I wanted to be able to add content here without having to SSH into
cd-ing into the www directory,
git pulling, and
as those steps are tedious. So, I set up a GitHub webhook to POST to a PHP
page on the server. The basic form of this PHP page is just:
<?php passthru("MYSCRIPT.sh"); ?>
MYSCRIPT.sh is just a script that pulls and makes the site.
Now, GitHub also allows you to set a secret, which allows you to secure the page against malicious actors. For this application, I find that a bit overkill (I figure the worst they can do is DOS me). Instead, I opted for rate limiting, as it is simpler to implement.
Now, whenever I push to my repo, my server will automatically pull and recompile the site, which is pretty neat.
