Borgbot

Michael here documenting the install of a "borgbot" to do two things

• receive backups of sandboxes
• service static snapshots of retired sandboxes

Here are the steps:

• Installed a Pi with "fresh" raspian lite
• did apt-get update / upgrade
• raspi-config to enable ssh
• Install Tinc + adding a new node
  • it's convenient to ssh to the pi from a laptop that can also ssh to xpub to copy and paste the invite code
• install borgbackup

fish

   apt-install fish
   which fish
   chsh

and enter /usr/bin/fish

mount/fstab

Despite the (too) many ads, this page gives a pretty good discussion of mounting a drive. Also how-to-write-an-fstab-file-on-linux is maybe even better.

   sudo mkdir /mnt/usb
   sudo mount /dev/sda1 /mnt/usb

   cat /etc/mtab

   sudo lsblk
   sudo nano /etc/fstab

nginx

Install nginx

   sudo apt-get install nginx

Configure to serve sandboxes.

server {
	listen 80 default_server;
	listen [::]:80 default_server;

	root /var/www/html;
	# root /mnt/usb/sandboxes;
	
	# Add index.php to the list if you are using PHP
	# index index.html index.htm index.nginx-debian.html;
	index index.html;
	
	server_name _;

	location /sandbot/ {
		 # rewrite_log on;
		 autoindex on;
		 # rewrite ^/sandbot/(.*?)/$ /$1/index.html break;
		 rewrite ^/sandbot/(.*)$ /$1 break;
		 root /mnt/usb/sandboxes/sandbot/var/www/html;
		 try_files $uri ${uri}index.html $uri/index.html $uri/ =404;
		 index index.html;
		 # First attempt to serve request as file, then
		 # as directory, then fall back to displaying a 404.
	}
	location ~ ^/sandbot/~(.+?)(/.*)?$ {
        alias /mnt/usb/sandboxes/sandbot/home/$1/public_html$2;
        index index.html index.htm;
        autoindex on;
    }
}
