DESCRIPTION ¶

Setup instructions for this server:

• Raspberry Pi Zero W

• traffic proxied from CloudFlare using cloudflared

• git

BUILDING ¶

Cross-compile binaries for the Raspberry Pi.

cloudflared ¶

$ git clone https://github.com/cloudflare/cloudflared/
$ cd cloudflared
$ GOARCH=arm CGO_ENABLED=0 go build -trimpath -ldflags "-s -w"

INSTALLATION ¶

Create Git Repository ¶

Install Git ¶

$ apt install git

Create Git Repository ¶

On the raspberry pi, create the:

• bare git repository

• www directory for serving pages

Set the permissions to allow an unprivileged user to push updates. When changes are pushed, a git hook runs and checks out the files to the www root directory.

$ mkdir /opt/git /opt/www
$ chmod g+w /opt/git /opt/www
$ chgrp sudo /opt/git /opt/www
$ git init --bare --shared /opt/git/crashonly.com
$ chgrp -R sudo /opt/git/crashonly.com

$ mkdir /opt/www/crashonly.com
$ chmod 2775 /opt/www/crashonly.com
$ chgrp sudo /opt/www/crashonly.com

Create Git Hook ¶

$ vi /opt/git/crashonly.com/hooks/post-receive
$ chmod +x /opt/git/crashonly.com/hooks/post-receive

#!/bin/sh

set -e

umask 0002
GIT_WORK_TREE=/opt/www/crashonly.com git checkout -f
