon Child, but I think the basics are the same for other themes.
No additional plugins are required.

Configuration

Open Appearance -> Customize -> Additional CSS from the dashboard.
There is an input area on the left, so add the font settings there.
A preview is displayed as soon as you enter it, which makes it easy to see what changed.

Configuration Example

This time I configured it as follows.
The only key points are "fetch the font with @import" and "apply it to the style with font-family:", so the setup is simple.
