Let's Encrypt on Ubuntu 14.04, nginx with webroot auth

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.

As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:

Info

This guide sets up a non-clustered Nutch crawler, which stores its data via HBase. We will not learn how to setup Hadoop et al., but just the bare minimum to crawl and index websites on a single machine.

Terms

• Nutch - the crawler (fetches and parses websites)
• HBase - filesystem storage for Nutch (Hadoop component, basically)

2.4 IncrementableInterface

This interface provides the ability to increment and decrement cache entries by their specified value. Some cache backends support this natively so that you don't have to read the item and then increment it and write it back to the cache server, this can be done in a single call to the cache server since it's natively supported by many modern cache servers.

• Implementations MUST allow any integer to be incremented and decremented (i.e. decrementing 0 yields -1) by any [positive?] integer.
• If a key does not exist, implementations MUST NOT create a new cache item and instead return false.

Problem

Konkret ist der Content-Controller vom Sally-Backend problematisch. Er verlässt sich u.a. darauf, dass der nette Sally-Dispatcher seine Exceptions fängt. Das führt allerdings auch dazu, dass anstatt der "Inhalt"-Überschrift die "Unterwartete Exception"-Meldung auftaucht. Was nicht wirklich stimmt, da einige der Exceptions bewusst vom Controller geworfen werden (also nicht unerwartet sind).

Gleichzeitig taucht in vielen Controllern immer wieder das Muster auf, dass eine allgemeine init()-Methode angelegt wird, die von jeder Action als erstes aufgerufen wird. Teils ist die Methode so komplex, dass sie a) nicht mehrmals aufgerufen werden darf und b) die Ausführung der eigentlichen Action stoppen kann.
