Setting up CGI (nginx)

Running something as www-data

 sudo su www-data -s /bin/sh

Setting up /var/www/html with githook:

 sudo chown www-data /var/www/html
 git remote set-url origin https://git.xpub.nl/XPUB/sandbot.git

Created file /usr/lib/cgi-bin/pull_XXXXXXXXXX.cgi

#!/bin/bash

echo "Content-type:text/html"
echo
cd /var/www/html
git fetch --all
git reset --hard origin/master

Testing the webhook...

sudo su www-data -s /bin/sh
cd /usr/lib/cgi-bin
./pull_XXXXXX.cgi
