Introduction

This is a example OpenBSD 3.9 installation of Instiki wiki using lighttpd and fastCGI as front end. The instiki wiki is used as a public web page for my local surf club (SurfclubKlagshamn). Instiki is a Ruby On Rails application which uses a MySQL database for persistent storage. Everything is free for non-commercial use as this is.

Many steps are included in the description below but most likely not all. Anyway this could probably be used as some guidance when trying to setup a similar server as I did.

Configure DNS, order domain etc.

• Add a "Custom DNS" account at DynDNS
• Order Beginner Linux webhotel at Crystone.se
• Change DNS för host surfclubklagshamn.se to DynDNS instead of Crystone.

Temprary password must be obtained using reset mail address att NIC-SE.

ns1.mydyndns.org 63.208.196.92

ns3.mydyndns.org 63.209.15.211
ns4.mydyndns.org 213.155.150.206
ns5.mydyndns.org 63.208.196.93

(change takes about 24h to take effect)

• Upload public key, ~/.ssh/id_dsa.pub, to backup server using e.g. sftp.

• Add id_dsa.pub contents to ~/.ssh/authorized_keys (file may not exist and must then be created)

cat id_dsa.pub >> .ssh/authorized_keys

bla, bla

• Add backup.sh file to /etc/weekly script
