The Dog Box
This is a project to build a 12V leisure battery. The cells are manufactured by CATL and are made from lithium iron phosphate (LiFePO4). The cells are supported by a 150A BMS (Battery Management System). A suitable box was found locally at The Range and just about houses the battery, BMS and various gubbins. The Dog Box – our new ’pet’ – is ready for camping in 2022!

Build Your Own
These are the steps to create a WordPress website and webserver on a Raspberry Pi.

|---|---|
| Format SD card to FAT32 | https://www.sdcard.org/downloads/formatter/ |
| Install Raspberry Pi Imager for Windows | https://www.raspberrypi.com/software/ |
| Select OS and SD Card then click “Write” to copy image to SD card | Raspberry Pi installation |
| Insert the SD card into the Raspberry Pi and power it up; Enter user = “pi”, password (default) = “raspberry” | Raspberry Pi documentation |
| Change the default password | |
| Enable SSH | https://en.wikipedia.org/wiki/Secure_Shell |
| Find the IP address on your local network | Raspberry Pi remote access |
| Connect to Raspberry Pi from PuTTY | https://www.putty.org/ |
| Create a LAMP server (Linux, Apache, MySQL, PHP/Perl/Python) | LAMP Server |
| Choose a WordPress theme and create some content | |
| Test accessing the website on your local network | http://192.168.xxx.xxx |
| Set up a fixed IP on your home network; set up port forwarding for Port 80 & 443 on your broadband router. | Port Forwarding |
| Set up the DNS entries. This is usually where you purchased your domain name. | Type = A; Name = @; Value = [External IP address]; TTL [Leave blank] Type = CNAME; Name = www; Value = strover.com; TTL [Leave blank] |
| Check Port 80 is open; Port 443 cannot be confirmed until SSL is set up later in the process | https://www.yougetsignal.com/tools/open-ports/ |
| [Optional] Request a fixed external IP address from your broadband provider. This avoids having to use a DNS re-direction service. If not, you will need to maintain periodic updates to your external IP address at the domain manager whenever your broadband provider changes your external IP address. | |
| Amend Settings/General in WordPress: WordPress Address (URL) and Site Address (URL) to “http://strover.com” | This converts the URL from being identified with 192.168.xxx.xxx to your chosen domain name |
| Use Better Search Replace plugin in WordPress to fix broken links when moving from local IP to strover.com | https://wordpress.org/plugins/better-search-replace/ |
| Set up SSL Encryption to change the http:// to https:// | https://pimylifeup.com/raspberry-pi-ssl-lets-encrypt/ |
| Amend Settings/General in WordPress: WordPress Address (URL) and Site Address (URL) to “https://strover.com” | https://wordpress.org/support/article/changing-the-site-url/ |
| Use Better Search Replace plugin in WordPress to fix any broken links | |
| Install Akismet Antispam plugin to WordPress | https://wordpress.org/plugins/akismet/ |
| Back up the website via SSH connection using PuTTY and create the back up files. | cd /var/www sudo tar -cpvzf html-backup-$(date +%F).tar.gz \ –exclude=’html/wp-content/cache’ \ –exclude=’html/wp-content/aiowps_backups’ \ –exclude=’html/wp-content/updraft’ \ html |
| Use FileZilla via SFTP to copy the backup files to your PC. Connect to IP address on port 22; Navigate to /home/pi | https://filezilla-project.org/ |
| Restore the database back up | sudo mysql -u root -p wordpress < wordpress.sql |
| Unzip back up to a new directory | sudo mkdir -p /var/www/html/restore/ sudo tar -cpvzf html-backup-$(date +%F).tar.gz -C /var/www/html/restore/ |
| Verify the files in the new directory | ls -l /var/www/html/restore/ |
| Remove previous files from website back-up process | sudo rm wordpress.sql sudo rm strover.tar.gz |
